Hi All, I just recently installed my pellet stove. The heat is amazing. I did have a problem with an abundant smoke smell in the house. After some investigation I realized the exhaust port at the back of the stove was not properly sealed at the factory. It was sealed partially with some black soft goo. I called my dealer and he looked at another one he had and said his was sealed with red Hi-Temp silicone. We both came to the agreement that I should try to clean of the black goo and re-seal with rutlan 600 degree silicone. If that did not work he would pay for return delivery and take care of the problem. So I spent the better part of a Saturday removing the whole exhaust port and sanding it down clean and re-attaching it. I took my time and it turned out great. So now I am looking over every part to check it all out before it gets cold. I did notice on the pipe that goes from the combustion blower to the bottom of the burn pot was nicely sealed except for a small hole about the size of a pencil eraser. Everything else was sealed with red silicone but this hole. Is this a problem? Should this hole be covered up and sealed or is it needed for some sort of air exhaust for the hi temp swith? Second on the convection blower I noticed it is not fully sealed to the stove. There is no sealant. I assume that was manufactured that way for a reason. Any help would be appreciated.
