I was concerned with the amount of ash building up. I adjusted the feed rate from 3 to 4 and it seems like the amount of ash is decreasing, but there still seems to be a lot. Being my first season burning, I really dont have anything to base whether or not it is a lot of ash. I am considering setting the feedrate at 5 as long as im not pushing embers into the ash pan. Does anyone set their feedrate that high? Is there a correlation between feed rate and quality of pellet? Any responses are appreciated.
