Hi Everyone, I've posted a couple of times. New pellet stove owner of a inherited 2006 Mt Vernon Quadrafire classic (lightly used by my parents - maybe 10 tons max, but a bit rusty because their basement had some humidity in it). New install in two story old chimney by me of..... Duravent Praire cap, whit 4" exhaust up, 3" OAK down the chimney. Plate at bottom of chimney in firebox to block off the stinky old wood burning chimney. Mt Vernon burns fine based on my novice opinion. Might have a tad to much air in the mixture. When it is running the house has a woody pellet scent in it. It is faint but present. I just chalked it up to the fact that burning wood in the house would probably produce some smell. However I see on some posts here that properly operating pellet stoves should not smell of any smoke. So I set about to see if I had any leaks on the stovepipe. In a totally black room with a flashlight I started the stove. Honestly the firebox never got much smoke in it (I'm not sure if they normally do), so I'm not sure how much leaking smoke I would see anyway. I had both side panels off stove. I did not see any smoke from the insides of the stove up the stovepipe. But from my prior outdoor testing and cleaning, I do know that the gasket in the picture below is bad. It may be letting a tiny bit of exhaust out. I can pass a putty knife past the gasket in some place. So I'm going to change it. Question 1: that gasket looks like a basic rope gasket. I'm not sure it is a good design even when it isn't beat up. Is there a better alternative or should I mail-order an OEM gasket? Question 2: Is there some other gaskets I should be looking at. Again I don't see any smoke. Question 3: Is there a better way to do a smoke test? Question 4: I ordered another door gasket, but it has not arrived, so I will be putting that in. Would that cause a small smokey smell? Question 5: The firepot cleanout dump lever is sticky, so when I pull it the firepot inches up a bit, it is bound up. I can free it but it never really moves freely. It will make the front of the pot pop up a little bit. If I help move it with my hand (the trap door) while operaing the pull lever. i can free it up. I will put a gasket on the pot at some point. Could this lack of gasket cause smokey smell? Thanks for taking time to read this!
