Ensuring Safe Gas Systems - A Guide to the IFGC

The International Fuel Gas Code (IFGC) sets the minimum standards for designing and installing safe and efficient fuel gas systems and appliances in buildings. Adopted by various jurisdictions, it covers crucial aspects like:

• Gas Piping: Materials, installation methods, sizing, and pressure regulation.
• Appliances and Accessories: Standards for safe operation and venting.
• Venting and Combustion Air: Ensuring proper exhaust and air intake for appliances.
• Safety Devices and Controls: Limiting risks through valves, regulators, and other safeguards.
• Hydrogen Blends: Addressing the emerging use of hydrogen gas mixtures.

Key Features:

• Prescriptive and Performance-Based: Provides clear rules while allowing flexibility for innovative solutions.
• Regularly Updated: Reflects advancements in technology and best practices.
• Comprehensive Scope: Covers diverse aspects of fuel gas systems.
• Accessible Structure: Divided into chapters for easy reference.

2018 Edition Highlights:

• Enhanced Safety: Introduction of arc-resistant corrugated stainless steel tubing (CSST).
• Flexibility in Materials: Allowing Schedule 10 steel pipe for gas piping.
• Accessibility Clarification: Specifying requirements for appliance shutoff valve placement.
• Transparency in Labeling: Requiring clear labeling of plastic vent pipe materials.
• Improved Vent Safety: Revising clearances for direct-vent appliance terminals.
