I have been looking at a St Croix stove. The auger gets power through a pressure switch. That is, instead of firebox vacuum it works from exhaust pressure.
If the exhaust after the comb fan has no pressure then the auger gets power. So if the exhaust is not plugged then the auger feeds. It seems like a bad & smoke filled room if the comb fan stops working. Still no pressure in that case which will cause smoke & over firing. Also, suppose the hose deteriorates......then no matter what the auger gets power with a plugged exhaust.
This seems like a bad design. How many other stoves are designed like this?
