So I recently installed my pellet stove and upon firing it up the past few nights, i saw a decent amount of smoke blowing out the bottom of the tee. Not knowing any better, I used some high heat silicone and aluminum tape to seal the bottom of it better, but now I'm realizing that the bottom of the tee is used for cleanout. Now that I've done that, am I going to have a problem with the cleaning? Also, my tee had to go on a 45 degree angle in order for the pipe to line up right. The dealer said thats fine that way. Is this going to be a problem?
