I got my stove installed a few days back. Runs great except for one problem. I consistently see beads of smoke coming from the exhaust pipe even after 1 hr into my burn. I think I can even smell it. (Mt. Vernon AE by the way.) I had my installer come back to re silicone around the pipe and the top vent adaptor thinking that would do the trick. Still spits out smoke. Guys, how is that possible? Those two pieces are screwed and siliconed together yet smoke gets through. Is it possible the leak is coming from somewhere else that I am not seeing? BTW, I've only run the stove three times thus far. HELP!!
