I just purchased and installed my first pellet stove at my cabin in northern Michigan. It's a Quad-ra-Fire and the model is the Santa Fe. My cabin is 1000 sq. ft. With cathedral ceiling in the living room with a loft above the other living space. It's 2x6 construction and well insulated. I don't seem to be able to get the temperature above 72 degrees in the living room where the stove is located and 68 in the rear area of the cabin. This is with the hopper chute open all the way and the fan on high. This is where I'm really confused. There seems to be as much heat going out the exhaust as entering the living area. It is direct vented out the wall. Is this natural? There's two small slide doors next to the burn pot to dump ashes into the ash container. Should I leave these open when using the stove? I'm not sure what pellets I'm burning because I'm back downstate. I know there made in Michigan and are three letters. Any suggestions would be appreciated.
