Hi everyone, I hope there is someone here that can give me some solid advice. I have a defiant non cat everburn, I cannot seem to get my stove to stay warm/hot, I get it heated to 600 and when I shut the damper, the fire goes out and the smoke starts coming out of the stove. The smoke will stop if I turn the air completely off. Which means the fire goes out. I slowly open the air little by little and eventually the smoke stops but by then the stove has cooled off so much it is only registering 350 on the thermometer. I have tried everything with this stove. We are not in an air tight house, we have a log cabin, outside masonry chimney, and we live between two rather large hills and on a lake. I think we have alot of strikes against us. We were getting alot of backpuffing, but bought a vacu stack cap and that solved that problem. But now we can't seem to get the stove warm enough to heat the home. Our home is only 1800 sq. ft. and we heat primarily with wood or was hoping too. Our chimney is three feet above the roofline. We have a 8 x 12 flue on the stove so we can burn it as a fireplace if we want to. We did have some technicians/sales rep come and inspect the stove and said it was fine, although they did replace the gasket on the bottom of the stove. We have had this stove for 4 years now and this is the first time we have not been able to hear the everburn system working. My husband and I are at wits end with this stove, and are ready to set it to the curb and put free on it. Does anyone have any other suggestions of what we can do with this damn stove?
