Ok as I said in a previous post on how my stove had black smoke from the exhaust. Also the glass was getting black a little faster. I just cleaned a couple of things I never knew anything about or how to before. On a weekly basis I would just clean the normal stuff; burn pot, glass, behind firebox wall, tubes. So after hearing from a couple of members on here and doing so googling I opened up the combustion blower, cleaned the combustion fan,and chamber. It was so full of crap, alot of crap. What a difference stove is operating awesome. Its even quieter. The start-up was also a lot quieter. I cleaned the exhaust piping. I didn't have any real cleaning brushes so i brainstormed and took my telescoping snow brush and it worked like a charm. Being a noob and on my second season I had no idea. I had a service guy over during the summer and he did the lead blower thing. I guess you just need to get in there to get everything. So for any other noobs out there. Hope this helps you out too.
