His only regret is that he didn't get the auger version. I never have ANY unburnt coal due to the burn pot design. He always has some unburnt coal in his ash even when we both get the coal from the same supplier. Plus I have the flexibility to be able to burn wood pellets if I wanted to. He's not able to do that.
Just make sure that when you're only using one burner it's the back one. You don't want to have to reach over the fire to get to that second one so that you can light it. Ouch!

Intuitively everybody wants to squeeze the last btu out of the coal, but if that is accompanied by cooling air being blown into the combustion chamber through dead ash, it works against the production of usable heat. My vote would be to make sure the ash ring is right and be prepared to see at least a small amount of unburned coal.
mdrelyea wrote:There are no adjustments on the ash ring or combustion blower that I'm aware of. The manual certainly doesn't mention any. The only 'setting' I have is a switch on the combustion blower for high or low speed. The manual says that low speed is for when burning pellets.
My understanding is that the older underfeds have combustion blowers that cycle on and off. Mine is on all the time.
