Fuel-gas installations require careful attention to piping, appliance connections, combustion air, and exhaust venting. The International Fuel Gas Code (IFGC) 2024 Book, published by the International Code Council (ICC), provides code provisions for professionals who work with fuel-gas distribution systems and gas-fired appliances. Identified by ISBN 9781959851790, this paperback edition is a technical reference for researching installation requirements, reviewing project specifications, and understanding the provisions applicable to fuel-gas systems.
A significant part of the 2024 International Fuel Gas Code focuses on gas piping installations. Chapter 4 addresses piping materials, sizing, connections, pressure testing, and related installation considerations. These provisions are relevant when evaluating gas distribution layouts or researching how piping systems should be addressed within the Code. Chapter 3 covers general requirements, including appliance locations, access, clearances, protection of building components, and combustion air. Together, these subjects help readers examine the relationship between gas-fired equipment, its installation environment, and the systems needed for operation.
Venting is another important area covered by the IFGC. Chapter 5 addresses chimneys, vents, and the removal of combustion products from appliances. Chapter 6 focuses on specific appliances, providing requirements associated with different types of gas-fired equipment. The Code also addresses gaseous hydrogen systems in Chapter 7, alongside referenced standards in Chapter 8. This coverage gives readers a structured way to investigate fuel-gas topics ranging from conventional appliance installations to specialized systems that require particular technical considerations.
The publication includes appendices that extend its practical reference value. Appendix A covers gas-piping sizing and capacities, while Appendix B addresses venting-system sizing for specified appliance and vent configurations. Appendix C provides a recommended procedure for inspecting existing appliance installations, and Appendix D addresses boards of appeals. These resources can help professionals locate supporting information when researching pipe capacity, vent design, or the assessment of an existing installation.
Gas fitters, plumbing and mechanical contractors, HVAC technicians, mechanical engineers, architects, building officials, inspectors, and plan reviewers may use the 2024 International Fuel Gas Code for technical consultation and project research. Apprentices, instructors, and students can also use it to study fuel-gas terminology, piping principles, appliance venting, and code organization. Its focus is specifically on fuel-gas systems, making it distinct from broader mechanical or plumbing references that address additional building systems.
The 2024 edition also features a revised presentation across the International Codes, including a single-column layout, updated typography, improved table formatting, and QR codes that identify sections with technical changes from the previous code cycle. These features can help readers navigate the printed text and locate information about revisions. For projects involving fuel-gas piping, gas-fired appliances, combustion air, or venting, this edition offers a dedicated reference for consulting the applicable provisions.
If your work requires the International Fuel Gas Code (IFGC) 2024 edition, this ICC paperback brings the Code’s principal fuel-gas topics and supporting appendices together in one volume. Before using it for an active project, confirm the edition and amendments adopted by the relevant jurisdiction.
