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
under the stove and beyond each side as indicated. If there is
a horizontal run of ue pipe, there needs to be oor protection
under it that extends two inches beyond either side of the pipe.
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.
• DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.
• A SOURCE OF FRESH AIR INTO THE ROOM OR SPACE HEATED SHALL BE PROVIDED WHEN REQUIRED.
POSITIONING THE STOVE
It is very important to position the wood 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 stoves produce
radiating heat, the heat we feel when we are close to a wood stove. A wood stove also functions by convection,
that is through the displacement of hot air accelerated upwards and its replacement with cooler air. If necessary,
the hot air distribution from the stove may be facilitated by the installation of a blower. The wood stove must not
be hooked up to a hot air distribution system since an excessive accumulation of heat may occur. A wood stove
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.
Installation

-5-
• Do not place any combustible material within 4’
(1.2m) of the front of the unit.
• 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.
• 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.
SPECIAL MOBILE HOME REQUIREMENTS
WARNING! - Do not install in a sleeping room.
CAUTION! - The structural integrity of the mobile home oor, wall, and ceiling/roof must be maintained.
In addition to the previously detailed installation requirements, mobile home installations must meet the following
requirements:
• The space heater is to be connected to a factory-built chimney conforming to CAN/ULC-S629, Standard for
650°C Factory-Built Chimneys.
• The heater must be permanently attached to the oor. There are two holes in the pedestal base, use 3/8” bolts
through the oor.
• The heater must be electrically grounded to the steel chassis of the mobile home with 8 GA copper wire using
a serrated or star washer to penetrate paint or protective coating to ensure grounding.
• When moving your mobile home, all exterior venting must be removed while the mobile home is being
relocated. After relocation, all venting must be reinstalled and securely fastened.
• Outside Air is mandatory for mobile home installation. See your dealer for purchasing.
• Check with your local building ofcials as other codes may apply.
• Only use the specied components listed in this manual for this unit. The use of components that are not meant
for this unit can cause unsafe conditions.
COMBUSTION AIR ASSEMBLY INSTRUCTIONS (MOBILE HOME INSTALLATIONS - REQUIRED)

CLEARANCES TO COMBUSTIBLES
It is of utmost importance that the clearances to combustible materials be strictly adhered to during installation
of the stove. Refer to the provided tables:

-6-
• 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-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.
• 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 tting 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.
If an outside air intake is required, you may purchase a standard 4” Dryer Vent kit from your local hardware supply
store and install it on the rear of the appliance.
When using a Dryer venting kit, the outlet cover must be of a design that DOES NOT close by means of a ap or
trap door. You must purchase a style that allows a continuous in-ow of air and that has a rodent screen. This
adapter can be purchased from your dealer.
4FAK INSTALLATION
Follow the manufacturer’s installation instructions for attaching the dryer vent kit to the home. Then, attach it to
the adapter on the combustion air inlet on the back of the pedestal as shown.
SECURING APPLIANCE’S WITH LEGS TO THE FLOOR
1. The bracket engages around the square extrusion
of the leveling bolt inserted into the leg.
2. Once appliance is leveled, position the bracket
and attach to the oor using the appropriate
hardware needed for your specic ooring.
3. Install one bracket per leg or consult your local
authority having jurisdiction to determine how
many points of attachment are required.
SECURING APPLIANCE’S ON A PEDESTAL TO THE FLOOR
Use the designated holes to secure the unit to the oor.
“Dryer Venting Kit”
Installation
Slide the hose clamp over the aluminium ex pipe. Then slide the
ex pipe over the air intake tube of the stove. Next tighten the hose
clamp over the end of the aluminium ex hose.

