start or ‘freshen up’ a re in this stove. Keep all such
liquids well away from the stove while it is in use.
• Do not place clothing or other ammable items on
or near this stove.
• The fuel loading lid and stove top will be hot during
operation; therefore, you should always use the
provided tool or some type of hand protection
when refueling your stove.
• WARNING! DO NOT INSTALL IN SLEEPING ROOM.
• THE STRUCTURAL INTEGRITY OF THE MOBILE HOME
FLOOR, WALL, AND CEILING/ROOF MUST BE
MAINTAINED.
• A working smoke detector must be installed in the
same room as this product.
• Install vent at clearances specied by the vent
manufacturer.
• Do not connect the vent to a vent serving any other
appliance or stove.
• Do not install a ue damper in the exhaust venting
system of this unit.
• This wood heater needs periodic inspection and
repair for proper operation. It is against federal
regulations to operate this wood heater in a manner
inconsistent with operating instructions in this manual.
• Your stove requires periodic maintenance and
cleaning (see “MAINTENANCE”). Failure to maintain
your stove may lead to improper and/or unsafe
operation.
• Allow the stove to cool before performing any
maintenance or cleaning. Ashes must be disposed
in a steel container with a tight tting lid, and moved
outside immediately. The closed container of ashes
should be placed on a non-combustible surface
or on the ground, well away from all combustible

• Recognize the symptoms of CO poisoning
(headaches, nausea & drowsiness).
• Increase ventilation (open windows & doors).
• Make sure stove doors and/or lids are closed and
secured.
• Check stove for smoking or pufng (open airow
controls).
• Check chimney & connector pipe for leaks,
blockage or down-draft conditions.
• Check CO device for false alarm.
Safety Precautions

POSITIONING THE STOVE
It is very important to position the pellet stove as close as possible to the chimney, and in an area that will favor the
most efcient heat distribution possible throughout the house. The stove must therefore be installed in the room
where the most time is spent, and in the most spacious room possible. Recall that wood pellet stoves produce
radiating heat, the heat we feel when we are close to a wood pellet stove. A wood pellet stove also functions by
convection, that is through the displacement of hot air accelerated upwards and its replacement with cooler air.
The appliance must not be hooked up to a hot air distribution system since an excessive accumulation of heat
may occur.
This appliance must never be installed in a hallway or near a staircase, since it may block the way in case of re
or fail to respect required clearances.
MOBILE HOME INSTALLATIONS
Manufactured or Mobile home installations require that
the a solid fuel burning appliance be attached to the
oor of the mobile home. For this appliance there are two
ways of doing this.
Option 1: A mounting hole is provided in the rear of the
unit. Access the mounting hole through the rear of the unit
or by removing the side panel (see illustration). You can
then use the means necessary to attach the appliance
to the oor.
Option 2: Use the two brackets included with the unit to
secure the appliance to the oor. Slightly back the current
bolts out of the rear of the unit. Slide the bracket into
place and bolt the bottom ange to the oor. Retighten
the top bolt to the rear of the unit.
When installed in a mobile home the unit also has to be
connected to a source of fresh air from outside the home.
SAFETY NOTICE
• IF THIS STOVE IS NOT PROPERLY INSTALLED, A HOUSE FIRE MAY RESULT. TO REDUCE THE RISK OF FIRE, FOLLOW
THE INSTALLATION INSTRUCTIONS.
• CONSULT YOUR MUNICIPAL BUILDING DEPARTMENT OR FIRE OFFICIALS ABOUT PERMITS, RESTRICTIONS AND
INSTALLATIONS REQUIREMENTS IN YOUR AREA.
• USE SMOKE DETECTORS IN THE ROOM WHERE YOUR STOVE IS INSTALLED.
• KEEP FURNITURE AND DRAPES WELL AWAY FROM THE STOVE.
• NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR
LIQUIDS TO START OR “FRESHEN UP” A FIRE IN THIS HEATER. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE
HEATER WHILE IT IS IN USE.
• IN THE EVENT OF A CHIMNEY FIRE, PUSH THE AIR CONTROL FULL CLOSED TO DEPRIVE THE FIRE OF OXYGEN.
CALL THE FIRE DEPARTMENT.
• A SOURCE OF FRESH AIR INTO THE ROOM OR SPACE HEATED SHALL BE PROVIDED WHEN REQUIRED.
• For Manufactured or Mobile Homes, a room heater and it’s chimney shall not void the restopping required

