Hey this is my first post. Been a long time browser but never posted. Anyway, I am having a terrible time. I have a home with a basement. The house has an open fireplace on the ground floor and a buck 27000 in the basement. I use the Buck stove a lot and I love it, but the problem is when it isn't being used. If I go 2 or 3 days without a fire in the Buck, my home will begin to smell like a stovepipe. It is very frustrating. Also, the fireplace upstairs smells terrible as well if it is not being used. I love burning wood and don't want to have to stop but I just don't know what to do. I have a chimney that has a true double flue (one for upstairs and one for downstairs). When the problem first started, we assumed the chimney wasn't tall enough, so we added about 2 feet to it. This did not solve the problem, so we ordered a top sealing damper for the fireplace side and even with it closed the upstairs still smells like a chimney. I essentially have to live downstairs (and keep a fire in the Buck stove) to escape the smell. As I said, if I go without a fire in the stove for more than a day or two, it starts smelling as well. I would appreciated any help any of ya'll could give as I have done just about all I know to do short of bricking the stupid openings up and swapping to all central heat. Thanks!!
