4 Installation SAFETY NOTICE: IF YOUR DUTCHWEST CONVECTION HEATER IS NOT PROPERLY INSTALLED, OPERATED AND MAINTAINED, A HOUSE FIRE MAY RESULT. FOR SAFETY, FOLLOW ALL INSTALLATION, OPERATION AND MAINTENANCE DIRECTIONS. CONTACT LO- CAL BUILDING OFFICIALS ABOUT RESTRICTIONS AND INSTALLATION INSPECTION REQUIREMENTS IN YOUR AREA. Before you begin the installation, review your plans to confirm that: Your stove and chimney connector will be far enough from combustible material to meet all clearance requirements. The floor protector is large enough and is constructed properly to meet all requirements. You have obtained all necessary permits from local authorities. Your local building official is the final authority for approving your installation as safe and for determining that it meets local and state codes. Clearance and installation information is printed on the metal label attached to the rear of the stove. Local authorities generally will accept the label as evidence that, when the stove is installed according to the information on the label and in this manual, the installation meets codes and can be approved. Codes vary in different areas, however. 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. Chimney Types Your Dutchwest Convection Heater must be connected to 1) a chimney complying with the requirements for Type HT chimneys in the standard for Chimneys, Factory-Built, Residential Type and Building Heating Appliance, UL 103, or 2) a code-approved masonry chimney with a flue liner. Whatever kind you use, the chimney and chimney connector must be in good condition and kept clean. Masonry Chimneys If you use an existing masonry chimney, it must be inspected to ensure safe condition before the stove is installed. Your local professional chimney sweep, building inspector, or fire department official will be able either to make the inspection or to direct you to someone who can. An inspection of the chimney must confirm that it has a lining. Do not use an unlined chimney. The chimney should also be examined for cracks, loose mortar, other signs of 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. Tile Lined Masonry Chimney Prefabricated Double-Wall Insulated Chimney Fig. 2 If in sound condition and approved for use, either a masonry or a prefabricated chimney may be used. ST

5 Prefabricated Chimneys A prefabricated metal chimney must be one tested and listed for use with solid-fuel burning appliances. A horizontal connector run should be inclined 1/4 per foot (20 mm per meter) from the stove toward the chimney. The recommended maximum length of a horizontal run is 3 feet (1 m) and the total length of chimney connector should be no longer than 8 feet (2.5 m). Chimney Height For proper draft and good performance, the chimney should extend at least 16 (5 m) above the flue collar of the stove. The chimney must also extend at least 3 (914 mm) above the highest point where it passes through a roof, and at least 2 (610 mm) higher than any portion of a building within 10 (3 m). (Fig. 2) DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. 0 To 10 2 Min. 3 Min. Reference Point Fig. 3 The 2/3/10 rule for chimneys. 0 To 10 2 Min. 3 Min. Chimney Size AC246 The Model 2477 heater should be vented into a masonry chimney with a square flue with nominal flue size of 8 x 8 (203 x 203 mm), or a round flue with nominal flue size of 6 (152 mm). Chimney liners larger than 8 x 12 (203 x 305 mm) may promote rapid cooling of smoke and reduction in draft, especially if they 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 the stove are available through your local dealer. Guidelines for Installing the Chimney Connector The chimney connector is the single-wall pipe, or listed and approved double-wall pipe that connects the stove to the chimney. The chimney itself is a masonry or prefabricated structure that encloses the flue. Chimney connectors are used only to make the connection from the stove to the chimney. Do not pass the chimney connector through a combustible wall, floor, or ceiling, through an attic or roof space, or through a closet or similar concealed space. If passage through a combustible wall is unavoidable, follow the recommendations in the following section on Wall Pass- Throughs. Keep the passage as short and direct as possible, with no more than two 90 degree turns. Two Types of Connector You may use either a single-wall steel connector of the size and gauge described below, or a listed and approved double-wall connector. Single-Wall Connector The single-wall chimney connector should be made of 24 gauge or heavier steel, and must have a minimum internal diameter of 6 (150 mm) for model Install single-wall chimney connector not less than 18 (450 mm) from the ceiling. In cathedral ceiling installations, extend the prefabricated chimney downward to within 8 feet (2.5 meters) of the stove. The entire chimney connector should be exposed and accessible for inspection and cleaning. Do not use galvanized chimney connector; it cannot withstand the high temperatures that can be reached by smoke and exhaust gases and it may release toxic fumes under high heat. Chimney Elbow Slip Pipe Standard Connector Flue Collar Flue Liner Flue Thimble Floor Protector ST418 Fig. 4 Sections of a steel chimney connector of at least 24 gauge thickness are fastened together with screws to connect the stove to the chimney