CLEARANCES TO COMBUSTIBLES
It is of utmost importance that the clearances to combustible materials be strictly adhered to during installation
of the stove. Clearances may only be reduced by means approved by a regulatory authority. Contact your local
safety department or you may consult NFPA 211 if installing in the USA. Refer to the tables below in this section.
FLOOR PROTECTION (EMBER PROTECTION)
This heater must have a non-combustible oor protector (ember protection) installed beneath it if the oor is
of combustible material. If a oor pad is used, it should be UL listed or equal. The oor pad or non-combustible
surface should be large enough to extend a minimum of 16” [407mm] in front and 8” [204mm] on each side of the
heater. The area under a horizontal run of the chimney connector must also be protected; extending 2” (51mm)
beyond the outer dimension of the horizontal connector.
Canadian installations require a minimum of 18” [450mm] beyond the front of the unit and 8” [200mm] beyond
each side of the unit. A oor protector of 1/4” (7 mm) thick is recommended for this installation.
FLOOR PROTECTOR
The minimum sized oor protector for this stove is 41.8” X 35.4” (1062mm X 900mm) [Canada 43.8” X 35.4” (1113mm
X 900mm)]. Consult local building codes and re protection ordinances.

-6-
To
Appliance
• Floor to ceiling height must be at least 7’ (2.13m) in all cases.
• Do not place any combustible material within 4’ (1.2m) of the front of the unit.
• Never store your fuel within the specied clearances or within the space required for refueling and ash removal.
• The clearance between the ue pipe and a wall are valid only for vertical walls and for vertical ue pipe.
• The chimney connector must not pass through an attic or roof space, closet or similar concealed space, a
oor, or a ceiling.
• For Canadian installations, where passage through a wall, or partition of combustible construction is desired,
the installation must conform to CAN/CSA-B365, Installation Code for Solid-Fuel-Burning Appliances and
Equipment.
• A ue pipe crossing a combustible wall must have a minimum clearance of 18” (457.2mm).
• To reduce ue clearances from combustible materials, contact your local safety department or consult NFPA
211.
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 puf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.
CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same diameter as the stove outlet (6”). If this is not the
case, we recommend you contact your dealer in order to ensure there will be no problem with the draft. They
must also be a type suitable for burning solid fuel and must be in good condition and kept clean. The stove pipe
must be made of aluminized or cold roll steel with a minimum thickness of 0.021” or 0.53 mm. It is strictly forbidden
to use galvanized steel. Your smoke pipe should be assembled in such a way that the male section (crimped
end) of the pipe faces down. Attach each of the sections to one another with three equidistant metal screws.
Seal with furnace cement. The pipe must be short and straight. All sections installed horizontally must slope at
least 1/4 inch per foot, with the upper end of the section toward the chimney. Any installation with a horizontal
run of chimney pipe must conform to NFPA 211. You may contact NFPA (National Fire Protection Association) and
request the latest edition of the NFPA Standard 211. To ensure a good draft, the total length of the coupling pipe
should never exceed 8’ to 10’ (2.4m to 3.04m). (Except for cases of vertical installation, cathedral-roof style where
the smoke exhaust system can be much longer and connected without problem to the chimney at the ceiling of
the room). There should never be more than two 90 degrees elbows in the smoke exhaust system.

