I cleaned my stove pipe the first week of February just before installing the p68, I cleaned it today. What a change. All I found was a thin layer of deep brown powder. This stove burnes a lot hotter than the one I had. I am burning the same pellets. This stove keeps surprising me.
I cleaned the stove pipe for my P-61 back in February for the first time with the same results. The stove is 5 years old!
The lesson is to spend it right, once! I was afraid to spend the money at first. I didn't know what I was getting into. It seemed to be a reasonable thing to do. After a few years hanging out with this crowed, I was also to realize I need to made another change if I ever wanted to achieve the desired comfort level while heating with pellets. This sure was a good year to make that change. No regrets here.
I am proud to have seen the evolution... You were contempt with your Napoleon. And always kept it clean.. But then you went and became a bottom feeder. And seen the light.. I can't talk much because I became a bottom feeder myself this winter. Congrats on the switch Save$...
