The Redline allows the user to quickly spot changed sections and to tell specifically what has been changed from the previous edition. In using the Redline, note the following: Deleted material is shown in Fed "piketh•^6ightype. New material appears in blue underlinedtype. Together, these two comparative documents are a useful tool for interpreting code changes and staying current with ICC codes and standards. The "Redline" is intended as a convenient tool to help users compare a new edition of the International Code with the previous edition of that document and to identify and view changes and additions. Every effort has been made to provide a clear, accurate, and usable depiction of the revisions that have been made; however, it may not always be possible to depict all changes accurately or in every detail, due to the complexity of the revision process. In cases where a section requirement has not changed but the code section number has changed, the entire text will still be shown as underlined due to section number changing not necessarily because the section requirements changed. In addition, this Redline has not been updated to include any errata that may have been issued after the published date of the corresponding International Code. This Redline, therefore, is not intended to be the official version of an International Code.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER PREFACE Introduction The International Fuel Gas Code (IFGC) establishes minimum requirements for fuel gas systems and gas -fired appliances using prescriptive and performance -related provisions. It is founded on broad -based principles that make possible the use of new materials and new fuel gas system and appliance designs. This 2018 edition is fully compatible with all of the International Codes® (I -Codes) published by the International Code Council (ICC ), including the International Building Code , International Energy Conservation Code , International Existing Building Code, International Fire Code, International Green Construction Code, International Mechanical Code , International Plumbing Code , International Private Sewage Disposal Code, International Property Maintenance Code, International Residential Code, International Swimming Pool and Spa Code International Wildland-Urban Interface Code , International Zoning Code and International Code Council Performance Code . The I -Codes, including this International Fuel Gas Code, are used in a variety of ways in both the public and private sectors. Most industry professionals are familiar with the I -Codes as the basis of laws and regulations in communities across the U.S. and in other countries. However, the impact of the codes extends well beyond the regulatory arena, as they are used in a variety of nonregulatory settings, including: Voluntary compliance programs such as those promoting sustainability, energy efficiency and disaster resistance. The insurance industry, to estimate and manage risk, and as a tool in underwriting and rate decisions. Certification and credentialing of individuals involved in the fields of building design, construction and safety. Certification of building and construction -related products. U.S. federal agencies, to guide construction in an array of government -owned properties. Facilities management. "Best practices" benchmarks for designers and builders, including those who are engaged in projects in jurisdictions that do not have a formal regulatory system or a governmental enforcement mechanism. College, university and professional school textbooks and curricula. Reference works related to building design and construction. In addition to the codes themselves, the code development process brings together building professionals on a regular basis. It provides an international forum for discussion and deliberation about 2018 INTERNATIONAL FUEL GAS CODE to CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. x m.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER building design, construction methods, safety, performance requirements, technological advances and innovative products. Development This 2018 edition presents the code as originally issued, with changes reflected in the 2003 through 2015 editions and further changes approved by the ICC Code Development Process through 2017 and standard revisions correlated with ANSI Z223.1-2018. A new edition such as this is promulgated every 3 years. This code is founded on principles intended to establish provisions consistent with the scope of a fuel gas code that adequately protects public health, safety and welfare; provisions that do not unnecessarily increase construction costs; provisions that do not restrict the use of new materials, products or methods of construction; and provisions that do not give preferential treatment to particular types or classes of materials, products or methods of construction. Format The International Fuel Gas Code is segregated by section numbers into two categories —"code" and "standard" —all coordinated and incorporated into a single document. The sections that are "code" are designated by the acronym "IFGC" next to the main section number (e.g., Section 101). The sections that are "standard" are designated by the acronym "IFGS" next to the main section number (e.g., Section 304). A subsection may be individually redesignated as an "IFGS" section where it is located under an "IFGC" main section. Maintenance The International Fuel Gas Code is kept up to date through the review of proposed changes submitted by code enforcement officials, industry representatives, design professionals and other interested parties. Proposed changes are carefully considered through an open code development process in which all interested and affected parties may participate. The ICC Code Development Process reflects principles of openness, transparency, balance, due process and consensus, the principles embodied in OMB Circular A-119, which governs the federal government's use of private -sector standards. The ICC process is open to anyone; there is no cost to participate, and people can participate without travel cost through the ICC's cloud- ® based app, cdp-Access . A broad cross section of interests are represented in the ICC Code Development Process. The codes, which are updated regularly, include safeguards that allow for emergency action when required for health and safety reasons. In order to ensure that organizations with a direct and material interest in the codes have a voice in the process, the ICC has developed partnerships with key industry segments that support the ICC's important public safety mission. Some code development committee members were nominated by the following industry partners and approved by the ICC Board: 2018 INTERNATIONAL FUEL GAS CODE 5 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER • American Gas Association (AGA) American Institute of Architects (AIA) The code development committees evaluate and make recommendations regarding proposed changes to the codes. Their recommendations are then subject to public comment and council -wide votes. The ICC's governmental members —public safety officials who have no financial or business interest in the outcome —cast the final votes on proposed changes. The contents of this work are subject to change through the code development cycles and by any governmental entity that enacts the code into law. For more information regarding the code development process, contact the Codes and Standards Development Department of the International Code Council. While the I -Code development procedure is thorough and comprehensive, the ICC, its members and those participating in the development of the codes disclaim any liability resulting from the publication or use of the I -Codes, or from compliance or noncompliance with their provisions. The ICC does not have the power or authority to police or enforce compliance with the contents of this code. Code Development Committee Responsibilities (Letter Designations in Front of Section Numbers) In each code development cycle, proposed changes to the code are considered at the Committee Action Hearings by the International Fuel Gas Code Development Committee, whose action constitutes a recommendation to the voting membership for final action on the proposed change. Proposed changes to a code section that has a number beginning with a letter in brackets are considered by a different code development committee. For example, proposed changes to code sections that have [BS] in front of them (e.g., [BS] 302.1) are considered by the IBC —Structural Code Development Committee at the Committee Action Hearings. The content of sections in this code that begin with letter designations is maintained by other code development committees in accordance with the following: [A] = Administrative Code Development Committee; [BF] = IBC —Fire Safety Code Development Committee; [BG] = IBC —General Code Development Committee; [BS] = IBC —Structural Code Development Committee; [E] = International Energy Conservation Code Development Committee; [F] = International Fire Code Development Committee; and [M] = International Mechanical Code Development Committee.