6 Double-Wall Connector Information on assembling and installing double-wall connectors is provided by the manufacturer of the double-wall pipe. Follow the manufacturer s installation instructions exactly. Most manufacturers of prefabricated double-wall insulated chimneys also offer double-wall connector pipes. Using a chimney and connector pipe from the same manufacturer helps simplify the assembly and installation. NOTE: For installations using double-wall connectors, minimum clearances must conform to listed clearances in the Stove and Chimney Connector Clearance Charts on Page 12 and 13 of this manual. Assembling Single-Wall Chimney Connector SAFETY NOTE: Always wear gloves and safety goggles when drilling, cutting or joining sections of chimney connector. For double-wall connectors, follow the manufacturer s instructions exactly. For single-wall connectors, follow the instructions below. 1. Insert the crimped end of the first section into the stove s flue collar, and keep each crimped end pointing toward the stove (Fig.5). Using the holes in the flue collar as guides, drill 1/8" (3 mm) 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. Toward Stove 2. Secure each joint between sections of chimney connector, including telescoping joints, with at least three sheet metal screws. 3. Secure the chimney connector to the chimney. Instructions for various installations follow below. 4. Confirm that the installed stove and chimney connector are correct distances from nearby combustible material. See the clearance charts on pages 12 and 13. NOTE: Special slip pipes and thimble sleeves that form telescoping joints between sections of chimney connector are available to simplify installations. They can eliminate the need to cut individual connector sections. Consult your local dealer about these special pieces. Securing the 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 adaptors are available from your local dealer to make the connection between the prefabricated chimney and the chimney connector. (Fig. 6) The top of such adaptors attach directly to the chimney or to the chimney s ceiling support package, while the bottom of the adaptor is screwed to the chimney connector. These adaptors 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. Any soot or creosote falling from the inner walls of the chimney will stay inside the chimney connector. Prefab (Insulated) Chimney Flue Gas Direction ST242 Fig. 5 Crimped sections always point toward the stove so that any liquid condensation will not leak out.

7 Securing the Connector to a Masonry Chimney The Dutchwest Convection heater may be connected to either a freestanding masonry chimney or a masonry fireplace chimney. Freestanding Installations If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations in the wall pass-through section that follows. 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 securely cemented in place. (Fig. 7) Most chimney breeches incorporate thimbles, but check to be sure the fit is snug and the joint between thimble and chimney wall firmly cemented. A special piece called the thimble sleeve, slightly smaller in diameter than the standard connector and most thimbles, will ease the removal of the chimney connector system for inspection and cleaning. Thimble sleeves should be available from your local dealer. To install a thimble sleeve, slide it into the breech until it is flush with the inner flue wall. Don t extend it into the actual flue passage, as that could interfere with the draft. The thimble sleeve should protrude 1-2" (25-50 mm) into the room. 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. Fireplace Installations - Above the Fireplace In this installation, the chimney connector rises from the stove, turns ninety degrees, and goes back into the fireplace chimney. The liner of the fireplace chimney should extend at least to the point at which the chimney connector enters the chimney. Follow all the guidelines for installing a chimney connector into a freestanding masonry chimney, and pay special attention to these additional points: Check the stove and chimney connector clearances to combustible mantel or trim materials. Use the necessary combination of mantel, trim, and connector heat shields to provide the required clearances. (Fig. 8) Double-check connector clearance from the ceiling. The fireplace damper must be closed and sealed to prevent room air from being drawn up the flue, reducing the draft. However, it must be possible to re-open the damper to inspect or clean the chimney.

