The first year (2011-2012), the Chinook was AMAZING. I made many posts here, as it was the first year it was available and I was eager to post the incredible results to everyone. The Second year (2012-2013) The results were ok. I had some issues with it every now and then, but I attributed it to saying my chimney cap kept getting clogged. So I swept often, and my brain pretended the problems went away after each sweeping. I didn't post here very much because it started to get frustrating. At the end of the year I just gave up on it, and let it sit until now. Since it's getting cold and I never cleaned the stove at the end of last season, I decided there's no time like the present to give this old pain the the rump a cleaning and get it ready before the cats and wife freeze to death. I scrape most of the creosote off the walls, behind the head shield.. Then I decide I'd better check out the catalyst. It looked dirty, but I poked my head all the way up in there and saw something I didn't think was quite right. That's the top of the catalyst. Anyone have any thoughts on this? I'm going to email it over to BK to see what they suggest I do and what happened. But I figured I'd post it up on hearth to see if anyone has had a similar situation. This BK was used 2 seasons... 1 1/2-2 cord mainly Pine/Catalpa mix the first season, 1-1/2 cord Ash last season. All about 15-16% MC. edit; Just as a refresher, I have a 792sq/ft house so this stove spent probably 85-90% of it's time burning on 1. It only went on 3 for reloads, and it would sit on 1.5-2 to warm up the house (and clean the cat) for about 15-30 minutes if it was chilly in here because I forgot to load it. Ten it would go back down to 1 for a day or two.
