Hello I’m trying to dial in my pellet to air ratio. So when I turn my damper all the way down and tried to keep the flame burning correctly I have to turn the pellet auger all the way up and it still can’t keep up After about 15 minutes the burn pot is almost empty. So I take out the exhaust motor assembly the damper door is missing about a quarter of an inch on both sides looks like it’s just may be disintegrating with age of machine .I did see that they make an upgrade kit for the damper but also I suspect they may have the wrong auger motor it’s a 1 RPM and I think I should have a 2 RPM for the fact that the pellets can’t keep up so for now to fix a damper problem I blocked off the air intake just a little bit and now I seem to have some control over the damper not much but some but the pallet auger has to be turned up all the way and it barely keeps up does anybody know the correct RPM motor for the auger and has anybody had any issues with the damper door starting to disintegrate. Thanks Mark