-7-
CHIMNEY CONNECTOR (STOVE PIPE)
The 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 to ensure there will be no problem with the
draft. The stovepipe must be made of aluminized or cold roll steel
and have a minimum thickness of 0.021” or 0.53mm. It is strictly
forbidden to use galvanized steel. The smoke pipe should be
assembled to promote the male section (crimped end) of the
pipe to be faced down. Attach each section to another with three
equidistant metal screws. 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. 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, in a 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. The installation of a “barometric draft stabilizer”
(replace register) on a smoke exhaust system is prohibited. Furthermore, the installation of a draft damper is not
recommended. With a controlled combustion wood stove, the draft is regulated upon intake of the combustion
air in the stove and not at the exhaust.
IMPORTANCE OF PROPER DRAFT
Draft is a force that 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. An inadequate draft may cause back-pufng into the
room and “plugging” of the chimney. An 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 an
excessive draft.
CHIMNEY
Your wood stove 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 CSA-B365
standard; therefore it must be a Type HT (2100°F). It
must be installed according to the manufacturer’s
specications. 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. If you are using a masonry chimney, it
must 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 be identical to the
stove smoke exhaust. A ue which is too small may cause draft problems, while a large ue favors 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. Do not connect this unit to a chimney ue serving another appliance.
The following recommendations may be useful for the installation of your chimney:
1. It must rise above the roof at least 3’ (0.9m) from the uppermost point of contact.
2. 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).
3. The 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.
4. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
5. Using a re screen at the extremity of the chimney requires regular inspection to ensure that it is not obstructed
thus blocking the draft, and it should be cleaned when used regularly.

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.
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. Be sure to 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.

-9-
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 gage (.024” [.61 mm])
6” (152.4 mm) metal chimney connector, and a minimum
24 gage 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-gage 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 gage 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 line do not penetrate the inner liner.
NOTES:
1. 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.
2. A chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a
oor, or ceiling.

WOODSTOVE UTILIZATION
Your heating appliance was designed to burn wood only; no other materials should be burned. Waste and
other ammable materials should not be burned in your stove. Any type of wood may be used in your stove, but
specic varieties have better energy yields than others. Please consult the following table in order to make the
best possible choice.
It is EXTREMELY IMPORTANT that you use DRY WOOD only in your wood stove. The wood should have dried for
9 to 15 months, such that the humidity content (in weight) is reduced below 20% of the weight of the log. It is
very important to keep in mind that even if the wood has been cut for one, two, or even more years, it is not
necessarily dry, if it has been stored in poor conditions. Under extreme conditions it may rot instead of drying.
This point cannot be over stressed; the vast majority of the problems related to the operation of a wood stove is
caused by the fact that the wood used was too damp or had dried in poor conditions. These problems can be:
- ignition problems
- creosote build-up causing chimney res
- low energy yield
- blackened windows
- incomplete log combustion
Smaller pieces of wood will dry faster. All logs exceeding 6” in diameter should be split. The wood should not be
stored directly on the ground. Air should circulate through the cord. A 24” to 48” air space should be left between
each row of logs, which should be placed in the sunniest location possible. The upper layer of wood should be
protected from the element but not the sides.
TESTING YOUR WOOD
• When the stove is thoroughly warmed, place one piece of split wood (about ve inches in diameter) parallel
to the door on the bed of red embers.
• Keep the air control full open and close the door. If ignition of the piece is accomplished within 90 seconds
from the time it was placed in the stove, your wood is correctly dried. If ignition takes longer, your wood is
damp.
• If your wood hisses and water or vapor escapes at the ends of the piece, your wood is soaked or freshly cut
(green). Do not use this wood in your stove. Large amounts of creosote could be deposited in your chimney,
creating potential conditions for a chimney re.
Fuel Recommendations

