OUTSIDE AIR SUPPLY
Adequate ventilation air is required to operate this
heater. During operation, the heater draws air for
combustion which can be assisted by the installation of
outside combustion air inlets. However, certain weather
conditions such as icing or use of kitchen exhaust fans
may impact and reduce the eectiveness of vents. It is
important to note that room air starvation will negatively
impact the operation of the heater. Depending on
your location and home construction, outside air may
be necessary for optimal performance. Your stove is
approved to be installed with an outside air intake (4FAK)
which is necessary for a mobile home. You can purchase
the 4FAK through your heater dealer. Installation
instructions are supplied with the air intake kit. Below
is a list of possible indicators that a source of outside
combustion air may be required.
• Your stove does not draw steadily, smoke rollout occurs,
wood burns poorly, or back-drafts occur whether or not
there is combustion present.
• Existing fuel-fired equipment in the house, such as
fireplaces or other heating appliances, smell, do not
operate properly, suer smoke roll-out when opened, or
back-drafts occur whether or not there is combustion
present.
• Opening a window slightly on a calm (windless) day
alleviates any of the above symptoms.
• The house is equipped with a well-sealed vapor barrier
and tight fitting windows and/or has any powered
devices that exhaust house air.
• There is excessive condensation on windows in the
winter.
• A ventilation system is installed in the house.
ATTENTION:
DO NOT VENT UNDER ANY PORCH, DECK,
AWNING, OR IN ANY SEMI ENCLOSED OR
ROOFED AREA. DOING SO MAY RESULT IN
UNPREDICTABLE AIRFLOW AT THE VENT CAP
UNDER CERTAIN CONDITIONS AND CAN AFFECT
THE PERFORMANCE OF YOUR STOVE, AS WELL
AS, OTHER UNFORESEEABLE ISSUES.
WARNING:
DO NOT CONNECT TO OR USE IN CONJUNCTION
WITH ANY AIR DISTRIBUTION DUCT WORK
UNLESS SPECIFICALLY APPROVED FOR SUCH
INSTALLATION.
Taller or longer chimney system’s may need a barometric
damper installed immediately o the top of the stove
to be able to control the stove down in the 400° range
as you can experience excessive draft and the stove will
want to run hotter.
This stove is mobile home approved (U.S.ONLY). Mobile
homes require outside air, use a vent with a rigid or flex
pipe connected to the stove, and an outside screen vent
cap. The stove must be secured to the floor, and grounded
with a number 8 gauge wire. Mobile home installation
should be done in accordance with the Manufactured
Home and Safety Standard (HUD), CFR 3280, Part 24.
Only approved pellet vent can be used. The chimney
installation must allow for removal in case of mobile
home transportation, especially outside connections.
You may contact your local building authority or person
having jurisdiction on height restrictions.

SECURING APPLIANCE TO THE FLOOR
Securely fasten this stove to the floor by screwing 1/4”
lag bolts up through the floor into the leg leveling holes.
WARNING! DO NOT INSTALL IN SLEEPING ROOM.
CAUTION! THE STRUCTURAL INTEGRITY OF THE
MOBILE HOME FLOOR, WALL, AND CEILING/
ROOF MUST BE MAINTAINED. MAINTAIN AN
EFFECTIVE VAPOR BARRIER BY SEALING WITH
SILICONE WHERE THE CHIMNEY OR OTHER
COMPONENTS PENETRATE TO THE EXTERIOR OF
THE STRUCTURE.
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:
• All installations must meet local codes.
• Install option 1: Use 3”-4” listed L vent pellet pipe -or-
Install option 2: Use 4”, 5”, or 6” class A 103 HT chimney
system. Note: Do not mix use of chimney systems
during installation. Use 1 system type throughout the
installation.
• Use a minimum of 24 gauge, 4” or larger connector pipe
with the class A 103 HT chimney system (install option
2).
• This is a wood stove that burns wood pellet fuel. This
means natural draft is running the stove. It must be
treated as a wood stove with the pipe installation being
as vertical as possible to obtain maximum upward
draft.
• Horizontal runs and elbows are discouraged.
• Do not install a manual flue damper in the exhaust vent.
Install vent at clearances specified by the vent
manufacturer. The chimney connector shall not pass
through an attic or roof space, closet or similar concealed
space, or floor, or ceiling. Where passage through a wall
or partition of combustible construction is desired, the
installation shall conform to CAN/CSA-B365, US-L
vent installation code for solid fuel burning appliances
and equipment. Exhaust vent required for residential
installation or mobile home installation (US only) is a
listed type “PL” venting - 3” or 4” (76 mm or 102 mm)
diameter. If installed into a tightly constructed home,
(Mobile Home) a fresh air opening of at least 2” (150
mm) diameter into the room where the unit is installed
is required.
WARNING:
DO NOT COMPROMISE INSTRUCTIONS FOR
INSTALLATION OR MAKE CHANGES TO
MANUFACTURERS SPECIFICATIONS DURING THE
INSTALLATION OF THIS PRODUCT.
Attach and secure the exhaust venting system to the
product and to each adjoining section. All joints for
connector pipe shall be required to be fastened with
at least three screws. 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.
Noncombustible shielding or guards may be required.
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 back pu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 neighbors or in a valley
which may cause unhealthy or nuisance conditions.
STOVE PIPE INSTALLATION
This stove has no need for electricity, it operates with
a natural draft. The strength of the draft is determined
by the height of its chimney, and that’s why the chimney
installation is the determining factor on how well this
stove will perform. This stove will operate best with a
straight chimney either 3” diameter or 4” diameter with
8ft to 12ft overall height, although it will operate with
many variance’s of chimney height and configurations,
they will all bring varied results in burn time and fuel
usage.A straightchimney isalwaysthe bestconfiguration
for this pellet stove. Do not make changes to the draft
recommendations during the installation of the chimney
orstove.Thisisastovethatburnspelletfuel,ifanadequate
draft is not accomplished this stove will not operate
properly and can potentially cause smoke to come from
the stove. If the draft is compromised, it can drastically
impede the performance of the stove, especially when
using hardwood pellet fuel. Long horizontal chimney runs
will impede the draft and cause poor performance of this
stove.

