A.Design, Installation & Location Considerations
1. Appliance Location
OTCheck building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, fire
officials or authorities having jurisdiction over restrictions,
installation inspection and permits.
It is a good idea to plan your installation on paper, using
Getting Started
Since pellet exhaust can contain ash, soot or sparks, you
must consider the location of:
• Windows
• Air Intakes
• Air Conditioner
• Overhang, soffits, porch roofs, adjacent walls
• Landscaping, vegetation
When locating vent and venting termination, vent above
roof line when possible.
exact measurements for clearances and floor protection,
before actually beginning the installation
Consideration must be given to:
operation. Do NOT install damaged, incomplete or substitute
components.
• Safety, convenience, traffic flow
• Placement of the chimney and chimney connector.
• If you are not using an existing chimney, place the appli-
proved venting specifically designed for corn to prevent corrosion or degradation. Follow the instructions from the venting
manufacturer.
ance where there will be a clear passage for a factorybuilt listed chimney through the ceiling and roof.
• Installing an optional outside air kit would affect the loca-
tion of the vent termination.

R
B. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect
performance.
• Install through the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fire.
• Penetrate the highest part of the roof. This minimizes the
effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the appliance location relative to floor and ceiling
and attic joists.
• Take into consideration the termination requirements on
Page 10.
CAUTION
• Do NOT connect this unit to a chimney flue servicing
another appliance.
• Do NOT connect to any air distribution duct or system.
C. Wall Control Thermostat
The wall control’s location will have some affect on the
appliance’s operation.
• When located close to the appliance, it may require a
slightly higher temperature setting to keep the rest of
the house comfortable.
• When located in an adjacent room or on a different floor
level, you will notice higher temperatures near the appliance.
TO
T
E. Negative Pressure
Negative pressure can
cause spillage of combustion fumes and soot.
Negative pressure results from the imbalance of air available for the appliance to operate properly. It can be strongest in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
•
Location of return-air vents to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
• Install the outside air kit with the intake facing prevailing
winds during the heating season
• Ensure adequate outdoor air for all combustion appliances
and exhaust equipment
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the appliance
• Avoid installing the appliance near doors, walkways or
small isolated spaces
• Recessed lighting should be a “sealed can” design
• Attic hatches weather stripped or sealed
• Attic mounted duct work and air handler joints and seams
taped or sealed
D. Draft
Draft is the pressure difference needed to vent appliances
successfully. When an appliance is drafting successfully, all
combustion byproducts are exiting the home through the
chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
OT Hearth & Home Technologies assumes no
responsibility for the improper performance of the chimney
system caused by:
•Inadequate draft due to environmental conditions
•Downdrafts
•Tight sealing construction of the structure
•Mechanical exhausting devices

Mt. Vernon Pellet Stove (AE)
F. Fire Safety
To provide reasonable fire safety, the following should be
given serious consideration:
• Install at least one smoke detector on each floor of your
home.
• Locate smoke detector away from the heating appliance
and close to the sleeping areas.
• Follow the smoke detector manufacturer’s placement and
installation instructions and maintain regularly.
• Conveniently locate a Class A fire extinguisher to contend
with small fires.
• In the event of a hopper fire:
• Evacute the house immediately.
• Notify fire department.
WARNING
Fire Risk.
• Do not operate appliance before reading
and understanding operating instructions.
• Failure to operate appliance properly may
cause a house fire.
WARNING
Hearth & Home Technologies disclaims any
responsibility for, and the warranty will be
voided by, the following actions:
• Installation and use of any damaged appliance.
• Modification of the appliance.
• Installation other than as instructed by Hearth & Home
Technologies.
• Installation and/or use of any component part not approved
by Hearth & Home Technologies.
• Operating appliance without fully assembling all
components.
• Operating appliance without legs attached (if supplied with
unit).
• Do NOT Overfire
Or any such action that may cause a fire hazard.

