What is the maximum allowable distance between a gas appliance and its gas supply line?

The maximum allowable distance between a gas appliance and its gas supply line is important for ensuring efficient appliance operation and safety. A distance of 3 feet is established to ensure that gas can flow without excessive pressure drop and allows for the installation of the necessary fittings and connections.

This distance also accounts for factors such as flexibility in installation, maintenance access, and ensuring that any potential leaks or issues can be easily addressed. Keeping the distance within this limit helps to minimize risks associated with gas supply interruptions and maintains appliance performance.
