I have what seems to be a thermopile in the back of a NG space heater.The 2 wires run to what seems to be a thermostat to shut off the pilot light if the heater gets too hot. I can't get the pilot light to stay lit. I've bt passed the thermopile and it works. Can I run the heater without it? I have attached some pics to help explain. Thx. OOPS! It says my files are too big. Help!
