    On the advice of many, I decided that once a week I should shut down completely, cool off, and do a good cleaning. Today I did this. While cleaning the burnpot, I scooped out all material from it, and found that there were some hard deposits on it, on the surface that curves out of sight. But I could feel them, and although it took a screw driver, I got them all off. They must have been clogging some of the air holes. Now the stove is running very, very well - beautiful flame, and the warmest stream of air out the front that I have felt in a while (this is on Stove 7, feed rate max). I know I am getting efficient burning and high capacity.

    The dealer told me that deposits could feel like steel but they had to be removed - I saw that, and will make sure I clean this well every week.

    Most problems people have on this site are caused by not cleaning thoroughly. Remember this when doing a major cleaning and life is good.

    not sure if your burnpot is removable or not-mine is and it is stainless steel.At first,I had a heck of a time getting the hard deposits off but now I throw it into a pot of water and let it sit for a bit-water softens up the deposits nicely and they come right off with mininal scraping(I use a putty knife).

    Interesting - as far as I know, the Harman XXV burnpot is not removeable.

    An update - today I cleaned thoroughly (after 9 days), and the deposits I found before, in the "out of sight" area, had returned, but since they were only 9 days in the making they were not too hard to remove. Once again, I started back up with high performance !!! Nice heat coming out, lots of capacity.

    I used to do a quick scrape everyday after work, no need to shut it down if you use the right tool,
    should only take about 30 seconds with the right tool.