OT
Do NOT Terminate Vent:
• In any location that will allow flue gases or soot from enter-
ing or staining the building
• In any location which could create a nuisance or hazard
• In any enclosed or semi-enclosed area such as a carport,
garage, attic, crawl space, under a sun deck or porch,
narrow walkway
• Closely fenced area, or any location that can build up
a concentration of fumes such as a stairwell, covered
breezeway, etc.
OT
Termination must exhaust above air inlet elevation.
• It is recommended that at least 60 inches (1524mm) of
vertical pipe be installed when appliance is vented directly
through a wall. This will create a natural draft, which will
help prevent the possibility of smoke or odor venting into
the home during a power outage.
• It will also keep exhaust from causing a nuisance or hazard
by exposing people or shrubs to high temperatures.
• The safest and preferred venting method is to extend the
vent vertically through the roof or above the roof.

The chart will help you in determining proper venting size
according to the equivalent feet of pipe calculated in Vent
Termination Calculation Table and the altitude above sea
level of this installation. See Figure 12.1.
Locate the calculated equivalent feet of pipe on the vertical
left side of the chart. Move to the right horizontally on the
chart until you reach your altitude above sea level.
If you fall below the diagonal line, 3 or 4 inch (76 to 102mm)
pipe may be used. If it is anywhere above the diagonal line,
a 4 inch (102mm) diameter pipe is required.
The chart reveals that a 90° elbow is 5 times as restrictive
to the flow of exhaust gases under positive pressure as one
foot of horizontal pipe, and a foot of horizontal pipe is twice
as restrictive as a foot of vertical pipe.

CAUTION
Tested and approved for wood pellets, shelled field
corn, wheat and black oil sunflower seeds. Burning
of any other type of fuel voids your warranty.
A. Fuel Size, Material and Storage
1. Wood Pellets
Wood pellets are made from sawdust or wood by-products. If
the source material is hardwood, they can have a higher mineral
content, creating more ash. Fuels containing bark will also have
higher ash content.
Minerals and other non-combustible materials such as sand
will turn into a hard, glass-like substance called a clinker when
heated to the extreme temperatures our firepot reaches. This
is what forms clinkers in the bottom of the firepot. Trees from
different areas will vary in mineral content. That is why some
fuels produce more clinkers than others.
Pellets are manufactured in either 1/4 inch or 5/16 inch (6-8mm)
diameter and should be no more than 1-1/2 inches (38mm) in length. Pellet lengths may even vary by lot from the same
manufacturer which is why the feed rate may need to be adjusted
occasionally. If you burn pellets longer than 1-1/2 inches
(38mm) you may have an inconsistent fuel feed rate and/or
missed ignitions.
Pellet fuel quality can greatly fluctuate. The Advanced Energy
(AE) appliance has been designed to burn a wide variety of fuels,
giving you the choice to use the fuel that is most economical in
your region. Premium wood pellets have the lowest ash content,
under 1%. Standard grade pellet, high ash pellets, corn and
other biomass fuels all have higher ash content.
The higher the ash content, the more often the ash pan will need
to be emptied. Premium wood pellets will produce the least ash
and tends to produce the highest heat output.
Pellets made from hardwoods (i.e. oak) have a higher ash content
than pellets made from softwoods (i.e. pine). The hardwood
pellets may require more air to burn properly so make sure you
have the wall control on the correct setting.
If you are burning a higher ash fuel and your firepot and ash pan
are filling quickly, set the wall control on “Utility Pellet” and the
auto-clean system will empty the firepot more frequently.
Always burn dry fuel. Burning fuel with high moisture content
takes heat from the fuel and tends to cool the appliance,
robbing heat from your home. Damp pellet fuel can clog the
feed system.
We recommend that you buy fuel in multi-ton lots whenever
possible. However, we do recommend trying various brands
before purchasing multi-ton lots to ensure your satisfaction.
R
2. Other Fuels
This appliance has been tested and approved by Hearth &
Home Technologies for shelled field corn, wheat and black
oil sunflower seeds.
When purchasing corn or wheat to burn in your appliance,
read the ingredient label very carefully. Do NOT purchase fuel that contains any additives such as oils (i.e. soybean
oil) and meals as it will result in poor unit performance. If
you are buying corn or wheat the only ingredient that should
be listed is corn or wheat.
Shelled field corn must be 15% or less moisture content. The
corn must be clean and free from debris. Never burn corn
straight from the field. Stalk parts, excessive fines and cob
remnants, etc. will clog the auger mechanism. Corn with
excessive grain dust must be screened by sifting with 3/16
inch mesh screening.
WARNING
Risk of Chemical Poisoning.
• Do Not burn treated seed corn
• Chemical pesticides are harmful or fatal if
swallowed
• Burning treated seed corn will void your
warranty
Do not burn treated seed corn in your appliance. Seed corn
is treated with chemical pesticides that are harmful or fatal if
swallowed; therefore, seed corn is dangerous to have in the
house, expecially where children can reach it. Burning treated
seed corn in your appliane will void your warranty and will
destroy the exhaust system on the unit.
When changing to a different fuel, be sure to empty the hopper
of the previous fuel and vacuum the hopper before you fill it
with the new fuel. Make the appropriate selection on the FUEL
SELECTION screen on the thermostat wall control. The burn
rate, BTU content and heat output will all vary depending on
fuel selected. See Figure 23.3 on page 23.
3. Storage
Wood pellets should be left in their original sealed bag until
using. This will prevent moisture absorption.
Shelled corn, wheat or sunflower seeds should be stored in
a tight container where it will not absorb moisture from damp
or wet floors. This will also prevent rodents from becoming
a problem.
Do not store any pellet fuel within the clearance requirements
or in an area that would hinder routine cleaning and
maintenance.