-11-
WOOD STOVE UTILIZATION
The operation of this wood heater in a manner inconsistent with the owner’s manual will void your warranty and is
also against federal regulations. This heater is designed to burn natural wood only. Higher efciencies and lower
emissions generally result when burning air dried seasoned hardwoods, as compared to softwoods or too green
or freshly cut hardwoods.
DO NOT BURN:
1. Garbage;
2. Lawn clippings or yard waste;
3. Materials containing rubber, including tires;
4. Materials containing plastic;
5. Waste petroleum products, paints or paint thinners,
or asphalt products;
6. Materials containing asbestos;
7. Construction or demolition debris;
8. Railroad ties or pressure-treated wood;
9. Manure or animal remains;
10. Saltwater driftwood or other previously salt water-
saturated materials;
11. Unseasoned wood; or
12. Paper products, cardboard, plywood, or
particleboard. The prohibition against burning
these materials does not prohibit the use of re
starters made from paper, cardboard, sawdust,
wax, and similar substances to start a re in an
affected wood heater.
Burning these materials may result in the release of toxic fumes or render the heater ineffective and cause smoke.
Deadwood lying on the forest oor should be considered wet and requires full seasoning time. Standing deadwood
can usually be considered to be about 2/3 seasoned. Splitting and stacking wood before it is stored accelerates
the drying time. Storing wood on an elevated surface from the ground and under a cover or covered area from
rain or snow also accelerates the drying time. A good indicator of if the wood is ready to burn is to check the
piece ends. If cracks are radiating in all directions from the center then the wood should be dry enough to burn.
If your wood sizzles in the re, even though the surface is dry, it may not be fully cured and should be seasoned
longer.
Do not burn manufactured logs made of wax impregnated sawdust or logs with any
chemical additives. Manufactured logs made of 100% compressed sawdust can be
burned, but be careful burning too much of these logs at the same time. Start with one
manufactured log and see how the stove reacts. You can increase the number of logs
burned at a time but make sure the temperature never rises higher than 475 °F (246 °C) on
a magnetic thermometer for installation on single wall stove pipes or 900 °F (482 °C) on a
probe thermometer for installation on double wall stove pipe. The thermometer should be
placed about 18” (457 mm) above the stove. Higher temperatures can lead to overheat
and damage your stove.
Operating Instructions
CAUTIONS: HOUSE FIRE HAZARDS
• Do not store wood on oor protector, underneath stovepipe(s) if applicable, or anywhere within clearances
to combustible surfaces specied for this appliance.
• Never operate with secondary tubes, ber board, or insulation removed.
OPERATING SAFETY PRECAUTIONS
• Never overre this appliance by building excessively hot res as a house/building re may result. You are
overring the appliance if it begins to glow or turn red.
• Never build excessively large res in this type of appliance as damage to the rebox or smoke leakage may
result.
• Do not build re too close to glass.
• Hot while in operation. Keep children, clothing, and furniture away. Contact may cause skins burns. Do not
touch the appliance until it has cooled.
• Provide adequate air for combustion to the room where the appliance is installed.
• Inspect chimney liner every 60 days. Replace liner immediately if it is rusting or leaking smoke into the room.
• Attempts to achieve heat output rates that exceed heater design specications can result in permanent
damage to the heater.
WARNING: EXPLOSION HAZARD
• Never use chemicals, gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter uid, or similar
ammable liquids to start or “freshen up” a re in the appliance.
• Keep all ammable liquids, especially gasoline, out of the vicinity of the appliance - whether in use or in
storage.

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.
EFFICIENCIES
Efciencies can be based on either the lower heating value (LHV) or the higher heating value (HHV) of the fuel.
The lower heating value is when water leaves the combustion process as a vapor, in the case of woodstoves the
moisture in the wood being burned leaves the stove as a vapor. The higher heating value is when water leaves
the combustion process completely condensed. In the case of woodstoves this would assume the exhaust gases
are room temperature when leaving the system, and therefore calculations using this heating value consider
the heat going up the chimney as lost energy. Therefore, efciency calculated using the lower heating value of
wood will be higher than efciency calculated using the higher heating value. The best way to achieve optimum
efciencies is to learn the burn characteristic of you appliance and burn well-seasoned wood. Higher burn rates
are not always the best heating burn rates; after a good re is established a lower burn rate may be a better
option for efcient heating. A lower burn rate slows the ow of usable heat out of the home through the chimney,
and it also consumes less wood.
NOTICE - INITIAL BURNS TO CURE PAINT
BECAUSE OF THE HIGH OPERATING TEMPERATURES, THIS APPLIANCE IS COATED WITH A SPECIAL HIGH TEMP PAINT
WHICH REQUIRES A SERIES OF LOW TO MEDIUM BURNS TO FULLY CURE FOR DURABILITY AND A LIFETIME OF SERVICE.
Proper curing of the high-temp paint requires a series of three initial burns. The appliance should be allowed to
cool off between each burn. The rst two burns should be small res and low temperatures (250°F) for a duration
of 20 minutes each. The third re should be at a temperature of approximately 500°F for 20 minutes. Provide
adequate cross ventilation to clear any smoke or odor caused by initial rings.
FUELING INSTRUCTIONS
This wood stove has been certied by the US EPA to meet strict 2020 guidelines. To ensure this unit produces
the optimal minimum emissions it is critical that only well-seasoned cordwood is burned (see the “Fuel
Recommendations” section of this manual). Burning unseasoned wet wood only hurts your stoves efciency and
leads to accelerated creosote buildup in your chimney. Be considerate of the environment and only burn dry
wood.
For a cold start-up, place 4 to 5 pieces of newspaper into the rebox. On top of the
newspaper, lay 2.5 lbs of kindling in random placement to ensure airow through
the kindling. On top of the kindling, place approximately 3.5 to 4 lbs of small pieces
of cordwood. NOTE: Use smaller pieces of wood during start-up and a high burn
rate to increase the stove temperature.
CAUTION: DO NOT LEAVE APPLIANCE UNATTENDED THE WITH DOOR OPEN.
3.5 to 4 lb
Notice: Use solid wood fuel only! Do not burn garbage , or ammable uids. Do not use coal. This appliance
is not designed to accommodate the air ow (draft) required to properly burn coal or coal products. Do not
elevate the re using grates or irons. Build the re directly on the rebrick.