Special Fireplace Adapter Kits to simplify fireplace installations are available from your local dealer

8 Fireplace Installations - Through the Fireplace The Convection heater may be installed either without legs* as a fireplace insert, or with standard legs attached - depending on the safety regulations that apply to your situation, the height of the fireplace opening and your own preference. For either situation, the chimney connector/positive connection kit extends back from the stove, enters the fireplace cavity, and turns upward. It then passes through the fireplace damper opening and smoke chamber and connects to the chimney flue. In such installations, a positive connection must be made to the chimney flue with a special kit available from your local dealer. Also, special clearance and floor protection provisions must be observed. These provisions are discussed in the Clearance and Floor Protection sections respectively. Wall Pass-Throughs Whenever possible, design your installation so the connector does not pass through a combustible wall. If you must use a wall pass-through in your installation, check with your building inspector before you begin and construct it in accordance with local building codes. Also check with the chimney connector manufacturer for any specific requirements. Accessories are available for use as wall pass-throughs. If using one of these, make sure it has been tested and listed for use as a wall pass-through. All combustible material in the wall is cut away a sufficient distance from the single-wall connector to provide the required 12" (305 mm) clearance for the connector. Any material used to close up the opening must be noncombustible. The following wall pass-through methods may be approved in your area: Use a section of listed factory-built chimney with a nine-inch clearance to combustibles. Place a chimney connector pipe inside a ventilated thimble, which is then separated from combustibles by 6 (152 mm) of fiberglass insulating material. If the stove is installed without legs, we recommend the use of noncombustible tiles or pavers as shims to allow air flow into the convection air inlets under the stove. Make sure not to block air slots instove bottom with shims or remove fan cover. Place a chimney connector pipe inside a section of listed solid-insulated, factory-built chimney, with an inside diameter 2" (51 mm) larger than the chimney connector and having 1" (25 mm) or more of insulation and maintaining a minimum 2 inch air space between the outer wall of the chimney and combustibles. Chimney Connector 12 (305mm) 12 (305mm) Fig. 10 Wall pass-through enclosed with noncombustible materials. 18 (450mm) Empty Space All Around the Chimney Connector Fig. 11 Hollow wall pass-through. ST420 Sheet Metal Cover (One side only) ST421 DO NOT CONNECT THE HEATER TO ANY AIR DISTRIBUTION DUCT OR SYSTEM In Canada: The Canadian Standards Association has established different guidelines. Figure 11 shows one method, in which all combustible material in the wall is cut away to provide the required 18" (450 mm) clearance 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 non-combustible spacers at least 1" (25 mm) clear of the wall. Your Dutchwest dealer or your local building inspector can provide details of other approved methods of passing a chimney connector through a combustible wall. In Canada, this type of installation must conform to CAN/CSA-B365, Installation Code for Solid Fuel Burning Appliances and Equipment

9 NOTE: Do not vent your Dutchwest stove into a factorybuilt (zero-clearance) fireplace. These appliances and their chimneys are specifically designed as a unit for use as fireplaces. It may void the listing or be hazardous to adapt them for any other use. B B C Floor Protection A tremendous amount of heat radiates from the bottom plate of your Dutchwest stove. The floor area directly under and around the stove will require protection from radiant heat as well as from stray sparks or embers that may escape the firebox. Heat protection is provided by the Vermont Castings Group Bottom Heat Shield. Spark, ember and thermal protection must be provided by a floor protector constructed with noncombustible material as specified. In the US and Canada most installations will require that the bottom heat shield must be attached. Only when the stove is placed on a completely noncombustible surface such as unpainted concrete over earth may it be used without the heat shield. Even when the bottom heat shield is installed, you must provide special protection to the floor beneath. For installation with the heat shield attached, use an approved 7/8" (22mm) noncombustible hearth pad with K = 0.84 BTU/ in. ft 2 hr. F or an equivalent material with an R-value of at least (Refer to How to Determine if Alternate Floor Protection Materials are Acceptable section) The floor protector may be covered with a decorative noncombustible material if desired. Do not obstruct the space under the heater. Protection requirements vary somewhat between the United States and Canada as follows: U.S. Installations: The floor protector is required under the stove and must extend at least 16 from the front and left (loading door) side of the stove, and at least 6 from the right side and rear. (Fig. 12) In Canada: a noncombustible floor protector is required under the heater also. The floor protector must extend 18 (457mm) from the front and left (loading door) side of the stove, and at least 8 (203mm) from the right side and rear. (Fig. 12) Due to the side loading door, floor protector requirements call for more protection on the left side than on the right. If you wish a more balanced look, increase the other side of the hearth as well. Do not reduce side protection under any circumstances.

