Encore EU dimensions 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove Installation Before you begin an installation, be sure that: • Your stove and chimney connector will be far enough from combustible materials to meet all tested clearance requirements. • The floor protector is large enough and is constructed properly to meet all tested requirements. • You have all necessary permits from local authorities. Your local building official is the final authority for approving your installation as safe and determining that it meets local and state codes. The metal label permanently attached to the back of every Vermont Castings’ stove indicates the stove has been tested and meets current standards. Clearance and installation information also is printed on the label. When the stove is installed according to the information both on the label and in this manual, local authorities in most cases will accept the label as evidence that the installation meets codes and can be approved. However, codes vary in different countries. Before starting the installation, review your plans with the local building authority. Your local dealer can provide any additional information needed. Important: Failure to follow these installation instructions may result in a dangerous situation, including a chimney or house fire. Follow all instructions exactly, and do not allow makeshift compromises to endanger property and personal safety. All local regulations, including those referring to national and European standards need to be complied with when installing this stove. Outside Air In some modern, super-insulated homes, there is inadequate air for combustion because of insufficient air infiltration into the building. Such air enters a home through unsealed cracks and openings. Exhaust fans for kitchen or bath can compete with the stove for available air and compound the problem. When poor draft is caused by a low infiltration rate, opening a ground floor window on the windward side of the house and in the vicinity of the stove will usually alleviate the problem. For appliances with power outputs above 5 kW, a permanently open air vent is required by Section 2 of Document J. Air inlet grilles should be positioned so they will not be blocked. Refer to local and national codes for recommended configurations. Pressure variations within the house do not affect a stove equipped with an outside air supply, and improved stove performance often results. An Outside Air Adapter Kit for the Encore is available from your local Vermont Castings dealer. Chimney Height Altitude affects chimney performance. When using a 152 mm (6”) flue collar on the Encore NC, refer to Figure 2 for suggested chimney heights at various altitudes. Chimney height should be measured from the flue collar to the top of the chimney. The recommended minimum chimney height is 4.9 m (16’). 30 Height (ft.) safety NOTICE: IF YOUR ENCORE IS NOT PROPERLY INSTALLED, A HOUSE FIRE MAY RESULT. TO REDUCE THE RISK OF FIRE, FOLLOW THE INSTALLATION INSTRUCTIONS.

The chimney and chimney connector must be in good condition and kept clean. If you use an existing masonry chimney, it must be inspected to ensure it is in a safe condition before the stove is installed. Your local professional chimney sweep, building inspector, or fire department official will be able to inspect the chimney or provide a referral to someone who can. The flue and chimney design must meet requirement J2, Part J of the building regulations 2000 (Combustion Appliances and Fuel Storage Systems). A prefabricated doublewall insulated chimney Prefabricated Chimneys These should be an internal diameter of 150 mm (6”) and be of the twin wall insulated construction that has been approved for solid fuel use (e.g. Rite Vent ICS of ICID Lite Chimney Systems). Diameters over 200 mm (8”) are not recommended due to the large cross-section causing excessive cooling of the flue gases. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. Chimney Size An Encore with an 203 mm (8”) flue collar is approved for venting into a masonry chimney with a nominal flue size of 203 x 203 mm (8” x 8”) or 203 x 305 mm (8” x 12”), and into a round flue with nominal flue size of 203 mm (8”). An Encore with a 152 mm (6”) flue collar is approved for venting into a masonry chimney with a nominal flue size of 203 x 203 mm (8” x 8”), and into a round flue with nominal flue of 152 mm (6”). NOTE: When installed with a 152 mm (6”) flue collar, the Encore may not be operated with the front doors open. A tile-lined masonry chimney ST241 Fig. 3 Approved chimney types. Masonry Chimneys An inspection of the chimney must confirm that it has ST241 a lining. Do not usechimney an unlined types chimney. The chimney 12/13/99 djt mortar, other signs of should have no cracks, loose deterioration, and blockage. Repair any defects before the chimney is used with your stove. Unused openings in an existing masonry chimney must be sealed with masonry to the thickness of the chimney wall, and the chimney liner should be repaired. Openings sealed with pie plates or wallpaper are a hazard and should be sealed with mortar or refractory cement. In the event of a chimney fire, flames and smoke may be forced out of these unused thimbles. The chimney should be thoroughly cleaned before use. A newly-built masonry chimney must conform to the standards of your local building code or, in the absence of a local code, to a recognized national code. Masonry chimneys must be lined, either with code-approved masonry or pre-cast refractory tiles, stainless steel pipe, or a code-approved, “poured-in-place” liner. The chimney’s clean-out door must seal tightly. 30003845 Whatever the flue collar size, an Encore may be vented into larger chimneys as well. However, chimneys with liners larger than 203 x 305 mm (8” x 12”) may experience rapid cooling of smoke and reduction in draft, especially if the chimneys are located outside the home. These large chimneys may need to be insulated or have their flues relined for proper stove performance. Accessories to help make the connection between stainless steel chimney liners and your Encore are available through your local dealer. Chimney Connector Guidelines A chimney connector is the double-wall or single-wall pipe that connects the stove to the chimney. The chimney itself is the masonry or prefabricated structure that encloses the flue. Chimney connectors are used only to connect the stove to the chimney, as in Figure 5. Connecting Flue Pipes Connector pipes should meet the requirements of the building regulations. This can be achieved by the use connecting fluepipes included in the following categories: a)Vitreous enamelled steel pipe complying with BS 6999: 1989 (1996); b)Pipes made from stainless steel as descirbed in BS EN 1008-1:1995 grades 1.4401, 1.4404, 1.4432 or 1.4436 with flue wall thickness of at least 1 mm; c)Mild steel fluepipes complying with BS 1449: Part 1: 1991, with a flue wall thickness of at least 3 mm; d)Cast iron fluepipes complying with BS 41: 1973 (1998). Encore® 1450CE Non-Catalytic Woodburning Stove Flue Pipes with a spigot and socket joint should be fitted with the socket facing upwards, to contain condensates and moisture within the flue. Joints should be made gas tight using proprietary jointing accessories, or, where appropriate, by packing joint with noncombustible rope and fire cement. Double-wall connectors must be tested and listed for use with solid-fuel burning appliances. Single-wall connectors should be made of 24 gauge or heavier steel. Do not use galvanized connector; it cannot withstand the high temperatures that