i cleaned out my stove and changed out a few parts and it was running great.. Seems as I let it run for more than a few days at a time that the air flow gets less and the burn pot gets clogged with half burned pellets... Once I scoop them up then I have the "popcorn" noise happening in the stove. I currently have the pellet stove at 4-4 and the house is a 72... I am nervous with the pot filling up and me not being home.. Any advice?
