Scope and Applicability
The International Fuel Gas Code (IFGC) is a model code developed by the International Code Council (ICC) that regulates the design, installation, and inspection of fuel gas systems, including piping, appliances, and venting systems. The IFGC applies to new and existing buildings, including residential and commercial occupancies.
Key Requirements
The IFGC sets forth requirements for the design, installation, and testing of fuel gas systems, including material standards, sizing, and safety controls. The code also covers electrical connections, venting systems, and combustion air requirements.
2018 Edition Changes
The 2021 edition of the IFGC includes several significant changes from the previous edition. The following table summarizes some of the key changes:
| Requirement | Previous Edition | Current Edition | Impact |
|---|---|---|---|
| Material standards for fuel gas piping | AWS D1.1 | ASTM F2788 | Updated material standards for improved safety and durability |
| Testing and inspection procedures | Visual inspection only | Includes leak testing and pressure testing | Enhanced safety and reliability of fuel gas systems |
| Electrical connections for fuel gas appliances | No specific requirements | Requires listed connectors and wiring | Improved electrical safety and reduced risk of ignition hazards |
| Venting system requirements | No specific requirements | Requires listed venting systems and clearance distances | Reduced risk of carbon monoxide poisoning and improved indoor air quality |
Who Needs This Standard?
The IFGC is essential for engineers, inspectors, and manufacturers involved in the design, installation, and inspection of fuel gas systems. This includes:
- Engineers responsible for designing fuel gas systems
- Inspectors who verify compliance with the code
- Manufacturers of fuel gas appliances and equipment
- Contractors who install fuel gas systems
