What does the National Fuel Gas Code regulate?

The National Fuel Gas Code primarily regulates the installation and maintenance of appliances that utilize fuel gas and the gas piping systems that deliver this gas to them. This includes not only the installation of gas appliances, but also ensuring that the plumbing of the gas lines is performed safely and correctly. The code’s purpose is to promote safety by establishing standards for the design and installation, ensuring that they do not pose risks such as leaks, fires, or explosions.

The code is specifically focused on gas-related systems, which is why other areas like electrical systems, indoor air quality, and refrigeration systems are not covered under its regulations. Hence, understanding this framework provides vital guidance in adhering to safety and operational standards in HVAC practice concerning gas systems.
