stove is a quadrafire mt vernon non AE. Its my fathers stove. I went over his house the other day because long story short he was thinking about rerouting his pipe and the local stove company was going to screw him. So I went over to look at it and found the gasket on the bottom of the door was missing. so only three sides were sealed. bottom was wide open. Put a new gasket on it and now he is saying the stove is extemly hot and the glass is getting a white soot to it and the stove is giving off that new stove smell but the stove is 4 years old. What is going on here? Am i missing something. the stove pipe is vented 3 ft vertical and 3 feet horizontal out the wall. I dont agree with the piping but i dont think this is his issue. So to recap the stove is burning real hot, he is getting that new stove smell and the stove is 4 years old and the glass is white in color.
