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 over fire
condition should occur or if the convection blower should fail
to operate.

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.