Because different committees hold Committee Action Hearings in different years, it is possible that some proposals for this code will be heard by committees in both 2018 (Group A) and the 2019 (Group B) code development cycles. 2018 INTERNATIONAL FUEL GAS CODE 7 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(R dme pooch od om).(Dby of PnmdNmod)Odo,Nomb¢*10081vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to Lie Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, goodomo- by anytlt Party o, Axmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER For instance, every section of Chapter 1 of this code is designated as the responsibility of the Administrative Code Development Committee, which is part of the Group B portion of the hearings. This committee will hold its Committee Action Hearings in 2019 to consider all code change proposals for Chapter 1 of this code and proposals for Chapter 1 of all I -Codes except the International Energy Conservation Code, International Residential Code and International Green Construction Code. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Administrative Code Development Committee for consideration in 2019. It is very important that anyone submitting code change proposals understands which code development committee is responsible for the section of the code that is the subject of the code change proposal. For further information on the code development committee responsibilities, please visit the ICC website at www.iccsafe.org/scoping. Marginal Markings Solid vertical lines in the margins within the body of the code indicate a technical change from the requirements of the 2015 edition. Deletion indicators in the form of an arrow (—) are provided in the margin where an entire section, paragraph, exception or table has been deleted or an item in a list of items or a table has been deleted. Coordination of the International Codes The coordination of technical provisions is one of the strengths of the ICC family of model codes. The codes can be used as a complete set of complementary documents, which will provide users with full integration and coordination of technical provisions. Individual codes can also be used in subsets or as stand-alone documents. To make sure that each individual code is as complete as possible, some technical provisions that are relevant to more than one subject area are duplicated in some of the model codes. This allows users maximum flexibility in their application of the I -Codes. Italicized Terms Words and terms defined in Chapter 2, Definitions, are italicized where they appear in code text and the Chapter 2 definition applies. Where such words and terms are not italicized, common - use definitions apply. The words and terms selected have code -specific definitions that the user should read carefully to facilitate better understanding of the code. Adoption The International Code Council maintains a copyright in all of its codes and standards. Maintaining copyright allows the ICC to fund its mission through sales of books, in both print and electronic formats. The ICC welcomes adoption of its codes by jurisdictions that recognize and acknowledge the ICC's copyright in the code, and further acknowledge the substantial shared value of the public/private partnership for code development between jurisdictions and the ICC. The ICC also recognizes the need for jurisdictions to make laws available to the public. All (- Codes and I -Standards, along with the laws of many jurisdictions, are available for free in a nondownloadable form on the ICC's website. Jurisdictions should contact the ICC at adoptions@iccsafe.org to learn how to adopt and distribute laws based on the International Fuel Gas Code in a manner that provides necessary access, while maintaining the ICC's copyright. 2018 INTERNATIONAL FUEL GAS CODE H (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER RBPLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER EFFECTIVE USE OF THE INTERNATIONAL FUEL GAS CODE The International Fuel Gas Code (IFGC) is a model code that regulates the design and installation of fuel gas distribution piping and systems, appliances, appliance venting systems, combustion air provisions, gaseous hydrogen systems and motor vehicle gaseous -fuel - dispensing stations. The definition of fuel gas includes natural, liquefied petroleum and manufactured gases and mixtures of these gases. The purpose of the code is to establish the minimum acceptable level of safety and to protect life and property from the potential dangers associated with the storage, distribution and usage of fuel gases and the byproducts of combustion of such fuels. The code also protects the personnel that install, maintain, service and replace the systems and appliances addressed by this code. With the exception of Section 401.1.1, the IFGC does not address utility -owned piping and equipment (i.e., anything upstream of the point of delivery). See the definition of 'Point of delivery" and Section 501.8 for other code coverage exemptions. The IFGC is primarily a specification -oriented (prescriptive) code with some performance - oriented text. For example, Section 503.3.1 is a performance statement, but Chapter 5 contains prescriptive requirements that will cause Section 503.3.1 to be satisfied. The IFGC applies to all occupancies including one- and two-family dwellings and townhouses. The IRC is referenced for coverage of one- and two-family dwellings and townhouses; however, in effect, the IFGC provisions are still applicable because the fuel gas chapter in the IRC (Chapter 24) is composed entirely of text extracted from the IFGC. Therefore, whether using the IFGC or the IRC, the fuel gas provisions will be identical. The IFGC does not apply to piping systems that operate at pressures in excess of 125 psig for natural gas and 20 psig for LP -gas (note exception in Section 402.7). The general Section 105.2 and the specific Sections 304.8, 402.3, 503.5.5 and 503.6.10 allow combustion air provisions, pipe sizing and chimney and vent sizing to be performed by approved engineering methods as alternatives to the prescriptive methods in the code. Arrangement and Format of the 2018 IFGC The format of the IFGC allows each chapter to be devoted to a particular subject, with the exception of Chapter 3, which contains general subject matters that are not extensive enough to warrant their own independent chapter. Chapter 1 Scope and Administration. Chapter 1 establishes the limits of applicability of the code and describes how the code is to be applied and enforced. A fuel gas code, like any other code, is intended to be adopted as a legally enforceable document, and it cannot be effective without adequate provisions for its administration and enforcement. The provisions of Chapter 1 establish the authority and duties of the code official appointed by the authority having jurisdiction and also establish the rights and privileges of the design professional, contractor and property owner. 2018 INTERNATIONAL FUEL GAS CODE 10 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 2 Definitions. Chapter 2 is the repository of the definitions of terms used in the body of the code. Codes are technical documents and every word, term and punctuation mark can impact the meaning of the code text and the intended results. The code often uses terms that have a unique meaning in the code and the code meaning can differ substantially from the ordinarily understood meaning of the term as used outside of the code. The terms defined in Chapter 2 are deemed to be of prime importance in establishing the meaning and intent of the code text that uses the terms. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined. Chapter 3 General Regulations. Chapter 3 contains broadly applicable requirements related to appliance location and installation, appliance and systems access, protection of structural elements and clearances to combustibles, among others. This chapter also covers combustion air provisions for gas -fired appliances. Chapter 4 Gas Piping Installations. Chapter 4 covers the allowable materials for gas piping systems and the sizing and installation of such systems. It also covers pressure regulators, appliance connections and overpressure protection devices. Gas piping systems are sized to supply the maximum demand while maintaining the supply pressure necessary for safe operation of the appliances served. Chapter 5 Chimneys and Vents. Chapter 5 regulates the design, construction, installation, maintenance, repair and approval of chimneys, vents, venting systems and their connections to gas -fired appliances. Properly designed chimneys, vents and venting systems are necessary to conduct to the outdoors the flue gases produced by the combustion of fuels in appliances. The provisions of this chapter are intended to minimize the hazards associated with high temperatures and potentially toxic and corrosive combustion gases. This chapter addresses all of the factory -built and site -built chimneys, vents and venting systems used to vent all types and categories of appliances. It also addresses direct -vent appliances, integral vent appliances, side -wall mechanically vented appliances and exhaust hoods that convey the combustion byproducts from cooking and other process appliances. Chapter 6 Specific Appliances. Chapter 6 addresses specific appliances that the code intends to regulate. Each main section applies to a unique type of gas -fired appliance and specifies the product standards to which the appliance must be listed. The general requirements found in the previous Chapters 1 through 5 also apply and the sections in Chapter 6 add the special requirements that are specific to each type of appliance. Chapter 7 Gaseous Hydrogen Systems. Chapter 7 is specific to gaseous hydrogen generation, storage, distribution and utilization systems, appliances and equipment. Note that hydrogen is not within the definition of "Fuel gas," but it is, nonetheless, commonly used as a fuel for fuel -cell power generation and fuel -cell powered motor vehicles. The scope of Chapter 7 is not limited to any particular use of hydrogen (see Sections 633 and 635). Hydrogen systems have unique potential hazards because of the specific gravity of the gas, its chemical effect on materials and the fact that it is not odorized. 2018 INTERNATIONAL FUEL GAS CODE 11 CITFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Chapter 8 lists all of the product and installation standards and codes that are referenced throughout Chapters 1 through 7. As stated in Section 102.8, these standards and codes become an enforceable part of the code (to the prescribed extent of the reference) as if printed in the body of the code. Chapter 8 provides the full title and edition year of the standards and codes in addition to the address of the promulgators and the section numbers in which the standards and codes are referenced. Appendix A Sizing and Capacities of Gas Piping. This appendix is informative and not part of the code. It provides design guidance, useful facts and data and multiple examples of how to apply the sizing tables and sizing methodologies of Chapter 4. Appendix B Sizing of Venting Systems Serving Appliances Equipped with Draft Hoods, Category I Appliances and Appliances Listed for Use with Type B Vents. This appendix is informative and not part of the code. It contains multiple examples of how to apply the vent and chimney tables and methodologies of Chapter 5. Appendix C Exit Terminals of Mechanical Draft and Direct -vent Venting Systems. This appendix is informative and not part of the code. It consists of a figure and notes that visually depict code requirements from Chapter 5 for vent terminals with respect to the openings found in building exterior walls. Appendix D Recommended Procedure for Safety Inspection of an Existing Appliance Installation. This appendix is informative and not part of the code. It provides recommended procedures for testing and inspecting an appliance installation to determine if the installation is operating safely and if the appliance is in a safe condition. 2018 INTERNATIONAL FUEL GAS CODE 12 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No FLths[TAodomo,,mAt,Tgoodomo,o by anytlt Party oT ATmboemdm6A[vsd Mgle ass¢ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX A(IFGS) SIZING AND CAPACITIES OF GAS PIPING This appendix is informative and is not part of the code. User note: About this appendix. Appendix A provides commentary, guidance and examples for sizing of gas piping systems. A.1 General piping considerations. The first goal of determining the pipe sizing for a fuel gas piping system is to make sure that there is sufficient gas pressure at the inlet to each appliance. The majority of systems are residential and the appliances will all have the same, or nearly the same, requirement for minimum gas pressure at the appliance inlet. This pressure will be about 5-inch water column (w.c.) (1.25 kPa), which is enough for proper operation of the appliance regulator to deliver about 3.5-inches water column (w.c.) (875 kPa) to the burner itself. The pressure drop in the piping is subtracted from the source delivery pressure to verify that the minimum is available at the appliance. There are other systems, however, where the required inlet pressure to the different appliances may be quite varied. In such cases, the greatest inlet pressure required must be satisfied, as well as the farthest appliance, which is almost always the critical appliance in small systems. There is an additional requirement to be observed besides the capacity of the system at 100-percent flow. That requirement is that at minimum flow, the pressure at the inlet to any appliance does not exceed the pressure rating of the appliance regulator. This would seldom be 1 of concern in small systems if the source pressure is / psi (14-inchw.c.) (3.5 kPa) or less but it 2 should be verified for systems with greater gas pressure at the point of supply To determine the size of piping used in a gas piping system, the following factors must be considered: (1) Allowable loss in pressure from point of deliveryto appliance. (2) Maximum gas demand. (3) Length of piping and number of fittings. (4) Specific gravity of the gas. (5) Diversity factor. 2018 INTERNATIONAL FUEL GAS CODE 260 (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1vmv 01 JM 15. x m.o oc ss AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.mfwlh¢Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER For any gas piping system, or special appliance, or for conditions other than those covered by the tables provided in this code, such as longer runs, greater gas demands or greater pressure drops, the size of each gas piping system should be determined by standard engineering practices acceptable to the code official. A.2 Description of tables. A.2.1 General. The quantity of gas to be provided at each outlet should be determined, whenever possible, directly from the manufacturer's gas input Btu/h rating of the appliance that will be installed. In case the ratings of the appliances to be installed are not known, Table 402.2 shows the approximate consumption (in Btu per hour) of certain types of typical household appliances. To obtain the cubic feet per hour of gas required, divide the total Btu/h input of all appliances by the average Btu heating value per cubic feet of the gas. The average Btu per cubic feet of the gas in the area of the installation can be obtained from the serving gas supplier. A.2.2 Low pressure natural gas tables. Capacities for gas at low pressure [less than 2.0 psig (13.8 kPa gauge)] in cubic feet per hour of 0.60 specific gravity gas for different sizes and lengths are shown in Tables 402.4(1) through 402.4(4) for iron pipe or equivalent rigid pipe; in Tables 402.4(8) through 402.4(11) for smooth wall semirigid tubing; in Tables 402.4(20) through 402.4(24) for polyethylene pipe and tubing; and in Tables 402.4(15) through 402.4(17) for corrugated stainless steel tubing. Tables 402.4(1), 402.4(61n) and 402.4(20) are based upon a pressure drop of 0.3-inch w.c. (75 Pa), whereas Tables 402.4(2), 402.4(9), 402.4(15) and 402.4(21) are based upon a pressure drop of 0.5-inch w.c. (125 Pa). Tables 402.4(3), 402.4(4), 402.4(10), 402.4(11), 402.4(16) and 402.4(17) are special low-pressure applications based upon pressure drops greater than 0.5- inch w.c. (125 Pa). In using these tables, an allowance (in equivalent length of pipe) should be considered for any piping run with four or more fittings (see Table A.2.2). 2018 INTERNATIONAL FUEL GAS CODER 261 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER RBPLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Gas piping systems that are to be supplied with gas of a specific gravity of 0.70 or less can be sized directly from the tables provided in this code, unless the code official specifies that a gravity factor be applied. Where the specific gravity of the gas is greater than 0.70, the gravity factor should be applied. Application of the gravity factor converts the figures given in the tables provided in this code to capacities for another gas of different specific gravity.