B. General Operating Information
See Wall Control Thermostat Manual
for detailed operating instructions.
1. Wall Control Thermostat - Automatic Setting
The appliance is like most modern furnaces; when the
wall control thermostat calls for heat, your appliance will
automatically light and deliver heat. When the room is up to
temperature and the wall control is satisfied the appliance
will shut down.
In the automatic setting the heat output level is controlled
by the wall control. Select “Automatic” on the AUTO/
MANUAL screen. Figure 23.1.
Automatic
Manual
Off
Figure 23.1
2. Wall Control Thermostat - Manual Setting
When you select “Manual” on the AUTO/MANUAL screen
the appliance will still automatically turn on and off
according to the temperature setting. However, you will
be able to manually control the heat output levels. Adjust
the heat output levels by using the HEAT OUTPUT LEVEL
screen.
Mt. Vernon Pellet Stove (AE)
C. Before Your First Fire
1. First, make sure your appliance has been properly
installed and that all safety requirements have been met.
Pay particular attention to the fire protection, venting and
wall control thermostat installation instructions.
2. Double check that the ash pan and firebox are empty
and then close the front door.
CAUTION
Tip of thermocouple must be in contact with the inside
end of the thermocouple cover.
Missed ignitions can occur.
D. Starting Your First Fire
1. Fuel Selection
To start your first fire, you must select the appropriate fuel on
the FUEL SELECTION screen on the thermostat wall control
to match the fuel you have chosen to burn.
If the proper fuel is not selected your appliance will not operate
properly. For example, if you have selected wood pellets and
you are burning corn, the appliance may not light, may go
out or overfeed. Figure 23.3.
2. Comfort Level Selection
Once your fuel is selected, select the temperature at the
desired setting on the SET COMFORT LEVEL screen.
Figure 23.4.
3. Automatic or Manual Setting
The automatic setting will control the heat output based on
the comfort level selection. The manual setting allows you
to manually control the heat output settings. See page 24,
Ignition Cycles.
NOTE: See the Wall Control Thermostat manual for
detailed instructions.
Medium
Figure 23.2
3. Auto-Clean Firepot System
Your appliance is equipped with an automatic firepot
cleaning system that will change the frequency of cleaning
based on the fuel being burned.
The auto-clean system will clean itself immediately on initial
plug in. If there is a power outage, as soon as power is
restored it will automatically clean itself.
A properly adjusted fire with the heat output on HIGH
has an active flame pattern that extends out of the firepot
approximately 8 inches (203mm).
If the fire has tall flames with black tails and seems somewhat lazy, the flame height will need to be reduced. If
the fire is not 8 inches (203mm) tall, the flame height will
need to be increased. A medium or low setting will give
a shorter flame.
The flame will rise and fall somewhat. This is normal.
With your appliance in Manual mode and the heat output
level set to HIGH adjust the flame height using the
FLAME HEIGHT ADJUST screen on the thermostat wall
control. Figure 24.1.
Figure 24.1
F. Battery Back-up System (Optional)
The appliance has been designed to operate on an optional
battery back-up system. If you have frequent power
outages in your region, hook the appliance up to a 12 volt
battery and it will automatically switch to battery power in
the event of a power failure. There will be a battery icon
that appears on your wall control to let you know you are
now operating on battery power.
Once you are operating on battery power, you must
manually light the fire in the appliance as it will no longer
automatically light. Use only approved fire starting gel to
start the fire. The high burn rate is no longer available
on battery back-up as each level drops down one level.
For example; the high burn becomes medium high burn
and so on.
