WARNING! DO NOT INSTALL IN SLEEPING ROOM.
CAUTION! THE STRUCTURAL INTEGRITY OF THE
MOBILE HOME FLOOR, WALL, AND CEILING/ROOF
MUST BE MAINTAINED.
WHEN INSTALLED IN A MOBILE HOME, THE STOVE
MUST BE GROUNDED DIRECTLY TO THE STEEL
CHASSIS AND BOLTED TO THE FLOOR.
In addition to the previously detailed installation
requirements, mobile home installations must meet
the following requirements:
• This stove must be securely fastened to the floor of
the mobile home using two 1/4” lag bolts that are long
enough to go through both a hearth pad, if used, and
the floor of the home.
• The heater must be electrically grounded to the steel
chassis of the mobile home with 8 GA copper wire
using a serrated or star washer to penetrate paint or
protective coating to ensure grounding.
• Vent must be 3 or 4-inch “PL” Vent and must extend
a minimum or 36” (914 mm) above the roof line of the
mobile home and must be installed using a certified
ceiling fire stop and rain cap.
• When moving your mobile home, all exterior venting
must be removed while the mobile home is being
relocated. After relocation, all venting must be
reinstalled and securely fastened.
• Outside Air is mandatory for mobile home installation.
See Outside Air Supply section and your dealer for
purchasing.
• Check with your local building ocials as other codes
may apply.
VENTING REQUIREMENTS
WARNING:
• INSTALL VENT AT CLEARANCES SPECIFIED BY
THE VENT MANUFACTURER.
• DO NOT CONNECT THE PELLET VENT TO A VENT
SERVING ANY OTHER APPLIANCE OR STOVE.
• DO NOT INSTALL A FLUE DAMPER IN THE
EXHAUST VENTING SYSTEM OF THIS UNIT.
The following installation guidelines must be followed
to ensure conformity with both the safety listing of this
stove and to local building codes. Do not use makeshift
methods or compromise in the installation.
IMPORTANT:
THIS UNIT IS EQUIPPED WITH A NEGATIVE DRAFT
SYSTEM THAT PULLS AIR THROUGH THE BURN
POT AND PUSHES THE EXHAUST OUT OF THE
DWELLING. IF THIS UNIT IS CONNECTED TO A FLUE
SYSTEM OTHER THAN THE WAY EXPLAINED IN
THIS MANUAL, IT WILL NOT FUNCTION PROPERLY.
MAXIMUM VENTING DISTANCE
Installation MUST include at least 3-feet of vertical pipe
outside the home. This will create some natural draft to
reduce the possibility of smoke or odor during appliance
shutdown and keep exhaust from causing a nuisance or
hazardbyexposing peopleor shrubs tohigh temperatures.
The maximum recommend vertical venting height is 12-
feet for 3-inch type “PL” vent. Total length of horizontal

-7- © 2021 United States Stove Company
vent must not exceed 4-feet. This could cause back
pressure. Use no more than 180 degrees of elbows (two
90-degree elbows, or two 45-degree and one 90-degree
elbow, etc.) to maintain adequate draft.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors. Too
much draft may cause excessive temperatures in the
appliance. Inadequate draft may cause backpung into
the room and ‘plugging’ of the chimney. Inadequate draft
will cause the appliance to leak smoke into the room
through appliance and chimney connector joints. An
uncontrollable burn or excessive temperature indicates
excessive draft. Take into account the chimney’s location
to ensure it is not too close to neighbours or in a valley
which may cause unhealthy or nuisance conditions.
PELLET VENT TYPE
A certified 3-inch or 4-inch type “PL” pellet vent exhaust
system must be used for installation and attached to the
pipe connector provided on the back of the stove (use a
3-inch to 4-inch adapter for 4-inch pipe). The connection
at the back of the stove must be sealed using Hi-Temp
RTV. Use a 4-inch vent if the vent height is over 12-
feet or if the installation is over 2,500 feet above sea
level. We recommend the use of Simpson Dura-Vent®
or Metal-Fab® pipe (if you use other pipes, consult your
local building codes and/or building inspectors). Do not
use Type-B Gas Vent pipe or galvanized pipe with this
unit. The pellet vent pipe is designed to disassemble for
cleaning and should be checked several times during the
burning season. The pellet vent pipe is not furnished with
the unit and must be purchased separately.
