I am starting to regret replacing my wood stove with a pellet stove. I was hoping for an easier method of getting accessory heat during nights and days below 32. I bought a used Englander 55PDV22 and I have had my share of problems. No need to list the hassles that I have resolved but now I am finding that the stove goes out at times and the reason is the pellets dont slide down the hopper as they should. I will have about 20 pounds of pellets in the hopper and a void will form over the auger intake and it goes out. Anyone else have this issue. I have tried several different pellet brands. Thinking of waxing the inside of the hopper. Is this idea as dumb as it sounds to me? Any advice?