We recommend a 12 volt deep cycle battery, (i.e., marine or
RV type). If the battery charge falls below 10 volt it can no
longer sustain the appliance operation and the appliance
will shut down. A 12 volt battery cable is available through
your local dealer.
CAUTION
• Hook up to battery terminals BEFORE you
plug battery into the appliance.
• Damage to internal electronic components
may occur.
G. Ignition Cycles
The Advanced Energy engine is controlled by the digital wall
control. The digital display on the wall control will tell you what
your appliance is doing in the upper left corner, above the line
Every time the thermostat calls for heat, the appliance steps
through five cycles:
1. Ignition cycle
2. Soft-start cycle
3. Heating cycle
4. Shut down cycle
5. Cleaning cycle
The duration and characteristics of these cycles may be different with each type of fuel selected.
1. Start-Up
During this cycle:
• The igniter turns on for 90 seconds to heat up the air in
the firepot
• The combustion blower starts
• Vacuum switch comes on
• Feed motor turns on adding fuel to the firepot and the
appliance waits for the fire to start
The duration of start-up depends on the type and quality of fuel
used. It is normal to see some smoke during the ignition process as moisture evaporates and the fuel lights. The smoke
will stop once the fire starts.
If you are lighting your appliance for the first time the feed tube
is empty and it can take some time to fill it with fuel before you
will see a fire. To speed up this process, put a handful of fuel
in the firepot. You can also do this when you have run your
hopper dry.
Once the fire is lit, the appliance moves into the low soft-start
cycle as it continues to build the fire. In this cycle, more fuel
will be added. As the fire builds, the appliance will change to
medium soft-start mode and the heating cycle begins.
3. Auto / Man - L, ML, M, MH, H
There are two choices in the Automatic / Manual menu of how
your appliance will operate.
In Automatic Mode, the wall control will turn the heat output
level up or down depending on how far the room temperature
is from the desired temperature. The digital display will read
AUTO:M as an example of automatic, medium level.
As the room temperature approaches the desired temperature, the appliance will turn down to lower settings. When you
change the appliance to Manual, set the heat output setting
from the main screen. The right bottom button will read HEAT
OUTPUT.
Page 24
7034-106E
September 1, 2008
R
3. Auto / Man - L, ML, M, MH, H (Cont’d)
You can operate the appliance from any of the 5 levels. On
the lowest level, the appliance will stay on longer, burn less
fuel per hour, but will take longer to bring the home up to
your desired temperature. On the highest setting, the appliance will burn more fuel per hour, but bring your home up to
temperature more quickly.
Regardless of the heat output level, when the home reaches
your set temperature, the appliance will go into the shut
down cycle. In Manual mode heat output does not change.
Turn to OFF to stop operation.
4. Shutdown
Once your home has reached your set temperature, the
appliance will stop feeding fuel and allow the fire to diminish. The convection blower will continue to run until the
appliance cools to appropriate temperature and will go into
the auto-clean cycle.
5. Auto-Clean
The firepot auto-clean system will cycle when the appliance
is first plugged in:
• When the house reaches temperature and the appliance shuts down.
• At prescribed intervals, depending on the type of fuel
selected.
If your appliance is running and the auto-clean cycle is initiated, the appliance will revert to shut down cycle.
The floor of the firepot will open and deposit the ash into the
ash pan. It takes approximately 2 minutes to complete the
auto-clean cycle. The floor will then shut, and if the thermostat is still calling for heat, the fire will start again, continuing
the heating process.
During this auto-clean cycle, the convection blower will continue to run.

