WARRANTY REGISTRATION
Please register your SUPREME product online at http://www.suprememcom’reqistration.php to ensure full warranty coverage. Proof of purchase is required for all warranty claims.

Combustion Air Control
The Combustion Air Control is a patented mechanism (Patent No: US 7,325,541 B2) that regulates the air flow into the firebox based on the temperature of the unit. It is located on the top of the firebox, at the front center of the unit (see Figure 2-1). The combustion air control of the FUSION has two components: the Activator and the Burn Rate Selector. The left combustion control lever is the Activator. When starting a fire or adding a new load of wood, the Activator must be pushed in to allow a primary source of air to enter the firebox. The Activator will retract automatically with heat. The right combustion control lever is the Burn Rate Selector. The Burn Rate Selector can slide sideways to achieve different burn rates. When the Burn Rate Selector is positioned to the left, a maximum burn rate is achieved and when it is positioned to the right, a minimum burn rate is set.
WARNING: Never manipulate the Combustion Air Control with bare hands as it gets hot when the FUSION is in operation. Use the Cold Hand Key (see Section 2.6) to adjust the Combustion Air Control.

Baffle Secondary Burn Technology
The baffle system (18FN1150 or 24FN1150) of the FUSION insert is located within the upper portion of the firebox (Figure 2-2) and is fastened by 6 bolts (3/8 Hex). SUPREME baffle systems are constructed out a specific grade of stainless steel capable of withstanding high-temperature conditions. The secondary combustion air is drawn into the baffle system, pre-heated, and distributed below the lower plate, allowing for a cluster of small flames flowing downwards. This effect is more visible in the minimum burn rates. For optimal performance, it is recommended to clean any creosote build-up on the lower plate of the baffle system.

Cold Hand Key
The Cold Hand Key (Figure 2-3) is an accessory that comes standard with the FUSION insert. The Cold Hand Key is a tool used to manipulate the Combustion Air Control Levers when it is hot.

Chimney Sweeping Cap
The chimney sweeping cap (Figure 2-4) found at the baffle of the FUSION allows easy access for chimney sweeping without having to remove any components of the firebox.
WARNING: The chimney sweeping cap should be blocking the access to the chimney at all times during combustion. A chimney sweeping cap that is not blocking the baffle hole during combustion is a safety hazard, will overheat the fireplace and void the warranty.

Door
The FUSION wood burning insert comes with a Pyroceramic glass panel door. Pyroceramic is the highest grade available for fireplaces and stoves and can withstand temperatures up to 1300oF. To remove the door, open the door, lift it and pull it towards the bottom until the rod exits from the hinge holes.
NOTE: The door of the FUSION must always remain closed during operation.

Blowers
The FUSION wood burning fireplace insert is equipped with two AC centrifugal compact fans on either side of the surround (electrical rating: 115V, 60Hz, and 19W). Please refer to Section 4.6 for more information on the blower kit.

Optional Fresh Air Adaptor
The Optional Fresh Air Kit allows for exterior air (outdoors) to be drawn into the fireplace during operation of the unit. Note that a 4 inches duct is required for the installation (item ordered separately). Refer to Section 4.7 for installation instructions. Contact your local building official regarding mandatory fresh air kit installations within your area.
CAUTION: Only a fresh air kit provided by SUPREME FIREPLACES INC. can be installed onto the fireplace. Substituting the fresh air kit may result in overheating and will void the warranty.

Adjustable Legs
The FUSION insert is supplied with three adjustable legs (see Figure 2-5) to allow adjustment of the height if the surround is not flushed with the wall of the masonry fireplace.

Liner Adaptor
The FUSION Liner Adaptor (IN1110) (Figure 2-6) is a component that comes with the FUSION and is required to connect a 5” stainless steel liner to the FUSION insert.

Surround
Optional surrounds are available for the FUSION wood burning insert series:

NOTE: SUPREME FIREPLACES INC. reserves the right to alter the dimensions of the surrounds without prior notice.

Adjustable Circulating Chamber
The adjustable circulating chamber (Patent: US 9,488,375 B2) is a standard component of the FUSION insert (see Figure 2-9). It is designed to prevent heat escaping from the existing chimney and allows for an optimal flow and heat transfer. The width is adjustable from 28” to 32” for the Fusion 18 and 32” to 38” for the Fusion 24. The front height is adjustable from 21.75” to 24.75” with the rear height fixed at 21.75” for the Fusion 18. The front height is adjustable from 23.75” to 26.75” with the rear height fixed at 23.75” for the Fusion 24. The hole for the stainless steel liner is adjustable by 2” (front to rear).
NOTE: The circulating chamber requires minimal adjustments. Please refer to Section 3.3 for detailed instructions.

