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 hazard by exposing people
or shrubs to high temperatures. The maximum
recommend vertical venting height is 12-feet for
3-inch type “PL” vent. Total length of horizontal
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 backpuf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 certied 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 y ash and to permit periodic
cleaning of the exhaust system. 90-degree elbows
accumulate y ash and soot thereby reducing
exhaust ow 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.

Determining where to install your new pellet stove
heater. To get the most ef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 nd 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

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.
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.

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
anges and roof ashing (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 offset is required, it is better to install 45-degree
elbows rather than 90-degree elbows.

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 ame that is
non-energetic or lazy. If the fuel continues to ow
with too little air for long enough, the burn pot will
ll with too much fuel and the re will smother out.
To much air will result in a ame that is overactive
or aggressive. The ame 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 re will go out. Matching
the amount of air required for proper combustion
to the fuel rate is the primary objective in effectively
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 effectively 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.

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 re. Do
not over re 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 ights, 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 re 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 nes.
•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.

Remove burn pot, making sure it is clean and none
of the air holes are plugged. Clean the rebox, and
then reinstall burn pot. Clean door glass if necessary
(a dry cloth or paper towel is usually sufcient).
Never use abrasive cleaners on the glass or door.
Check fuel in the hopper, and rell 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.
• The damper may need to be closed during
startup.
• DO NOT add pellets to the burn pot by hand.
NOTE: During the rst few res, your stove will
emit an odor as the high-temperature paint cures
or becomes seasoned to the metal. Maintaining
smaller res will minimize this. Avoid placing items
on the stovetop during this period because the paint
could be affected. Attempts to achieve heat output
rates that exceed heater design specications can
result in permanent damage to the heater.
OPTIMAL OPERATION
This pellet stove has been certied 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 1. To achieve a “low burn” your stove
should be set on setting 1.
NOTE: It is possible you may want to use setting
2 for your medium setting. During EPA testing, it
was determined setting 1 achieved a medium burn
rate under laboratory conditions. Settings 3 & 4 will
give you a higher heat output above medium. 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/Off” button to re-start your stove. The stove will
have to fully shut down and turn off before you will
be able to restart the stove.
IGNITOR
1. Fill hopper and clean burn pot.
2. Press the “On/Off” 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 re doesn’t start in 12 minutes, press “On/Off”,
wait a few minutes, clear the burn pot, and start the
procedure again.

with operating instructions in this manual.
SHUTDOWN PROCEDURE
WARNING:
NEVERSHUTDOWNTHISUNITBYUNPLUGGING
IT FROM THE POWER SOURCE.
Turning your stove off 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
rebox 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 off. 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.
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.

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
ue or a newly started re or from a slow-burning
re. As a result, creosote residue accumulates
on the ue lining. When ignited, this creosote
makes an extremely hot re, which may damage
the chimney or even destroy the house. Despite
their high efciency, pellet stoves can accumulate
creosote under certain conditions. The chimney
connector and chimney should be inspected by
a qualied person annually or per ton of pellets
to determine if a creosote or y ash build-up has
occurred. If creosote has accumulated, it should
be removed to reduce the risk of a chimney re.
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 specically designed for the type of chimney
in use. A qualied 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 ow. It should therefore
be periodically removed.
ASH REMOVAL & DISPOSAL
CAUTION:
ALLOW THE STOVE TO COOL BEFORE
PERFORMING 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 tting lid. The closed container of ashes should
be placed on a noncombustible oor or on the
ground, well away from all combustible materials,
pending nal 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 conned 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.
CHECK & CLEAN THE HOPPER
Check the hopper periodically to determine if there
is any sawdust (nes) 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 rst re of the heating season,
check the outside area around the exhaust and air
intake systems for obstructions. Clean and remove
any y 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 owing (this can be done by pressing the “ON”
button with the viewing door open). Vacuum out
the hopper. Thoroughly clean the burn pot, and
rebox. 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.

TROUBLESHOOTING GUIDE
DISPLAY INDICATORS
Several situations or events are indicated in
normal operation by blinking display indicators or
segments in the display:
Flashing On - This means that the stove is in the
“Start Up” state waiting for the ignition procedure
to complete.
Flashing Off - This indicates that the stove is in the
“Shut Down” state waiting for the off button, or for
a 15 minute period after the stove was turned off,
or for the stove to cool down, or for the door to be
closed.
Flashing dash in Heat Range Display - This
indicates that the stove is in the normal run mode
and is ramping from the current heat range setting
to the target heat range setting. Once the ramp is
complete, the dash will stop ashing. For ramping
from heat range 1 to 5, the default time is 12 minutes
(with a 90 second ramp time).
Flashing Automatic Mode - This indicates that
the stove is in normal operation and is running in
the automatic mode. However, either the draft fan
or room fan setting is manually congured.
Flashing Draft Fan Setting - This indicates that the
stove is in normal operation and that the vacuum
sensor detects a loss of pressure either because the
door is open or because there is a negative pressure
in the room with respect to the exhaust.
Flashing Aux - This indicates that the ignitor is on
during the lighting stage.
Quickly (changes twice per second) Flashing
Heat Range Setting - This indicates that the stove
is in normal operation and that an over-temperature
condition exists causing the fuel to stop.
Slowly (changes once per second) Flashing
Heat Range Setting - This indicates that the stove
is in a cut back condition in an attempt to prevent
an over-temperature shut down.