PELLET VENT INSTALLATION
The installation must include a clean-out tee to enable
collection of fly ash and to permit periodic cleaning of the
exhaust system. 90-degree elbows accumulate fly ash
and soot thereby reducing exhaust flow and performance
of the stove. Each elbow or tee reduces draft potential
by 30% to 50%. All joints in the vent system must be
fastened by at least 3 screws, and all joints must be
sealed with Hi-Temp RTV silicone sealant to be airtight.
The area where the vent pipe penetrates to the exterior of
the home must be sealed with silicone or other means to
maintain the vapor barrier between the exterior and the
interior of the home. Vent surfaces can get hot enough
to cause burns if touched by children. Noncombustible
shielding or guards may be required.
PELLET VENT TERMINATION
Do not terminate the vent in an enclosed or semi-enclosed
area, such as; carport, garage, attic, crawl space, under a
sun deck or porch, narrow walkway, or any other location
that can build up a concentration of fumes. Termination
in one of these areas can also lead to unpredictable
pressure situations with the appliance, and could result
in improper performance and/or malfunction. The
termination must exhaust above the outside air inlet
elevation. The termination must not be located where it
will become plugged by snow or other materials. Do not
terminate the venting into an existing steel or masonry
chimney.
VENT TERMINATION CLEARANCES
A. Minimum 4-foot (1.22m) clearance below or beside
any door or window that opens.
B. Minimum 1-foot (0.3m) clearance above any door or
window that opens.
C. Minimum 3-foot (0.91m) clearance from any
adjacent building.
D. Minimum 7-foot (2.13m) clearance from any grade
when adjacent to public walkways.
E. Minimum 2-foot (0.61m) clearance above any grass,
plants, or other combustible materials.

Determining where to install your new pellet stove heater.
To get the most ecient use of re-circulated heat, you
should consider a room that is centrally located within
your home. Choose a room that is large and open. It is
Extremely Important to maintain proper clearances from
any combustible surfaces or materials in the room where
your heater will be located. You can find proper clearance
measurements in this manual and on the rating label of
your pellet stove. The pellet stove can be vented through an
exterior wall or into an existing masonry or metal chimney
if “PL” vent pipe is used throughout existing chimney.
Venting can pass through the ceiling and roof if approved
pipe is used. Where passage through a wall, or partition of
combustible construction is desired, the installation must
conform to CAN/CSA-B365.
WARNING:
• DO NOT OBTAIN COMBUSTION AIR FROM THE
ATTIC, GARAGE OR ANY OTHER UNVENTILATED
AREA. YOU MAY OBTAIN COMBUSTION AIR
FROM A VENTILATED CRAWL SPACE.
• DO NOT INSTALL A FLUE DAMPER IN THE
EXHAUST VENTING SYSTEM OF THIS UNIT.
• DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER HEATER, FURNACE
OR APPLIANCE.
• INSTALL VENT AT CLEARANCES SPECIFIED BY
THE VENT MANUFACTURER.
• ONLY USE APPROVED MATERIAL FOR
INSTALLATION, FAILURE TO DO SO MAY RESULT
IN PROPERTY DAMAGE, BODILY INJURY, OR
EVEN DEATH.
This appliance is certified for use with listed 3 inch or 4 inch
“PL” pellet venting products. The use of other components
other than stated herein could cause bodily harm, heater
damage, and void your warranty.
HORIZONTAL EXHAUST VENT INSTALLATION
1. Locate your pellet stove in a location which meets the
requirements of this manual, but in an area where it
does not interfere with the house framing, wiring, etc.
2. Install a non-combustible hearth pad underneath the
pellet stove. This pad should extend at least 6” (152
mm) in front of the unit.
3. Place the pellet stove approximately 15” (381 mm)
away from the interior wall.
