Maybe one of you engineers can explain to me how the ash gets out of the burn pot (which is about 2-1/2" deep on my new Empress stove) and into the ash pan? Having never seen a pellet stove before, I thought there'd be small holes in the burn pot to allow the ashes to fall through, but there are none. So while I'm waiting on the vent pipe to arrive next week so I can fire up the stove and see how it works, I thought I ask. (It didn't occur to me that I'd have to order the vent pipe. I guess I should have known that if the wood stove dealers in town don't stock pellet stoves, they probably wouldn't stock vent pipe either.) BTW, they are predicting lows in the mid 20's here next week. I know, for some of you that's almost summer temperatures, but for us in the "sunny south" that's moderately cold, and I guess I'll have to light the LP heater.