Capacities for gas at pressures 2.0 psig (13.8 kPa) or greater in cubic feet per hour of 0.60 specific gravity gas for different sizes and lengths are shown in Tables 402.4(5) through 402.4(7) for iron pipe or equivalent rigid pipe; Tables 402.4(12) to 402.4(14) for semirigid tubing; Tables 402.4(18) and 402.4(19) for corrugated stainless steel tubing; and Table 402.4(22) for polyethylene plastic pipe. A.3 Use of capacity tables. A.3.1 Longest length method. This sizing method is conservative in its approach by applying the maximum operating conditions in the system as the norm for the system and by setting the length of pipe used to size any given part of the piping system to the maximum value. To determine the size of each section of gas piping in a system within the range of the capacity tables, proceed as follows (also see sample calculations included in this Appendix): (1) Divide the piping system into appropriate segments consistent with the presence of tees, branch lines and main runs. For each segment, determine the gas load (assuming all appliances operate simultaneously) and its overall length. An allowance (in equivalent length of pipe) as determined from Table A.2.2 shall be considered for piping segments that include four or more fittings. (2) Determine the gas demand of each appliance to be attached to the piping system. Where Tables 402.4(1) through 402.4(24) are to be used to select the piping size, calculate the gas demand in terms of cubic feet per hour for each piping system outlet. Where Tables 402.4(25) through 402.4(37) are to be used to select the piping size, calculate the gas demand in terms of thousands of Btu per hour for each piping system outlet. 2018 INTERNATIONAL FUEL GAS CODE 265 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER (3) Where the piping system is for use with other than undiluted liquefied petroleum gases, determine the design system pressure, the allowable loss in pressure (pressure drop), and specific gravity of the gas to be used in the piping system. (4) Determine the length of piping from the point of delivery to the most remote outlet in the building/ piping system. (5) In the appropriate capacity table, select the row showing the measured length or the next longer length if the table does not give the exact length. This is the only length used in determining the size of any section of gas piping. If the gravity factor is to be applied, the values in the selected row of the table are multiplied by the appropriate multiplier from Table A.2.4. (6) Use this horizontal row to locate ALL gas demand figures for this particular system of piping. (7) Starting at the most remote outlet, find the gas demand for that outlet in the horizontal row just selected. If the exact figure of demand is not shown, choose the next larger figure left in the row. (8) Opposite this demand figure, in the first row at the top, the correct size of gas piping will be found. (9) Proceed in a similar manner for each outlet and each section of gas piping. For each section of piping, determine the total gas demand supplied by that section. Where a large number of piping components (such as elbows, tees and valves) are installed in a pipe run, additional pressure loss can be accounted for by the use of equivalent lengths. Pressure loss across any piping component can be equated to the pressure drop through a length of pipe. The equivalent length of a combination of only four elbows/tees can result in a jump to the next larger length row, resulting in a significant reduction incapacity. The equivalent lengths in feet shown in Table A.2.2 have been computed on a basis that the inside diameter corresponds to that of Schedule 40 (standard -weight) steel pipe, which is close enough for most purposes involving other schedules of pipe. Where a more specific solution for equivalent length is desired, this can be made by multiplying the actual inside diameter of the pipe in inches by n/12, or the actual inside diameter in feet by n (n can be read from the table heading). The equivalent length values can be used with reasonable accuracy for copper or copper alloy fittings and bends although the resistance per foot of copper or copper alloy pipe is less than that of steel. For copper or copper alloy valves, however, the equivalent length of pipe should be taken as 45 percent longer than the values in the table, which are for steel pipe. 2018 INTERNATIONAL FUEL GAS CODER 266 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER A.3.2 Branch length method. This sizing method reduces the amount of conservatism built into the traditional Longest Length Method. The longest length as measured from the meter to the furthest remote appliance is only used to size the initial parts of the overall piping system. The Branch Length Method is applied in the following manner: (1) Determine the gas load for each of the connected appliances. (2) Starting from the meter, divide the piping system into a number of connected segments, and determine the length and amount of gas that each segment would carry assuming that all appliances were operated simultaneously. An allowance (in equivalent length of pipe) as determined from Table A.2.2 should be considered for piping segments that include four or more fittings. (3) Determine the distance from the outlet of the gas meter to the appliance furthest removed from the meter. (4) Using the longest distance (found in Step 3), size each piping segment from the meter to the most remote appliance outlet. (5) For each of these piping segments, use the longest length and the calculated gas load for all of the connected appliances for the segment and begin the sizing process in Steps 6 through 8. (6) Referring to the appropriate sizing table (based on operating conditions and piping material), find the longest length distance in the first column or the next larger distance if the exact distance is not listed. The use of alternative operating pressures or pressure drops will require the use of a different sizing table, but will not alter the sizing methodology. In many cases, the use of alternative operating pressures or pressure drops will require the approval of both the code official and the local gas serving utility. (7) Trace across this row until the gas load is found or the closest larger capacity if the exact capacity is not listed. (8) Read up the table column and select the appropriate pipe size in the top row. Repeat Steps 6, 7 and 8 for each pipe segment in the longest run. (9) Size each remaining section of branch piping not previously sized by measuring the distance from the gas meter location to the most remote outlet in that branch, using the gas load of attached appliances and following the procedures of Steps 2 through 8. 