I. Frequently Asked Questions
ISSUESSOLUTIONS
1. Metallic noise1. Noise is caused by metal expanding and contracting as
it heats up and cools down, similar to the sound produced by a furnace or heating duct. This noise does not
affect the operation or longevity of your appliance.
2. Ash build-up on glass2. This is normal. Clean the glass.
3. Glass has turned dirty3. Excessive build up of ash. The lower burn settings will
produce more ash, the higher burn settings produce
less. The more it burns on low the more frequent cleaning of the glass is required.
4. Fire has tall flames with black tails and is lazy4. The flame height adjustment needs to be reduced or
the firepot needs cleaning. Heat exchanger or exhaust
blower needs cleaning.
5. Excessive smokey start-up5. Either the firepot is dirty or there is too much fuel at
start-up and not enough air.
6. Large flame at start-up6. This is normal. Flame will settle down once the fire is
established. Some smoke is normal.
R
7. Mechanical Noise7. The floor of the firepot in the auto-clean system may
make some noise as it scrapes the ash into the ash
pan.
CAUTION
Odors and vapors released during initial operation.
• Curing of high temperature paint.
• Open windows for air circulation.

C. General Maintenance and Cleaning
1. Types of Fuel
Depending on the type of fuel you are burning will dictate how
often the firepot cleans itself. If the fuel you are burning has
a high dirt or ash content or you are burning other biomass
fuels, it may be necessary to do a more thorough cleaning
during the burn season.
The auto-clean firepot system will routinely clean the
firepot, at shutdown when the wall control is satisfied or the
predetermined amount of burn time has elapsed.
A clinker is formed when dirt, ash or a non-burnable
substance is heated to 2000°F (1093°C) and becomes glasslike. Clinkers filling the ash pan will have to be cleaned out
more often than ash. Excessive clinkers will eventually jam
the auto-clean system and generate an error. Figure 31.1.
3. Cleaning Ash Pan
•Frequency:
Wood Pellet Fuel: Weekly or every 5 bags of fuel
Alternate Fuel: Daily
•By: Homeowner
Locate the ash pan underneath the firepot. Slide the
ash pan straight out. Empty into a non-combustible
container and re-install ash pan. When replacing ash
pan push it back until it catches on the 2 side latches.
See Disposal of Ashes below.
4. Ash Removal from Firebox
•Frequency: Weekly or more frequently depending on
fuel type or ash build-up.
•By: Homeowner
There must not be any hot ashes in the firebox during
cleaning so allow the appliance to completely cool.
Frequent cleaning of the ash in the firebox with a vacuum
cleaner will help slow down the build-up of ash in the
exhaust blower and vent system.
Clinker
Figure 31.1 - Large Clinker
2. Auto-Clean System Inspection
•Frequency: Monthly or more frequently depending
on fuel type
•By: Homeowner
a. The appliance must be in complete shutdown,
completely cool and the exhaust blower off.
b. Inspect the auto-clean springs for any degradation or
deformation. As the springs heat up and cool down
they can lose tension.
If there is a gap showing above the firepot floor it means
the springs have lost their tension and can not keep
the floor in the proper position.
This will cause ignition problems and fuel falling into
the ash pan. Replace them if that occurs.
c. Inspect the holes in the firepot floor for any debris.
They must be kept clear. If you are burning corn, the
holes have a tendency to fill with particles which will
need to be removed.
WARNING
Disposal of Ashes
• Ashes should be placed in metal container
with tight fitting lid.
• Ashes should be retained in closed container
until all cinders have thoroughly cooled.
5. Disposal of Ashes
•Frequency: As needed
•By: Homeowner
Ashes should be placed in a metal container with a
tight-fitting lid. The closed container of ashes should
be placed on a non-combustible floor or on the ground,
well away from all combustible materials, pending final
disposal.
If the ashes are disposed of by burial in soil or otherwise
locally dispersed, they should be retained in the
closed container until all cinders have been thoroughly
cooled.

