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 efficient 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 fire or fail to respect required clearances.

FLOOR PROTECTOR
This heater must have a non-combustible floor protector with an R-value of at least 1.4 installed beneath it if the floor is constructed of combustible material. If a floor pad is used, it should be UL listed or equal. The floor protector should be large enough to extend under the stove and beyond each side as indicated. If there is a horizontal run of flue pipe, there needs to be floor protection under it that extends two inches beyond either side of the pipe.

*Canadian Installations require 8” (204 mm)

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

• 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.

• The clearance between the flue pipe and a wall are valid only for vertical walls and for vertical flue pipe.

• If there is a horizontal run of flue pipe there must be at lease 18” of clearance between the pipe and the ceiling. There also has to be floor protection under the horizontal run that extends 2” beyond each side of the flue pipe.

• The chimney connector must not pass through an attic or roof space, closet or similar concealed space, a floor, 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 flue pipe crossing a combustible wall must have a minimum clearance of 18” (457.2mm).

• To reduce flue clearances from combustible materials, contact your local safety department.

OUTSIDE COMBUSTION AIR
Your wood stove is approved to be installed with an outside air intake (4FAK) which is necessary for a mobile home/transportable building. This type of installation is also required in air tight houses and houses with negative pressure problems. You can purchase this option through your heater dealer. Make sure to specify the part number mentioned in this booklet. Installation instructions are supplied with the air intake kit. Outside combustion air may be required if:

1. Your stove does not draw steadily, smoke roll-out occurs, wood burns poorly, or back-drafts occur whether or not there is combustion present.
2. Existing fuel-fired equipment in the house, such as fireplaces 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 fitting 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.

Slide the hose clamp over the aluminium flex pipe. Then slide the flex pipe over the air intake tube of the stove. Next tighten the hose clamp over the end of the aluminium flex hose.

FOR USE IN MOBILE HOME/TRANSPORTABLE BUILDINGS

• WARNING! DO NOT INSTALL IN SLEEPING ROOM.
• CAUTION! THE STRUCTURAL INTEGRITY OF THE MOBILE HOME/TRANSPORTABLE BUILDINGS FLOOR, WALL, AND CEILING/ROOF MUST BE MAINTAINED.
• INSTALL IN ACCORDANCE WITH 24 CFR, PART 3280 (HUD).
• USE A FACTORY BUILT CHIMNEY THAT COMPLIES WITH UL 103 STANDARDS; THEREFORE IT MUST BE A TYPE HT (2100°F).
• USE A SPARK ARRESTER.
• THE STOVE MUST BE ATTACHED TO THE STRUCTURE OF THE MOBILE HOME/TRANSPORTABLE BUILDINGS.

SECURING APPLIANCE’S ON A PEDESTAL

TO THE FLOOR
Use the designated holes to secure the unit 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 floor using the appropriate hardware needed for your specific flooring.
3. Install one bracket per leg or consult your local authority having jurisdiction to determine how many points of attachment are required.

In addition to the previously detailed installation requirements, the heater must be electrically grounded to the steel chassis of the mobile home/transportable building with 8 GA copper wire using a serrated or star washer to penetrate paint or protective coating to ensure grounding.

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 0.53 mm. 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 metal screws spaced an equal distance apart. 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. 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” (fireplace 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- puffing 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 CAN/ULC S629 standard; therefore it must be a Type HT (2100°F). It must be installed according to the manufacturer’s specifications. 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 specifications of the National Building Code. It must be lined with fire clay bricks, metal or clay tiles sealed together with fire cement. Round flues are the most efficient. The interior diameter of the chimney flue must be identical to the stove smoke exhaust. A flue which is too small may cause draft problems, while a large flue favors rapid cooling of the gas, and hence the build-up of creosote and the risk of chimney fires. 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 flue 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 definition, 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 fires.
4. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
5. Using a fire 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, firestops (where needed), insulation shield, roof flashing, 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.

COMBUSTIBLE WALL CHIMNEY CONNECTOR PASS-THROUGHS

METHOD A – 12” (305 mm) Clearance to Combustible Wall Member: Using a minimum thickness 3.5” (89 mm) brick and a 5/8” (16 mm) minimum wall thickness clay liner, construct a wall pass-through. The clay liner must conform to ASTM C315 (Standard Specification for Clay Fire Linings) or its equivalent. Keep a minimum of 12” (305 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 flue liner but not past the inner surface. Firmly grout or cement the clay liner in place to the chimney flue liner.

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 masonry chimney 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 gage (.024” [.61 mm]) 6” (153 mm) metal chimney connector, and a minimum 24 gage 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-gage 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” [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” (26mm) 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 flue line do not penetrate the inner 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 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.

WOOD STOVE UTILIZATION
Your heating appliance was designed to burn well seasoned natural wood only; no other materials should be burned. Any type of well seasoned natural wood may be used in your stove, but specific varieties have better energy yields than others. Higher efficiencies and lower emissions generally result when burning air dried seasoned hardwoods, as compared to softwoods or too green or freshly cut hardwoods. The following resources can assist in learning the burn characteristics of various species of wood:] http://firewoodresource.com /firewood-btu-ratings/; or https://forestry.usu.edu/forest-products/wood- heating
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. Waste and other flammable materials should not be burned in your stove.

