Overall, very pleased with it, ...so long to the wood stove.
UPDATE: Pulled on the circuit board and furnace fired up. So, put wood shims against the board hold pressure against it and furnace is working for now. Left an email for tech support on the 22nd and it went completely unanswered. My repair man tried to call yesterday with no call back. He called today and two and a half hours got a callback, this is what their tech support had to say:
This is from the tech supports own mouth. "This unit is not reliable enough for use as a main heat source and we don't recommend it as a main heat source in case it goes down"!? Seriously? A 125000 BTU unit they don't recommend as a main heat source? INSTRUCTION MANUAL says for RESIDENTIAL/ COMMERCIAL use. It says NOTHING about not using it as a main source of heat. Their Amazon description says NOTHING about not using this unit as a main source of heat. So my repair man tells him that I need a new circuit board. He gets my information then he hangs up. No confirmation number or order number. So I don't even know if the warranted part is even on its way. Will continue to update this experience.

Very happy with it. But it uses about 8 gallons of propane per day.