2018 INTERNATIONAL FUEL GAS CODE 267 CITFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER RBPLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER A.3.3 Hybrid pressure method. The sizing of a 2 psi (13.8 kPa) gas piping system is performed using the traditional Longest Length Method but with modifications. The 2 psi (13.8 kPa) system consists of two independent pressure zones, and each zone is sized separately. The Hybrid Pressure Method is applied as follows: The sizing of the 2 psi (13.8 kPa) section (from the meter to the line regulator) is as follows: (1) Calculate the gas load (by adding up the name plate ratings) from all connected appliances. (In certain circumstances the installed gas load can be increased up to 50 percent to accommodate future addition of appliances.) Ensure that the line regulator capacity is adequate for the calculated gas load and that the required pressure drop 3 (across the regulator) for that capacity does not exceed / psi (5.2 kPa) for a 2 psi (13.8 kPa) system. If the pressure drop across the regulator is too high (for the connected gas load), select a larger regulator. (2) Measure the distance from the meter to the line regulator located inside the building. (3) If there are multiple line regulators, measure the distance from the meter to the regulator furthest removed from the meter. (4) The maximum allowable pressure drop for the 2 psi (13.8 kPa) section is 1 psi (6.9 kPa). (5) Referring to the appropriate sizing table (based on piping material) for 2 psi (13.8 kPa) systems with a 1 psi (6.9 kPa) pressure drop, find this distance in the first column, or the closest larger distance if the exact distance is not listed. (6) Trace across this row until the gas load is found or the closest larger capacity if the exact capacity is not listed. (7) Read up the table column to the top row and select the appropriate pipe size. (8) If there are multiple regulators in this portion of the piping system, each line segment must be sized for its actual gas load, but using the longest length previously determined above. The low pressure section (all piping downstream of the line regulator) is sized as follows: (1) Determine the gas load for each of the connected appliances. (2) Starting from the line regulator, divide the piping system into a number of connected segments or independent parallel piping segments, and determine the amount of gas that each segment would carry assuming that all appliances were operated simultaneously. An allowance (in equivalent length of pipe) as determined from Table A.2.2 should be considered for piping segments that include four or more fittings. (3) For each piping segment, use the actual length or longest length (if there are sub- branchlines) and the calculated gas load for that segment and begin the sizing process as follows: 2018 INTERNATIONAL FUEL GAS CODER 268 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX B (IFGS) SIZING OF VENTING SYSTEMS SERVING APPLIANCES EQUIPPED WITH DRAFT HOODS, CATEGORY I APPLIANCES AND APPLIANCES LISTED FOR USE WITH TYPE B VENTS This appendix is informative and is not part of the code. User note: About this appendix. Appendix B provides commentary, guidance and examples for the design of venting systems for the types of appliances that vent by natural draft and have draft hoods or are listed as Category l or are listed for use with Type B vents. EXAMPLES USING SINGLE APPLIANCE VENTING TABLES Example 1: Single draft -hood -equipped appliance. An installer has a 120,000 British thermal unit (Btu) per hour input appliance with a 5-inch- diameter draft hood outlet that needs to be vented into a 10-foot-high Type B vent system. What size vent should be used assuming (a) a 5-foot lateral single -wall metal vent connector is used with two 90-degree elbows, or (b) a 5-foot lateral single -wall metal vent connector is used with three 90-degree elbows in the vent system? Solution: Table 504.2(2) should be used to solve this problem, because single -wall metal vent connectors are being used with a Type B vent. (a) Read down the first column in Table 504.2(2) until the row associated with a 10-foot height and 5-foot lateral is found. Read across this row until a vent capacity greater than 120,000 Btu per hour is located in the shaded columns labeled "NAT Max" for draft - hood -equipped appliances. In this case, a 5-inch-diameter vent has a capacity of 122,000 Btu per hour and can be used for this application. (b) If three 90-degree elbows are used in the vent system, then the maximum vent capacity listed in the tables must be reduced by 10 percent (see Section 504.2.3 for single appliance vents). This implies that the 5-inch-diameter vent has an adjusted capacity of only 110,000 Btu per hour. In this case, the vent system must be increased to 6 inches in diameter (see calculations below). 2018 INTERNATIONAL FUEL GAS CODE 283 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. x m.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 122,000 (.90) = 110,000 for 5-inch vent From Table 504.2(2), Select 6-inch vent 186,000 (.90) = 167,000; This is greater than the required 120,000. Therefore, use a 6-inch vent and connector where three elbows are used. Example 2: Single fan -assisted appliance. An installer has an 80,000 Btu per hour input fan -assisted appliance that must be installed using 10 feet of lateral connector attached to a 30-foot-high Type B vent. Two 90 _degree elbows are needed for the installation. Can a single -wall metal vent connector be used for this application? Solution: Table 504.2(2) refers to the use of single -wall metal vent connectors with Type B vent. In the first column find the row associated with a 30-foot height and a 10-foot lateral. Read across this row, looking at the FAN Min and FAN Max columns, to find that a 3-inch-diameter single -wall metal vent connector is not recommended. Moving to the next larger size single wall connector (4 inches), note that a 4-inch-diameter single -wall metal connector has a recommended minimum vent capacity of 91,000 Btu per hour and a recommended maximum vent capacity of 144,000 Btu per hour. The 80,000 Btu per hour fan -assisted appliance is outside this range, so the conclusion is that a single -wall metal vent connector can not be used to vent this appliance using 10 feet of lateral for the connector. However, if the 80,000 Btu per hour input appliance could be moved to within 5 feet of the vertical vent, then a 4-inch single -wall metal connector could be used to vent the appliance. Table 504.2(2) shows the acceptable range of vent capacities for a 4-inch vent with 5 feet of lateral to be between 72,000 Btu per hour and 157,000 Btu per hour. If the appliance cannot be moved closer to the vertical vent, then Type B vent could be used as the connector material. In this case, Table 504.2(1) shows that for a 30-foot-high vent with 10 feet of lateral, the acceptable range of vent capacities for a 4-inch-diameter vent attached to a fan -assisted appliance is between 37,000 Btu per hour and 150,000 Btu per hour. Example 3: Interpolating between table values. An installer has an 80,000 Btu per hour input appliance with a 4-inch-diameter draft hood outlet that needs to be vented into