IMC 2021 and IFGC 2021 Set: International Mechanical and Fuel Gas Codes (ICC)

2021 International Mechanical Code and International Fuel Gas Code set

This two-book set pairs the 2021 International Mechanical Code (IMC) with the 2021 International Fuel Gas Code (IFGC), both published by the International Code Council. Between them they cover HVAC, ventilation and exhaust systems as well as gas piping and gas-fired appliances.

Mechanical contractors and inspectors usually need both books, because gas appliance installation and venting sit in the IFGC while the rest of the mechanical system sits in the IMC.

What is in this set

• 2021 International Mechanical Code (IMC): Minimum regulations for HVAC, ventilation, exhaust and other mechanical systems. The 2021 edition sets a 3-foot clearance from dryer exhaust terminals to building openings and allows 30 percent less ventilation for balanced systems.
• 2021 International Fuel Gas Code (IFGC): Design and installation of fuel gas systems and gas-fired appliances. The 2021 edition accepts press-connect joints for indoor high pressure piping over 5 psi and bars commercial cooking appliances from dwelling units.

Who this set is for

HVAC and mechanical contractors, gas fitters, mechanical engineers, plans examiners and mechanical inspectors working where the 2021 I-Codes are enforced. It also suits candidates for mechanical licensing exams that reference the 2021 IMC and IFGC.

Questions buyers ask

Why buy the IMC and IFGC together?

The IMC covers mechanical systems while the IFGC covers fuel gas piping and gas appliances. Most HVAC work touches both, so contractors and inspectors keep them side by side.

Which editions are in this set?

Both books are the 2021 editions: IMC ISBN 9781609839642 and IFGC ISBN 9781609839666.

What changed for dryer exhaust in the 2021 IMC?

Clothes dryer exhaust terminals must be at least 3 feet from any opening into the building.

Are press-connect fittings allowed on high pressure gas piping?

The 2021 IFGC accepts press-connect joints for indoor high pressure applications over 5 psi.
