I have seen a lot of issues with people taking about ash build up with there englanders, I hear people modifing there burn pots and what not but I have learned this.... My hopper lid was not quite tight had a 1/16 inch gap Prob.. I adjusted the latches so it fits snug and it changed the way the stove runs... And it makes sense! With the lid slightly open air gets in the hopper down the auger tubes and into the burn pot.. Taking away from the air that's should be going straight into the burn pot.. Helping blow out the ash building up.. Just food for thought everyone
