2027 International Fuel Gas Code - SOFT COVER

Now Available!

The 2027 International Fuel Gas Code® (IFGC®) sets minimum requirements for fuel-gas piping, appliances, gaseous hydrogen systems, and accessories. Its prescriptive and performance provisions support safe installation and operation throughout a building’s life.

The 2027 edition addresses appliances using natural gas blended with hydrogen, clarifies gas-demand calculations and permitted return-air locations, and updates pressure-testing requirements and clearance reductions. It also adds marginal markings and QR codes to help identify changes, online relocation tables, full-color digital images, and alternative text for figures.
