Lochinvar & A.O. Smith 100093811 Natural Gas Door Switch is an important safety component of the FG40T40 natural gas water heater. This change makes it possible for the heater to function when the access door is shut and isolating gas supply when the door is open. This reduces possibilities of gas leakage and thus improves safe operation of the equipment. Originally installed in residential water heaters, the switch increases the dependability and safety of the system. These include; protection against dangerous conditions, improved working conditions, and longer equipment life due to proper combustion conditions.