can be reached by the stove’s exhaust gases, and may release toxic fumes under high heat. The connector may be 152 mm (6”) or 203 mm (8“) in diameter. If possible, do not pass the chimney connector through a combustible wall or ceiling. If passage through a combustible wall is unavoidable, refer to the section on Wall Pass-Throughs. Do not pass the connector through an attic, a closet or similar concealed space. The whole connector should be exposed and accessible for inspection and cleaning. In horizontal runs of chimney connector, maintain a distance of 610 mm (24”) from the ceiling. Keep it as short and direct as possible, with no more than two 90° turns. Slope horizontal runs of connector upward 6 mm per meter (1/4” per foot) going from the stove toward the chimney. The recommended maximum length of a horizontal run is 914 mm (36”), and the total length should be no longer than 2.4 m (8’). In cathedral ceiling installations, extend the prefabricated chimney downward to within 2.4 m (8’) of the stove. Wear gloves and protective eyewear when drilling, cutting or joining sections of chimney connector. Single-wall Chimney Connectors • Begin assembly at the flue collar of the stove. Insert • the first crimped end into the stove’s flue collar, and keep each crimped end pointing toward the stove. (Fig. 4) Using the holes in the flue collar as guides, drill 3 mm (1/8”) holes in the bottom of the first section of chimney connector and secure it to the flue collar with three #10 x 1/2” sheet metal screws. Secure each joint between sections of chimney connector, including Fig. 4 the crimped end telescoping joints, with at of the connector points ST242 least three (3) sheet metal towardChimney connector stove. 12/13/99 djt screws. The pre-drilled holes in the top of each section of chimney connector serve as guides when you drill 3 mm (1/8”) holes in the bottom of the next section. • Secure the chimney connector to the chimney. In• structions for various installations follow. Be sure the stove and chimney connector are installed at the correct distances from nearby combustible materials as per tested clearance. Refer to Encore Clearance Diagrams. NOTE: Special slip pipes and thimble sleeves that form telescoping joints between sections of chimney connector are available to simplify installations. They often eliminate the need to cut individual connector sections. Consult your local dealer about these special pieces. Double-wall Chimney Connectors Information on assembling and installing double-wall connectors is provided by the manufacturer of the double-wall pipe. Follow the manufacturer’s instructions exactly as you assemble the connector and attach it to the stove and chimney. Using chimneys and connectors from the same manufacturer makes the assembly and installation straightforward. NOTE: For installations using double-wall connectors, minimum clearances must conform to the listed clearances in the clearance chart on Page 13. If the Encore is equipped with the 203 mm (8”) flue collar, an oval-to-round adapter will be needed. Doublewall oval-to-round adapters are available from some manufacturers. Your local dealer can help you select the right connector. Securing the Single-wall Connector to a Prefabricated Chimney Follow the installation instructions of the chimney manufacturer exactly as you install the chimney. The manufacturer of the chimney will supply the accessories to support the chimney, either from the roof of the house, at the ceiling of the room where the stove is installed, or from an exterior wall. Special adapters are available from your local dealer which connect the prefabricated chimney to the chimney connector. The top of such adapters attach directly to the chimney or to the chimney’s ceiling support package, while the bottom of the adapter is screwed to the chimney connector. These adapters are designed so the top end will fit outside the inner wall of the chimney, and the bottom end will fit inside the first section of chimney connector. When assembled in this way, any soot or creosote falling from the inner walls of the chimney will stay inside the chimney connector. 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove Chimney Flue Elbow Flue Liner To install a thimble sleeve, slide it into the breech until it is flush with the inner flue wall. Do not extend it into the actual flue passage, as this could interfere with the draft. Slip Pipe Thimble Standard Connector Oval to Round Adapter The thimble sleeve should protrude 25-51 mm (1-2”) into the room. (Fig. 6) Use furnace cement and thin gasketing to seal the sleeve in place in the thimble. Secure the chimney connector to the outer end of the sleeve with sheet metal screws. Flue Collar ST492 Fig. 5 An exploded view of the chimney connection in a freestanding masonry installation. ST492 Defiant Securing the Single-wall Connector to a freestanding Masonry Chimney installation 11/00 Both freestanding masonry chimneys and fireplace masonry chimneys may be used for your installation. Thimble Sleeve Chimney Connector Flue Keep sleeve end flush with flue tile ST243 Fig. 6 The thimble, made of either ceramic or metal, must be cemented securely in place. Freestanding Installations If the chimney connector must pass through a combusST243 tible wall to reach the chimney, follow the recommenconnection dations in thethinble Wall Pass-Through section later in this 12/13/99 djt manual. The opening through the chimney wall to the flue (the “breech”) must be lined with either a ceramic or metal cylinder, called the “thimble”, which is cemented securely in place. Most chimney breeches incorporate thimbles, but the fit must be snug and the joint between the thimble and the chimney wall must be cemented firmly. 30003845 A special piece called the “thimble sleeve,” slightly smaller in diameter than standard connectors and most thimbles, will facilitate the removal of the chimney connector system for inspection and cleaning. Thimble sleeves are available from your local dealer. Without a thimble, a suitable length of chimney connector can be extended through the breech to the inner face of the flue liner, and cemented securely in place. Additional pieces of connector are then attached with sheet metal screws. Fireplace Installations The chimney connector may be connected to the chimney above the fireplace opening or through the fireplace. Above the Fireplace The Encore may be connected to a chimney above a fireplace opening. (Fig. 7) In such installations, the stove is positioned on the hearth in front of the fireplace and the chimney connector rises from the stove top and then angles ninety degrees back into the chimney. The chimney liner should extend to the point at which the chimney connector enters the chimney. If the chimney connector from your installation enters the chimney above a fireplace, follow all the guidelines mentioned above for freestanding installations. In addition, give special consideration to the following points: • Check the clearance between the stove and the chimney connector, and any combustible trim or the mantel. Use the necessary combination of mantel, trim, and connector heat shields to achieve the required clearances. • Check the clearance between the chimney connector and the ceiling. If no heat shields are used, the clearance should be at least 610 mm (24”). To find out how much this clearance may be reduced with heat shields, refer to the clearance chart on Page 13. • The fireplace damper must be sealed to prevent room air from escaping up the flue. However, it must be possible to re-open the damper to inspect or clean the chimney.