Metal Tag

• The Metal Tag is found on the front of the metal shipping crate and indicates that alterations have been made to the masonry fireplace to accommodate the FUSION insert. The metal sheet having the Metal Tag is to be installed with two screws at the Bottom of the Circulating Chamber. The Bottom of the Circulating Chamber should have the side with the Metal Tag installed face up so the Metal Tag is visible if the firebox were to be removed.
• The Metal Tag reads as follows:
• This fireplace has been altered to accommodate a fireplace insert and should be inspected by a qualified person prior to re-use as a conventional fireplace.
• Ce foyer a été modifié afin d’y insérer un foyer encastrable et doit être inspecté par une personne qualifiée avant sa réutilisation comme foyer conventionnel.

Note that a mantel cannot be installed below the minimum clearance of 34.5” (from the bottom of the mantel to the base of the unit).

OPERATION INSTRUCTIONS

WARNING: READ THE OWNER’S MANUAL CAREFULLY BEFORE USING YOUR FIREPLACE INSERT. The FUSION is not intended to serve as a primary source of heat. A primary source of heat must be available in the home that the FUSION is installed in. Supreme is not responsible for heating costs related to other sources of heat.

Fuel

• The FUSION is designed to burn natural wood only. Higher efficiencies and lower emissions generally result when burning air dried seasoned hardwoods (moisture content below 20%), as compared to softwoods or to green or freshly cut hardwoods. The following are a few signs indicating that firewood is sufficiently dry for use: (a) cracks on the ends and surface of the logs, (b) lighter in weight, and (c) color (yellow/grey). It is recommended to use a moisture meter with pin sensors for determining accurately the moisture content of firewood (read manufacturer’s instruction manual before operating). The optimum log length is 16-18 inches for the FUSION 18 and 20-22 inches for the FUSION 24, preferably split in halves or quarters and left to dry under a cover or away from external elements for a minimum of one year prior to use. Use good quality dry cordwood only. DO NOT burn garbage, lawn clipping, yard waste, materials containing rubber (including tires), materials containing plastic, waste petroleum products, paints, paint thinners, asphalt products, materials containing asbestos, construction debris, demolition debris, railroad ties, pressure-treated wood, manure, animal remains, coal, salt water driftwood or other previously salt water saturated materials, unseasoned wood, paper products, cardboard, plywood, particle boards, or other foreign materials in this product. The prohibition against burning these materials does not prohibit the use of fire starters made from paper, cardboard, saw dust, wax and similar substances for the purpose of starting a fire in an affected wood heater. Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke. Do not over fire the FUSION fireplace insert. Over firing will damage the fireplace, is hazardous and will void the warranty. NOTE: Gas logs cannot be installed in the FUSION fireplace insert.
  WARNING: Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in this unit. Keep all such liquids well away from the fireplace insert while it is in use.

• Ecological or compressed logs could contain chemical additives that are not tested and approved to be used with the FUSION. Using them will overheat and damage the fireplace and void the warranty.
  WARNING: Do not keep the door open while the fireplace is in operation.
  CAUTION: Store fuel away from the heater; refer to Section 3.7 for required clearances.

First Fires
For the first 3 fires, burn a maximum of 3 logs at the medium to low burn rate (refer to Section 4.3) to allow for proper conditioning of the unit. Due to oil residues and the curing of the paint of the fireplace, it is normal to smell an odor for the first fires of the FUSION. Open a window or a door near the fireplace insert to ventilate the house during the first fires. Oil residues may cause light smoking.

