When I attempted a pre burn on my new HP 22 pellet stove the Room Blower Assembly was not working. ( Technically: the motor was receiving 119 volts AC and was drawing 5.9 amps.) in other words, the blower motor that sends warm air into your living space was locked up. Long story short: I contacted Comfort Bilt via their website and they promptly sent me a new compleat assembly. Free of charge. After installing the new fan assembly it has worked flawlessly. After this slight bump in the road, this is one of the best purchases we have ever made. We had a large wood stove before the Pellet Stove and we love it. Obviously it is a little more maintenance but, no more chopping or splitting wood or purchasing split wood ( with the bugs especially ants) and all the other dirt,dust and other stuff that comes through the door when you bring in wood. This stove puts out more heat than the wood stove AND it’s really nice to hit the start button on the remote and enjoy heat right away on cold winter mornings.