You’ll find the required safe clearances for Encore fireplace installations on Page 12 and Figure 14. Floor protection requirements also apply to fireplace installations. This information is on Page 19. Wall Pass-Throughs Whenever possible, design your installation so the connector does not pass through a combustible wall. If you are considering a wall pass-through in your installation, check with your building inspector before you begin. Also, check with the chimney connector manufacturer for any specific requirements. Accessories are available for use as wall passthroughs. If using one of these, make sure it has been tested and listed for use as a wall pass-through. Figure 9 shows one recommended method. All combustible material in the wall is cut away from the single-wall connector to provide the required 305 mm (12”) clearance. Any material used to close up the opening must be noncombustible. ST494 Fig. 9 An approved wall pass-through for Canada. Three other methods are also approved by the NFPA: ST494 • Using a section ofsteel double-wall chimney with a wallcombustibles. pass thru 229 mm (9”) clearance to 11/00 • Placing a section of chimney connector inside a ventilated thimble, which in turn is separated from combustibles by 152 mm (6”) of fiberglass insulating material. • Placing a section of chimney connector inside a section of 229 mm (9”) diameter, solid-insulated, factory-built chimney, with 51 mm (2”) of air space between the chimney section and combustibles. Figure 10 shows one method of passing a connector through a wall. All combustible material in the wall is cut away to provide the required 457 mm (18”) clearance 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove for the connector. The resulting space must remain empty. A flush-mounted sheet metal cover may be used on one side only. If covers must be used on both sides, each cover must be mounted on noncombustible spacers at least 25 mm (1”) clear of the wall. Your local dealer or your local building inspector can provide details for other approved methods of passing a chimney connector through a combustible wall in your area. Do not connect an ENCORE to any air distribution duct or system. Floor Protection for Fireplace Installations Do not assume that your fireplace hearth is completely noncombustible. Many fireplace hearths do not meet the “completely noncombustible” requirement because the brick or concrete in front of the fireplace opening is supported by heavy wood framing. (Fig. 11) Because heat passes through brick or concrete readily, it can easily pass through to the wood. As a result, such fireplace hearths can be a fire hazard and are considered a combustible floor. Hearths This appliance must be installed on to hearth that meets the requirements of Part J of the Building Regulations 2000 (Combustion Appliances and Fuel Storage Systems). This can be achieved by ensuring that the hearth is constructed and sized in accordance with the guidelines included in section 2 of approved document ‘J’. The size and clearances of the hearth are as follows: The constructed hearth should be constructed in accordance with the recommendations in document J, and should be of minimum width 840 mm and minimum depth 840 mm (if a free standing hearth b) above) or a minimum projection of 150 mm from the jamb (if a recessed hearth a) above). Costructional Hearth Dimensions as below Appliance Doors Hearth Surface Free of Combustible Material At least 150 mm Perimeter should be clearly marked e.g. edge of superimposed hearth At least 300 mm a) Fireplace recess Fig. 10 Noncombustible hearth surface dimensions. Wood framing requires protection from radiant heat ST247e Fig. 11 Combustible supporting timbers may lie beneath fireplace hearths, requiring additional floor protection.

Fireplace installations also have special clearance requirements to the side walls, side decorative trim, and fireplace mantel. This information follows in the section on Fireplace and Mantel Trim Shields. 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove Keep the Stove a Safe Distance from Surrounding Materials Both a stove and its chimney connector radiate heat in all directions when operating, and dangerous overheating of nearby combustible materials can occur if they are too close to the heat. A safe installation requires that adequate clearance be maintained between the hot stove and its connector and nearby combustibles. Clearance is the distance between either your stove (measured from the bottom edge of the stove’s top plate) or chimney connector, and nearby walls, floors, the ceiling, and any other fixed combustible surface. Your stove has special clearance requirements that have been established after careful research and testing to both US and European standards. These clearance requirements must be strictly observed. In addition, furnishings and other combustible materials must be kept away from the stove. In general, a distance of 1219 mm (48”) must be maintained between the stove and moveable combustible items such as drying clothes, furniture, newspapers, firewood, etc. Keeping those clearance areas empty assures that nearby surfaces and objects will not overheat. Summary of Clearances Minimum recommended side clearances to noncombustible surfaces 125 mm (5”). Minimum recommended rear clearance to noncombustible surfaces 50 mm (2”). NOTE: The minimum thickness of solid noncombustible materials is specified in section 2 of Document ‘J’, in relation to the clearance of the appliance from the surface. As a general rule, the thickness of solid noncombustible material forming the recess of a fireplace is a minimum of 200 mm. Minimum rear clearance from combustible walls (e.g. timber framed or studded walls) 750 mm (29Z\x”) measured from the rear edge of the stove top. (Fig. 12, B) Minimum side clearance from combustible walls 550 mm (21B\,”) measured from the side edge of the stove top. (Fig. 12, A) Minimum distance from stove to movable combustible materials (e.g. furniture, drying clothes, etc.) 1220 mm (48”). Clearances As with any solid fuel heating stove, extremely high surface temperatures can occur, particularly in the event of uncontrolled operation, e.g. if the doors are inadvertently left open. It is crucial that sufficient clearances are allowed to any combustible surfaces, e.g. wooden mantels or lintels, and to timber framed (studded) walls even if they are faced with noncombustible board. Detailed information on fireplace and hearth construction is provided in section 2 of Document J, all installations must comply with these requirements or with the relevant National or local building standards. Clearances to timber framed (studded) walls are included below. There are no specific minimum clearances to solid noncombustible surfaces (e.g. the sides and rear of Inglenook fire openings constructed from solid masonry) other than to allow safe access to the controls of the stove. For this reason minimum side clearances of 125 mm, and a minimum rear clearance of 50 mm are recommended. 10 B A ST486a Fig. 12 Minimum clearances.

