All rights reserved.PRINTED IN THE U.S.A.2018 INTERNATIONAL FUEL GAS CODEiiiPREFACEIntroductionThe Inter
7、national Fuel Gas Code(IFGC) establishes minimum requirements for fuel gas systemsand gas-fired appliances using prescriptive and performance-related provisions. It is founded onbroad-based principles that make possible the use of new materials and new fuel gas system andappliance designs. This 2018
8、 edition is fully compatible with all of the International Codes(I-Codes) published by the International Code Council(ICC), including the International BuildingCode, International Energy Conservation Code, International Existing Building Code, Interna-tional Fire Code, International Green Constructi
9、on Code, International Mechanical Code, Interna-tional Plumbing Code, International Private Sewage Disposal Code, International PropertyMaintenance Code, International Residential Code, International Swimming Pool and Spa Code,International Wildland-Urban Interface Code, International Zoning Codeand
10、 International CodeCouncil Performance Code.The I-Codes, including this International Fuel Gas Code, are used in a variety of ways in both thepublic and private sectors. Most industry professionals are familiar with the I-Codes as the basis oflaws and regulations in communities across the U.S. and i
11、n other countries. However, the impact ofthe codes extends well beyond the regulatory arena, as they are used in a variety of nonregulatorysettings, including: Voluntary compliance programs such as those promoting sustainability, energy efficiencyand disaster resistance. The insurance industry, to e
12、stimate and manage risk, and as a tool in underwriting and ratedecisions. Certification and credentialing of individuals involved in the fields of building design, con-struction and safety. Certification of building and construction-related products. U.S. federal agencies, to guide construction in a
13、n array of government-owned properties. Facilities management. “Best practices” benchmarks for designers and builders, including those who are engaged inprojects in jurisdictions that do not have a formal regulatory system or a governmentalenforcement mechanism. College, university and professional
14、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 pro-fessionals on a regular basis. It provides an international forum for discussion and deliberationabout building d
15、esign, construction methods, safety, performance requirements, technologicaladvances and innovative products.DevelopmentThis 2018 edition presents the code as originally issued, with changes reflected in the 2003 through2015 editions and further changes approved by the ICC Code Development Process t
16、hrough 2017and standard revisions correlated with ANSI Z223.1-2018. A new edition such as this is promulgatedevery 3 years.This code is founded on principles intended to establish provisions consistent with the scope of afuel gas code that adequately protects public health, safety and welfare; provi
17、sions that do notunnecessarily 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 par-ticular types or classes of materials, products or methods of construction.iv 2018 I
18、NTERNATIONAL FUEL GAS CODEFormatThe 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., Sec
19、tion 101). The sec-tions 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 islocated under an “IFGC” main section.MaintenanceThe International Fuel Gas Code is kept
20、up to date through the review of proposed changes submit-ted by code enforcement officials, industry representatives, design professionals and other inter-ested parties. Proposed changes are carefully considered through an open code developmentprocess in which all interested and affected parties may
21、 participate.The ICC Code Development Process reflects principles of openness, transparency, balance, dueprocess and consensus, the principles embodied in OMB Circular A-119, which governs the federalgovernments use of private-sector standards. The ICC process is open to anyone; there is no cost top
22、articipate, and people can participate without travel cost through the ICCs 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 whenrequired for
23、health and safety reasons.In order to ensure that organizations with a direct and material interest in the codes have a voicein the process, the ICC has developed partnerships with key industry segments that support theICCs important public safety mission. Some code development committee members wer
24、e nomi-nated by the following industry partners and approved by the ICC Board: American Gas Association (AGA) American Institute of Architects (AIA)The code development committees evaluate and make recommendations regarding proposedchanges to the codes. Their recommendations are then subject to publ
25、ic comment and council-widevotes. The ICCs governmental memberspublic safety officials who have no financial or businessinterest in the outcomecast the final votes on proposed changes.The contents of this work are subject to change through the code development cycles and by anygovernmental entity th
26、at enacts the code into law. For more information regarding the code devel-opment process, contact the Codes and Standards Development Department of the InternationalCode Council.While the I-Code development procedure is thorough and comprehensive, the ICC, its membersand those participating in the
27、development of the codes disclaim any liability resulting from thepublication or use of the I-Codes, or from compliance or noncompliance with their provisions. TheICC does not have the power or authority to police or enforce compliance with the contents of thiscode.Code Development Committee Respons
28、ibilities(Letter Designations in Front of Section Numbers)In each code development cycle, proposed changes to the code are considered at the CommitteeAction Hearings by the International Fuel Gas Code Development Committee, whose action consti-tutes a recommendation to the voting membership for fina
29、l action on the proposed change. Pro-posed changes to a code section that has a number beginning with a letter in brackets areconsidered by a different code development committee. For example, proposed changes to codesections that have BS in front of them (e.g., BS 302.1) are considered by the IBCSt
30、ructural CodeDevelopment Committee at the Committee Action Hearings.2018 INTERNATIONAL FUEL GAS CODEvThe content of sections in this code that begin with letter designations is maintained by othercode development committees in accordance with the following:A = Administrative Code Development Committ

38、them will be heard by the respective committee responsible for such code sections. Because differ-ent committees hold Committee Action Hearings in different years, it is possible that some propos-als for this code will be heard by committees in both 2018 (Group A) and the 2019 (Group B) codedevelopm
39、ent cycles.For instance, every section of Chapter 1 of this code is designated as the responsibility of theAdministrative 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 propos
40、-als for Chapter 1 of this code and proposals for Chapter 1 of all I-Codes except the InternationalEnergy Conservation Code, International Residential Code and International Green ConstructionCode. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Adminis-trative C
41、ode Development Committee for consideration in 2019.It is very important that anyone submitting code change proposals understands which codedevelopment committee is responsible for the section of the code that is the subject of the codechange proposal. For further information on the code development
42、 committee responsibilities,please visit the ICC website at www.iccsafe.org/scoping.Marginal MarkingsSolid vertical lines in the margins within the body of the code indicate a technical change from therequirements of the 2015 edition. Deletion indicators in the form of an arrow ( ) are provided inth
43、e margin where an entire section, paragraph, exception or table has been deleted or an item in alist of items or a table has been deleted.Coordination of the International CodesThe coordination of technical provisions is one of the strengths of the ICC family of model codes.The codes can be used as
44、a complete set of complementary documents, which will provide userswith full integration and coordination of technical provisions. Individual codes can also be used insubsets or as stand-alone documents. To make sure that each individual code is as complete as pos-sible, some technical provisions th
45、at are relevant to more than one subject area are duplicated insome of the model codes. This allows users maximum flexibility in their application of the I-Codes.Italicized TermsWords and terms defined in Chapter 2, Definitions, are italicized where they appear in code text andthe Chapter 2 definiti
46、on applies. Where such words and terms are not italicized, common-use defi-nitions apply. The words and terms selected have code-specific definitions that the user should readcarefully to facilitate better understanding of the code.a1722018 INTERNATIONAL FUEL GAS CODEviiAdoptionThe International Cod
