IFGC 2018 – International Fuel Gas Code
The 2018 International Fuel Gas Code is a practical technical reference for professionals responsible for designing, installing, inspecting, maintaining, or approving fuel-gas systems and gas-fired appliances. Published by the International Code Council, it establishes minimum requirements intended to support safe gas distribution and appliance operation.
The code addresses natural gas, liquefied petroleum gas, manufactured gas, and mixtures of these gases. Major subjects include appliance installation, combustion air, gas-piping materials and sizing, pressure regulators, appliance connections, overpressure protection, chimneys, vents, venting systems, specific gas-fired appliances, and gaseous hydrogen systems. It also contains procedures related to the safety inspection of existing appliance installations.
The 2018 edition includes several notable updates. It recognizes arc-resistant corrugated stainless-steel tubing products, permits Schedule 10 steel pipe under specified conditions, clarifies access to appliance shutoff valves behind movable appliances, introduces labeling requirements for plastic vent piping, and revises certain direct-vent terminal clearances.
This book is valuable for fuel-gas contractors, HVAC professionals, mechanical engineers, architects, building inspectors, plans examiners, code officials, facility managers, instructors, apprentices, and construction students. It can assist with system design, permit preparation, piping calculations, appliance installation, plan review, inspection work, troubleshooting, and examination study where the 2018 IFGC is specified.
The chapter-based arrangement helps users move directly to the relevant system or appliance requirement. This makes the book useful as an office, classroom, workshop, or jobsite reference.
Code adoption and local amendments differ by jurisdiction. Buyers should confirm that the 2018 edition applies to their project, employer, course, licensing examination, or local authority.
Order one copy for professional or educational use, or request bulk pricing for contractors, engineering firms, building departments, colleges, training centers, libraries, and resellers.