4. Locate the center of the exhaust pipe of your unit. This
point should then be extended to the interior wall of
your house. Once you have located the center point,
on the interior wall, cut a 7” (175 mm) diameter hole
through the wall.
5. The next step is to install the wall thimble, refer to the
instructions which come with the wall thimble for this
step.
6. Install the appropriate length of exhaust vent pipe into
the wall thimble. See steps 11 and 12 when determining
the correct length of exhaust vent to use.
7. Outside Fresh Air is Mandatory when installing
this pellet stove room heater in airtight homes and
mobile homes. Be sure that the outside air vent
has an approved cap on it to prevent rodents from
entering. Be sure to install in location that won’t
become blocked with snow, etc.
8. Connect the exhaust vent pipe to the exhaust outlet of
your pellet stove.
9. Secure all vent joint connections with 3 screws.
Seal the exhaust vent joint connections with high
temperature silicone sealant.
10. Push the unit straight back to the interior wall,
being sure to maintain the minimum clearances to
combustibles 2” (51 mm) to the back of the unit. Seal
the annular space of the wall thimble and around the
vent pipe with high temperature silicone sealant.
11. The exhaust vent pipe must extend at least 12” (300
mm) out past the exterior wall. Seal the annular space
of the wall thimble and around the vent pipe with high
temperature silicone sealant.
12. Install an approved horizontal termination cap or if
necessary install a 90° elbow and appropriate length
of vertical venting. An approved vertical vent cap is
recommended.

INSTALLATION
THROUGH THE WALL INSTALLATION
(RECOMMENDED INSTALLATION)
TYPICAL THROUGH THE
WALL INSTALLATION
Canadian installations must conform to CAN/CSA-B365.
To vent the unit through the wall, connect the pipe
adapter to the exhaust motor adapter. If the exhaust
adapter is at least 18” (457 mm) above ground level, a
straight section of pellet vent pipe can be used through
the wall. Your heater dealer should be able to provide
you with a kit that will handle most of this installation,
which will include a wall thimble that will allow the proper
clearance through a combustible wall. Once outside the
structure, a 3” (76 mm) clearance should be maintained
from the outside wall and a clean out tee should be
placed on the pipe with a 90-degree turn away from the
house. At this point, a 3ft (0.91m) (minimum) section of
pipe should be added with a horizontal cap, which would
complete the installation. A support bracket should be
placed just below the termination cap or one every 4ft
(1.22m) to make the system more stable. If you live in an
area that has heavy snowfall, it is recommended that the
installation be taller than 3ft (0.91m) to get above the
snowdrift line. This same installation can be used if your
heater is below ground level by simply adding the clean-
out section and vertical pipe inside until ground level is
reached. With this installation you have to be aware of the
snowdrift line, dead grass, and leaves. We recommend
a 3ft (0.91m) minimum vertical rise on the inside or
outside of the house. The “through the wall” installation
is the least expensive and simplest installation. Never
terminate the end vent under a deck, in an alcove, under
a window, or between two windows. We recommend
Simpson Dura-Vent® or Metal-Fab® kits.
THROUGH THE ROOF/CEILING INSTALLATION
• When venting the heater through the ceiling, the pipe
is connected the same as through the wall, except the
clean-out tee is always on the inside of the house, and a
3” (76 mm) adapter is added before the clean-out tee.
• You must use the proper ceiling support flanges and
roof flashing (supplied by the pipe manufacturer; follow
the pipe manufacturer’s directions). It is important to
note that if your vertical run of pipe is more than 12ft
(3.7m), the pellet vent pipe size should be increased to
4” (102 mm) in diameter.
• Do not exceed more than 4ft (1.22m) of pipe on a
horizontal run and use as few elbows as possible. If
an oset is required, it is better to install 45-degree
elbows rather than 90-degree elbows.