Except when starting or reviving a fire, adding fuel or when the stove doors are open, the damper should always be closed. Operation for extended periods with the bypass open could result in overfiring of the stove causing a possible safety hazard and damage to the stove. Low Heat High Heat Symbols cast into the stove indicate the correct directions for opening and closing the controls. The symbols assume that you are facing the front of the stove. Damper Handle Griddle Handle Door Handle Air Control Lever Door Handle Holder (Behind leg) Ashdoor Handle Andirons ST636 Fig. 19 The Encore controls are conveniently located and easy to operate. ST633 A Single Air Control Regulates Heat Output and Burn Time Encore controls The primary air control lever, located on the right side of the stove, controls 2/01 the amount of incoming air for starting, maintaining, and reviving a fire. More air entering the stove makes the fire burn hotter and faster, while less air prolongs the burn at a lower heat level. High and low settings appear in Figure 20. For the greatest air supply and maximum heat output (but the shortest burn time), move the lever toward the front of the stove. For a fire that will last longer with less heat, move the lever toward the rear of the stove. A Damper Directs Air Flow Within the Stove The damper handle on the left side of the stove opens and closes the damper to direct air flow within the stove. 14 ST637 Fig. 20 The handle may be positioned anywhere between the two extremes for different heat levels. The damper is open when the handle points to the back of the stove, enabling smoke to pass directly into the chimney. The damper must be open when starting or reviving a fire, and before and whenever the griddle or doors are opened. ST637 encore Air control When closing the damper, be sure to pull firmly enough to snap it into the locked position. 2/01 The damper is closed when the handle points forward. Smoke from the fire is directed through the secondary combustion system where it can be further burned for greater efficiency, before passing up the chimney. Damper Positions Open (Updraft Mode) Closed (High Efficiency Mode) ST638 Fig. 21 The damper is either open or closed. There are no intermediate positions. Two Ways to Add Fuel ST638 Encore In addition, however, the front doors open for adding an occasional log to a fire. The Encore is not approved damper control in Europe for operation with the front doors. 2/01 The Encore’s griddle lifts for convenient top-loading of logs, and is the easiest way to regularly add fuel. 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove Andirons Help Protect the Glass Handle Your stove has andirons to keep logs away from the glass panels. The andirons are essential to maintain clear fire viewing, and should be left permanently in place. Since the andirons may slightly hinder refueling through the front doors, many stove owners will prefer the convenience of top loading through the griddle. Burn Only High-Quality Wood The Encore is designed to burn natural wood only; do not burn fuels other than that for which it was designed. ST849 Fig. 22 The Encore’s hinged griddle makes it easy to topload wood. To open the front doors, insert the handle into the door latch stub and turn it clockwise. (Fig. 23) To close them, always close the left door first. Turn the handle in the right door first clockwise to the open position and swing the door closed. Finally, push on the 34 door as you turn the handle counterclockwise (down). GRIDDLEOPEN The doors will draw in slightly, and the handle should offer some resistance as you turn it to the closed position. Clockwise to OPEN Counterclockwise to CLOSE ST544 Fig. 23 To open the front doors, turn the handle clockwise. To reduce the risk of breaking the glass, avoid striking the glass or slamming the doors. When not using the door handle, store it in the holder behind the right front leg of the stove. (Fig. 19) This stove id designed to operate efficiently with the fire doors (front doors and griddle) closed. The firebox and ash doors should be kept closed at all times except when refueling or removing ashes. Infrared Reflective Glass Panels for Clear Fire Viewing ST544 The inner surfaces of the infrared reflective glass door open panels are kept at a higher temperature than the outer surface. This design, along with a11/00 preheated ‘airwash,’ makes clear fire viewing possible at most levels of operation. 30003845 You’ll enjoy the best results when burning wood that has been adequately air-dried. Avoid burning “green” wood that has not been properly seasoned, or cordwood dried more than two years. Do not burn construction materials; they often contain chemicals and metals that are harmful to the stove, chimney system and the environment. The wood should be 457-610 mm (18-20”) in length. The best hardwood fuels include oak, maple, beech, ash, and hickory that has been split, stacked, and airdried outside under cover for at least one year. If hardwood is not available, you can burn softwoods which include tamarack, yellow pine, white pine, Eastern red cedar, fir, and redwood. These too should be properly dried. The basic difference between hard and soft wood is their density. Hardwoods, because of their greater density, burn longer than softwoods and can increase the time between refuelings. Store wood under cover to keep it dry. The longer it is stored in a dry condition, the better heating and fire viewing performance you will enjoy. Even for short-term storage, however, keep wood a safe distance from the heater and keep it out of the areas around the heater used for refueling and ash removal. Use the Air Control Settings that Work Best for You No single air control setting will fit every situation. Each installation will differ depending on the quality of the fuel, the amount of heat desired, how long you wish the fire to burn, climactic conditions; outdoor air temperature and pressure may also effect draft. The control setting also depends on your particular installation’s “draft,” or the force that moves air from the stove up through the chimney. Draft is affected by such things as the length, type, and location of the chimney, local geography, nearby obstructions, and other factors. Refer to Page 19 for details on how the installation affects performance. Too much draft may cause excessive temperatures in the Encore, and could even damage the stove. On the 15 Encore® 1450CE Non-Catalytic Woodburning Stove other hand, too little draft can cause backpuffing into the room and/or the “plugging” of the chimney. How do you know if your draft is excessively high or low? Symptoms of too much draft include an uncontrollable burn or a glowing-red stove part. A sign of inadequate draft is smoke leaking into the room through the stove or chimney connector joints, low heat output and dirty glass. In some newer homes that are well-insulated and weather-tight, poor draft may result from insufficient air in the house. In such instances, an open window near the stove on the windward side of the house will help provide the fresh air needed. In some areas provisions for outside combustion air are required. Refer to section 2 of Document J which requires an outside air vent for appliances with power outputs over 5 kW. Always refer to national and local codes to determine your specific requirements. Your Encore is equipped to deliver outside air for combustion. When first using the stove, keep track of the air control settings. You will quickly find that a specific setting will give you a fixed amount of heat. It may take a week or two to determine the amount of heat and the