I just bought 20 bags of Hamer's Hot Ones for $3.74 a bag. I set the stove for 3 and was very impressed with the heat they were putting out, until the stove overheated (flashing 4 on the display). I have the feed trim at 1 and combustion air at 5. Is there such a thing as a pellet that is too hot? It's not like I had the stove on the highest setting. I think the stove should be able to handle the heat that these pellets put out. What should I do? Should I call the dealer for service?