Buttons :
Heat Range
Room Fan
Draft Fan
Auto Mode
Indicator
Auger Delay
Indicator & Button
O Indicator
& Button
On Indicator
& Button
Your pellet stove utilizes a inclined auger fuel feed
system that is operated by a microprocessor controlled
digital circuit board. The digital circuit board allows the
inclined auger fuel feed system to run in a timer-based,
non-continuous cycle; this cycling allows the auger to
run for a predetermined period of seconds. The auger
pushes pellets up a chute located at the front/bottom of
the hopper which in turn falls through another chute into
the burnpot. Your stove is equipped with an automatic
ignition system that should ignite the fuel within 5-10
minutes from pressing the ON button. As pellets enter
the burn pot and ignite, outside air is drawn across the
fuel and heated during the combustion process which is
then pulled through the heat exchanger by the exhaust
motor or draft fan. As the stove heats up, room air is
circulated around the heat exchanger by means of a room
air blower, distributing warm air into the room.
The amount of heat produced by the stove is proportional
to the rate of the fuel that is burned, and this rate is
controlled by the “HEAT RANGE” setting. In order to
maintain combustion of the fuel at a desired rate, the
air provided to the burn chamber by the exhaust or
draft fan must be maintained precisely. Too little air
will result in a flame that is non-energetic or lazy. If the
fuel continues to flow with too little air for long enough,
the burn pot will fill with too much fuel and the fire will
smother out. To much air will result in a flame that is
overactive or aggressive. The flame in this situation is
typically very blue at the bottom and resembles a blow
torch. If this situation continues, the fuel in the burn pot
will be consumed and the fire will go out. Matching the
amount of air required for proper combustion to the fuel
rate is the primary objective in eectively burning pellets
of various brands and qualities in your stove. The air to
fuel ratio can be adjusted to allow almost any fuel quality
to burn eectively by following the procedures detailed
in the remainder of this manual. Because a forced draft
pressure is required for the combustion process inside
your stove, it is extremely important that the exhaust
system be properly installed and maintained. And, that
when operating your stove, you make sure that the
viewing door is properly sealed.
PANEL/REMOTE CONTROLS
The operation of this appliance can be controlled from
the panel located on the side of the stove and/or by the
remote control. The control functions are as follows:
A. On/O Switch (“Power” Button)
• When pushed, the stove will automatically ignite. No
other fire starter is necessary. The igniter will stay
on for at least 10 and up to 12 minutes, depending on
when Proof of Fire is reached. The fire should start in
approximately 5 minutes.
• After pushing “POWER”, the auger motor is on for 3.5
minutes, o for 1 minute. During the remainder of the
start-up period, the auger motor operates on the heat
range “1” setting.
• During start up the heat level advance (Up and Down
keys) will change the heat range indicator level
accordingly, but there is no change in the stoves
operating conditions until start-up is completed.

When using the hand-held remote this function can be
performed with the “Up/Down” buttons.
• The levels of heat output will incrementally change on
the bar graph starting from heat range “1” to heat range
“5”.
CONTROL PANEL OVERVIEW
Turning the heater ON/OFF, as well as adjustments for
the fuel feed rate and room fan speed are performed by
pressing the appropriate button(s) on the control panel
which is located on the lower left-hand side of your heater.
• ON/OFF
Pressing the “ON” button on the control panel will begin
the start-up sequence for the heater. Fuel will begin to
feed through the auger feed system then ignite after
approximately 5 minutes.
Pressing the “OFF” button on the control panel will cause
the heater to enter its shut-down sequence. The fuel feed
system will stop pulling fuel from the hopper and, once
the fire goes out and the heater cools down, the fans will
stop running.
• HEAT RANGE
Pressing the “Heat Range” arrows, up or down, will adjust
the amount of fuel being delivered to the burnpot.
• DRAFT FAN
The draft fan (exhaust) will come on as soon as the “ON”
button is pressed. The fan will automatically adjust its
speed in accordance to the heat range setting. However,
this speed can be manually operated by pressing the
“Draft Fan” arrows up or down. “Draft Fan” when pressed,
the display will show “Df-A”, which is automatic. Press
the arrows again to adjust fan speed. When the heater

THERMOSTAT HOOK-UP
1. Put female terminals on the lead wires to
your low voltage thermostat.
