I have been running my Mt vernon ae for about 10 hrs now and i am still getting a burning paint type smell in the back where my duravent pipe meets the top vent adapter. I have a vertical install with black pipe on the inside and up through the roof. There is no leakage anywhere since every crack has been sealed at least twice. No smoke smell, just burning paint smell! HELP! My wife is REALLY getting a headache now from this!! And we all know we can't have that!
