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 pro
-
vides 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)
When describing the location of a component, it is
always AS YOU FACE THE FRONT OF THE APPLIANCE.
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 con
-
trol 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 appli-
ance 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.
11. Overheat Snap Discs
T
here are two overheat snap discs located within the elec-
tro-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
