Less volatiles (smoke) rolling in the stove compared to the stoker size. Stove not getting near as hot...highest temp has been 600* but only for 5 minutes. Idling at 300* with 4 chunks in stove. Loading door vents closed and under air open 1/4 ". Will see how it holds overnight but house temp is very comfortable. Thanks again. This coal came from middlesboro ky but I didn't get analysis sheet for the stove size coal so I'm not sure what exactly it is other than bit coal.
The above fire vent is more important with bit. The lower vent controls fuel bed temp and upper burns the smoke. Also if stove is in good working order you should be able to get the stove to simmer along.