-7-
RECOMMENDATIONS FOR EXCESSIVE DRAFT
If experiencing excessive draft and/or fuel consumption with this unit, the use of a barometric draft regulator is
recommended. Chimney draft is critical to the proper operation and control of this stove. Too much draft will
cause fuel to be quickly consumed, create excessive heat, and potentially cause the stove to over re. Proper
draft for this stove will be measured with a draft gauge reading of between 0.04˝ to 0.05˝ w.c. The barometric
draft regulator is designed to be easily adjusted and provide proper operating draft levels. For installation and
operation instructions see the instructions included with the barometric draft regulator. If you are unable to install
a barometric draft regulator a limit plate can be installed on the damper of the stove.
LIMIT PLATE INSTALLATION
1. Insert the limit plate through the air slides slot.
2. Once inserted rotate counter clockwise and pull back rmly.
3. Once the limit plate is in position secure it into place using the supplied #10 screw. Once a qualied service
technician has installed the set limit do not alter it.
SAFETY NOTICE: IF THIS UNIT IS NOT PROPERLY INSTALLED, A HOUSE / BUILDING FIRE MAY RESULT. FOR YOUR
SAFETY, CONTACT LOCAL BUILDING OR FIRE OFFICIALS ABOUT PERMITS, RESTRICTIONS, AND INSTALLATION
REQUIREMENTS FOR YOUR AREA.

-8-
CHIMNEY
Your appliance may be hooked up with a 6” factory built or masonry chimney. If you are using a factory built
chimney, it must comply with UL 103 or CAN/ULC-S629 standard; therefore it must be a Type HT (2100°F). It is
extremely important that it be installed according to the manufacturer’s specications. If you are using a masonry
chimney, it is important that it be built in compliance with the specications of the National Building Code. It
must be lined with re clay bricks, metal or clay tiles sealed together with re cement. (Round ues are the most
efcient). The interior diameter of the chimney ue must not be smaller than the exhaust outlet of the appliance.
A ue which is too small may cause draft problems, while a large ue favours rapid cooling of the gas, and hence
the build-up of creosote and the risk of chimney res. Note that it is the chimney and not the stove which creates
the draft effect; your stove’s performance is directly dependent on an adequate draft from your chimney.
The following recommendations may be useful for the installation of your chimney:
1. Do not connect this unit to a chimney ue serving another appliance.
2. It must rise above the roof at least 3’ (0.9m) from the uppermost point of contact.
3. The chimney must exceed any part of the building or other obstruction within a 10’ (3.04m) distance by a
height of 2’ (0.6m).
4. Installation of an interior chimney is always preferable to an exterior chimney. Indeed, the interior chimney
will, by denition, be hotter than an exterior chimney, being heated up by the ambient air in the house.
Therefore the gas which circulates will cool more slowly, thus reducing the build-up of creosote and the risk
of chimney res.
5. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
6. Using a re screen at the extremity of the chimney requires regular inspection in order to ensure that it is not
obstructed thus blocking the draft, and it should be cleaned when used regularly.
7. All joints must be sealed inside and out.
8. The exterior section of the chimney should be double or triple wall.

-9-
FACTORY BUILT CHIMNEY
When a metal prefabricated chimney is used, the
manufacturer’s installation instructions must be followed.
You must also purchase (from the same manufacturer) and
install the ceiling support package or wall pass-through
and “T” section package, restops (where needed),
insulation shield, roof ashing, chimney cap, etc. Maintain
proper clearance to the structure as recommended by the
manufacturer. The chimney must be the required height
above the roof or other obstructions for safety and proper
draft operation. Never substitute alternative materials
for any of the manufacturer’s specied components
or complete the install without using all of the required
components.
MASONRY CHIMNEY
Ensure that a masonry chimney meets the minimum
standards of the National Fire Protection Association (NFPA)
by having it inspected by a professional. Make sure there are
no cracks, loose mortar or other signs of deterioration and
blockage. Have the chimney cleaned before the stove is
installed and operated. When connecting the stove through
a combustible wall to a masonry chimney, special methods
are needed.

