2013 Harman Accentra 52i have burned about 20bags of hammers so far and gave it a good cleaning.Cleaned the holes out in the burnpot. Took off the cover on the bottom and exhaust fan cover and vacced out not much ash there.put both covers on and plates back in, empty ash pan. Got home from work there was a large mound of not burned all the way pellets in the ashpan.Cleaned the ashpan and scaped burn pot checked feed setting which was same 3.5 woke up this morning same thing, not fully burned pellets in ash pan and at edge of burn pot, lazy flame.The stove is not burning the pellets all the way to ash and seems to be over feeding.Any advice ?