2. Plug one thermostat lead onto each of the
terminal posts on the circuit board.
The Jumper Must
Be Removed First
Use 18 gauge, 2
conductor wire
IMPORTANT NOTE: The purpose of the T’Stat is
to make the stove cycle between the
preselected desired heat range setting (”1” to
“5”) and the minimum heat range setting of “1”.
The T’Stat will not turn the stove on and off.
When the desired room temperature has been
reached and the T’Stat no longer requires heat
it will reduce to a minimum heat range setting of
“1”. The unit will not turn completely off. Once
the room temperature has dropped and the
T’Stat requires more heat, the unit will begin to
feed pellets at the preselected heat setting
ranging from “1” to “5”.

10. Salt water driftwood or other previously salt water
saturated materials;
11. Unseasoned wood; or
12. Paper products, cardboard, plywood, or particleboard.
The prohibition against burning these materials does
not prohibit the use of fire starters made from paper,
cardboard, saw dust, wax and similar substances
for the purpose of starting a fire in an aected wood
heater.
Burning these materials may result in release of toxic
fumes or render the heater ineective and cause smoke.
PROPER FUEL
ATTENTION:
THIS APPLIANCE IS DESIGNED FOR THE USE OF
PELLETIZED FUEL THAT MEET OR EXCEED THE
STANDARD SET BY THE PELLET FUEL INSTITUTE
(PFI).
Your pellet stove is designed to burn premium hardwood
pellets that comply with the Pellet Fuels Institute (PFI)
standard (minimum of 40 lbs density per cubic ft, 1/4” to
5/16” diameter, length no greater than 1.5”, not less than
8,200 BTU/lb, moisture under 8% by weight, ash under
1% by weight, and salt under 300 parts per million).
Pellets that are soft, contain excessive amounts of loose
sawdust, have been, or are wet, will result in reduced
performance. Store your pellets in a dry place. DO NOT
store the fuel within the installation clearances of the
unit or within the space required for refuelling and ash
removal. Doing so could result in a house fire. Do not over
fire or use volatile fuels or combustibles, doing so may
cause a personal and property damage hazards.
THIS STOVE IS APPROVED FOR BURNING PELLETIZED
WOOD FUEL ONLY ! Factory-approved pellets are those
1/4” or 5/16” in diameter and not over 1” long. Longer or
thicker pellets sometimes bridge the auger flights, which
prevents proper pellet feed. Burning wood in forms other
than pellets is not permitted. It will violate the building
codes for which the stove has been approved and will
void all warranties. The design incorporates automatic
feed of the pellet fuel into the fire at a carefully prescribed
rate. Any additional fuel introduced by hand will not
increase heat output but may seriously impair the stoves
performance by generating considerable smoke. Do
not burn wet pellets. The stove’s performance depends
heavily on the quality of your pellet fuel. Avoid pellet
brands that display these characteristics:
• Excess Fines – “Fines” is a term describing crushed
pellets or loose material that looks like sawdust or sand.
Pellets can be screened before being placed in hopper
to remove most fines.
• Binders – Some pellets are produced with materials to
hold the together, or “bind” them.
• High ash content – Poor quality pellets will often create
smoke and dirty glass. They will create a need for more
frequent maintenance. You will have to empty the burn
pot plus vacuum the entire system more often. Poor
quality pellets could damage the auger. We cannot
accept responsibility for damage due to poor quality
pellet.
CAUTION:
• KEEP FOREIGN OBJECTS OUT OF THE HOPPER.
• THE MOVING PARTS OF THIS STOVE ARE
PROPELLED BY HIGH TORQUE ELECTRIC
MOTORS. KEEP ALL BODY PARTS AWAY FROM
THE AUGER WHILE THE STOVE IS PLUGGED
INTO AN ELECTRICAL OUTLET. THESE MOVING
PARTS MAY BEGIN TO MOVE AT ANY TIME
WHILE THE STOVE IS PLUGGED IN.

