Newbie here and need some advice. I have a Martin Venturi pellet stove. Like most pellet stoves it has forced air which also pushes the smoke out. Here is my problem... When burning there is no smoke smell at all, after I turn the stove off...which stops the fan pushing the smoke out, the next morning my basement is filled with smoke smell. I have experimented with a few differant things to no avail. Once you turn the stove off you can watch the firebox fill with smoke and it just trickles out the pipe outside, and the pot just sits and smolders all night. I have Simpson Duravent that is sealed up good and tight and I have already replaced the rope gasket on the door. I have done the dark room and flashlight thing...nothing. The only thing I can think of is that the outside draw is not pulling the smoke out fast enough. I also tried cracking the ash door and it seemed to really help push the smoke out faster. Any ideas?
