When filling a tank directly supplying a fuel burning appliance, how should the filling terminate?

The correct approach for terminating the filling of a tank that supplies a fuel burning appliance stipulates that it should stop 2 feet away from any building opening. This requirement is in place to ensure safety and to minimize the risk of fuel leakage or spillage coming into contact with any part of the building. This distance helps prevent any potential fire hazards and ensures that fumes from the fuel do not invade the structure, which could pose health risks to occupants.

Adhering to this regulation is critical in maintaining compliance with safety standards while also ensuring that the operation of fuel-burning appliances is safe and efficient. It emphasizes the need for a buffer zone that is designed to protect both the structure and the people within it from fire hazards associated with fuel storage and usage.