PRE-START-UP CHECK
Remove burn pot, making sure it is clean and none of the
air holes are plugged. Clean the firebox, and then reinstall
burn pot. Clean door glass if necessary (a dry cloth or
paper towel is usually sucient). Never use abrasive
cleaners on the glass or door. Check fuel in the hopper,
and refill if necessary.
BUILDING A FIRE
Never use a grate or other means of supporting the fuel.
Use only the burn pot supplied with this heater. Hopper
lid must be closed in order for the unit to feed pellets.
During the start-up period:
• Make sure the burn pot is free of pellets.
• DO NOT open the viewing door.
• DO NOT add pellets to the burn pot by hand.
NOTE: During the first few fires, your stove will emit an
odor as the high-temperature paint cures or becomes
seasoned to the metal. Maintaining smaller fires will
minimize this. Avoid placing items on the stovetop during
this period because the paint could be aected. Attempts
to achieve heat output rates that exceed heater design
specifications can result in permanent damage to the
heater.
OPTIMAL OPERATION
This pellet stove has been certified by the US EPA to
meet strict 2020 guidelines. To Insure this unit produces
the optimal minimal emissions, it is critical to follow the
following guidelines. To achieve a “high burn” your stove
should be set on setting 5. To achieve a “medium burn”
your stove should be set on setting 2. To achieve a “low
burn” your stove should be set on setting 1. Settings 3 &
4 will give you a higher heat output above medium burn
rate. If the door is opened while the stove is in operation
it must be closed within 30 seconds or the stove will shut
down. If the stove shuts down push the “On/O” button
to re-start your stove. The stove will have to fully shut
down and turn o before you will be able to restart the
stove.
IGNITOR
1. Fill hopper and clean burn pot.
2. Press the “On/O” button. Make sure the green light
comes on.
3. Adjust the feed rate to the desired setting by pressing
the “Heat Level Advance” button.
If the fire doesn’t start in 12 minutes, press “On/O”, wait
a few minutes, clear the burn pot, and start the procedure
again.
OPENING DOOR
CAUTION:
• DO NOT OPERATE YOUR STOVE WITH THE
VIEWING DOOR OPEN. THE AUGER WILL NOT
FEEDPELLETSUNDERTHESECIRCUMSTANCES
AND A SAFETY CONCERN MAY ARISE FROM
SPARKS OR FUMES ENTERING THE ROOM.
• THE DOOR MUST BE CLOSED AND SEALED
DURING OPERATION.
If the door is opened while the stove is in operation it
must be closed within 30 seconds or the stove will shut
down. If the stove shuts down push the “On/O” button
to re-start your stove. The stove will have to fully shut
down and turn o before you will be able to restart the
stove.
ROOM AIR FAN
When starting your stove the Room Air Fan will not
come on until the stove’s heat exchanger warms up. This
usually takes about 10 minutes from start-up.
IF STOVE RUNS OUT OF PELLETS
The fire goes out and the auger motor and blowers will
run until the stove cools. This will take 30 minutes or
longer depending on the heat remaining in the appliance.
After the stove components stop running all lights on
the display will go out and the two digit display will begin
flashing “E3”

TAMPER WARNING
This wood heater has a manufacturer-set minimum low
burn rate that must not be altered. It is against federal
regulations to alter this setting or otherwise operate this
wood heater in a manner inconsistent with operating
instructions in this manual.
SHUTDOWN PROCEDURE
WARNING:
NEVER SHUT DOWN THIS UNIT BY UNPLUGGING
IT FROM THE POWER SOURCE.
Turning your stove o is a matter of pressing the “POWER”
button on the display board. The green light will turn back
to red when the “POWER” button is pushed. The auger
motor will stop, and the blowers will continue to operate
until the internal firebox temperatures have fallen to a
preset level.
1. Your stove is equipped with a high temperature
thermodisc. This unit has a manual reset thermodisc.
This safety switch has two functions.
A. To recognize an overheat situation in the stove and
shut down the fuel feed or auger system.
B. In case of a malfunctioning convection blower, the
high-temperature thermodisc will automatically shut
down the auger, preventing the stove from overheating.