Operating the Combustion Air Control

• The burn rate and the heat output are related to the amount of air entering the firebox. The combustion air control of the FUSION has two components: the Activator and the Burn Rate Selector. When starting the fire or when adding a new charge of wood, the fireplace needs additional air in order to establish a good fire. When the wood starts to burn properly, the amount of air can be reduced depending on the heating requirements.
• The left combustion control lever is the Activator. When starting a fire or adding a new load of wood, the Activator must be pushed in to allow maximum air to enter the firebox. The right combustion control lever is the Burn Rate Selector. The Burn Rate Selector can slide sideways to achieve different burn rates. When the Burn Rate Selector is positioned to the left, a maximum burn rate is achieved and when it is positioned to the right, a minimum burn rate is set. Keeping the Burn Rate Selector to the right will burn the wood slower. Keeping the Burn Rate Selector to the left will provide a stronger fire and keep the glass of the fireplace cleaner for longer. Adjust the burn rate according to your heating requiremments and the quality of your wood. The combustion air control will automatically and gradually close the primary air source to the selected burn rate setting (right lever) with the presence of heat to maximize the burn time.
  • NOTE: The Burn Rate Selector can remain at the same setting if the burn rate is satisfactory. However, the Activator must be pushed in when starting a fire or when adding a new load of wood.
  • WARNING: The combustion air openings should never be obstructed.
  • WARNING: Never manipulate the Combustion Air Control with bare hands as it gets hot when the FUSION is in operation. Use the Cold Hand Key to adjust the Combustion Air Control.
  • 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.

Starting a Fire

The FUSION has patented technologies and innovative features that make starting a fire quick and easy. Before starting a fire, assure that all the safety precautions mentioned in the owner’s manual are being respected. The following instructions describe starting a fire in FUSION fireplace using a “top-down” approach, which results in a cleaner, more efficient, and longer burn:

1. FUSION 18

   • Place two logs in the firebox. The logs should sit directly on the hearth. Do not use a fireplace grate.
   • Place a third log at angle above the two logs of step a).
   • Place a fourth log above the logs of step a) and step b) (tilted upwards), which will result in a “pocket” at the center of the firebox.
   • Push the left combustion control lever (the Activator) inwards.
   • Slide the right combustion control lever (the Burn Rate Selector) to the desired burn rate. Positioning the Burn Rate Selector towards the left is for maximum burn rate and towards the right is for minimum burn rate.
   • Place and ignite a firestarter within the “pocket”. Make sure that the firestarter is visible from the opening (facing the front) and directly below the logs of step b) and step c).
   • Once the firestarter is well lit, close the door. Do not leave the door open for more than 2 minutes.

2. FUSION 24

   • Place small to medium size logs on the hearth of the firebox in the north-south direction. The logs should sit directly on the hearth with adequate space between them to allow for proper air flow. Do not use a fireplace grate.

   • Place kindling wood or small logs on top of the logs from step a). Keep a good distance from the top layer of the kindling/logs and the baffle system (approximately 3 inches).

   • Push the left combustion control lever (the Activator) inwards.

   • Slide the right combustion control lever (the Burn Rate Selector) to the maximum burn rate position (towards the left).

   • To achieve a “top-down” combustion, ignite the top layer of kindling/logs. A firestarter can be used to facilitate ignition.

   • Once the top layer has properly ignited, close the door. Do not leave the door open for more than 2 minutes.

   • CAUTION: The wood should be placed away from the door to avoid damage to the glass.

   • WARNINGS: Over firing the unit may result in overheating and can damage the fireplace and/or result in fire hazards. The maximum firewood load must not exceed 4 medium sized logs (approximately 25 pounds) for the FUSION 18 and 5 medium sized logs (approximately 30 pounds) for the FUSION 24. This fireplace has been designed to burn with the door closed. When the fireplace is being used, the door should remain closed at all times. Failing to do so is a safety hazard, will damage the fireplace and void the warranty.

   • WARNING: Do not use fire accelerants to rekindle the fire if the first attempt to start the fire failed. Do not open the door. Simply reactivate the Activator by pushing it inwards.

   • IMPORTANT: Sufficient air exchange is necessary for the fireplace to operate properly. Air is required in order to maintain the combustion of the fireplace. If the house is airtight, the fireplace may not function properly. If the fireplace is deprived of air, it will be necessary to provide a source of fresh air into the dwelling. This may be done by using an air exchanger unit or simply by opening a window or a door near the fireplace partially for a few minutes. Make sure that other equipment such as the kitchen exhaust fans or oil central heating systems does not affect the fireplace functionality. Large return ducts of central heating systems located in the same room as the fireplace may affect the proper functioning of the unit and may cause smoking.

Adding a New Load of Wood

WARNING: Open the door to reload only when the wood has been reduced to embers, otherwise there is a risk of smoke infiltration into the house.
When the wood has been reduced to embers and there’s no visible flame, you may add a new load.

