Blowers & Feed Motors

Kozi 100 Insert, 100 XL, Baywin, KSH Shop Heaters, Model 100, and Previa pellet stove models will use the 120V Exhaust Fan, part number FAN12003. This fan is also referred to as the combustion blower or draft fan motor. We offer the OEM full assembly replacement as well as USA and import aftermarket motor kits. The exhaust fan pulls air through the burnpot, up past the heat exchange tubes, forcing the exhaust out of the flue vent pipe. Keeping your stove and venting clean and free of ash blockages and heavy build-up will put less strain on the exhaust fan allowing better performance and longevity. If you are noticing a lazy fire, vacuum switch tripping, or loud noises coming from the exhaust fan, you should inspect and replace if needed.

There will be a 6″ round gasket that goes from the exhaust motor to the housing, and an oblong gasket that goes from the exhaust fan housing to the stove manifold. It's important to inspect and replace these gaskets to ensure proper seal. Always make sure you use high temperature sealant around the adapter on the exhaust fan that goes to your vent pipe; we always want to make sure there are no exhaust leaks.

If you are purchasing one of the exhaust fan kits, please see our video below for an installation guide.

Kozi 100 Insert, 100 XL, Baywin, KSH Shop Heaters, Model 100, and Previa pellet stove models will all use the same circulation fan, part number FAN12001. This fan is also referred to as the convection fan or distribution blower motor. We offer the OEM full assembly replacement as an aftermarket motor kit where you utilize your existing blower housing. The circulation fan circulates room air through the impeller wheel, forcing the air through the heat exchange tubes, and dispersing the warm air into the room. As the circulation fan wears over time we will often notice less air coming out of the front of the stove, squealing or grinding when the fan is in operation, and/or our high limit switch tripping. It's important to clean your convection fan on a regular basis. Clean the dust and debris from the motor windings and the motor impeller wheel; compressed air and a dry paint brush can work very well. Check the motor label, as some do require annual lubrication. Be sure to inspect the circulation fan gasket and replace when worn or broken. When it comes time to replace your circulation fan, follow along with our general guide videos below.

The Kozi auger feed motor used on all pellet stove models is a 1 RPM clockwise (when facing shaft) gear motor. We offer several USA made and import replacement motor options. As this motor turns, the auger shaft delivers them up and drops the pellets down the chute into the burnpot. There are many safety switches in line with the auger motor such as the vacuum switch, high limit switch, and low limit switch depending on the Kozi model. As auger motors get weak they will often make abnormal noise in operation and will no longer have the torque to deliver fuel consistently. If your auger motor is not turning at all, you can test the motor to direct power to determine if it's the motor or one of the safety switches not allowing it to operate.

When it comes time to replace your auger motor follow along with our general installation guide video.
