Bought one of these stoves and get no heat! Nice flame, glass gets warm, flu gets warm, but blows cold air. on the highest setting you get some warm air but if you move your hand more than a foot where the heat blows out it gets cool again. Installed in an insulated basement athat ewas easily heated by the base model we upgraded from. Wanted something that was more self sufficient but we are going to return it and keep the base model for now. Tried different setting, read the manual civer to cover 3 times, different pellets, even tried it outdoors to see if there was a venting issue. no changes. Too bad the air coming out of the front was not as hot as the air coming out the back. I work during the week when customer service is open. When I treid to call on a snow day(12/27) the line was busy all day and they were closed 12/31! I sent an 2 e-mails my issues and the response I got was I had to call!