length of burn you should expect from various settings. Most installations do not require a large amount of combustion air, especially if adequate draft is available. Do not attempt to increase the firing of your heater by altering the air control adjustment range outlined in these directions. Use the following air control settings as a starting point to help determine the best settings for your installation. Each is described as a fraction of the total distance the lever may be moved from right to left. Encore Control Settings Burn Rate Primary Air Control Low From far right to 1/3 the distance to left Medium From 1/3 to 2/3 the distance to left High From 2/3 the distance to left to far left DO NOT OPERATE THE STOVE WITH THE ASH DOOR OPEN. OPERATION WITH THE ASH DOOR OPEN CAN CAUSE AN OVERFIRING CONDITION TO OCCUR. OVERFIRING THE STOVE IS DANGEROUS AND CAN RESULT IN PROPERTY DAMAGE, INJURY OR LOSS OF LIFE. 16 Conditioning Your Stove Cast iron is extremely strong, but it can be broken with a sharp blow from a hammer or from the thermal shock of rapid and extreme temperature change. The cast plates expand and contract with changes in temperature. When you first begin using your Encore, minimize thermal stress by allowing the plates to adjust gradually during three or four initial break-in fires. Starting and Maintaining a Wood Fire Burn only solid wood in the Encore, and burn it directly on the grate. Do not elevate the fuel. Do not burn coal or other fuels. The bypass damper must be open when starting a fire or when refueling. Do not use chemicals or fluids to start the fire. Do not burn garbage. Never use flammable fluids such as gasoline, gasoline type lantern fuel, kerosene, charcoal lighter fluid, naptha, engine oil 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. During the break-in fires, do not let the stove get hotter than 260° C (500° F) as measured on an optional stove-top thermometer. Adjust the air control lever as necessary to control the fire. Some odor from the stove’s hot metal, the paint, and the cement is normal for the first few fires. NOTE: Some chimneys need to be “primed,” or warmed up, before they will draw sufficiently to start a fire. To correct this situation, roll up a couple pieces of newspaper, place them on top of the kindling and toward the back of the stove, light them, and close the doors. This will encourage smoke to rise rapidly, encouraging a good draft. ST263 Fig. 24 Start fire with newspaper and dry kindling. ST263 starting a fire 12/99 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove plenty of glowing embers to re-kindle the fire, and include some smaller pieces of wood in the new fuel load to help the stove regain its operating temperature quickly. Use this sequence as a guide to successful refueling. NOTE: Door handles can be hot. A glove has been included with your stove. We recommend using this glove whenever operating door or damper controls and especially when operating the top griddle. ST264 Fig. 25 Add larger pieces of wood as the fire begins to burn well. Once the draft is established, open the front door and light the rest of theST264 fuel from the bottom. Do not light the main bed of fuel untilfire the chimney begins drawing, good and repeat the procedure as often as necessary if the 12/99 initial attempt is unsuccessful. If your Encore has been broken-in previously using, continue to build the fire gradually. Add larger wood with a diameter of 76-102 mm (3-4”). Continue adding split logs of this size to the briskly-burning fire until there is a glowing ember bed at least 76 mm (3”) deep. A good ember bed is necessary for proper functioning of the combustion system and may take an hour or more to establish. Refuel While the Embers Are Still Hot When reloading, best results will be achieved if you first de-ash the stove by stirring the fuel bed to allow ash to fall through the grate into the ash pan. Do not break the charcoal into very small pieces or pound or compress the charcoal bed. It is important that air can circulate through the charcoal bed while the heater is in operation. Larger pieces of charcoal allow more air to circulate under the wood, resulting in the fire reviving more quickly. For best results when refueling, wear stove gloves to protect your hands, add fuel while the stove still has 1. Open the damper. 2. De-ash the stove as described above. Open the front doors and check the level of ash in the ash pan. Empty the pan if necessary and replace it in the stove. Close the front doors. 3. Open the griddle, load the wood (smaller pieces first), and close the griddle. 4. Allow the stove to regain its “thermal momentum” before closing the damper. This may take 15--20 minutes. 5. Close the damper and set the air control lever for the desired heat output. When the surface temperature reaches 230° C (450° F), adjust the air control for the amount of heat you desire. NOTE: If the charcoal bed is relatively thick {about 5176 mm (2”-3”)} deep, and if your fuel is well seasoned, it is possible to add fresh fuel (smaller pieces first), close the door and damper, and reset the primary air control for the desired heat output within five minutes. Warning: FIREPLACE STOVES EQUIPPED WITH DOORS SHOULD BE OPERATED ONLY WITH DOORS FULLY OPEN OR DOORS FULLY CLOSED. IF DOORS ARE LEFT PARTLY OPEN, GAS AND FLAME MAY BE DRAWN OUT OF THE FIREPLACE STOVE OPENING CREATING RISKS FROM BOTH FIRE AND SMOKE. Caution: The Encore will be hot while in operation. Keep children, clothing and furniture away. Contact may cause skin burns. DO NOT OVERFIRE THIS HEATER. Overfiring may cause a house fire, or can result in permanent damage to the stove and to the catalytic combustor. If any part of the Encore glows, you are overfiring.

Check the level at least once a day. Every few days, clear any ash from the outer edges of the firebox and the cavity areas of the stove. Most of the ash will fall through the grate. Slice or stir the ash with a shovel or poker so that it falls through the grate slots. • Remove the ash pan, making sure to keep it level. • To keep the cover from sliding off and to keep ash • • • Open Close ST545 Fig. 27 Turn the handle to the ash pan compartment clockwise to open and counterclockwise to close. IMPORTANT: Check the level of ash in the ash pan ST545 before reloading the stove. If the ash level is close to the top edge ashdoor of the pan, empty the pan according to this procedure: 11/00 • Open the damper. • Open the griddle or front doors, and use a shovel or • • poker to stir excess ash through the ash slots in the grate down into the ash pan. Close the griddle or doors, and unlatch the ash door. It will pivot, swinging the ash pan out of the stove. Slide the cover onto the pan, making sure it is securely closed. (Fig. 28) from falling on the floor, do not tilt the ash pan forward. If the stove is in operation, close the ash door while disposing of the ash. Properly dispose of the ash in a metal container with a tight-fitting lid. Store the container outdoors away from all combustible material. Return the ash pan to its original position in the stove, and close and latch the ash door. Do not operate the stove with the ash door open. This will result in over-firing, and could cause damage to the stove, void the warranty, or even lead to a house fire. Empty the ash pan regularly, typically every one to three days. The frequency will vary depending on how you operate your Encore: ash will accumulate faster at higher heat outputs. Remove ash frequently and place it outdoors in a metal container with a tight-fitting lid. Place the closed container of ash on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ash