Reference Materials
7. Heat Exchangers
The heat exchangers transfer hot air from the exhaust system
into convection air. Lift the stove top to access the heat
exchangers. There are 2 clean out rods located under the
heat exchangers.
8. Heat Output Switch
The heat output switch is located on the upper right side panel.
The function of the heat ouput switch is to regulate the burn
rates; low, medium, and high settings.
9. Igniter
The igniter is mounted on the base of the firepot. Combustion
air travels over the red hot igniter creating super heated air
that ignites the pellets.
10. Junction Box And Wiring Harness
The junction box is located on the right side of the appliance,
behind the interior shield. The junction box and wiring harness
are replaced as one component.
11. Power Supply
The power outlet is located on the back of the appliance,
lower right 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 front of the junction box, next to the
reset button. 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 right side of the apppliance
next to the red call light. 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.
When describing the location of a component,
it is always AS YOU FACE THE FRONT OF
THE APPLIANCE.
2. Convection Blower
The convection blower is mounted at the bottom rear of the
appliance. There are 2 impellers, one on each side of the
motor. The convection blower pushes heated air through the
heat exchange system into the room.
3. Combustion (Exhaust) Blower
The combustion blower is mounted on the lower left side
on rear of appliance. The blower is designed to pull the
exhaust from the appliance and push it out through the
venting system.
4. Feed System
The feed system is located in the hopper under the feed
motor cover box on the left side of the appliance and can
be removed as an entire assembly. The assembly includes
the feed motor, mounting bracket, bearing and feed spring
(auger). The hollow feed spring (auger) pulls pellets up the
feed tube from the hopper area and drops them down the
feed chute into the firepot.
5. Firepot
The firepot is made of high quality ductile iron and has a
cleaning pull-out rod. The floor of the firepot opens for
cleaning when you pull out the rod. Be sure that the floor
returns to a completely closed position or your appliance will
not operate properly.
6. Fuse
The fuse is located on the front of the junction box on the
right side of the appliance. The fuse will blow should a short
occur and shut off power to the appliance.
NOTE:
Do NOT open the control box. This will void the
warranty. If you need to plug in or remove the control
box you must first unplug the appliance.
1. Control Box
a. The control box is located under a small cover in the
right rear corner of the inside of the hopper.
b. There is a light located inside of the control box. The
internal light will turn green when the appliance has
reached a temperature of 200
ο
F (93°C) in the firepot
and will turn red when it reaches 600 o F (315°C).
c. There is also an internal blue light located in the upper
left corner of the control box. When you plug in the
appliance the blue light will automatically start blinking
1 blink every 10 seconds for the first 60 seconds and
then will stop.
