Worked correctly

Heater works fine it just don't put out much heat compared to a infared heaters in my home. I have a Procom 10000 BTU and a DynaGlo 12000 BTU and they cycle less meaning less gas usage with the same temperature kept. This one is either on lower settings 16000 BTUs or high 20000 BTUs, yes thermostatic. I did test this one compared to the smaller 10000 BTU infared Procom. I timed the bigger blueflame and unhooked it and installed the smaller infared the smaller one cycled less in a hour and was off longer between cycles. I do give it 5 stars because it worked correctly and the build quality is always better with DynaGlo. My home is drafty so that may have something to do with it not working as good.

make sure your thermocoupler is raised up a bit from the manufacturer setting I had to raise mine in order to get the pilot light to stay lit now it's working fine