-10-
Method A. 12” (304.8 mm) Clearance to Combustible Wall
Member: Using a minimum thickness 3.5” (89 mm) brick and a
5/8” (15.9 mm) minimum wall thickness clay liner, construct a
wall pass-through. The clay liner must conform to ASTM C315
(Standard Specication for Clay Fire Linings) or its equivalent.
Keep a minimum of 12” (304.8 mm) of brick masonry between
the clay liner and wall combustibles. The clay liner shall run
from the brick masonry outer surface to the inner surface of
the chimney ue liner but not past the inner surface. Firmly
grout or cement the clay liner in place to the chimney ue
liner.
Method B. 9” (228.6 mm) Clearance to Combustible Wall
Member: Using a 6” (152.4 mm) inside diameter, listed, factory-
built Solid-Pak chimney section with insulation of 1” (25.4 mm)
or more, build a wall pass-through with a minimum 9” (228.6
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” (228.6
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 ush with the inside of the masonry chimney
ue, and sealed with a non-water soluble refractory cement.
Use this cement to also seal to the brick masonry penetration.
Method C. 6” (152.4 mm) Clearance to Combustible Wall
Member: Starting with a minimum 24 gauge (.024” [.61 mm])
6” (152.4 mm) metal chimney connector, and a minimum 24
gauge ventilated wall thimble which has two air channels
of 1” (25.4 mm) each, construct a wall pass-through. There
shall be a minimum 6” (152.4) mm separation area containing
berglass 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” (152.4 mm) space. There should also be a
support sized to t 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 ue liner.
Method D. 2” (50.8 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” (25.4
mm) or more, and an inside diameter of 8” (2 inches [51 mm]
larger than the 6” [152.4 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” (25.4 mm) off 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 ue liner
do not penetrate ue liner.
NOTES:
• Connectors to a masonry chimney, 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 ue liner face.
• A chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a
oor, or ceiling.
COMBUSTIBLE WALL CHIMNEY CONNECTOR PASS-THROUGHS

-11-
OUTSIDE COMBUSTION AIR
It is recommended that this appliance be installed with an outside
air intake. This type of installation is also required for Canadian
installations, mobile homes and in air tight houses with negative
pressure problems. You can purchase this option through your
heater dealer or at your local hardware supply store. Installation
instructions should be supplied with the air intake kit.
Outside combustion air may be required if:
1. Your appliance does not draw steadily, smoke rollout occurs,
fuel burns poorly, or back-drafts occur whether or not there is
combustion present.
2. Existing fuel-red equipment in the house, such as replaces
or other heating appliances, smell, do not operate properly,
suffer smoke roll-out when opened, or back-drafts occur
whether or not there is combustion present.
3. Opening a window slightly on a calm (windless) day alleviates
any of the above symptoms.
4. The house is equipped with a well-sealed vapor barrier and
tight tting windows and/or has any powered devices that
exhaust house air.
5. There is excessive condensation on windows in the winter.
6. A ventilation system is installed in the house.
Outside Air Connection
4FAK Installation
If using outside combustion air, you can purchase a standard
4FAK from your dealer and install it on the rear of the appliance.
The inlet tubing used must be rigid and have a minimum material
thickness of 0.016 inches. Follow the manufacturer’s installation
instructions for attaching the 4FAK to the home.
HEATING
Controlled combustion is the most efcient technique for wood pellet heating because it enables you to select
the type of combustion you want for each given situation. The wood pellets will burn slowly if the heater air intake
control is adjusted to reduce the oxygen supply in the combustion chamber to a minimum. On the other hand,
wood pellets will burn quickly if the air control is adjusted to admit a larger quantity of oxygen in the combustion
chamber. The air intake control on your heater is very simple. If you raise the air control lever up as far as if will go, it
is fully open. If you push it down until if stops, the combustion air is reduced to the minimum setting. Real operating
conditions may give very different results than those obtained during testing according to the overall quality of
pellets used, the average size of the pellets, the length of the chimney, altitude and outside air temperature.

-12-
A. The unit is equipped with a temperature sensitive fuel
ap. This will stop the fuel ow if the unit gets too hot,
and will also close off the bottom of the hopper from
the re chamber when the unit is running out of fuel.
Note: The reset handle should always be in the down
position. If the handle remains in the up position it will
not work properly and damage may occur.
Before each fuelling, the control will have to be reset.
Lift up the handle on the right side panel of the unit,
to reset the control. You will hear a click when the
control is reset. Make sure the reset handle returns to
the down position. If the unit is running and needs to
be refuelled, it MUST be refuelled before the hopper
is empty. If you can see the fuel ap closed, you will
have to let the unit completely cool down before
refuelling.
B. The hopper on this unit must be sealed at all times during operation. This is achieved with a gasketed hopper
lid, and the lid is locked down with a compression latch. The latch has a button in the middle of it that when
pressed the latch will open. After refuelling the lid MUST be closed and latched for proper operation.
C. The lower access door has two main purposes. The rst purpose is for lighting the stove. The second purpose
is for accessing the ash pan.
D. The primary air control is located on the lower right hand side of the face of the unit. If the control is lifted all
the way up the unit damper is set to the maximum burn rate. If it is pushed all the way down it will reduce the
combustion air to the minimum burn rate.
E. The unit is equipped with a secondary burn basket in the combustion chamber. The basket can and will
need to be agitated as needed. The lever for agitating the basket is located on the lower left hand side of
the front of the unit.

