Well, I didn't buy a bag of pellets to try before I bought a ton and now I'm paying for it. I got a good deal on Somersets at TSC and didn't have a whole lot of time to shop around so I just bought a pallet. I've been through about 20 bags and after about a 4 hour burn on 4 or 5 heat range I get a clinker that blocks all of the lower holes in the burn pot and I end up w/ a mound of glowing pellets. Last night I moved the adjustable plate in the hopper to try to decrease the amount of pellets feed to the fire because I thought the combustion motor increases it's speed as the heat setting is increased. Is this correct? My thinking was that if I get more combustion air and less fuel the pellets would burn more completely. It didn't seem to help all that much, I woke up at 2am and still had a clinker that I had to clean out. Any other thoughts? I guess I need to buy some other brand pellet and blend w/ the remaining 30 bags of Somersets I have. Thanks for any help or suggestions.
