Mt. Vernon Pellet Stove
16. Snap Disc #1 (Convection Blower) 125°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.
17. Snap Disc #2 (Thermostat Override) 175°F
Snap disc #2 is also located on the right side of the appliance
next to snap disc #1 and has a red reset button. There are 2
orange 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.
18. Snap Disc #3 (Back Burn Protector) 250°F
Snap disc #3 is mounted on the back of the auger tube in
the center of the appliance and has a red reset button. To
access it remove the right side panel. 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.
19. Vacuum Switch
The vacuum switch is located on the lower left side of the
appliance behind left side panel. 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.