6. Cleaning Firepot with Firepot Clean-Out Tool
•Frequency:
Softwood Pellets: Weekly or every 5 bags
Hardwood Pellets: Weekly or every 3 bagsAlternate Pellets: Daily or every 1 bag
•By: Homeowner
a. The appliance must be in complete shutdown,
completely cool and the exhaust blower off.
b. It may be necessary to use your firepot clean-out tool
to chip away material that has built up on the sides of
the firepot and to push out any clinkers. Larger clinkers
may have to be removed from the top of the firepot.
Corn clinkers can be especially difficult to break up. If
the clinker adheres to the sides of the firepot, you will
need to manually clean the firepot.
c. After cleaning the firepot and inspecting the holes,
turn off the power and then restore the power. The
auto- clean system will then clean itself.
d. The firepot floor plate must be fully closed when
finished.

8. Cleaning the Hopper
•Frequency: Monthly, every 1 ton of fuel or when
changing fuel types.
•By: Homeowner
After burning approximately 1 ton of fuel you will need
to clean the hopper to prevent sawdust and/or fines
build-up. A combination of sawdust/fines and pellets
on the auger reduces the amount of fuel supply to the
firepot. This can result in nuisance shut downs and
mis-starts.
a. The appliance must be in complete shutdown and
cool and the exhaust blower off
b. Empty the hopper of any remaining pellets.
c. Vacuum the hopper and feed tube.
9. Cleaning the Glass
•Frequency: When clear view of the firepot is obscured
•By: Homeowner
a. Appliance must be completely cool before cleaning
glass.
b. Use a damp paper towel or any non-abrasive glass
cleaner. Wipe off with dry towel.
WARNING
Handle glass doors with care.
• Inspect the gasket to ensure it is undamaged.
• Do NOT strike, slam or scratch glass.
• Do NOT operate appliance with glass door
removed, cracked, broken or scratched.
11. Cleaning Convection Blower - Requires No
Lubrication
•Frequency: Yearly or as needed
•By: Qualified Service Technician
•Task: Contact your local dealer.
12. Door Latch Inspection
•Frequency: Prior to heating season
•By: Homeowner
•Task:
The door latch is non-adjustable but the gasketing between
the glass and firebox should be inspected periodically to
make sure there is a good seal. If the gasket is frayed or
damaged, replace with a new one.
13. Soot and Fly Ash: Formation & Need for Removal
in Exhaust Venting System.
•Frequency: Yearly or more frequently depending on
fuel type or ash build-up
•By: Qualified Service Technician/Homeowner
The products of combustion will contain small particles
of fly ash. The fly ash will collect in the exhaust venting
system and restrict the flow of the flue gases.
At start-up if there is incomplete combustion, or if there
is a shutdown or incorrect operation of the appliance it
will lead to some soot formation. This will collect in the
exhaust venting system.
The venting system may need to be cleaned at least
once a year or more often depending upon the quality
of your fuel or if there is a lot of horizontal pipe sections. Ash will build up more quickly in the horizontal
sections.
CAUTION
Handle glass assembly with care.
When cleaning glass door:
• Avoid striking, scratching or slamming
glass.
• Do NOT clean glass when hot.
• Do NOT use abrasive cleaners.
• Use a hard water deposit glass cleaner on white film.

•Frequency: At the end of heating season
•By: Homeowner
a. The appliance must be in complete shutdown and
allow the appliance to completely cool down.
b. Remove all ash from the firebox and vacuum thor-
oughly.
c. Paint all exposed steel, including cast-iron. Use
the Touch-Up paint supplied with the appliance or
purchase paint from your local dealer. You must
use a high-temperature paint made specificially for
heating appliances.
D. High Ash Fuel Content Maintenance
•Frequency: When the ash exceeds more than half
way up the firepot.
•By: Homeowner
If the ash build-up exceeds the half way point in the firepot
before it automatically cleans, then the firepot is not being
cleaned often enough.
Another symptom is if clinkers are adhering to the sides
of the firepot.

