Our stove has been working fine this season. I left my house for about twenty minutes and when I came home, the smoke smell was overwhelming. First thought was the stove so I went to check it and there was smoke coming out of the side near the top. I turned off the stove and opened the windows to air out my house. We called Quadrafire customer service and all they could say is it must be an extremely windy day (it's not) and the smoke blew back into the house upon start-up. Even if that was the case, how is it acceptable? I can't have my house smelling like smoke. Good thing I came home when I did or who knows how much smoke would have filled my house. We opened the hopper and the back and there does not appear to be anything out of line. There is no error code registered on the thermostat. Any ideas???