a 12-foot-high Type B vent. The vent connector has a 5-foot lateral length and is also Type B. Can this appliance be vented using a 4-inch-diameter vent? 2018 INTERNATIONAL FUEL GAS CODE ME (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No FLths[TAodomoo.mAt,Tgoodomo,o by anytlt Party oT ATmboemdm6A[vsd Mgle ass¢ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER RBPLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Solution: Table 504.2(1) is used in the case of an all Type B vent system. However,since there is no entry in Table 504.2(1) for a height of 12 feet, interpolation must be used. Read down the 4-inch diameter NAT Max column to the row associated with 10-foot height and 5-foot lateral to find the capacity value of 77,000 Btu per hour. Read further down to the 15-foot height, 5-foot lateral row to find the capacity value of 87,000 Btu per hour. The difference between the 15-foot height capacity value and the 10-foot height capacity value is 10,000 Btu per hour. The capacity for a 2 vent system with a 12-foot height is equal to the capacity for a 10-foot height plus / of the 5 2 difference between the 10-foot and 15-foot height values, or 77,000 + / (10,000) = 81,000 Btu 5 per hour. Therefore, a 4-inch-diameter vent can be used in the installation. EXAMPLES USING COMMON VENTING TABLES Example 4: Common venting two draft -hood -equipped appliances. A 35,000 Btu per hour water heater is to be common vented with a 150,000 Btu per hour furnace using a common vent with a total height of 30 feet. The connector rise is 2 feet for the water heater with a horizontal length of 4 feet. The connector rise for the furnace is 3 feet with a horizontal length of 8 feet. Assume single -wall metal connectors will be used with Type B vent. What size connectors and combined vent should be used in this installation? Solution: Table 504.3(2) should be used to size single -wall metal vent connectors attached to Type B vertical vents. In the vent connector capacity portion of Table 504.3(2), find the row associated with a30-foot vent height. For a 2-foot rise on the vent connector for the water heater, read the shaded columns for draft -hood -equipped appliances to find that a 3-inch-diameter vent connector has a capacity of 37,000 Btu per hour. Therefore, a 3-inch single -wall metal vent connector can be used with the water heater. For a draft -hood -equipped furnace with a 3-foot rise, read across the appropriate row to find that a 5-inch-diameter vent connector has a maximum capacity of 120,000 Btu per hour (which is too small for the furnace) and a 6-inch- diameter vent connector has a maximum vent capacity of 172,000 Btu per hour. Therefore, a 6- inch-diameter vent connector should be used with the 150,000 Btu per hour furnace. Since both vent connector horizontal lengths are less than the maximum lengths listed in Section 504.3.2, the table values can be used without adjustments. In the common vent capacity portion of Table 504.3(2), find the row associated with a 30- foot vent height and read over to the NAT + NAT portion of the 6-inch-diameter column to find a maximum combined capacity of 257,000 Btu per hour. Since the two appliances total only 185,000 Btu per hour, a 6-inch common vent can be used. 2018 INTERNATIONAL FUEL GAS CODE 285 (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Example 5a: Common venting a draft -hood -equipped water heater with a fan -assisted furnace into a Type B vent. In this case, a 35,000 Btu per hour input draft -hood -equipped water heater with a 4-inch- diameter draft hood outlet, 2 feet of connector rise, and 4 feet of horizontal length is to be common vented with a 100,000 Btu per hour fan -assisted furnace with a 4-inch-diameter flue collar, 3 feet of connector rise, and 6 feet of horizontal length. The common vent consists of a 30-foot height of Type B vent. What are the recommended vent diameters for each connector and the common vent? The installer would like to use a single -wall metal vent connector. Solution: [Table 504.3(2)]. Water Heater Vent Connector Diameter. Since the water heater vent connector horizontal length of 4 feet is less than the maximum value listed in Section504.3.2, the venting table values can be used without adjustments. Using the Vent Connector Capacity portion of Table 504.3(2), read down the Total Vent Height (/ /) column to 30 feet and read across the 2-foot Connector Rise (R) row to the first Btu per hour rating in the NAT Max column that is equal to or greater than the water heater input rating. The table shows that a 3-inch vent connector has a maximum input rating of 37,000 Btu per hour. Although this is greater than the water heater input rating, a 3-inch vent connector is prohibited by Section 504.3.21. A 4-inch vent connector has a maximum input rating of 67,000 Btu per hour and is equal to the draft hood outlet diameter. A 4- inch vent connector is selected. Since the water heater is equipped with a draft hood, there are no minimum input rating restrictions. Furnace Vent Connector Diameter. Using the Vent Connector Capacity portion of Table 504.3(2), read down the Total Vent Height (/ /) column to 30 feet and across the 3-foot Connector Rise (R) row. Since the furnace has a fan -assisted combustion system, find the first FAN Max column with a Btu per hour rating greater than the furnace input rating. The 4-inch vent connector has a maximum input rating of 119,000 Btu per hour and a minimum input ratingof 85,000 Btu per hour. The 100,000 Btu per hour furnace in this example falls within this range, so a 4-inch connector is adequate. Since the furnace vent connector horizontal length of 6 feet does not exceed the maximum value listed in Section 504.3.2, the venting table values can be used without adjustment. If the furnace had an input rating of 80,000 Btu per hour, then a Type B vent connector [see Table 504.3(1)] would be needed in order to meet the minimum capacity limit. Common Vent Diameter. The total input to the common vent is 135,000 Btu per hour. Using the Common Vent Capacity portion of Table 504.3(2), read down the Total Vent Height (/ /) column to 30 feet and across this row to find the smallest vent diameter in the FAN + NAT column that has a Btu per hour rating equal to or greater than 135,000 Btu per hour. The 4-inch common vent has a capacity of 132,000 Btu per hour and the 5-inch common vent has a capacity of 202,000 Btu per hour. Therefore, the 5-inch common vent should be used in this example. Summary. In this example, the installer can use a 4-inch diameter, single -wall metal vent connector for the water heater and a 4-inch-diameter, single -wall metal vent connector for the furnace. The common vent should be a 5-inch-diameter Type B vent. 2018 INTERNATIONAL FUEL GAS CODE (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No FLths[TAodomoo.mAt,Tgoodomo,o by anytlt Party oT ATmboemdm6A[vsd Mgle ass¢ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER RBPLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Example 