is disposed of by burial in soil or otherwise locally dispersed, it should be kept in the closed container until all cinders have thoroughly cooled. You can use wood ash as a garden fertilizer. CAUTION: Never use your household or shop vacuum cleaner to remove ash from the stove; always remove and dispose of the ash properly. ST566 Fig. 28 Be sure the cover is securely attached before removing the ash pan. 18 34 REMOVEASHPAN 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove Draft Management A stove is part of a system which includes the chimney, the operator, the fuel and the home. Each part of the system affects how well the stove operates. When there is a good match between all the parts, the system works well. Wood stove or insert operation depends on natural (unforced) draft. Natural draft occurs when the smoke is hotter (and therefore lighter) than the outdoor air at the top of the chimney. The larger the temperature difference, the stronger the draft. As the smoke rises from the chimney it provides suction or ‘draw’ that pulls air into the stove for combustion. A slow, lazy fire with the stove’s air inlets fully open indicates a weak draft. A brisk fire, supported only by air entering the stove through the normal inlets, indicates a good draft. The stove’s air inlets are passive; they regulate how much air can enter the stove, but depend entirely on the draft of the chimney. Depending on the features of your installation - (i.e. metal or masonry chimney installed, inside or outside the house, matched to the stove’s outlet or oversized) your system may warm up quickly or it may take a while to warm up and operate well. With an ‘airtight’ stove or insert, one which restricts the amount of air getting into the firebox, the chimney must keep the smoke warm all the way to the outdoors. Some chimneys do this better than others. Here is a list of features and their effects. Masonry Chimney Masonry is a traditional material for chimneys, but it can perform poorly when it serves an ‘airtight’ stove. Masonry is a very effective ‘heat sink’ - it absorbs a lot of heat. It can cool the smoke enough to diminish draft. The bigger the chimney, the longer it takes to warm up. It’s often very difficult to warm up an outdoor masonry chimney, especially an oversized one, and keep it warm enough to maintain an adequate draft. Metal Chimney Most factory-made metal chimneys have a layer of insulation around the inner flue. This insulation keeps the smoke warm. The insulation is less dense than masonry, so a steel chimney warms up more quickly than a masonry chimney. Metal doesn’t have the good looks of masonry, but it often performs much better. Indoor / Outdoor location Because the chimney must keep the smoke warm, it is best to locate it inside the house. The relatively warm house then surrounds the chimney keeping it warm. This also means that heat from the chimney walls will transfer to the house and not be wasted outdoors. An indoor chimney will not lose its heat to the outdoors, so 30003845 it takes less heat from the stove to heat it up and keep it warm. Flue Sizing The interior size of a chimney for an ‘airtight’ stove should match the size of the stove’s flue outlet. When a chimney serves an airtight stove, “more” is not “better”; in fact, it can be a disadvantage. Exhaust gases move more slowly through larger chimneys and can lose more heat to the chimney walls. This weakens the draft strength. If an oversized flue is also outside the house, the heat it absorbs gets transferred to the outdoor air and the flue is further cooled. It’s common for a masonry flue, especially one serving a fireplace, to be oversized for the stove. It can take quite a while to warm up such a flue, and the results can be disappointing. The best solution to an oversized flue is an insulated steel chimney liner, the same diameter as the stove or insert’s flue outlet; the liner keeps the exhaust warm, and the result is a stronger draft. An uninsulated liner is a second choice - the liner keeps the exhaust path restricted to its original size, but the air around the liner must still be heated. This makes the warm-up process take longer. Pipe & Chimney Layout Every turn the exhaust must take as it travels to the chimney top will slow it down. The ideal pipe and chimney layout is straight up from the stove, and into a vertical chimney. If you are starting from scratch, use this layout if possible. If the stovepipe must turn to enter a chimney, locate the thimble about midway between the stove top and the ceiling. This achieves several goals: it allows the exhaust gases to speed up before turning, it leaves some pipe in the room for heat transfer, and gives you long-term flexibility to install a future stove without relocating the thimble. There should be no more than 8 feet (2.4m) of singlewall stove pipe between the stove and a chimney; longer runs can cool the exhaust gases enough to cause draft and creosote problems. Use double-wall stove pipe for long runs. Single venting Each ‘airtight’ stove requires its own chimney. If an airtight stove is vented to a flue that also serves an open fireplace, it is easier for the chimney draft to pull air in through those channels than it is to pull air through the stove, and performance suffers. Imagine a vacuum cleaner with a hole in the hose to see the effect here. In some cases the other appliance can even cause a negative draft through the airtight, and result in a dangerous draft reversal. 19 Encore® 1450CE Non-Catalytic Woodburning Stove Creosote Draft Testing Creosote is a by-product of slow wood-burning. It is an organic tar that can condense in the flue if the exhaust gases cool too much. Condensed creosote is volatile, and can fuel chimney fires if it gets hot enough. All the factors that affect chimney draft also affect creosote condensation - so use installation features and operational steps that will encourage good draft and minimize creosote production. Because letting the smoke cool off and slow down is one of the keys to creosote production, it makes sense to line a chimney to match the stove’s outlet size, for safety reasons as well as performance. Consult a qualifed installer and check local and national codes for recommended chimney sizing. An easy way to test your chimney draft is to close the stove’s damper, wait a few minutes to let the airflow stabilize, then see whether you can vary the strength of the fire by swinging the air control open and closed. Results are not always instant; you may need to wait a few minutes for a change in the air control setting to have an effect on the fire. If there’s no change, then the draft isn’t strong enough yet to let you close the damper, and you’ll need to open it for a while longer and manage the fire with the air inlet until the draft strengthens. Test chimney draft with a draft gauge. Fuel Even the best stove installation will not perform well with poor fuel. The best fuel is hardwood that has airdried 12-18 months and is stored, covered from the elements. Softwoods burn well, but not as long as hardwood. ‘Green’ wood has more moisture in it; it will burn, but more of the heat from the fire is needed to drive the extra moisture off the wood. This reduces the amount of heat that reaches your home and can contribute to a creosote problem. There are moisture meters available for firewood; you can also judge your wood by its appearance and weight. If you get it green, lift a piece and get a sense of its weight; it can lose a third or more of its weight as it dries. Also look at the ends of a log; as it dries it shrinks and often cracks. The more weathered and cracked a piece is, the drier it is. Back-puffing “Back-puffing” results when the fire produces volatile gases faster than the chimney draft pulls them out of the firebox. The gases back up in the firebox until they are dense enough and hot enough to ignite. If your stove back-puffs, you should open the damper to direct more heat up the chimney to allow the smoke to rise to the flue more quickly, let more air into the firebox. Smaller loads of wood, larger pieces of wood and avoiding overly dry wood loaded into a very hot stove may help this problem. If back-puffing persists, contact your dealer or qualified chimney sweep to help diagnose the problem. 