The problem with this is that the induction fan is the same fan that blows the smoke out from the exhaust vent; pellet stoves don't exhaust out a chimney like a fireplace. They require forced induction. When you turn off the pellet stove with the potentiometer, the fan continues running until whatever pellets remain in the combustion chamber stop burning. Simply removing power means that the pellets continue burning, but the smoke and exhaust gases have nowhere to go. They will fill up the stove and start leaking out.