-13-
After the rst high burn load and the stove is well warmed up, adjust the unit as needed for a medium or low burn
setting.
For a medium burn, once the high burn fuel load is burned down to an established coal bed, load the unit with
16 lbs of cordwood and close the door immediately. Leave the air control fully open (in the “HI” position) for 5
minutes. After 5 minutes the air control can be put in the medium setting which is about 1” open from the fully
closed position.
For a low re burn setting, follow the same procedure as a medium burn for loading and initial ignition. After 5
minutes of burning, slowing move your air to the fully closed position. NOTE: The closing down procedure should
take 15 minutes. Do not close the air too quickly. Closing the air too quickly will cause the unit to smoke.
14 lbs
HIGH
16 lbs
LOW
Pull the air control out fully (in the “HI” position).
Light the newspaper and leave the door slightly
open for about a minute. NOTE: You may have
to leave it open a bit longer, depending on your
chimney height and outdoor conditions. After
one minute (or once the re is well started) close
the door and allow the kindling to ignite. Once
the kindling has burned down to a starter coal
bed, load the unit with approximately 14 lbs of
fuel for the rst high burn load.
ADDING FUEL
1. Once you have obtained a good bed of embers, you should reload the unit. To do so, open the air controls
to maximum a few seconds before opening the stove’s door.
2. Open the door very slowly; open it one or two inches for 5 to 10 seconds, before opening it completely to
increase the draft and thus eliminate the smoke which is stagnant in a state of slow combustion in the stove.
3. Rake the glowing embers to the front of the stove. Add fuel being careful not to overload or overre the
appliance. When adding fuel be careful not to smother the re. Do not build res against glass and make sure
the embers do not obstruct the air inlet. Do not allow logs to roll and strike the glass.
NOTE: For optimal operation of this unit, it is recommend to operate it with a wood load approximately equivalent
to the height of re bricks. 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.
4. Close the feed door and secure tightly.
5. Adjust the air inlet control as described in the “Fueling Instruction” section of this manual.
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.
• THE INSTALLATION OF A LOG CRADLE OR GRATES IS NOT RECOMMENDED IN YOUR WOOD STOVE. BUILD FIRE
DIRECTLY ON FIREBRICK.
• NEVER PUT WOOD ABOVE THE FIREBRICK LINING OF THE FIREBOX.
• ATTEMPTS TO ACHIEVE HEAT OUTPUT RATES THAT EXCEED HEATER DESIGN SPECIFICATIONS CAN RESULT IN
PERMANENT DAMAGE TO THE HEATER.