• FUSION 18
  • Crack the FUSION door open and wait a few moments before opening the door completely.
  • Use your fireplace tools to gather the remaining embers at the center of the firebox.
  • Activate the Activator by pushing it in.
  • Once the embers begin to glow red, add the new load of wood in the firebox.
  • Keep the door of the FUSION slightly unlatched until you see a flame in the firebox. Never leave the FUSION door unlatched without constant supervision.
  • Completely latch the FUSION door.
• FUSION 24
  • Crack the door open and wait a few moments before opening the door completely.
  • Use your fireplace tools to gather the remaining embers at the center of the firebox.
  • Position the Burn Rate Selector to the desired setting and activate the Activator by pushing it in.
  • Once the embers begin to glow red, add the new load of wood in the firebox.
  • Place the first row of wood (2 pieces for maximum burn rate or 3 pieces for minimum/medium burn rate) in the north-south direction on the center of the hearth, with an adequate space between the logs.
  • Place the second row of wood (3 pieces), in the east-west direction with an adequate space between the logs.
  • Keep the door of the FUSION slightly unlatched until you see a flame in the firebox. Never leave the door unlatched without constant supervision.
  • Completely latch the door.
    Assure that a flame is maintained. Avoid wood smoldering on top of embers as this will result in a dirty glass, excessive emissions, chimney creosote buildup and poor heat output. If wood is smoldering, ensure the Activator has been activated and unlatch the door slightly with supervision until a flame has been maintained.

Blower Kit

• A blower kit is included in the FUSION fireplace insert, which comprises of two compact blowers (120V, 60Hz, 1.1A) mounted at the bottom on either side of the firebox and a heat sensory thermodisk. The kit includes a variable speed control to adjust the speed of the fans. Do not install a substitute kit as this may result in overheating and risk of fire.
  CAUTION: Do not route the power cord under or in front of the unit, on hot surfaces, and on sharp edges.
  NOTE: Disconnect the power supply when accessing any electrical components in the FUSION insert fireplace.

• Once the power cord has been plugged to the nearest 115V outlet, the fans will turn on and turn off automatically. When the insert gets hot and the thermodisk reaches 95°F, the fans will turn on. The average time it takes for the fans to activate is 30 to 45 minutes after starting a fire as explained in this manual (Section 4.4 Starting a Fire). The fans will turn off once the insert has cooled down and the thermodisk reaches 85°F. Note that the response time of the blowers can be adjusted by loosening the screws and sliding the thermodisk mounting bracket further (longer delay) or closer (shorter delay) from the firebox (see Figure 4-2). The speed of the fans can be adjusted with the variable speed control (clockwise to reduce speed and counter-clockwise to increase). To manually shut-off the blower kit, turn the counter-clockwise until the knob “clicks”.

Fresh Air Kit (Optional)

• Sufficient air exchange is necessary for the fireplace to operate properly and to maintain a good combustion. In an airtight household, the fireplace may not function as designed due to a lack of air; it is therefore recommended to install the fresh air kit in such cases. The fresh air system is an optional kit intended to bring combustion air into the fireplace from an exterior source.
• Note that the FUSION is designed to use a minimum amount of air during operation. Using an air exchanger or simply opening a nearby window/door during the ignition of the unit will achieve a similar result as the fresh air kit. When the fireplace is idle, there is no air escaping from the house through chimney. Consult a local authority having jurisdiction (such as the fire department, the municipal building department, the fire prevention bureau) to determine if it is mandatory to install a fresh air kit in your area.

General Notes:
The outside air kit should be installed according to the following guidelines:

• The air duct must have an inner diameter of 4 inches.
• The length of the air duct should not exceed 25 feet.
• The duct should not be elevated more than 10 feet from the base of the unit.
• Fresh air must come from the outside and not from another room or the attic.
• The outside register must be away from automobile exhaust fumes, gas meters, or other vents.
• Avoid installing the air register where it will likely be covered by snow or exposed to strong winds.
• The air register can be installed above or below the level of the fireplace.
• Use the SUPREME FIREPLACES INC. Fresh Air Adapter (ADP4_IN) provided with the unit.
• Use the SUPREME FIREPLACES INC. Fresh Air Kit (PEA4).

Installation:

1. Cut 4 ½” diameter hole on the exterior wall of an ideal location.
2. Install the air register on the exterior wall.
3. Remove the 1.625’’ knockout from side wall of the circulating chamber and insert the fresh air adapter (ADP4_IN).
4. Secure the fresh air adapter to the side of the fireplace using two screws.
5. Install the air duct and secure it with worm gear clamps.