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 fire starters made from paper, cardboard, sawdust, wax, and similar substances to start a fire 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 floor should be considered wet and requires full seasoning time. Standing deadwood can usually be considered to be about 2/3 seasoned. 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 logs. 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. 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 fire, even though the surface is dry, it may not be fully cured and should be seasoned longer.

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 overstressed; 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 fires
• low energy yield
• blackened windows
• incomplete log combustion

Do not burn manufactured logs made of wax impregnated sawdust or logs with any chemical additives.

TESTING YOUR WOOD

• When the stove is thoroughly warmed, place one piece of split wood (about five inches in diameter) parallel to the door on the bed of red embers.
• Keep the air control fully open and close the door. If the wood ignites 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 fire.

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
Efficiencies 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, efficiency calculated using the lower heating value of wood will be higher than efficiency calculated using the higher heating value. The best way to achieve optimum efficiencies 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 fire is established a lower burn rate may be a better option for efficient heating. A lower burn rate slows the flow 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 first two burns should be small fires and low temperatures (250°F) for a duration of 20 minutes each. The third fire 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 firings.
Notice: Use solid wood fuel only! Do not burn garbage, or flammable fluids. Do not use coal. This appliance is not designed to accommodate the air flow (draft) required to properly burn coal or coal products. Do not elevate the fire using grates or irons. Build the fire directly on the firebrick.

FUELING INSTRUCTIONS
This wood stove has been certified 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 efficiency and leads to accelerated creosote buildup in your chimney. Be considerate of the environment and only burn dry wood.

CAUTION
DO NOT LEAVE APPLIANCE UNATTENDED THE WITH DOOR OPEN.

For a cold start-up, place 4 to 5 pieces of newspaper into the firebox. On top of the newspaper, lay 4 lbs of kindling in random placement to ensure airflow through the kindling. On top of the kindling, place approximately 7 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.

Pull the air control out fully. 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 about a minute (or once your fire 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 29 lbs of fuel for the first high burn load.

After the first 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 34 lbs of cordwood and close the door immediately. Leave the air control fully open (in the “HI” position) for 5 minutes. After 5 minutes push in the air control to the medium position (midway between the “Low” and “Hi” position).

For a low burn setting once the high burn (or medium) fuel load is burned down to an established coal bed, load the unit with 32 lbs of cordwood and close the door immediately. Leave the air control fully open (in the “HI” position) for 4.5 minutes then close halfway. After 15 minutes begin to push the air control in to the “Low” postion (air control fully pushed in). NOTE: Do not close the air too quickly. Closing the air too quickly will cause the unit to smoke.

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.

VISIBLE SMOKE
The amount of visible smoke being produced can be an effective method of determining how efficiently 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 specific 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 efficiency. Any damage or deterioration of these tubes may reduce the efficiency 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 firebox 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 should be removed at the beginning of every “burn” season and air-blown clean, removing any dust or build-up.

CHIMNEY MAINTENANCE

NEVER OPERATE THIS PRODUCT WHILE UNATTENDED

CAUTION
DO NOT OVERFIRE APPLIANCE. YOU ARE OVERFIRING IF ANY PART OF THE APPLIANCE GLOWS RED. CLOSE THE DOOR AND SHUT DAMPER IMMEDIATELY TO REDUCE THE AIR SUPPLY AND SLOW DOWN THE FIRE.

CAUTION
SLOW BURNING FIRES FOR EXTENDED USE OR BURNING GREEN WOOD MAY CAUSE EXCESSIVE CREOSOTE BUILD-UP. IGNITION OF CREOSOTE OR OVERFIRING COULD CAUSE A CHIMNEY FIRE. CHIMNEY FIRES BURN EXTREMELY HOT AND MAY IGNITE SURROUNDING COMBUSTIBLE MATERIALS.

IN CASE OF A CHIMNEY FIRE, CALL THE FIRE 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 flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely high temper fire. 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 fire.

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 firebox is hot enough.
• Always check for creosote deposit once every two months and have your chimney cleaned at least once a year.
• If a chimney or creosote fire occurs, close all dampers immediately. Wait for the fire 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.

CAUTION
A CHIMNEY FIRE MAY CAUSE IGNITION OF WALL STUDS OR RAFTERS WHICH WERE ASSUMED TO BE A SAFE DISTANCE AWAY FROM THE CHIMNEY. IF A CHIMNEY FIRE OCCURS, HAVE YOUR CHIMNEY INSPECTED BY A QUALIFIED EXPERT BEFORE USING AGAIN.

ASH REMOVAL & DISPOSAL
Whenever ashes get 3 to 4 inches deep in your firebox or ash pan, and when the fire has burned down and cooled, remove excess ashes. Leave an ash bed approximately 1 inch deep on the firebox bottom to help maintain a hot charcoal bed. Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a non-combustible floor or the ground, away from all combustible materials, pending final disposal. The ashes should be retained in the closed container until all cinders have thoroughly cooled.

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.

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 confined 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

WARNING
NEVER OPERATE THE STOVE WITHOUT THE GASKET OR WITH A DAMAGED OR BROKEN GASKET. OPERATING WITHOUT A GASKET OR DAMAGED GASKET WILL RESULT IN DAMAGE TO YOUR STOVE AND CAN RESULT IN A HOUSE FIRE.

This unit’s door uses a 3/4” 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 efficiency 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.