Install option one: When 8ft to 15ft length of venting is
used, utilize 3” diameter listed L vent pellet pipe. When
having to use more than 15ft of venting, then utilize a 4”
diameter listed L vent pellet pipe. In some installations
and because of outside environmental conditions, a
barometric damper may need to be installed immediately
o the top of the stove. This barometric damper will
prevent excessive draft which causes your stove to burn
hotter than normal and burn excessive fuel. You can also
adjust the bars closer together on the burn basket to
lower the temperature if it starts running too hot. See the
“Tuning Your Stove” section of this manual.
A 4” diameter listed L vent pellet pipe is recommended
if you decide to go through the wall, and you need to
terminate above the roof at least 24” using pellet vent.
When installing into an existing chimney, then you must
run 4” vent all the way up any existing chimney and
terminating at the top.
Install option two: Use minimum 24 gauge single wall
pipe in 4”, 5” or 6” diameter when connecting to listed
factorybuiltchimney.Usea3”-4”,3”-5”or3”-6”increaser
directly o the stove then connect to the required length
of pipe to reach the factory built chimney. A slip joint can
be used to allow connection to the factory built chimney
or a plug can be inserted at the entry point of the factory
built chimney. The connector pipe shall pass through
the plug a minimum of 4” or can pass through the entire
length of the chimney. When using this method install
another properly sized plug at the top of the chimney and
continue connector pipe out and above the plug at least
2”. Install proper sized cap or in the event factory built
cap is already in place with spark arrester, the connector
pipe can be terminated under the existing factory built
cap. When installing your stove, an all vertical stove pipe,
straight up and through the roof is best. This will ensure
a good upward draft that all stoves need to operate. The
more twists and turns you have in stove piping the more
it will restrict the draft. This is true for all stoves.

