I'm curious if others have encountered this. During the really cold spells, I notice that if I don't scrape the burnpot after 3-4 days, the pellets really build up. So much so that there's a layer of black, semi-burned pellets that sit on top of the red hot ones. This seems to really diminish the heat output.

Well last week I had to travel for business (4 days), but I made sure the stove and setback thermostat were all set for the family while I was away. When I came home, the burnpot was overflowing with the semi-burned pellets I described... see attached photos.

Anyone know what causes this or how to prevent it? I have my feed rate set to 3-4.

Thanks!

Looks to me that your feed rate is to high. Have you done the 1" test that is recommended?
 
I don't have the exact stove as you but I'd have to say that it's not burning properly. I scrape the burn pot every day to eliminate the speed bumps that build up on the slides and bottom. If I don't the flame gets lazy and no longer lays along the heat exchanger fins. I keep the feed rate set at 3. You may want to set yours lower.
