Re: Natural gas gravity air feed furnace
Automatic Cut Off, it should cut off the gas to the pilot light if the pilot light goes out. It is controlled by the thermocouple. You over ride it when you put the control in the pilot position and hold it in until the thermocouple heats up after you light the pilot. If it is not working and the pilot light gets blown out it would allow gas to continually flow. Possibility of an explosion.