Method B. 9” (229 mm) Clearance to Combustible Wall
Member: Using a 6” (153 mm) inside diameter, listed,
factory-built Solid-Pak chimney section with insulation
of 1” (26 mm) or more, build a wall pass-through with a
minimum 9” (229 mm) air space between the outer wall
of the chimney length and wall combustibles. Use sheet
metal supports fastened securely to wall surfaces on
all sides, to maintain the 9” (229 mm) air space. When
fastening supports to chimney length, do not penetrate
the chimney liner (the inside wall of the Solid-Pak
chimney). The inner end of the Solid-Pak chimney section
shall be flush with the inside of the code-approved
masonry chimney with a flue liner flue, and sealed with a
non-water soluble refractory cement. Use this cement to
also seal to the brick masonry penetration.
Method C. 6” (153 mm) Clearance to Combustible Wall
Member: Starting with a minimum 24 gauge (.024”
[.61 mm]) 6” (153 mm) metal chimney connector, and
a minimum 24 gauge ventilated wall thimble which has
two air channels of 1” (26 mm) each, construct a wall
pass-through. There shall be a minimum 6” (153 mm)
separation area containing fiberglass insulation, from the
outer surface of the wall thimble to wall combustibles.
Support the wall thimble, and cover its opening with a
24-gauge minimum sheet metal support. Maintain the
6” (153 mm) space. There should also be a support sized
to fit and hold the metal chimney connector. See that
the supports are fastened securely to wall surfaces on
all sides. Make sure fasteners used to secure the metal
chimney connector do not penetrate chimney flue liner.
Method D. 2” (51 mm) Clearance to Combustible Wall
Member: Start with a solid-pak listed factory built
chimney section at least 12” (304 mm) long, with
insulation of 1” (26 mm) or more, and an inside diameter
of 8” (2 inches [51 mm] larger than the 6” [153 mm]
chimney connector). Use this as a pass-through for a
minimum 24-gauge single wall steel chimney connector.
Keep solid-pak section concentric with and spaced 1” (26
mm) o the chimney connector by way of sheet metal
support plates at both ends of chimney section. Cover
opening with and support chimney section on both sides
with 24 gauge minimum sheet metal supports. See that
the supports are fastened securely to wall surfaces on all
sides. Make sure fasteners used to secure chimney flue
do not penetrate flue liner.
NOTES: Connectors to a code-approved masonry
chimney with a flue liner, excepting method B, shall
extend in one continuous section through the wall pass-
through system and the chimney wall, to but not past the
inner flue liner face. A chimney connector shall not pass
through an attic or roof space, closet or similar concealed
space, or a floor, or ceiling.

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 charging 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. 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.
CAUTION:
• KEEP FOREIGN OBJECTS OUT OF THE HOPPER.
• DO NOT BLOCK THE FRESH AIR INTAKE
PORTS – THIS WILL SERIOUSLY AFFECT THE
PERFORMANCE OF THE STOVE.
NEVER OPERATE THIS PRODUCT WHILE UNATTENDED

CAN RESULT IN PERMANENT DAMAGE TO THE
HEATER.
LIGHTING WITH A HANDHELD PROPANE
TORCH
You will need a handheld propane torch to ignite your
stove. We recommend a high quality torch with a squeeze
trigger ignition system.
1. Make sure the pellet feed door is in the closed
position, this is the external knob located on the front
of the hopper. All the way down indicates closed.
2. Remove hopper lid and add desired amount of pellets.
3. Make sure front damper slide is in the closed position,
holes should be blocked.
4. Inspect primary burn chamber, secondary burn plate
and ashtray for soot build up and cleanliness. Perform
any maintenance required.
5. Reinstall primary burn chamber, secondary burn
plate and ashtray.
6. Remove the primary chamber end slide (the top
handle).
7. Light the torch and insert into primary burn chamber.
Let the torch run for approximately one minute. This
will start the necessary draft and speed the ignition
process.
8. Slide the feed to the all the way open position (the
knob should now be at the top of the slot).
9. Let the torch run till the stove reaches 200 degrees
(this should only take approximately 5 minutes
depending on the type of fuel).
10. Remove, turn o and store your torch.
11. Keep the primary slide cover o until the stove
reaches approximately 400°F.
WARNING:
AFTER STARTING THE STOVE THE PRIMARY END

6. Turn heat gun down to the low setting and continue
to run until the stove reaches 400 degrees, this will
happen rapidly after ignition of the pellets.
7. Remove, turn o and store your heat gun.
8. Reinstall the primary chamber end slide.
CONTROLLING THE TEMPERATURE
OPEN
Because the damper slide is located behind the
combustion chamber, adjusting the temperature is
the opposite of a traditional wood stove. To adjust the
damper slide: turn handle counter clockwise one half turn
then slide to the desired position and retighten. The open
position will reduce the draft and slow the stove down
much like a crack in a drinking straw. Closing the damper
will increase higher temperatures and heat output.
CAUTION:
DO NOT OVER LOOSEN THE DAMPER SLIDE
HANDLE! THIS MAY CAUSE THE HANDLE TO
SEPARATE FROM THE DAMPER PLATE.
TUNING YOUR STOVE
After your stove is installed and ready for use there will
be a period of time where some adjustments may be
necessary to fit your specific needs from the stove. We
like to refer to this as “getting to know your stove”. Each
stove demonstrates its own unique personality based
upon; type of pellet fuel, elevation, square footage you are
heating, barometric pressures, common wind currents,
naturaldraftswithinyourhometonameafew.Specifically
this means learning how often you will need to dump
ashes, clear the secondary burn plate, experiment with
dierent brand pellets and determining what position the
damper slide needs to be in to get your specific desired
results. After you have become familiar with the stove
it is possible that you may need to adjust the primary
burn basket. The primary burn basket that comes with
every stove is sent out at a preset measurement. This
measurement fits most applications but sometimes a
user will need to make an adjustment. This is simple to
perform; we find the best tools for widening the basket
are two chisels. For narrowing the spacing use a pair of
pliers. The three black arrows indicate the three spaces
where pellets drop through the basket and on to the
secondary burn plate. The minimum spacing should not
be adjusted to less than 0.290, or on a tape measure the
closest mark would be just under the 19/64”mark.
The maximum adjustment should not exceed 0.320, or
just over the 5/16” mark on a tape measure. Only make
small adjustments at a time as you will discover a small

