Internationally, code officials recognize the need for a modern, up-to-date fuel gas code addressing the design and installation of fuel gas systems and gas-fired appliances through requirements emphasizing performance. The International Fuel Gas Code®, in this 2015 edition, is designed to meet these needs through model code regulations that safeguard the public health and safety in all communities, 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. It is founded on broad-based principles that make possible the use of new materials and new fuel gas system and appliance 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 Building Code®, International 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 Property Maintenance Code®, International Residential Code®, International Swimming Pool and Spa Code™, International Wildland-Urban Interface Code® and International Zoning Code®.
The International Fuel Gas Code provisions provide many benefits, among which is the model code development process that offers an international forum for fuel gas technology professionals to discuss performance and prescriptive code requirements. This forum provides an excellent arena to debate proposed revisions. This model code also encourages international consistency in the application of provisions.
The first edition of the International Fuel Gas Code (1997) was the culmination of an effort initiated in 1996 by a development committee appointed by ICC and consisting of representatives of the three statutory members of the International Code Council at that time, including: Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI) and the gas industry. The intent was to draft a comprehensive set of regulations for fuel gas systems and gas-fired appliances consistent with and inclusive of the scope of the existing mechanical, plumbing and gas codes. Technical content of the latest model codes promulgated by BOCA, ICBO, SBCCI and ICC and the National Fuel Gas Code (ANSI Z223.1) was utilized as the basis for the development. This 2015 edition presents the code as originally issued, with changes reflected in subsequent editions through 2012, and with code changes approved through the ICC Code Development Process through 2013 and standard revisions 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 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.
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.
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 International Fuel Gas Code is designed for adoption and use 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 ICC codes and ICC 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 firstname.lastname@example.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.
The International Fuel Gas Code is kept up to date through the review of proposed changes submitted by code enforcing 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 contents of this work are subject to change through both the Code Development Cycles and the governmental body 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 development procedure of the International Fuel Gas Code ensures the highest degree of care, the ICC, its members and those participating in the development of this code do not accept any liability resulting from compliance or noncompliance with the provisions because the ICC does not have the power or authority to police or enforce compliance with the contents of this code. Only the governmental body that enacts the code into law has such authority.
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 code development 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.|
For the development of the 2018 edition of the I-Codes, there will be three groups of code development committees and they will meet in separate years. Note that these are tentative groupings.
|Group A Codes (Heard in 2015, Code Change Proposals Deadline: January 12, 2015)||Group B Codes (Heard in 2016, Code Change Proposals Deadline: January 11, 2016)||Group C Codes (Heard in 2017, Code Change Proposals Deadline: January 11, 2017)|
|International Building Code– Fire Safety (Chapters 7, 8, 9, 14, 26)– Means of Egress(Chapters 10, 11, Appendix E)– General (Chapters 2-6, 12, 27-33,Appendices A, B, C, D, K)||Administrative Provisions (Chapter 1 of all codes except IRC and IECC, administrative updates to currently referenced standards, and designated definitions)||International Green Construction Code|
|International Fuel Gas Code||International Building Code– Structural(Chapters 15-25, Appendices F, G,H, I, J, L, M)|

Note: 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 of them will be heard by the respective committee responsible for such code sections. Because different committees hold code development hearings in different years, it is possible that some proposals for this code will be heard by committees in both 2015 (Group A) and the 2016 (Group B) code development cycles.
For instance, every section of Chapter 1 of this code is designated as the responsibility of the Administrative Code Development Committee, and that committee is part of the Group B portion of the hearings. This committee will hold its code development hearings in 2016 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 ICC Performance Code. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Administrative Code Development Committee for consideration in 2016.
It is very important that anyone submitting code change proposals understand 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.