THE FIRST FIRES
Follow the ignition steps in this manual. Make sure that there’s enough air circulation in the area of installation
while curing the appliance. The odors could be present during the rst 3 or 4 res. We suggest opening a window
during the curing process. People and animals with lung problems should take precautions during this time. Never
start your stove outside. You will not be able to see if you are over heating.
The rst few res in your new appliance need to be small so as to cure the fresh paint and preserve it’s quality.
To do so, rst follow the lighting instructions in the “Ignition” section of this manual. After ignition, the primary air
control needs to be left on the maximum setting for the rst 30 - 40 minutes. After 30 - 40 minutes, close down the
primary air control to a medium or medium low burn rate to maintain a small re in the unit, doing so will properly
cure the paint. Only ll the hopper with a minimum amount of fuel, approximate 10 lbs initially, then increase the
quantity up to full hopper capacity on subsequent burn cycles.
CAUTION: Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter uid, or similar liquids to
start or “freshen up” a re in this heater. Keep all such liquids well away from the heater while it is in use. Hot
while in operation. Keep children, clothing and furniture away. Contact may cause skin burns.

IGNITION
1. Open the hopper lid and check to make sure that the fuel ap is in
the open position. If it is not, use the handle on the right side of the
unit to reset. Fill the hopper with premium pellets (approximately 45
pounds), and close and latch the hopper lid to ensure it is sealed.
2. After lling the hopper with pellets, make sure that the air control is
set to the maximum setting.
3. Open the lower chamber door, and inspect the secondary burn basket for new unburned pellets. If there
are any unburned pellets that have fallen through the burn grate into the basket they must to be removed
before igniting the unit. Once the basket is cleaned out, swing the ignition port cover to the side and place
a ZIP re starter in the port.
4. Once the re starter is ignited and burning, close the combustion chamber door. If the re starter and pellets
are slow to ignite, it may be necessary to leave the combustion chamber door cracked for 5-10 minutes until
the unit is fully burning. NEVER leave the combustion chamber door open for longer than the rst 10 minutes,
this can cause unsafe burning conditions.
5. After the combustion chamber door is closed, allow the unit to burn on the maximum heat setting for 30-40
minutes before adjusting the damper and reducing the burn rate.
OPERATION
• DO NOT open viewing door during operation.
• DO NOT open the lower combustion chamber door during operation. After the ignition process the door must
remain closed and sealed while the unit is being operated. If the door is opened during operation it can cause
unsafe burning conditions.
• DO NOT refuel the unit if the fuel level is down to where you can see the fuel ap.
During operation if the fuel level in the hopper gets down to the fuel cut off ap, you can not refuel the unit until
it is completely cool. As the unit burns, coals will build up in the secondary burn basket, the basket will need to
be agitated periodically to level out the coals. A good example of this is if the coals are building up close to the
burn grate the basket needs to be agitated. NOTE: This appliance does not have a “quick” shutdown method.
Once the appliance has been charged with fuel, ignited and burning, it will burn until all fuel has been consumed
by combustion. Please note that once the re does cease, the appliance may still be quite warm or HOT and
could remain Hot for an undetermined amount of time depending on ring conditions. Experience burning your
appliance, will tell you how many pellets to put in the hopper in order to burn for a desired period of time. This
unit may run anywhere from 1 - 6 hours on a single 10 lb charge depending on the air adjustment setting and
quality of fuel used. You may use the below primary air settings as a good starting point when burning your new
appliance. Please note that these settings may vary depending on certain factors that may affect combustion.
CAUTION:
• Do not ever attempt to light the stove from the bottom of the
primary burn grate. Always use the ignition port to start the unit.
• Do not ever attempt to light the stove with the upper chamber
access door open.
• Do not ever attempt to light the stove with coals remaining in the
re pot drop tube or on the primary burn grate.
• Do not ever attempt to light the stove without rst resetting the
temperature sensitive fuel ap. Ensure the fuel ap is in the open
position.
• Allow the unit to cool to the touch before refueling and lighting, of
the unit runs out of fuel, or if the fuel level is below the fuel cut off
ap.