-14-
CAUTION:
Do not overre appliance. You are overring if any part of the appliance glows red. Close the door and shut
damper immediately to reduce the air supply and slow down the re.
Chimney Maintenance
CAUTION:
Slow burning res for extended use or burning green wood may cause excessive creosote build-up. Ignition of
creosote or overring could cause a chimney re. Chimney res burn extremely hot and may ignite surrounding
combustible materials. In case of a chimney re, call the re department immediately!
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 high temper 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 (3 mm or more), it should
be removed to reduce the risk of a chimney re.
We strongly recommend that you install a magnetic thermometer on your smoke exhaust pipe, approximately
18” above the stove. This thermometer will indicate the temperature of your gas exhaust fumes within the smoke
exhaust system. The ideal temperature for these gases is somewhere between 275°F and 500°F. Below these
temperatures, the build-up of creosote is promoted. Above 500°F, heat is wasted since a too large quantity is lost
into the atmosphere.
TO PREVENT CREOSOTE BUILD UP
• Always burn dry wood. This allows clean burns and higher chimney temperatures, therefore less creosote
deposit.
• Leave the air control fully open for about 5 min. every time you reload the stove 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 once every two months and have your chimney cleaned at least once a
year.
6. Empty ashes regularly. Do not allow ashes to pile up. Properly dispose of hot ashes (see the “Ash Removal And
Disposal” section of this manual).
7. Burn small, intense res instead of large, slow burning res when possible. Large slow burning res can deposit
creosote within the heating system.
8. Learn your appliance’s operating characteristics to obtain optimum performance.
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 in the given settings. Visible smoke consists 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. Wood that has not been seasoned properly and has a high wood moisture content will produce excess
visible smoke and burn poorly.
AIR TUBES
The air tubes assembled in this unit are designed to provide an accurate mix of secondary air to ensure the
highest efciency. Any damage or deterioration of these tubes may reduce the efciency of combustion. The air
tubes are held in position by screws or snap pins. Locate these to either side of the tube and remove it to allow
the tube to be removed and replaced.
BLOWER OPERATION
The variable speed blower circulates air warmed by the rebox into the living area to distribute the heat more
evenly. The blower control knob is located on the side of the blower housing. Turn the knob clockwise to turn the
blower on. The speed is controlled by turning the knob clockwise for slower speeds and counter-clockwise for
faster speeds. To turn the blower off, turn the speed control knob fully counter-clockwise. It is recommended to
turn the blower off when the unit is not in operation. The blower needs to be removed and air-blown clean. Make
sure the blades do not have build up.

-15-
ASH REMOVAL & DISPOSAL
Whenever ashes get 3 to 4 inches deep in your rebox or ash pan, and when the re has burned down and cooled,
remove excess ashes. Leave an ash bed approximately 1 inch deep on the rebox bottom to help maintain a hot
charcoal bed. Ashes should be placed in a metal container with a tight-tting lid. The closed container of ashes
should be placed on a non-combustible oor or the ground, away from all combustible materials, pending nal
disposal. The ashes should be retained in the closed container until all cinders have thoroughly cooled.
CAUTION:
A chimney re may cause ignition of wall studs or rafters which were assumed to be a safe distance away from
the chimney. If a chimney re occurs, have your chimney inspected by a qualied expert before using again.
ATTENTION:
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.
WARNING:
NEVER OPERATE THE STOVE WITHOUT A GASKET OR WITH A BROKEN ONE. DAMAGE TO THE STOVE OR EVEN
HOUSE FIRE MAY RESULT.
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. 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 CARE
• Inspect and clean the glass regularly to detect any cracks. If you spot one, turn the stove off 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 screws retaining the glass moldings inside the door. Remove the moldings
and replace the damaged piece with a new one. Perform the procedure backward after replacing it. When
replacing the glass, you should change the glass gasket to make sure you keep it sealed.
• Never wash the glass with a product that may scratch. Use a specialized product, available in the stores where
wood stoves are sold. The glass should be washed only when cold.
GASKET CARE
This unit’s door uses a 1” diameter rope gasket. It is recommended that you change the door gasket (which makes
your stove door air tight) once a year, in order to ensure good control over the combustion, maximum efciency
and security. To change the door gasket, simply remove the damaged one. Carefully clean the available gasket
groove, apply a high temperature silicone sold for this purpose, and install the new gasket. You may light up your
stove again approximately 24 hours after having completed this operation.
CAUTIONS:
• ASHES COULD CONTAIN HOT EMBERS EVEN AFTER TWO DAYS WITHOUT OPERATING THE STOVE.
• 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.
• 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
no more creosote deposits is remaining in the chimney.
