No Ignition Of Gas
When I turn on the heater, I hear a click, but there's no ignition of the gas; therefore no flame. I have checked the outlet flow and there's plenty of flow. The gas is turned on. In the past year, I experienced the flame coming on, it would then go off on its own, turn off for 30 secs and then reignite on it's own and stay on