Barbecue Grill (Optional)

• A removable swivelling barbecue grill can be installed into the FUSION insert as an option. When operating the FUSION, the barbecue grill should be leaning against the rear wall of the firebox, in the upright position. The grill swivels to the horizontal position above the bed of embers for cooking purposes. The barbecue grill is removable by lifting the hinge and pulling forward.
• Useful Tips and Recommendations:
  • Schedule cooking in the FUSION; approximately 4 to 6 hours is needed before an ideal bed of embers is produced from the load.
  • Cook with indirect heat (convection); move the coals along the walls of the firebox.
  • Keep the door closed while cooking.
  • Use the left handle of the Combustion Air Control, the Activator, (Section 2.3) to regulate the temperature of the unit while cooking. To avoid flare-ups, slide the Burn Rate Selector to the right (minimum setting) and pull the activator towards you if it hasn’t already been retracted.
  • Cook fish on a cedar plank.
  • Greasy food may cause smoking.
• Do not use the FUSION insert as a primary cooking appliance. This feature is designed for occasional grilling during the winter and cooking during power failures. Foods that are commonly grilled in a conventional barbecue can be cooked in the FUSION insert. The intense heat from the next combustion cycle cleans the grill and the unit of any cooking residue.
• DISCLAIMER: SUPREME FIREPLACES INC. is not responsible for the quality nor the outcome of the food cooked in the FUSION.

TROUBLESHOOTING

Backdraft / Smoking

• Draft is the force created by a difference in pressure, which moves air from the appliance up through the chimney. It is important to operate the FUSION with proper draft to ensure optimal performance of the unit. Draft is depended on the length of the chimney, local geography, nearby obstructions and other factors. Proper draft results in an upwards flow through chimney, which prevents smoke infiltrating into the house during operation of the unit. As the temperature of the unit and chimney rises during combustion, the draft consequently increases due to a higher difference in pressure.
• In contrast, backdraft is air flow from the chimney into the house, which results in smoke infiltration from the appliance and/or the chimney joints during operation. The unit is experiencing backdraft if air is flowing out from the exhaust of the baffle system (within the firebox). Backdraft is commonly caused by fans around the house (such as in the kitchen and bathrooms) simultaneously in operation, insufficient length of the chimney (less than 15 feet), inadequate ventilation, or a blocked chimney. Refer to the following suggestions to eliminate backdraft:
  • Close any fans operating around the house (specifically for the duration of ignition).
  • Clean the chimney of any obtrusions (when the unit is cold).
  • Open one window or one door near the FUSION.
  • Heat the chimney by burning newspaper near the exhaust of the baffle system.

Over Firing
The appearance of a red glow on the exterior of the firebox (top and sides) and/or on the flue is a sign of over firing. Excess air entering the firebox, over fueling, or an abnormal strong draft causes the unit to reach drastic temperatures from an uncontrollable combustion. Over firing is a safety hazard and may result in permanent damage to the unit. In the occurrence of over firing:

• Make sure the FUSION door is properly closed.

• Manually close the Combustion Air Control by pulling the Activator (left lever).

• Turn on the blower to the maximum speed. The red glow on the exterior of the firebox and/or the flexible liner should gradually disappear.
  WARNING: Do not touch hot surfaces with bare hands. Always wear heat protecting gloves and use fireplace tools.
  Guideline to avoid over firing:

  • Always keep the door closed during operation.
  • Inspect regularly the door gasket/glass and replace accordingly.
  • Always operate the unit with the chimney sweeping cap in position, blocking the hole in the baffle (Refer to Section 2.7 for Chimney Sweeping Cap location).
  • Never load more than 25 lbs for the FUSION 18 and 30 lbs for the FUSION 24 of wood at a time.
  • Ensure that there is no excess draft.
    WARNING: Failure to follow the above guideline will void the warranty. Over firing is a safety hazard, can cause irreversible damages to the FUSION and will void the warranty.

MAINTENANCE

Disposal of Ashes
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 on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial on soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have been thoroughly cooled. CAUTION: Always wear heat resistant gloves when removing the ashes from the firebox.

