6、iiPREFACEIntroductionInternationally, code officials recognize the need for a modern, up-to-date fuel gas code addressingthe design and installation of fuel gas systems and gas-fired appliances through requirementsemphasizing performance. The International Fuel Gas Code, in this 2015 edition, is des
7、igned tomeet these needs through model code regulations that safeguard the public health and safety in allcommunities, large and small.This comprehensive fuel gas code establishes minimum regulations for fuel gas systems and gas-fired appliances using prescriptive and performance-related provisions.
8、 It is founded on broad-based principles that make possible the use of new materials and new fuel gas system and appli-ance designs. This 2015 edition is fully compatible with all of the International Codes(I-Codes)published by the International Code Council (ICC), including the International Buildi
9、ng Code, Inter-national Energy Conservation Code, International Existing Building Code, International Fire Code,International Green Construction Code, International Mechanical Code, ICC Performance Code,International Plumbing Code, International Private Sewage Disposal Code, International PropertyMa
10、intenance Code, International Residential Code, International Swimming Pool and Spa Code,International Wildland-Urban Interface Codeand International Zoning Code.The International Fuel Gas Code provisions provide many benefits, among which is the modelcode development process that offers an internat
11、ional forum for fuel gas technology professionalsto discuss performance and prescriptive code requirements. This forum provides an excellent arenato debate proposed revisions. This model code also encourages international consistency in theapplication of provisions.DevelopmentThe first edition of th
12、e International Fuel Gas Code (1997) was the culmination of an effort initiatedin 1996 by a development committee appointed by ICC and consisting of representatives of thethree statutory members of the International Code Council at that time, including: Building Officialsand Code Administrators Inte
13、rnational, Inc. (BOCA), International Conference of Building Officials(ICBO) and Southern Building Code Congress International (SBCCI) and the gas industry. The intentwas to draft a comprehensive set of regulations for fuel gas systems and gas-fired appliances consis-tent with and inclusive of the s
14、cope of the existing mechanical, plumbing and gas codes. Technicalcontent of the latest model codes promulgated by BOCA, ICBO, SBCCI and ICC and the National FuelGas Code (ANSI Z223.1) was utilized as the basis for the development. This 2015 edition presentsthe code as originally issued, with change
15、s reflected in subsequent editions through 2012, and withcode changes approved through the ICC Code Development Process through 2013 and standardrevisions correlated with ANSI Z223.1-2015. A new edition such as this is promulgated every 3 years.This code is founded on principles intended to establis
16、h provisions consistent with the scope of afuel gas code that adequately protects public health, safety and welfare; provisions 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 n
17、ot give preferential treatment to par-ticular types or classes of materials, products or methods of construction.FormatThe 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 t
18、hat are “code”are designated by the acronym “IFGC” next to the main section number (e.g., Section 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
19、it islocated under an “IFGC” main section.iv 2015 INTERNATIONAL FUEL GAS CODEAdoptionThe International Code Council maintains a copyright in all of its codes and standards. Maintainingcopyright allows the ICC to fund its mission through sales of books, in both print and electronic for-mats. The Inte
20、rnational Fuel Gas Code is designed for adoption and use by jurisdictions that recog-nize and acknowledge the ICCs copyright in the code, and further acknowledge the substantialshared value of the public/private partnership for code development between jurisdictions and theICC.The ICC also recognize
21、s the need for jurisdictions to make laws available to the public. AllICC codes and ICC standards, along with the laws of many jurisdictions, are available for freein a nondownloadable form on the ICCs website. Jurisdictions should contact the ICC atadoptionsiccsafe.org to learn how to adopt and dis
22、tribute laws based on the InternationalFuel Gas Code in a manner that provides necessary access, while maintaining the ICCs copy-right.MaintenanceThe International Fuel Gas Code is kept up to date through the review of proposed changes submit-ted by code enforcing officials, industry representatives
