I’ve had long term trouble with the valve opening using the thermostat.
Not getting into my history, but I’ve noticed that tapping on that vent labeled bulge, it opens up and the gas flows. The valve has always responded using the thermo to shut it off.
So, notice that there is a depression under the bulge. Is there screw, or clean out option there? Wondering if there is some residue or other accumulated issue at that location.
