Review: Check the fan noise when you start it up - The fan make a strange noise when running. I just wanted to document this in case I need to make a warranty claim.
Review: Master heater - Seller delivered on time. The heater works good. I guess I read more into description than was there in that, once it shuts off it will not relight by itself. It has to be manually lighted by pushing knob. I had an external thermostat that plugged in front of heater that I used in past & heaters would relight by their selves. Apparantly all newer heaters are this way for 150000 btu & less. All in all great heater quiter than old one . But has to run all the time you can vary output ok which helps some.
