Rick, glad others are also finding your heater set up to be great. The heater come on and off with the dropping or rising tem. If I have the same on as you do? This one I have also came from Lowes. I don't know if you have had any trouble with the ignitor, but they are famous for going out quit often. And you can only get them from mfg. They run around 25.00 to 30.00 each. And due to the glass front not to easy to light the pilot with a match but it can be done. Hope the info. helps. James
