Off the gas valve will be small aluminum tubing that will lead you to pilot assembly, turn the knob to pilot position then push knob striaght in and light pilot and continuie tohold knob in for a minute or so then turn back to heating position If thermocoulpe is good flame will stay on replace thermocouple if flame dies out
Yeah, that just the thing. the heater sits under the floor and I dont see where the line comes in. Maybe it is under the house but I don't remember the gas man having to go under there before. it just sits in a whole in my floor and when I look down there, i don't see a supply tube or gas valve...?
Most likely that is where you will find it
Rick, I have a man coming to turn it on tonight. Sorry but your answer didn't help me.