20 Negative Pressure Good draft also depends on a supply of air to the stove; a chimney can’t pull in more air than is available to it. Sluggish draft results when a house is tight enough to prevent the ready flow of air to the stove, or by competition between the stove and other equipment that removes air from the house - especially power-driven equipment like range hoods, clothes dryers, etc. If the chimney draws well with all other equipment turned off (or sealed, in the case of fireplaces and/or other stoves), then you simply need to be careful with timing the use of the other equipment. If you need to crack a nearby window or door to enable the chimney to pull well, that’s a sign that you should install an outside-air intake to bring combustion air directly to the stove. For most of our stoves, adapters are available to connect an air duct for outdoor combustion air. In many cases, local or national codes require the installation of permanently open air vents, particularly with larger appliances (i.e. above 5 kW). Refer to these codes to determine specific requirements for your installation. Conclusion Wood-burning is an art rather than a science. Once the stove and chimney system are in place, you can only vary your technique, mostly your timing, to achieve good results. If you keep track of your burning habits and relate them to their effects on the stove’s operation, you’ll be rewarded with good performance and a safe system. 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove Maintenance Below you will find important information on general care, inspection and maintenance of your Vermont Castings stove. Should it become necessary, use only replacement parts recommended by your authorized dealer. Keep Your Stove Looking New and Working Its Best Let the fire in the stove go out and allow the stove to cool completely before beginning any maintenance procedure. Care of the Cast Iron Surface An occasional dusting with a dry rag will keep the painted cast iron of your Encore looking new. The stove’s paint can be touched up as needed. First, mask the areas, such as enamelled parts, glass, or handles, around the area to be painted. Clean the area with a wire brush to remove any loose paint or dust. Remove the griddle and set it aside. Then, touch up the stove with Vermont Castings’ high temperature stove paint. Apply the paint sparingly; two light coats of paint are better than a single heavy one. Care of the Porcelain Enamel Surface Removing the Glass 1. Remove the right and left door assemblies by raising the door until the lower hinge pin clears its drilling; then, angle the door bottom slightly outward and pull down to release the upper hinge pin. Place the doors face down on a padded work surface. 2. Remove the screws that hold the retainer clips in place, and remove the clips. 3. Carefully lift the broken glass panel from the door. Installing the Glass Check the gasket around the window; it should be soft and resilient so the glass will seal properly against the door. Replace the gasket if it has hardened or if it is compressed. 1. Center the first pane of glass on the gasket. Be sure to place the glass so the infrared reflective coating is on the exterior side. Right Door Gasket Glass Panel Use a dry or slightly damp rag or soft brush to remove spills or stains. For difficult jobs that require a cleaning agent, use only a kitchen appliance cleaner or polish recommended for use on enamel surfaces. Retainer Clips (4) Cleaning the Glass Most of the carbon deposits on the glass will burn off during hot fires. However, the ash residue that accumulates on the glass surface should be removed regularly to prevent etching. To clean the glass, follow this procedure: • Be sure the glass is completely cool. • Clean the glass with water or a cleaner made especially for this purpose. Do not use abrasive cleaners. • Rinse the glass thoroughly. • Dry the glass completely. Replace Broken Glass Immediately Do not operate your stove if the glass in the doors is damaged. If you need to replace the glass, use only the high temperature ceramic glass supplied by Vermont Castings. Do not use substitutes. Be sure to specify left or right glass; the panels are not interchangeable. 30003845 ST854 Fig. 29 Exploded view of the glass assembly for the right door. 2. Secure the glass on both doors with the retainer 34a little loose. clips, but leave the screws 3. Gradually tighten allGLASSXVIEW the screws by hand a little at a time in order to apply even pressure to the glass panel. Adjust the Damper as Needed The tension on the Encore’s damper is adjustable to compensate for compression of the gasket that seals the damper to the upper fireback. To adjust the damper: 1. Remove the griddle. Loosen the lock nut at the center of the damper. 2. Turn the pressure screw approximately one half turn clockwise. 21 Encore® 1450CE Non-Catalytic Woodburning Stove 3. Tighten the lock nut. Keep the pressure screw from turning as you tighten the nut. Re-test the damper. Lock Nut Damper Pressure Adjusting Screw Replace the Stove Gaskets as Needed Your Encore uses rope-type fiberglass gaskets to make a tight seal between some parts. With use, particularly on those parts that move, gaskets can become brittle and compressed and can begin to lose their effectiveness. These will need periodic replacement. All of the gaskets are made of fiberglass. The sizes of replaceable gasket are listed below, along with their applications. ST642 Fig. 30 Adjusting the damper. Tighten the Damper Handle as Needed A handle on the left side of the stove controls the damper. The handle attaches to the damper rod with a ST642 set screw.

The Encore’s front doors, as well as its ash pan door, should close securely to prevent accidental opening and to keep air from leaking into the stove. On adequately adjusted doors, the handles should resist slightly as they are turned to the closed position and the doors themselves should be drawn slightly toward the stove. If you need to change a gasket, first obtain an appropriate replacement from your Vermont Castings’ Authorized Dealer. Over time, the gasket around the doors will compress and the latches may need adjustment. The procedure for replacing gaskets is the same regardless of the gasket location. Follow these steps: To adjust the latches on the doors, loosen the small lock nut, rotate the striker screw a half-turn, and retighten the small lock. Hold the striker screw to keep it from turning as you tighten the lock nut. Make repeated small adjustments until the setting is right. 1. Remove the existing gasket by grasping an end and pulling firmly. Wait until the fire is out and the stove has cooled. Be sure to follow the standard safety procedure for working with dusty materials: Wear safety goggles and a dust mask. 2. Use a wire brush or the tip of a screwdriver to clean the channel of any remaining cement or bits of gasket. (Fig. 32) Remove stubborn deposits of cement with a cold chisel if necessary.