adjustment can result in a drastic temperature change.
Narrowing will slow the pellet feed rate resulting in lower
running temperature. Widening will result in an increased
pellet feed rate resulting in a higher running temperature.
HELPFUL HINTS
• Starting the draft by letting the handheld torch run
for one minute before introducing pellets is highly
recommended. When the stove is cold and it is colder
outside than it is inside, there is a downward draft in
the chimney. Running the torch for one minute first will
overcome this downward draft that is present.
• If smoke becomes present during ignition, reposition
the torch head so the flame is burning across the
bottom of the burn basket not directly on it.
• The secondary burn plate can be slid out up to one inch
to provide maximum airflow during operation.
• While operating the stove on low (damper holes open)
the temperature gauge should never fall below 300°.
Two things happen when the stove falls below 300°.
1) The draft will slow down enough to impede the
performance of the stove. 2) Creosote will build up
causing poor performance and increase the risk of a
flue fire.
• If it was necessary to adjust the primary burn basket
wider, it may be necessary to clear the secondary burn
plate more often during operation.
• A barometric damper will help solve problems when
the stove is experiencing constant high heat output.
Barometric gives the user the ability to regulate draft
through the chimney until desired temperatures are
established on the appliance it has been installed on.
• A VacuStack chimney cap is recommended when
experiencing draft issues or fluctuating temperatures
or low heat output. VacuStack caps are designed to
increase draft on any chimney by causing a vacuum
eect through the flue below when the air moves past
the cap.
• CAUTION: In high wind areas, excessive draft can be
experienced resulting in extended high-temperature
output on the stove. We recommend a barometric
damper be installed when this occurs which gives you
the ability to control the excessive draft created by the
vacustack and persistent wind currents above.
• Remedies for those that experience a temperature
drop after several hours of operation: First, dump the
ashtray and properly dispose of ashes as described in
this manual. Second, clear the secondary burn plate
as described in this manual. If this does not bring the
temperature back up then close the pellet stop plate for
approximately 35 minutes running the stove on high.
Reopen the pellet stop plate. This clears the vertical
feed tube of any pre-heated pellets and reintroduces
fresh pellet fuel.
REFUELLING
CAUTION:
• THE HOPPER AND STOVE WILL BE HOT
DURING OPERATION; THEREFORE, YOU
SHOULD ALWAYS USE SOME TYPE OF HAND
PROTECTION WHEN REFUELING YOUR STOVE.
• DO NOT TOUCH THE HOT SURFACES OF THE
STOVE. EDUCATE ALL CHILDREN ON THE
DANGERS OF A HIGH-TEMPERATURE STOVE.
YOUNG CHILDREN SHOULD BE SUPERVISED
WHEN THEY ARE IN THE SAME ROOM AS THE
STOVE.
• WE RECOMMEND THAT YOU NOT LET THE
HOPPER DROP BELOW 1/4 FULL.
WARNING:
• KEEP HOPPER LID CLOSED AT ALL TIMES
EXCEPT WHEN REFILLING.
• DO NOT OVERFILL HOPPER.
TAMPER WARNING
This wood heater has a manufacturer-set minimum
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.
SHUTTING DOWN THE STOVE
When you are ready to shut your stove down simply
close the pellet feed door (move to the down position).
After you have closed the pellet feed door the stove will
continue to run for approximately 45 minutes. When
shutting down the stove make sure to close the draft slide
(holes blocked).