A. Component Functions
1. Auto-Clean Motor
The auto-clean motor is located under and behind the
firepot on the left side, inside the convection air chamber.
It automatically opens and closes the firepot floor so ashes
can fall into the ash pan.
2. Auto-Clean Switch
The auto-clean switch is located on top of the auto-clean
motor. It communicates to the control board when the firepot
floor is open and when the auto-clean system has completed
its cycle and is back in the home (closed) position.
3. 12 Volt Battery Back-Up Cable
This is an optional accessory. It will plug into the appliance
at the rear of the appliance. An icon will display on the
wall control when the appliance has lost main power and is
running on battery back-up.
4. Combustion (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.
5. Control Board
The control board is located on the lower left side of appliance.
It controls the functioning of the appliance and communicates
with the wall control. The control board can only be opened
by an authorized dealer.
6. Convection Blower
The convection blower is mounted at the bottom left rear of
the appliance. The convection blower pushes heated air
through the heat exchange system into the room.
7. Door Switch
The door switch is mounted on the right side of the firebox
behind the door handle. It senses when the door is open
and will display an icon on the wall control, and will turn off
the auto-clean system and feed motor for safety.
8. Feed System
The feed system is located on the right 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.
R
When describing the location of a component,
it is always AS YOU FACE THE FRONT OF
THE APPLIANCE.
9. Firepot
The firepot is made of high quality ductile iron. The floor of
the firepot automatically opens for cleaning and is operated
by the auto-clean firepot system. The floor needs to return
to a completely closed position or the appliance will not
operate properly.
10. Fuses
There are three fuses. Two fuses are located on the inside
of the control board. One fuse is AC and operates the
igniter and the other fuse is DC and operates all of the
other components. The third fuse is located in the power
supply. A fuse will blow should a short occur and shut off
power to the appliance. The fuses can only be replaced by
an authorized dealer.
11. Heat Exchanger
The heat exchanger is located behind the baffle and it
transfers heat from the exhaust system into the convection
air chamber. Remove the cast iron baffle to access the heat
exchanger.
12. Hopper Lid Switch
The hopper lid switch is located on the right side inside the
hopper. It senses whether the hopper lid is open and displays
an icon on the wall control and will turn off the feed motor.
13. Igniter (Heating Element)
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 or other fuels.
14. Low Fuel Indicator
The low fuel indicator is attached to the left side of the hopper.
It senses the amount of fuel in the hopper and will display
an icon on the wall control.
15. Optical Switch for the Auger
The optical switch is located on top of the feed system and
communicates to the wall control that the auger is spinning
or if it has stopped.
16. Power Receptacle
The power receptacle is located on the lower rear of the
appliance. 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
hightly recommended to protect the electronics.

17. Power Supply
The power supply is located at the rear of the appliance. It
converts 120 volt AC current to 15 volt DC current to power
the appliance.
Overheat Sensor (Snap Disc)
18.
The overheat sensor is mounted on the back of the drop tube in
the center of the appliance and has a 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
sensor will shut the stove down, however the wall control will
still display messages. This sensor must be manually re-set.
Disconnect power before resetting.
19. Thermocouple - Firepot
This thermocouple is located on top of the firepot inside
the thermocouple cover (ceramic protection tube). The
thermocouple sends a millivolt signal to the control board
telling the control board there is a fire in the firepot.
20. Thermocouple - Drop Tube
This thermocouple is located on the bottom of the drop
tube on the right side and attached with a wing nut. It turns
the convection blower on and off, varies the speed of the
convection blower and will shut down appliance if internal
heat exceeds set temperature.
21. Vacuum Switch
The vacuum switch is located on the right side of the
appliance under the feed motor behind right side panel and
connects to the drop tube with a hose. 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.
22. Wall Control
The appliance is designed to run on a custom designed 3.3
volt DC thermostat wall control. It will not operate on any
other wall control. Refer to the instructions supplied with
the thermostat wall control.