WARNINGS
• NEVER OVERFIRE YOUR STOVE. IF ANY PART OF THE STOVE STARTS TO GLOW RED, OVER FIRING IS HAPPENING.
READJUST THE AIR INTAKE CONTROL AT A LOWER SETTING.
• ATTEMPTS TO ACHIEVE HEAT OUTPUT RATES THAT EXCEED HEATER DESIGN SPECIFICATIONS CAN RESULT IN
PERMANENT DAMAGE TO THE HEATER.
VISIBLE SMOKE
The amount of visible smoke being produced can be an effective method of determining how efciently the
combustion process is taking place at the given settings. Visible smoke consist of unburned fuel and moisture
leaving your stove. Learn to adjust the air settings of your specic unit to produce the smallest amount of visible
smoke.
RELOADING
If you wish to continue burning your heater after the majority of the fuel has been consumed, make sure to add
more fuel before the fuel cut off ap is visible. The fuel cut off functions with heat, as the pellets get lower in the
re pot the ap will close and not be able to be reset until the unit is completely cool.
It is important to note that wood combustion consumes ambient oxygen in the room. In the case of negative
pressure, it is a good idea to allow fresh air in the room, either by opening a window slightly or by installing a fresh
air intake system on an outside wall.
CREOSOTE - FORMATION AND NEED FOR REMOVAL
When 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 of a slow-burning re. As a
result, creosote residue accumulates on the ue lining. When ignited this creosote makes an extremely hot re.
The chimney connector and chimney should be inspected at least once every two months during the heating
season to determine if a creosote build-up has occurred. If creosote has accumulated (3mm or more), it should
be removed to reduce the risk of a chimney re.
TO PREVENT CREOSOTE BUILD UP
• Always burn PFI certied premium grade pellets. This allows clean burns and higher chimney temperatures,
therefore less creosote deposit.
• Leave the air control full open for about 5 min. every time you refuel the appliance to bring it back to proper
operating temperatures. The secondary combustion can only take place if the rebox is hot enough.
• Always check for creosote deposit in your chimney once every two months and have your chimney cleaned
at least once a year.
If a chimney or creosote re occurs, close all dampers immediately. Wait for the re to go out and the heater to
cool, then inspect the chimney for damage. If no damage results, perform a chimney cleaning to ensure there is
no more creosote deposits remaining in the chimney.
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.
TOOL HOOK
Use the screw located on the front middle right hand side of the of the unit to attach the handle hook to the unit.