5b: Common venting into a masonry chimney. In this case, the water heater and fan -assisted furnace of Example 5a are to be common vented into a clay tile -lined masonry chimney with a 30-foot height. The chimney is not exposed to the outdoors below the roof line. The internal dimensions of the clay tile liner are nominally 8 inches by 12 inches. Assuming the same vent connector heights, laterals, and materials found in Example 5a, what are the recommended vent connector diameters, and is this an acceptable installation? Solution: Table 504.3(4) is used to size common venting installations involving single -wall connectors into masonry chimneys. Water Heater Vent Connector Diameter.Using Table 504.3(4), Vent Connector Capacity, read down the Total Vent Height (/ /) column to 30 feet, and read across the 2-foot Connector Rise (R) row to the first Btu per hour rating in the NAT Max column that is equal to or greater than the water heater input rating. The table shows that a 3-inch vent connector has a maximum input of only 31,000 Btu per hour while a 4-inch vent connector has a maximum input of 57,000 Btu per hour. A 4-inch vent connector must therefore be used. Furnace Vent Connector Diameter. Using the Vent Connector Capacity portion of Table 504.3(4), read down the Total Vent Height (/ /) column to 30 feet and across the 3-foot Connector Rise (R) row. Since the furnace has a fan -assisted combustion system, find the first FAN Max column with a Btu per hour rating greater than the furnace input rating. The 4-inch vent connector has a maximum input rating of 127,000 Btu per hour and a minimum input rating of 95,000 Btu per hour. The 100,000 Btu per hour furnace in this example falls within this range, so a 4-inch connector is adequate. Masonry Chimney. From Table B-1, the equivalent area for a nominal liner size of 8 inches by 12 inches is 63.6 square inches. Using Table 504.3(4), Common Vent Capacity, read down the FAN + NAT column under the Minimum Internal Area of Chimney value of 63 to the row for 30-foot height to find a capacity value of 739,000 Btu per hour. The combined input rating of the furnace and water heater, 135,000 Btu per hour, is less than the table value, so this is an acceptable installation. Section 504.3.17 requires the common vent area to be not greater than seven times the smallest listed appliance categorized vent area, flue collar area, or draft hood outlet area. Both appliances in this installation have 4-inch-diameter outlets. From Table B-1, the equivalent area for an inside diameter of 4 inches is 12.2 square inches. Seven times 12.2 equals 85.4, which is greater than 63.6, so this configuration is acceptable. Example 5c: Common venting into an exterior masonry chimney. In this case, the water heater and fan -assisted furnace of Examples 5a and 5b are to be common vented into an exterior masonry chimney. The chimney height, clay tile liner dimensions, and vent connector heights and laterals are the same as in Example 5b. This system is being installed in Charlotte, North Carolina. Does this exterior masonry chimney need to be relined? If so, what corrugated metallic liner size is recommended? What vent connector diameters are recommended? 2018 INTERNATIONAL FUEL GAS CODE 287 (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER RBPLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Solution: In accordance with Section 504.3.20, Type B vent connectors are required to be used with exterior masonry chimneys. Use Tables 504.3(7a), (7b) to size FAN+NAT common venting installations involving Type-B double wall connectors into exterior masonry chimneys. The local 99-percent winter design temperature needed to use Table 504.3(7b) can be found in the ASHRAE Handbook of Fundamentals. For Charlotte, North Carolina, this design temperature is 19°F. Chimney Liner Requirement. As in Example 5b, use the 63 square inch Internal Area columns for this size clay tile liner. Read down the 63 square inch column of Table 504.3(7a) to the 30-foot height row to find that the combined appliance maximum input is 747,000 Btu per hour. The combined input rating of the appliances in this installation, 135,000 Btu per hour, is less than the maximum value, so this criterion is satisfied. Table 504.3(7b), at a 19°F design temperature, and at the same vent height and internal area used above, shows that the minimum allowable input rating of a space -heating appliance is 470,000 Btu per hour. The furnace input rating of 100,000 Btu per hour is less than this minimum value. So this criterion is not satisfied, and an alternative venting design needs to be used, such as a Type B vent shown in Example 5a or a listed chimney liner system shown in the remainder of the example. In accordance with Section 504.3.19, Table 504.3(1) or 504.3(2) is used for sizing corrugated metallic liners in masonry chimneys, with the maximum common vent capacities reduced by 20 percent. This example will be continued assuming Type B vent connectors. Water Heater Vent Connector Diameter. Using Table 504.3(1), Vent Connector Capacity, read down the Total Vent Height (H) column to 30 feet, and read across the 2-foot Connector Rise (R) row to the first Btu/h rating in the NAT Max column that is equal to or greater than the water heater input rating. The table shows that a 3-inch vent connector has a maximum capacity of 39,000 Btu/h. Although this rating is greater than the water heater input rating, a 3-inch vent connector is prohibited by Section 504.3.21. A 4-inch vent connector has a maximum input rating of 70,000 Btu/h and is equal to the draft hood outlet diameter. A 4-inch vent connector is selected. Furnace Vent Connector Diameter. Using Table 504.3(1), Vent Connector Capacity, read down the Vent Height (H) column to 30 feet, and read across the 3-foot Connector Rise (R) row to the first Btu per hour rating in the FAN Max column that is equal to or greater than the furnace input rating. The 100,000 Btu per hour furnace in this example falls within this range, so a 4-inch connector is adequate. Chimney Liner Diameter. The total input to the common vent is 135,000 Btu per hour. Using the Common Vent Capacity Portion of Table 504.3(1), read down the Vent Height (H) column to 30 feet and across this row to find the smallest vent diameter in the FAN+NAT column that has a Btu per hour rating greater than 135,000 Btu per hour. The 4-inch common vent has a capacity of 138,000 Btu per hour. Reducing the maximum capacity by 20 percent (Section 504.3.19) results in a maximum capacity for a 4-inch corrugated liner of 110,000 Btu per hour, less than the total input of 135,000 Btu per hour. So a larger liner is needed. The 5-inch common vent capacity listed in Table 504.3(1) is 210,000 Btu per hour, and after reducing by 20 percent is 168,000 Btu per hour. Therefore, a 5-inch corrugated metal liner should be used in this example. 2018 INTERNATIONAL FUEL GAS CODER 288 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.