Adjust the Door If Necessary The stove’s door(s) may need adjustment after you have regasketed it. Initially, it may require loosening to accommodate the new gasket; after a few weeks, it may need tightening to compensate for compression of the new gasket. The directions for adjusting the doors are on Page 22. All Gasketed Construction Other gaskets form seals between non-moving parts, but these are not subject to the same wear and deterioration as gaskets on moving parts. It is unlikely that you will ever need to replace these gaskets unless the involved parts are disassembled and then put back together. If this is the case, the job should be done only by a qualified service technician. 30003845 5/16” diameter gasket seals the following parts: • The flue collar to the stove back • The lower fireback to the sides • All connections between the major stove plates The Chimney System Creosote Your Encore is designed to reduce creosote build-up significantly. However, regular chimney inspection and maintenance must still be performed. For safety, good stove performance, and to protect your chimney and chimney connector, inspect your chimney and chimney connector on a regular schedule. Clean the system if necessary. Failure to keep the chimney and connector system clean can result in a serious chimney fire. When wood is burned slowly, it produces tar, organic vapors and moisture that combine 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 hot fire within the flue system that can damage the chimney and overheat adjacent combustible material. If a significant layer of creosote has accumulated —3 mm (1/8”) or more — it should be removed to reduce the risk of a chimney fire. To reduce the amount of creosote that may form, remember to provide adequate air for combustion and to strive for small, intense fires rather than large, smoldering ones. You can never be too safe. Contact your local fire authority for information on what to do in the event of a chimney fire, and have a clearly understood plan on how to handle one. You should inspect the system every two weeks during the heating season as part of a regular maintenance schedule. To inspect the chimney, let the stove cool completely. Then, using a strong light, sight up through the flue collar into the chimney flue. If it is not possible to inspect the flue system in this fashion, the stove must be disconnected to provide better viewing access. Clean the chimney using a brush the same size and shape as the flue liner. Flexible fiberglass rods are used to run the brush up and down the liner, causing any deposits to fall to the bottom of the chimney where they can be removed through the clean-out door. Clean the chimney connector by disconnecting the sections, taking them outside, and removing any deposits with a stiff wire brush. Reinstall the connector sections after cleaning, being sure to secure the joints between individual sections with sheet metal screws. If you cannot inspect or clean the chimney yourself, contact your local Vermont Castings’ Dealer or a professional chimney sweep. 23 Encore® 1450CE Non-Catalytic Woodburning Stove Maintenance Schedule The Chimney Connector The stove and chimney system should be inspected and maintained by a qualified engineer and include the following: TWO WEEKS: • Inspect the chimney connector and chimney. Clean if necessary. TWO MONTHS: • Inspect the chimney and chimney connector. Pay particular attention to the horizontal runs of chimney connector, and the elbows. Clean the system if necessary. Annual Spring Cleaning: • Disassemble the chimney connector and take it outdoors for inspection and cleaning. Replace weak sections of connector. • Inspect the chimney for signs of deterioration. Repairs to a masonry chimney should be made by a professional mason. Replace damaged sections of prefabricated chimney. Your local Vermont Castings dealer or a chimney sweep can help determine when replacement is necessary. • Thoroughly clean the chimney. The Stove DAILY: • Clear any ash build-up from around the air holes and combustion flow path in the lower fireback. • Ashes should be removed before they reach the top of the ash pan. Check accumulation at least once a day. • Keep the area around the stove clear of any combustible materials such as wood, furniture or clothing. TWO MONTHS: • Check door handle to be sure it is working properly. Gasketing becomes compressed after a period of time. Adjust handle tightness if necessary. • Check leg bolts and heat shield screws; tighten if necessary. Annual Spring Cleaning: • Check gasketing for wear, and replace if necessary. • Remove ashes from the ash pan and replace with a moisture absorbing material (such as kitty litter) to keep the interior of the stove dry. • Clean the dust from the inner sides of bottom, rear or pipe heat shields if your stove is equipped with them. Clean surfaces are better heat reflectors than dirty surfaces. • Touch up the black paint. • Inspect for and remove ash build-up behind the combustion package. This should be done in conjunction with annual cleaning of the chimney connector since this inspection is most conveniently done through the flue collar opening. Inspect the passages to either side of the combustion package (a mirror will be helpful) and vacuum away ash using a flexible vacuum hose inserted into each passage. Care should be taken not to damage the white fibrous material in this rear chamber. (Fig. 34) Inspect and Vacuum Both Rear Corners Ash Build-up ST856 Fig. 34 Inspect and clean out ash accumulation on either side of the non-catalytic combustion system. 34 CLEANASH 24 30003845 Encore® 1450CE Non-Catalytic Woodburning Stove 69 78 47 7 12 6 71 13 8 72 9 11 1 2 52 42 37 10 61 32 68 60 56 3 59 67 22 73 62 55 56 20 32 66 52 51 12 4 80 21 51 5 74 64 19 54 45 48 49 50 23 53 58 25 27 42 24 77 28 18 17 57 41 14 16 46 75 27 65 53 26 44 38 34 39 15 42 35 28 36 77 76 62 70 32 43 31 40 29 30 33 MHSC reserves the right to make changes in design, materials, specifications, prices and discontinue colors and products at any time, without notice.

This coverage includes the components of the EverBurn System: “shoe, fountain, and fireback. Coverage is provided only to the original purchaser. Limited 3 Year Warranty All cast iron parts are warranted for a period of three years against breakage, cracking or burn-through. Limited 1 Year Warranty The following part of the woodburning stove are warranted to be free of defects in material and workmanship for a period of one year from the date you receive it: The handles, glass door panels, door gasketing and porcelain finish. Any of these items found to be defective will be repaired or replaced at no charge, upon the return of the part with postage prepaid to a Vermont Castings Authorized Dealer. Any parts repaired or replaced during the limited warranty period will be warranted under the terms of the limited warranty for a period not to exceed the remaining term of the original limited warranty or six (6) months, whichever is longer. Exclusions & Limitations 1. This warranty is non-transferable. 2. This warranty does not cover misuse of the stove. Misuse includes overfiring, which will result if the stove is used in such a manner as to cause one or more of the plates to glow red. Overfiring can be identified later by warped plates and areas where the paint pigments has burned off. Overfiring in enamel stoves is identified by bubbling, cracking, chipping and discoloration of the porcelain enamel finish. MHSC offers no warranty on chipping of enamel surfaces. Inspect your woodburning stove prior to accepting it for any damage to the enamel. 3. This warranty does not cover misuse of the stove as described in the Owners Guide, nor does it cover a stove which has been modified unless authorized by a MHSC representative in writing. This warranty does not cover damage to the stove caused by burning salt saturated wood, chemically treated wood, or any fuel not recommended in the Owners Guide. 4. This warranty does not cover a stove repaired by someone other than a Vermont Castings Authorized Dealer. 5. Damage to the unit while in transit is not covered by this warranty but is subject to a claim against the common carrier. Contact Vermont Castings Authorized Dealer from whom you purchased your stove or MHSC if the purchase was direct. (Do not operate the stove as this may negate the ability to process the claim with the carrier). 6. Claims are not valid where the installation does not conform to local building and fire codes or, in their absence, to the recommendations in our Owners Guide. 7. The salt air environment of coastal areas, or a highhumidity environment, can be corrosive to the porcelain enamel finish. These conditions can cause rusting of the cast iron beneath the porcelain enamel finish, which will cause the porcelain enamel finish to flake off. This warranty does not cover damage caused by a salt air or high-humidity environment. 8. MHSC shall have no obligation to enhance or update any unit once manufactured. IN NO EVENT SHALL MHSC BE LIABLE FOR INCIDENTAL AND CONSEQUENTIAL DAMAGES. ALL IMPLIED WARRANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS, ARE LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY. THIS WARRANTY SUPERCEDES ALL OTHER ORAL OR WRITTEN WARRANTIES. Some states do not allow the exclusion or limitations of incidental and consequential damages or limitations on how long an implied warranty lasts, so the above limitations may not apply to you. This warranty gives you specific rights and you may have other rights, which vary from state to state. How to Obtain Service If a defect is noted within the warranty period, the customer should contact a Vermont Castings Authorized Dealer or MHSC if the purchase was direct with the following information: 1. Name, address, and telephone number of the purchaser 2. Date of Purchase. 3. Serial number from the label on the back 4. Nature of the defect or damage. 5.
