11. Power Supply
The power outlet is located behind the control box on
the back of the appliance, lower left corner. Check the
wall receptacle for 120 volt, 60 Hz (standard current).
Make sure the outlet is grounded and has the correct
polarity. A good surge protector is recommended.
12. Red Call Light
The red call light is on the side of the junction box,
below the fuse. The function of the red call light is to
indicate that the thermostat is calling for heat.
13. Reset Button
The reset button is located on the back of the appliance
in the upper right corner below the heat output control
switch. The function of the button is to momentarily
open the thermostat circuit, which restarts the system.
14. Thermocouple
The thermocouple is located on top of the firepot inside
the thermocouple cover (ceramic protection tube). The
thermocouple sends a millivolt signal to the control box
indicating the preset temperatures of the green and red
lights have been obtained.
15. Thermostat
The appliance is designed to run on a 12 volt AC
thermostat. The heat anticipator should be set on the
lowest setting available.
16. Snap Disc #1 (Convection Blower) 110°F
Snap disc #1 is located on the right side of the
appliance behind the right side panel. 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 (Fuel Delivery Interrupt) 175°F
Snap disc #2 is located on the center of the convection
plenum above the convection blower. There is an
orange and a black wire 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. If this occurs
you will have to manually reset the snap disc.
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 reset button.
There are two gray wires connected to it. 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 right side
of the appliance behind right side panel. There are
two red wires attached to it. 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.