10 How to Determine if Alternate Floor Protection Materials are Acceptable All floor protection must be noncombustible (i.e. metals, brick, stone, mineral fiber boards, etc.). Any organic materials (i.e. plastics, wood paper products, etc.) are combustible and must not be used. The floor protection specified includes some form of thermal designation such as R-value (thermal resistance) or k-factor (thermal conductivity). Procedure: 1. Convert specifications to R-value: i. R-value given - no conversion needed. ii. k-factor is given with a required thickness (T) in inches: R = 1 x T k iii. K-factor is given with a required thickness (T) in inches: R = 1 x T K x 12 iv. r-factor is given with a required thickness (T) in inches: R = r x T 2. Determine the R-value of the proposed alternate floor protector: i. Use the formula in Step 1 to convert values not expressed as R. ii. For multiple layers, add R-values of each layer to determine overall R-value. 3. If the overall R-value of the system is greater than the R-value of the specified floor protector, the alternate is acceptable. EXAMPLE: The specified floor protector should be 7/8-inch thick material with k-factor of The proposed alternate is 4" brick with an r-factor of 0.2 over 1/8" mineral board with a k-factor of 0.29 Step a: Use formula above to convert specification to R- value: 1 1 R = x T = x = 1.04 k 0.84 Step b: Calculate R of proposed system. 4" brick of r = 0.2, therefore: R brick = 0.2 x 4 = 0.8 1/8" mineral board of k = 0.29, therefore R mineralboard = 1 x = R total = R brick + R mineralboard = = Step c: Compare proposed system Rtotal of to specified R of Since proposed system Rtotal is greater than required, the system is acceptable. Definitions R = (ft2 )(hr)( F) Btu k = (Btu)(in) = K x 12 (ft 2 )(hr)( F) K = (Btu)(ft) (ft 2 )(hr)( F) r = (ft2 )(hr)( F) (Btu)(in) 1 k Fireplace Installations The Dutchwest Model 2477 has a reversible flue collar to allow for either top exit or rear exit installations. You may install your Dutchwest Model 2477 in an existing fireplace as a fireplace insert with no legs, or with the standard legs attached. To install the heater without legs as a fireplace insert, the floor must be completely noncombustible, such as an unpainted concrete floor over earth. Many fireplaces do not satisfy the "completely noncombustible" requirement because the brick or concrete hearth in front of the fireplace opening usually is supported by heavy wooden framing as in Figure 13. Because heat passes readily through brick or concrete, it can easily pass through to the wood. As a result, such fireplace hearths are considered a combustible floor. You may not install a heater on a combustible hearth without legs. Standard leg installations must include the bottom heat shield. The floor protector must also meet standard requirements for freestanding installations. Floor Protection for Fireplace Installations with Standard Legs Fireplace installations with the standard legs and the bottom heat shield must have a floor protector of the same construction as that specified for freestanding installations: an approved 7/8" (22mm) noncombustible hearth pad with K = 0.84 BTU/in ft 2 hr. F or equivalent material with an R-value of at least 1.04 (Refer to "How to Determine if Alternate Floor Protection Materials are Acceptable" section) The floor protector must extend at least 16" (406 mm) [18" / 457 mm in Canada] from the front of the stove and from the left (loading door) side, and at least 6" (152 mm) [8" (203 mm) in Canada] from the right side and rear. It must also provide protection beneath any horizontal runs of the chimney connector, including 2" to either side. Many raised hearths will extend less than the required distance from the front of the heater when it is installed. In such cases, sufficient floor protection, as described above, must be added to extend the hearth 16" (406 mm) [18" (457 mm) in Canada]. Hearth rugs do not satisfy the requirements for floor protection. Fireplace insert installations also have specific clearance requirements to the side walls, side decorative trim, and fireplace mantel. This information is found in "Fireplace Installation Clearances" in this section. REMINDER- FIREPLACE INSERT INSTALLATIONS WITHOUT LEGS ARE PERMISSIBLE ONLY IF THE HEARTH IS COMPLETELY NONCOMBUSTIBLE, SUCH AS UNPAINTED CONCRETE OVER EARTH

