I have a ranch house with a Breckwell Big E in the basement that we use for our main source of heat. There is ductwork right above the stove to help get the heat upstairs to where it is really needed. I have also left the floor uninsulated to try to get some heat transfer through the floor as well. There was an existing chimney and I just adapted the pipe out of the back of the stove and through the clay chimney crock and turned the pipe up inside the chimney for the stove exhaust. I then sealed between the clay pipe and the double wall stove pipe with fiberglass insulation to make it "air tight". Will I get better performance and more heat if I install a flexible pipe the whole way to the top of the chimney or is it not going to make any difference? Also while burning, the stove glass does seem to get dirty fairly fast. This may just be due to the design of the stove or could it also be related to the stove exhaust? I burned it this way all last winter and never had any problems with the stove blowing out but I did have some issues with the stove going out while running on the lower settings (1 or 2 out of 5) but I attributed them to the feed rate of the auger. Thanks.