NOTE: On some units, once tripped, like a circuit breaker,
the reset button will have to be pushed before restarting
your stove. On other units the thermodisc has no reset
button and will reset itself once the stove has cooled. The
manufacturer recommends that you call your dealer if this
occurs as this may indicate a more serious problem. A
service call may be required.
2. If the combustion blower fails, an air pressure switch
will automatically shut down the auger.
NOTE: Opening the stove door for more than 30 seconds
during operation will cause enough pressure change to
activate the air switch, shutting the fuel feed o. The stove
will shut down and show “E2” on the two digit display. The
stove has to fully shut down before restarting.
INTERIOR CHAMBERS
• Burn Pot - Periodically remove and clean the burn pot
and the area inside the burn pot housing. In particular,
it is advisable to clean out the holes in the burn pot to
remove any build up that may prevent air from moving
through the burn pot freely.
• Heat Exchanger - There are two clean out plates that
need to be removed in order to clean the fly ash out
of the heat exchanger. Open the door to access the
cleanouts located inside the firebox, one on each side of
the burnpot. The clean outs are secured to the firebox
with (2) 5/16” screws each. Remove the clean outs
and vacuum out any accumulated ash. This should be
done at least once per month or more frequently if large
amounts of ash are noticed while cleaning or if the stove
does not seem to be burning properly.
Over time ash or dust may accumulate on the blades of the
circulation & exhaust fans. The fans should be inspected,
periodically, and if any accumulation is present vacuumed
clean as the ash or dust can impede the fans performance.
It is also possible that creosote may accumulate in the
exhaust fan therefore, this must be brushed clean. The
exhaust fan can be found behind the left side panel (facing
the front of the heater), the circulation fan can be found
behind the right side panel. To access the igniter, remove
the air inlet tube and cover (2 screws). The auger motor is
located in the center rear of the unit. Note: When cleaning,
take care not to damage the fan blades.
If a vacuum is used to clean your stove, we suggest using
the AV15E AshVac vacuum. The AV15E AshVac is designed
for ash removal. Some regular vacuum cleaner (i.e. shop
vacs) may leak ash into the room.
DO NOT VACUUM HOT ASH.

CREOSOTE FORMATION, INSPECTION, &
REMOVAL
CAUTION:
THE EXHAUST SYSTEM SHOULD BE CHECKED
MONTHLY DURING THE BURNING SEASON FOR
ANY BUILD-UP OF SOOT OR CREOSOTE.
When any wood is burned slowly, it produces tar and
other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense
in the relatively cool chimney flue or a newly started
fire or from a slow-burning fire. As a result, creosote
residue accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire, which may damage
the chimney or even destroy the house. Despite their high
eciency, pellet stoves can accumulate creosote under
certain conditions. The chimney connector and chimney
should be inspected by a qualified person annually or per
ton of pellets to determine if a creosote or fly ash build-
up has occurred. If creosote has accumulated, it should
be removed to reduce the risk of a chimney fire. Inspect
the system at the stove connection and at the chimney
top. Cooler surfaces tend to build creosote deposits
quicker, so it is important to check the chimney from
the top as well as from the bottom. The creosote should
be removed with a brush specifically designed for the
type of chimney in use. A qualified chimney sweep can
perform this service. It is also recommended that before
each heating season the entire system be professionally
inspected, cleaned and, if necessary, repaired. To clean
the chimney, disconnect the vent from the stove.
FLY ASH
This accumulates in the horizontal portion of an exhaust
run. Though non-combustible, it may impede the normal
exhaust flow. It should therefore be periodically removed.
ASH REMOVAL & DISPOSAL
CAUTION:
ALLOWTHESTOVETOCOOLBEFOREPERFORMING
ANY MAINTENANCE OR CLEANING. ASHES
MUST BE DISPOSED IN A METAL CONTAINER
WITH A TIGHT FITTING LID. THE CLOSED
CONTAINER OF ASHES SHOULD BE PLACED ON
A NON-COMBUSTIBLE SURFACE OR ON THE
GROUND, WELL AWAY FROM ALL COMBUSTIBLE
MATERIALS, PENDING FINAL DISPOSAL.