23、, design professionals and other interestedparties. Proposed changes are carefully considered through an open code development process inwhich all interested and affected parties may participate.The contents of this work are subject to change through both the Code Development Cycles andthe governmen
24、tal body that enacts the code into law. For more information regarding the codedevelopment process, contact the Codes and Standards Development Department of the Interna-tional Code Council.While the development procedure of the International Fuel Gas Code ensures the highest degreeof care, the ICC,
25、 its members and those participating in the development of this code do not acceptany liability resulting from compliance or noncompliance with the provisions because the ICC doesnot have the power or authority to police or enforce compliance with the contents of this code.Only the governmental body
26、 that enacts the code into law has such authority.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 CommitteeAction Hearings by the International Fuel Gas Code Development Com
27、mittee, whose action consti-tutes 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 con-sidered by a different code development committee. For example, proposed changes to cod
28、e sec-tions that have BS in front of them (e.g., BS 302.1) are considered by the IBC Structural CodeDevelopment Committee at the code development hearings.The content of sections in this code that begin with letter designations is maintained by othercode development committees in accordance with the
29、 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
30、 Committee; andFG = International Mechanical Code Development Committee.2015 INTERNATIONAL FUEL GAS CODEvFor the development of the 2018 edition of the I-Codes, there will be three groups of code devel-opment committees and they will meet in separate years. Note that these are tentative groupings.No
31、te: Proposed changes to the ICC Performance Code will be heard by the code development committee noted in brackets in the text of the code.Code change proposals submitted for code sections that have a letter designation in front ofthem will be heard by the respective committee responsible for such c
32、ode sections. Because differ-ent committees hold code development hearings in different years, it is possible that some propos-als for this code will be heard by committees in both 2015 (Group A) and the 2016 (Group B) codedevelopment cycles.For instance, every section of Chapter 1 of this code is d
33、esignated as the responsibility of theAdministrative Code Development Committee, and that committee is part of the Group B portion ofthe hearings. This committee will hold its code development hearings in 2016 to consider all codechange proposals for Chapter 1 of this code and proposals for Chapter
34、1 of all I-Codes except theInternational Energy Conservation Code, International Residential Code and ICC Performance Code.Therefore, any proposals received for Chapter 1 of this code will be assigned to the AdministrativeCode Development Committee for consideration in 2016.It is very important that
35、 anyone submitting code change proposals understand which code devel-opment committee is responsible for the section of the code that is the subject of the code changeproposal.

44、 LOCATIONNone Nonea1722015 INTERNATIONAL FUEL GAS CODEviiEFFECTIVE USE OF THE INTERNATIONAL FUEL GAS CODEThe IFGC is a model code that regulates the design and installation of fuel gas distribution pipingand systems, appliances, appliance venting systems, combustion air provisions, gaseous hydrogens
45、ystems and motor vehicle gaseous-fuel-dispensing stations. The definition of fuel gas includes nat-ural, 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 lifeand property from the pote
46、ntial dangers associated with the storage, distribution and usage of fuelgases and the byproducts of combustion of such fuels. The code also protects the personnel thatinstall, maintain, service and replace the systems and appliances addressed by this code.With the exception of Section 401.1.1, the
47、IFGC does not address utility-owned piping and equip-ment (i.e., anything upstream of the point of delivery). See the definition of “Point of delivery” andSection 501.8 for other code coverage exemptions.The IFGC is primarily a specification-oriented (prescriptive) code with some performance-ori-ent
48、ed text. For example, Section 503.3.1 is a performance statement, but Chapter 5 contains pre-scriptive 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. TheIRC is referenced for coverage of one- an
49、d two-family dwellings and townhouses; however, ineffect, the IFGC provisions are still applicable because the fuel gas chapter in the IRC (Chapter 24) iscomposed 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 atpressures in excess of 125 psig for natural gas and 20 psig for LP-gas (note exception in Secti
