I purchased a King 5502M and a ton of AWF pellets from Tractor Supply a couple of months ago. This is my first pellet stove so I don't know much about them. My pellets are nice and dry but it has burned out twice (flame gone out). It has temperature settings and so far it has gone out on settings "1" and "2". Am I doing something wrong? Does anyone have any advice for this model? Also, ash builds up in the two back corners of the burn pot. This seems like a great forum. I'm glad I came across it.
