What governs appliance fuel supply connections in gas installations?

The governing body for appliance fuel supply connections in gas installations is found in Section 24.6 of NFPA 54, which is also known as the National Fuel Gas Code. This section provides critical guidelines on the safe installation and maintenance of gas appliances and the associated fuel supply systems. It addresses aspects such as materials, connections, and specific requirements for various types of appliances to ensure they operate safely and effectively. Compliance with NFPA 54 is essential for ensuring safety, preventing hazards, and maintaining a standard of practice within the industry.

While local housing codes and the International Fuel Gas Code may also provide relevant guidelines and regulations, they may vary by jurisdiction. Manufacturer specifications are important for specific appliances, but they do not govern all aspects of fuel supply connections universally. NFPA 54 serves as a comprehensive source for safe installations across many situations, making it the primary reference in this context.