-15-
Your wood pellet stove is a high efciency stove however, still requires that maintenance be performed on a
regular basis. Maintenance is a vital key in maintaining your stove’s efciency, operation, and longevity. It is
important to perform a visual inspection of the appliance every time it is emptied and cleaned, in order to ensure
that no parts have been damaged, in which case repairs must be performed immediately. Inspect and clean
the chimney and connector pipe periodically for creosote buildup or obstructions. Inspection should be done at
least monthly during the heater season.
SECONDARY AIR PORTS
Cleaning the Secondary Air Ports regularly will help keep your heater
burning clean and efciently. Remove any ash or creosote build-up
from the ports as frequently as needed. A simple brush with a small
chimney sweep broom once a week will help reduce or prevent
any large deposits from bonding to this surface which could cause
premature deterioration of the rebox. Most Creosote formations
here can be removed.
ASH DISPOSAL / ASH PAN AREA
Ashes should be removed daily or if they are within approximately an inch of the bottom of the secondary burn
grate. The secondary burn grate should be agitated when ashes build up within approximately two inches of
the primary burn grate. Always empty the stove when it is cold, such as in the morning. Never open the lower
combustion chamber door to empty the ash pan while the unit is in operation, this could cause an overre
situation. Remove any accumulated ash or fallen pellets from the ash pan area. An ash vac greatly aids in this
process and can be purchased from your local dealer. Ashes should be placed in a steel container with a tight
tting lid and moved outside immediately. The closed container of ashes should be placed on a non combustible
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 cinders
have thoroughly cooled. Other waste shall not be placed in this container.
CAUTIONS
• ASHES COULD CONTAIN HOT EMBERS EVEN AFTER TWO DAYS WITHOUT OPERATING THE STOVE.
• KEEP ASH PAN AREA CLEAN.
• THE ASH PAN CAN BECOME VERY HOT. WEAR GLOVES TO PREVENT INJURY.
• NEVER BURN THE STOVE WITH THE ASH TRAP OPEN. THIS WOULD RESULT IN OVER FIRING THE STOVE, DAMAGE
TO THE STOVE AND EVEN HOUSE FIRE MAY RESULT.
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 conned
areas can be dangerous. Make sure your 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.
GLASS
• Inspect and clean the glass regularly in order to detect any cracks. If you spot one, schedule to replace
immediately. Do not abuse the glass door by striking or slamming shut. Do not use the stove if the glass is
broken.
• If the glass on your stove breaks, replace only with the glass supplied from your heater dealer. Never substitute
other materials for the glass.
• To replace the glass, remove the nuts retaining the glass clips inside the door. Remove the clips and replace
the damaged piece with a new one. Perform the procedure backwards after replacing. When replacing the
glass, you should change the glass gasket to make sure you keep it sealed.
• Never wash the glass with abrasive cleaners or with a product that may scratch. Use a specialized product,
available in the stores where pellet stoves are sold. The glass should be washed only when cold, NEVER CLEAN
WHEN HOT.
Air Ports
Maintenance
CAUTION: Do not perform maintenance or cleaning on the unit until it has cooled to room temperature completely

-16-
GASKETING
This unit’s doors use a 1/2” diameter rope gasket. It is recommended that you check your gaskets twice a month
during the heating season and change the gaskets (which makes your stove air tight) once a year, in order to
ensure good control over the combustion, maximum efciency and security. To check for a proper seal, you
should do a paper slip test. Do so by taking a thin piece of paper about the size and thickness of a dollar bill.
Place the paper between the gasket and the sealing surface, then close and latch the door/lid. You should
feel a resistance when tugging on the paper slip, which may vary, but should always have resistance. Perform
this test on every side of the seal, top, bottom, left and right, if possible. If the paper slip pulls out with little or no
resistance, you need to adjust the lid/door and/or replace the gasket. To change the gaskets, simply remove the
damaged one, carefully clean the available gasket groove, apply a gasket cement sold for this purpose, and
install the new gasket. When installing the gasket, never stretch the gasket. You may light up your stove again
approximately 24 hours after having completed this operation.
PAINT
Only clean your stove with a dry soft cloth that will not harm the paint nish. If the paint becomes scratched or
damaged, it is possible to give your wood pellet stove a brand new look, by repainting it with a 1200° F heat
resistant paint that can be purchased from your dealer. For this purpose, simply scrub the surface to be repainted
with ne sand paper, clean it properly, and apply thin coats (2) of paint successively. Remember, if paint is
applied to the stove in large amounts or over large spots, you need to follow the First Fires procedure described
previously in this manual.
OFF SEASON MAINTENANCE
It is a good idea to give your stove a thorough cleaning at the end of each heating season to decrease the
chances of rust occurring during the off-season. Do this, especially, on the inside of your rebox. Wipe the outside
of the appliance with a non-abrasive cleaner (Windex) and a rag, allow it to dry, then touch-up any spots with
high temperature paint sold by your local dealer. Spraying the inside of the rebox with a rust inhibitor instead of
paint, can also help.
WARNING: Never operate the appliance without a gasket or with a broken one. Damage to the appliance or
even house re may result.
