11. Overheat Snap Discs
There are two overheat snap discs located within the
electro-mechanical cavity of the appliance. One is
mounted on the back of the drop tube in the center
of the appliance; the other is mounted in the RH side
between the firebox and cast side panel. Both snap
discs have a reset button. If the fire tries to burn back
into the feed system, the drop tube snap disc will shut
the appliance down. If there is not enough circulation
from the convection blower the second snap disc
will shut the feed system off. Either sensor must be
manually re-set if tripped. Disconnect power before
resetting.
12. Exhaust Probe - Exhaust Blower
The exhaust probe is a temperature-sensing device
attached to the exhaust blower housing via screw and
clamp. It provides sympathetic exhaust temperature
feedback to the control board. In turn, the control board
uses this information to adjust its heat-output systems
for best performance.
13. Vacuum Switch
The vacuum switch is located on the right side of the
appliance under the feed motor, behind right side
panel. Its vacuum hose connects to the drop tube.
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, plugged, or if the
firebox door is open.
14. Wiring Schematic for Control Board (below)
A. Component Functions
1. Exhaust Blower
The combustion (exhaust) blower is mounted in the
bottom right rear of appliance. The blower is designed
to pull the exhaust from the appliance and push it out
through the venting system.
2. Control Board
The control board is located on the right side of
appliance. It controls the functioning of the appliance
and communicates with the user interface through the
Bluetooth key. The control board can only be replaced
by an authorized dealer.
3. Convection Blower
The convection blower is mounted at the bottom left of
the appliance. The convection blower pushes heated
air through the heat exchange system into the room.
4. Feed System
The feed system is located on the right side of the
appliance and can be removed as an entire assembly.
The hollow feed spring (auger) pulls pellets up the feed
tube from the hopper area and drops them down the
feed chute into the fire pot. Reference the parts list for
individual parts in feed assembly.
5. Fire pot
The fire pot is made of high quality ductile iron. The
floor of the fire pot opens for cleaning and is manually
operated by the homeowner. The floor needs to return
to a completely closed position or the appliance will not
operate properly.
6. Fuse
The control board fuse will blow should a short occur.
The control board will need to be replaced. DO NOT
REPLACE THE FUSE. If the control board fuse blows
its TRIAC, that portion of the circuit, will remain closed
causing the motor on that leg to run continuously at
high speed.
7. Heat Exchanger
The heat exchanger is located behind the baffle
and transfers heat from the exhaust system into the
convection air chamber. Remove the cast iron baffle to
access the heat exchanger.
8. Hopper Lid Switch
The hopper lid switch is located on the right side, inside
the hopper. It switches the feed motor off if the hopper
lid is open.
9. Igniter (Heating Element)
The igniter is mounted on the base of the fire pot.
Combustion air travels over the red hot igniter creating
super heated air that ignites the pellets.
10. Power Receptacle
The power receptacle is located below the control
box on right side. Install the power cord (supplied
in the appliance component pack) to the appliance
receptacle. Prior to installing, check the wall receptacle
for 120 volt, 60 Hz (standard current). Make sure the
outlet is grounded and has the correct polarity. A good
quality surge protector is highly recommended to
protect the appliance electronics.