11 Clearances Keep the Stove a Safe Distance From Surrounding Materials Both a stove and its chimney connector radiate heat in all directions when operating. A safe installation requires that adequate clearance be maintained between the stove and nearby combustible materials to ensure that such materials do not overheat. Clearance is the distance between either your stove or chimney connector, and nearby walls, floors, the ceiling, and any other fixed combustible surface. Keep furnishings and other combustible materials away from the stove as well. In general, a distance of 48" (1220 mm) 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. Safe Ways to Reduce Clearances Your stove has specific clearance requirements that have been established through careful research and testing to UL and ULC standards. Clearance requirements have been established to meet every installation possibility, and they involve the combination of basic variables: When the stove has no listed heat shield When the stove has a listed heat shield When the wall has no heat shield When the wall has a heat shield When the stove has a double-wall chimney connector When the stove has a single-wall connector with heat shields, or without heat shields In general, the greatest clearance is required when you locate a stove with no heat shield near a wall with no heat shield. The least clearance is required when both the stove and the wall have heat shields. Reducing a stove clearance may require a listed heat shield on the chimney connector as well, or a double-wall connector. Clearances may be reduced only by means approved by the regulatory authority and in accordance with the clearances listed in this manual. The charts and sample installations that follow list all the clearances required for the various installation configurations of Dutchwest Convection Heaters. ST809 Fig. 14 Extra floor protection may be required for the fireplace hearth, even if your stove is installed with the legs and the bottom heat shield. Fireplace Installation Clearances A fireplace installation requires special clearance between the: Side of the stove and the right and left walls Side of the stove and the decorative side trim on the fireplace face Top of the stove and the mantel In addition, both Fireplace Adaptor and Fireplace Insert installations have special floor protection requirements that are addressed in the section on Floor Protection.

12 Alcove Installations Because of their restricted air flow and heat retention characteristics, specific construction requirements and special clearances apply to installations into alcoves. No stove or chimney connector heat shields are used in alcove installations. ALCOVE INSTALLATION OF THE DUTCHWEST MODEL #2477 IS PERMITTED IN BOTH THE US AND CANADA.

13 Designing a Safe Installation The section that follows contains charts with the information that you ll need to make your installation safe. Included are a chart to tell you exactly where to cut the hole in the ceiling so that the stove will meet clearance requirements, a chart that gives stove clearances for all installations, and a chart to illustrate the required sizes of wall shields for various installations. Refer to these charts as you plan the installation and do not compromise on any of the dimensions listed. Clearance Chart Reference Diagrams Refer to the diagrams below when using the Stove and Chimney Connector Clearance Chart that follows. For example, the letter A gives the minimum side clearance for installations in which the stove is not equipped with any heat shield and the wall beside the stove is not protected. D gives the minimum side clearance when the stove does not have any heat shield, but the wall is protected. Measure clearance distances from the top plate of the stove or chimney connector to the wall, not the wall protector.

Smoke and CO Detectors The use of smoke and carbon monoxide (CO) detectors throughout the home is strongly advised, even if not required by building codes or insurance regulations. It is a good idea to install a smoke detector in the living areas and each bedroom. Follow the smoke/co detector manufacture's placement and installation instructions and maintain regularly. You may not, however, wish to install a detector in the immediate vicinity of the stove. Depending on the sensitivity of the unit, the alarm can be set off while you are tending the fire or emptying the ashes. If you install a detector in the same room, locate it as far away from the stove as possible. Safety Tips Conveniently locate a "Class A" fire extinguisher to contend with small fires. Be sure the fire extinguisher works and is clearly visible. All occupants of the house should know where it is, and how it operates. Have heavy stove gloves available near the stove. Have special safety accessories (e.g., Child Guard Screen) available for use if small children will be in the home. In the event of a stove pipe or chimney fire. Evacuate the house immediately Notify the fire department If the fire isn't too threatening, closing down the stove tight, (damper, primary air, all doors) will help to smother the fire. Inspect your stove, stove pipe and chimney for any damage caused by the fire and correct any damage before using your stove again

