I bought two of these for my garage (heating two rooms independently), American made and reflective of this. The installation was straight forward & easy. I'm very pleased with them. ACF shipped them promptly and followed up well with questions and minor service/shipping issue. These buys were a great value. One determining factor is that these furnaces are separate combustion ready... as one of my rooms is a woodshop with solvent fumes. This made the purchase very much well worth it. Very happy customer.
I built a 2 car garage and I needed heat. This heater did the trick. Works GREAT.
Installation was fairly simple. Had to read instructions a few times to find all requirements. The drawings do not contain some critical dimensions. Getting the heater up to the ceiling was the hard part but with my wife's help we got it done without injuries. The holes on the air intake box do not line up with the holes on the back of the heater but I was able to make the connections fit. The heater started without any problems. Fairly quiet. I had LP gas line to garage but had to extend it up to the heater. I called LP gas supplier to check gas line installation.
Quieter than I thought it was going to be, happy so far