Remove the ashes periodically to avoid unnecessary ash
build up. Remove ashes when unit has cooled. Ashes
should be placed in a metal container with a tight fitting
lid. The closed container of ashes should be placed on a
noncombustible 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 embers have been thoroughly cooled.
The container shall not be used for other trash or waste
disposal. If combined with combustible substances,
ashes and embers may ignite.
SMOKE & CO MONITORS
Burning wood naturally produces smoke and carbon
monoxide(CO) emissions. CO is a poisonous gas when
exposed to elevated concentrations for extended
periods of time. While the modern combustion systems
in heaters drastically reduce the amount of CO emitted
out the chimney, exposure to the gases in closed or
confined areas can be dangerous. Make sure you stove
gaskets and chimney joints are in good working order
and sealing properly to ensure unintended exposure. It is
recommended that you use both smoke and CO monitors
in areas having the potential to generate CO.

MAINTENANCE
CHECK & CLEAN THE HOPPER
Check the hopper periodically to determine if there is any
sawdust (fines) that is building up in the feed system or
pellets that are sticking to the hopper surface. Clean as
needed.
DOOR & GLASS GASKETS
Inspect the main door and glass window gaskets
periodically. The main door may need to be removed to
have frayed, broken, or compacted gaskets replaced
by your authorized dealer. This unit’s door uses a 3/4”
diameter rope gasket.
BLOWER MOTORS
Clean the air holes on the motors of both the exhaust
and distribution blowers annually. Remove the exhaust
blower from the exhaust duct and clean out the internal
fan blades as part of your fall start-up. If you have indoor
pets your power motors should be inspected monthly to
make sure they are free of animal hair build up. Animal
hair build up in blowers can result in poor performance or
unforeseen safety hazards.
PAINTED SURFACES
Painted surfaces may be wiped down with a damp cloth.
If scratches appear, or you wish to renew your paint,
contact your authorized dealer to obtain a can of suitable
high-temperature paint.
GLASS
We recommend using a high-quality glass cleaner. Should
a buildup of creosote or carbon accumulate, you may wish
to use 000 steel wool and water to clean the glass. DO
NOT use abrasive cleaners. DO NOT perform the cleaning
while the glass is HOT. Do not attempt to operate the unit
with broken glass. Replacement glass may be purchased
from your U.S. Stove dealer. If the glass is broken, follow
these removal procedures:
1. Once the heater has cooled, remove the door from
the heater.
2. Remove the rope gasket from the door followed by
the nuts holding the glass retainer in place.
3. While wearing gloves, carefully remove any loose
pieces of glass from the door frame.
4. Replace the glass and gasket, making sure the gasket
runs the full perimeter of the glass edge.
5. Re-install the retainer and eight nuts and rope gasket
using high-temperature silicone to adhere the gasket
to the door.
6. Never use substitute materials for the glass.
DO NOT abuse the door glass by striking, slamming, or
similar trauma. Do not operate the stove with the glass
removed, cracked, or broken.
FALL START UP
Prior to starting the first fire of the heating season,
check the outside area around the exhaust and air intake
systems for obstructions. Clean and remove any fly ash
from the exhaust venting system. Clean any screens on
the exhaust system and on the outside air intake pipe.
Turn all of the controls on and make sure that they are
working properly. This is also a good time to give the
entire stove a good cleaning throughout.
SPRING SHUTDOWN
After the last burn in the spring, remove any remaining
pellets from the hopper and the auger feed system. Scoop
out the pellets and then run the auger until the hopper
is empty and pellets stop flowing (this can be done by
pressing the “ON” button with the viewing door open).
Vacuum out the hopper. Thoroughly clean the burn pot,
and firebox. It may be desirable to spray the inside of the
cleaned hopper with an aerosol silicone spray if your stove
is in a high humidity area. The exhaust system should be
thoroughly cleaned.
