What does this do? Does the button have to be depressed to get the fuel to flow? It's after the o/off valve, pres. Reg. It has 2 wires running to it. Says it req. 9v.
Were not getting any fuel to stove, refer etc.
Says safety valve on it? Seems to me it may be a safety shut-off in the event of a line burst dumping fuel? I don't ever remember depressing the silver button to start fuel flow for appliance opperation.