MAINTENANCE
CAUTION:
• FAILURE TO CLEAN AND MAINTAIN THIS
UNIT AS INDICATED CAN RESULT IN POOR
PERFORMANCE, SAFETY HAZARDS, FIRE, AND
EVEN DEATH.
• NEVER PERFORM ANY INSPECTIONS,
CLEANING, OR MAINTENANCE ON A HOT
STOVE.
• DONOTOPERATE STOVEWITHBROKENGLASS,
LEAKAGE OF FLUE GAS MAY RESULT.
CLEANING
Learn your stove! This stove has no moving parts and
requires no electricity; it does however require your
attention muchlike a wood stove, especially when burning
a hardwood pellet. It is very important to thoroughly clean
the fly ash out of this unit weekly. The window will need
to be remove to properly clean the fly ash out of the unit.
Steps for removing the fly ash are as listed:
1. Allow the unit to cool completely. Remove the 5/16”
diameter pin on the right side of the window as shown
2. Lift up on the window frame to disengage the left side
of the window as shown. Note: When removing the
window be very careful to hold both the glass and the
frame.
3. Vacuum the cooled ash out of the unit. Be sure to
vacuum both upstream and downstream of the
window opening. Note: All vacuuming must be
performed using an ash vac.
4. Remove the burn pot and vacuum out the burn pot
chamber.
5. When finished cleaning the ashes reinstall the
window and burn pot.
6. CLEARING YOUR SECONDARY BURN PLATE IS A
MUST WHILE BURNING HARDWOOD PELLETS.
First, remove the ashtray and dispose of any ashes as
previously described, and reinstall ashtray. Second,
remove secondary burn plate. This will allow any built
up ashes and hot coals to fall into the ashtray. Inspect
the secondary burn plate, any layers of ash should be
removed and discarded. Lightly tap the secondary
burn plate on the edge of your disposal container
to clear any clogged hole(s) in the burn plate. This
will resume proper air flow through the burn plate;
reinstall the secondary burn plate.
Considering the numerous dierent fuels and
installations, there is no one formula for how often this
needs to be performed. Letting the secondary burn
plate build up with ashes can choke the stove causing a
decrease in temperature and increase the possibility of
smouldering fuel and smoke. Until experience has helped
you establish a regular routine it is not recommended
to leave the stove unattended for long periods of time.
ALWAYS EMPTY THE ASHTRAY AND CLEAR THE
SECONDARY BURN PLATE PRIOR TO LEAVING THE
STOVE UNATTENDED!
NEVER OPERATE THIS PRODUCT WHILE UNATTENDED

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 OF 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.
Ashes should be placed in a steel 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 cinders have been thoroughly cooled.
SMOKE AND 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. A working
smoke detector must be installed in the same room as
this product. Install a smoke detector on each floor of
your home; incase of accidental fire from any cause it
can provide time for escape. The smoke detector must be
installed at least 15 feet (4,57 M) from the appliance in
order to prevent undue triggering of the detector when
reloading.
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 AND GLASS GASKETS
Inspect the door and glass window gaskets periodically.
The door may need to be removed to have frayed, broken,
or compacted gaskets replaced by your authorized dealer.
This unit’s door uses a 0.125 x 1” flat gasket. Inspect and
clean the secondary burn plate, primary burn basket,
primary burn tube and ashtray prior to igniting the stove.
Do not operate your stove with the viewing door open,
safety concern may arise. The feed door must be closed
and sealed during operation.
PAINTED SURFACES
It is highly recommended that the initial burn of your new
stove be done outdoors. The paint used to coat your stove
a high temperature paint that is dry upon arrival but has
a final cure that happens during the initial burn. This
cure will last 20-30 minutes and will produce fumes and
some smoke.

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 glass is broken, follow
these removal procedures:
1. Remove the hinge pin located on the right side of the
window frame by pushing the pin-up and out.
2. The window frame will now swing open. Use caution
asglasswill now beloose. Performnecessarycleaning
and reinstall. NOTE: There are cleaning products
available at your local stove dealer specifically for
cleaning stove glass.
DO NOT USE SUBSTITUTE MATERIALS WHEN
REPLACING 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.
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. Scoop out the pellets. 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.

MAINTENANCE SCHEDULE
Establish a routine for the fuel, the burner, and the
firing technique. Check daily for creosote build-up until
experience shows how often cleaning is needed to be safe.
Be aware, hotter the fire the less creosote is deposited
so weekly cleaning may be necessary during colder
weather; however, monthly cleaning may be enough
during warmer months. NOTE: Failure to keep a clean
burn chamber or secondary burn plate can result in poor
stove performance. NOTE: Letting ash build up into the
primary burn basket can cause choking of the stove and
increase the risk of smoldering fuel and or smoke spillage.
