CB 1200 Pellet Stove
16.Thermostat
The appliance is designed to run on a 12 volt AC thermostat. The heat anticipator should be set on the lowest setting available.
17.Snap Disc #1 (Convection Blower) 145°F
Snap disc #1 is located on the right side of the appliance on the top of the heat exchanger box. There are 2 purple wires connected to it. This snap disc turns the convection blower on and off as needed. Power is always present at snap disc #1.
18.Snap Disc #2 (Thermostat Override) 200°F
Snap disc #2 is also located on the right side of the appliance between snap disc #1 and convection blower. There are 2 yellow wires connected to it. This snap disc will turn off the feed system, which will turn off the appliance if an overfire condition should occur or if the convection blower should fail to operate.
19.Snap Disc #3 (Back Burn Protector) 250°F
Snap disc #3 is mounted on the back of the auger tube in the right side of the appliance just below the feed motor and has a red reset button. To access it remove the feed motor cover box from inside the hopper. If the fire tries to burn back into the feed system or push exhaust up the feed tube, this snap disc will shut the entire system off. This disc must be manually reset.
20.Vacuum Switch
The vacuum switch is located on the left side of the appliance behind the inner shield. This switch turns the feed system on when vacuum is present in the firebox. The vacuum switch is a safety device to shut off the feed motor if the exhaust or the heat exchanger system is dirty or plugged or if the firebox door is open.