• Let the firebox cool to ambient temperature before removing the ashes. It is recommended to remove the ashes once the bed has exceeded a height of 4 inches.
• Slowly open the door to prevent ashes from coming into the room.
• Place an ash bucket (metal container) near the fireplace, onto the non-combustible hearth.
• Using a shovel and brush, remove the bulk of the ashes from the firebox into the ash bucket. Note that it is not necessary to keep a thin bed of ashes for the next fire.
• Store the ash bucket (with the tight-fitting lid) on a non-combustible surface, away from any combustible materials, pending final disposal.

Chimney Maintenance
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 vapor condenses 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 hot fire. The chimney connector and chimney burning wood or coal should be inspected at least once every two months during the heating season to determine if creosote buildup has occurred. Note that continuously operating the unit with green or wet wood will result in premature creosote buildup. Never use chemical cleaners for your chimney.
WARNING: In the case of a chimney fire: 1) close the door of the fireplace; 2) set the burn rate of the Combustion Air Control to minimum (Section 4.3); 3) call the local fire department (if assistance is needed); 4) use a dry chemical fire extinguisher (baking soda or sand) to control the fire.
CAUTION: Never use water to extinguish a fire as it may result to dangerous steam explosions. Do not use the unit until the chimney is inspected and repaired (if needed) by a qualified technician.
NOTE: Do not clean the chimney when the unit is in operation/hot. Follow the instructions below for sweeping the chimney of a FUSION fireplace insert:

• Open the door of the unit.
• From within the firebox, displace the chimney sweeping cap located in the baffle by lifting and moving it to the side.
• Close the door of the unit.
• Using an appropriate sized chimney sweeping brush, clean the chimney from any creosote buildup and other residues.
• Remove all the fallen/loose creosote/residues from the firebox and baffle system (a shop vacuum cleaner can be used for a thorough cleaning).
• Place back the chimney sweeping cap.
  CAUTION: Operating the unit without the chimney sweeping cap in position will result in over firing and void the warranty.

Cleaning of Glass

• It is recommended to clean the glass door with a soft cloth, damped with a non-abrasive solution, such as soap and water.
  CAUTION: Cleaning the glass with an abrasive solution will result in surface scratches, reducing glass transparency and resistance to impacts.

• The glass of the door may be cleaned with commercial products intended for fireplaces and stoves. After cleaning the glass, remove any remaining solutions with a wet cloth to avoid chemical reactions at elevated temperatures (“cloudiness’’ on the surface of the glass).
  CAUTION: Do not apply commercial cleaners onto any painted surfaces as discoloration/peeling may occur.
  NOTE: Never clean the glass when the unit is in operation or hot.

Replacement of Door Gasket

• SUPREME FIREPLACES INC. assembles heat resistant graphite coated gaskets on the doors of all products, allowing for a proper seal of the unit at extreme temperatures (up to 538 oC / 1000oF). It is recommended to perform a weekly visual check on the condition of the ¾” gasket to ensure proper operation of the unit. The ¾” gasket of your door needs to be replaced when 1) the fibers of the gasket are coming loose and 2) the gasket is disintegrating. Failure to replace a gasket under the mentioned conditions can cause irreversible damage to the unit due to over firing. Refer to the following instructions for replacing the ¾” gasket:
  • Order the replacement kit for the FUSION ¾” door gasket (GSK_75_7).
  • Remove the door from the firebox and place it face down on a soft surface. NOTE: Rotate the handle to permit proper placing.
  • Cover all painted surfaces of the door to avoid damages.
  • Using a wedging tool or flat head screwdriver, gently remove the old ¾” gasket (along with the old silicone) from the door framing.
  • Apply a bead of high temperature silicone along the groove of the metal brackets.
  • Place the new ¾” gasket around the door framing and cut any excess gasket with scissors. NOTE: It is recommended to tape the extremity of the gasket for a cleaner result.
• Give significant amount of time to allow the silicone to cure before reinstalling the door onto the firebox. A slight resistance is expected when closing the door with the new ¾” gasket; the door will close normally after the gasket has taken proper shape.
  NOTE: Replacing the gasket with a non-conform substitute material may overheat the unit and void the warranty.

Replacement of Glass
SUPREME FIREPLACES INC. uses a high quality 5mm thick Pyroceram III / Keralite ceramic glass that can withstand temperatures up to 1300oF. It is recommended to perform a weekly visual check for any damages or cracks on the glass.
WARNING: Avoid striking the glass and slamming the door shut. Never operate the unit with a broken or damage glass.