Appendix D provides procedures for testing and inspecting existing gas appliance installations for safe operation. DA General. The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in a safe condition for continued use. Where a gas supplier performs an inspection, their written procedures should be followed. D.1.1 Application. This procedure is intended for existing residential installations of a furnace, boiler, room heater, water heater, cooking appliance, fireplace appliance and clothes dryer. This procedure should be performed prior to any attempt to modify the appliance installation or building envelope. D.1.2 Weatherization P-Rrograms. Before a building envelope is to be modified as part of a weatherization program, the existing appliance installation should be inspected in accordance with these procedures. After all unsafe conditions are repaired, and immediately after the weatherization is complete, the appliance inspections in D.5.2 are to be repeated. D.1.3 Inspection P-Rrocedure. The safety of the building occupant and inspector are to be determined as the first step as described in D.2. Only after the ambient environment is found to be safe should inspections of gas piping and appliances be undertaken. It is recommended that all inspections described in D.3, DA and D.6, where the appliance is in the off mode, be completed and any unsafe conditions repaired or corrected before continuing with inspections of an operating appliance described in D.5 and D.6. D.1.4 Manufacturer instructions.

AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER D.1.5 Instruments. The inspection procedures include measuring for fuel gas and carbon monoxide (CO) and will require the use of a combustible gas detector (CGD) and a CO detector. It is recommended that both types of detectors be listed. Prior to any inspection, the detectors should be calibrated or tested in accordance with the manufacturer's instructions. In addition, it is recommended that the detectors have the following minimum specifications. (1) Gas Detector: The CGD should be capable of indicating the presence of the type of fuel gas for which it is to be used (e.g. natural gas or propane). The combustible gas detector should be capable of the following: a. PPM: Numeric display with a parts per million (ppm) scale from 1 ppm to 900 ppm in 1 ppm increments. b. LEL: Numeric display with a percent lower explosive limit (% LEL) scale from 0 percent to 100 percent in 1 percent increments. c. Audio: An audio sound feature to locate leaks. (2) CO Detector: The CO detector should be capable of the following functions and have a numeric display scale as follows: PPM: For measuring ambient room and appliance emissions a display scale in parts per million (ppm) from 0 to 1,000 ppm in 1 ppm increments. b. Alarm: A sound alarm function where hazardous levels of ambient CO is found (see D.2 for alarm levels) c. Air Free: Capable of converting CO measurements to an air free level in ppm. Where a CO detector is used without an air free conversion function, the CO air free can be calculated in accordance with footnote 3 in Table D.6. D.2 Occupant and tinspector 4.safety. Prior to entering a building, the inspector should have both a combustible gas detector (CGD) and CO detector turned on, calibrated, and operating. Immediately upon entering the building, a sample of the ambient atmosphere should be taken. Based on CGD and CO detector readings, the inspector should take the following actions: (1) The CO detector indicates a carbon monoxide level of 70 ppm or greater The inspector should immediately notify the occupant of the need for themselves and any building occupant to evacuate; the inspector shall immediately evacuate and call 911. 1 (2) Where the CO detector indicates a reading between 30 ppm and 70 ppm . The inspector should advise the occupant that high CO levels have been found and recommend that all possible sources of CO should be turned off immediately and windows and doors opened. Where it appears that the source of CO is a permanently installed appliance, advise the occupant to keep the appliance off and have the appliance serviced by a qualified servicing agent. 2018 INTERNATIONAL FUEL GAS CODE 307 CopyngbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,d—od om).(Qty of IFnmd—od)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,—t to LET Ag,,—®'^Rt, ICC No fwN¢[TAodomoo.m AtO, Tgoodomo- by anytlt Party oT ATmboem-thowd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT. AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 1 (3) Where CO detector indicates CO below 30 ppm the inspection can continue. (4) The CGD indicates a combustible gas level of 20% LEL or greater. The inspector should immediately notify the occupant of the need for themselves and any building occupant to evacuate; the inspector shall immediately evacuate and call 911. (5) The CGD indicates a combustible gas level below 20% LEL, the inspection can continue. If during the inspection process it is determined a condition exists that could result in unsafe appliance operation, shut off the appliance and advise the owner of the unsafe condition. Where a gas leak is found that could result in an unsafe condition, advise the ownerof the unsafe condition and call the gas supplier to turn off the gas supply. The inspector should not continue a safety inspection on an operating appliance, venting system, and piping system until repairs have been made. D.3 Gas RRiping and Gconnection linspections. (1) Leak Checks. Conduct a test for gas leakage using either a non -corrosive leak detection solution or a CGD confirmed with a leak detection solution. The preferred method for leak checking is by use of gas leak detection solution applied to all joints. This method provides a reliable visual indication of significant leaks. The use of a CGD in its audio sensing mode can quickly locate suspect leaks but can be overly sensitive indicating insignificant and false leaks. All suspect leaks found through the use of a CGD should be confirmed using a leak detection solution. Where gas leakage is confirmed, the owner should be notified that repairs must be made. The inspection should include the following components: a. All gas piping fittings located within the appliance space. b. Appliance connector fittings. c. Appliance gas valve/regulator housing and connections. (2) Appliance Connector. Verify that the appliance connection type is compliant with Section 411 of the International Fuel Gas Code.lnspect flexible appliance connections to determine if they are free of cracks, corrosion and signs of damage. Verify that there are no uncoated brass connectors. Where connectors are determined to be unsafe or where an uncoated brass connector is found,the appliance shutoff valve should be placed in the off position and the owner notified that the connector must be replaced. (3) Piping Support. Inspect piping to determine that it is adequately supported, that there is no undue stress on the piping, and if there are any improperly capped pipe openings. (4) Bonding. Verify that the electrical bonding of gas piping is compliant with Section 310 of the International Fuel Gas Code. 2018 INTERNATIONAL FUEL GAS CODE M (ATFIgbtOO?.o17 ICC ALL RIGHTS RESERVED Awned by HDO,, Van Dme(Rv dme Oo,dv od om).(Qty of PnmdNmod)Odo,Nomb,,x1ooe1vmv 01 JM 15. xm.o oc ss AM (PET) Mt,b,mt to LET Ag,, ^®'^Rt, ICC No fwN¢[TAodomo,,m AtO, Tgoodomo- by anytlt Party oT ATmboemdm6A[vsd Mglo—ody oTyncg and Nyodwg TARISd ANY VNAVTHO RIVER REICLA VCIION OR DISIRIBITTO N IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT.
