Hi- I have a 20 year old natural gas Lear Siegler space heater 4' x 3' with a fan and smoke stack. If the power goes out in tonight's blizzard, how do I get the gas to turn on? Even without the blower of course. The old round thermostat has 2 wires that go to the heater.
Last winter it didn't go on when the power went out. What's the millivolt thing? It's my only heat and I live in the woods. Thank you.
