2018 International Fuel Gas Code (International Code Council Series) 1st Edition

Comprehensive Guide to Fuel Gas Systems and Gas-Fired Appliance Installation

This updated code provides detailed prescriptive and performance requirements for the design and installation of fuel gas systems and gas-fired appliances. Key updates include:

• Arc-Resistant CSST Recognition: A new section addresses the inclusion of arc-resistant corrugated stainless steel tubing.
• Expanded Pipe Options: Schedule 10 steel pipe is now permitted, offering a lighter alternative to Schedule 40. Joints can be welded, brazed, flanged, or assembled with press-connect fittings, though threading is not allowed for Schedule 10 pipes.
• Appliance Shutoff Valve Accessibility: Clarifies that shutoff valves behind movable appliances, like ranges and dryers, meet access requirements.
• Plastic Vent Pipe Standards: Requires vent pipes to be labeled according to manufacturer-specific material standards or listed to UL1738.
• Revised Vent Terminal Clearances: Updates the clearances between direct-vent appliance vent terminals and building openings to improve safety against combustion product entry.

This edition ensures compliance with modern standards and enhances the safety and efficiency of gas system installations.