19 Operation Heater Controls and Features Air Control The Dutchwest Convection Heater Model 2477 has a control that regulates the amount of air drawn into the stove. Generally, more air entering the stove allows the fire to burn hotter and faster, while less air decreases heat output and prolongs the overall burn time. The Air Control Lever is located at the lower front edge of the left side (looking from the front of the stove). (Fig. 28) The lever operates two internal shutters. Opening the inlet shutters provides air for primary combustion. Primary Air Control Lever ST811 Fig. 29 Turn primary air control lever clockwise to open. Damper Side Loading Door Primary Air Control Lever Fig. 28 The heater controls. Front Loading Door ST810 Fig. 30 Turn primary air control lever counterclockwise to close. ST812 To open the shutters, turn the lever clockwise. The shutters are all the way open when the lever points toward the rear at a 9:00 position. (Fig. 29) To close the shutters, turn the lever counterclockwise. The shutters are fully closed when the lever points straight down. (Fig. 30) WARNING This wood heater has a manufactured-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

20 Damper Function The Damper is operated by moving the handle on the upper left side of the stove. (Fig. 31) It has two positions: OPEN, to start the fire and load fuel, and CLOSED, for greatest efficiency and heat. When the damper is closed, exhaust gases travel through a secondary combustion chamber at the rear of the stove before flowing into the chimney. Use the door insert handle to rotate the damper handle. Turn it counterclockwise to open the damper and clockwise to close it. You will feel resistance as the damper mechanism engages into the open (counterclockwise) position. The stove damper must be open when you start a fire, load fuel, or before you open either door for any reason. Load Doors A Side Loading Door allows the easiest loading of wood logs. The Front Door opens for adding an occasional log to the fire. Always be sure to open the stove damper before opening either door. Open Door Insert Handle Closed Successful Wood Burning Woodburning is often said to be more of an art than a science. You ll easily master the art if you start by using good, dry fuel and by understanding how the stove s air supply system operates. Burn Only High-Quality Fuel Your heater is designed to burn natural wood only. Do not burn other fuels. Never burn pressure-treated wood, painted or stained wood, or glossy newsprint. High efficiencies and low emissions are only possible when burning air-dried, seasoned woods. Avoid burning green wood that has not been properly seasoned. The best hardwood fuels include oak, maple, beech, ash, and hickory that has been split, stacked, and air-dried outside under cover for at least one year. If hardwood is not available, tamarack, yellow pine, white pine, Eastern red cedar, fir, and redwood are softwoods that are commonly burned. They too should be properly dried. The length of the wood should be the same as that specified for your particular stove. Avoid using wood that has been dried more than two years. Often gray in color, this wood burns very quickly, resulting in short burn time and diminished stove performance. If you must burn it, mix it in with greener wood to slow the burn. Store your firewood under cover to keep it dry. Even for short-term storage, keep wood outside of the heater s installation clearances and outside of the space around the heater required for refueling and ash removal.

21 Use the Air Control Settings that Work Best for You No single control setting will fit every situation. Each installation will differ depending on the quality of the fuel, the amount of heat desired, and how long you wish the fire to burn. Control settings also depend 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 height, type, and location of the chimney, local geography, nearby obstructions, and other factors. Too much draft may cause excessive temperatures in the stove. On the other hand, too little draft can cause backpuffing into the room and/or insufficient heat. How do you know if your draft is excessively high or low? Symptoms of too much draft include an uncontrollable burn or a part of the stove or chimney connector glowing-red. Inadequate draft may is indicated by smoke leaking into the room through the stove or chimney connector joints. When first using the stove, keep a record of the results you achieve from different control settings. You will find that specific settings 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 control settings. Notice that changes in the weather have a strong effect on chimney draft. Higher outdoor temperatures and lower air pressure both weaken draft; lower temperatures and higher air pressure encourage a stronger draft. An exception to this is in installations with outdoor chimneys; since these lose heat to the outdoors, it takes longer to warm them up initially, and it takes more heat to keep them warm, especially when temperatures are very low outdoors. Most installations do not require a large amount of combustion air, especially if adequate draft is available. Do not attempt to increase the firing rate of your heater by altering the air control adjustment range outlined in these directions. In some newer homes that are well insulated and weathertight, 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 (side against which the wind is blowing) will provide the fresh air needed. Another solution is to equip the stove with an Outside Air Kit, available from your local dealer. Use the air control settings indicated in Figure 32 as a starting point to help determine the best settings for your installation. High Medium Low Closed ST817 Fig. 32 Position the primary air control lever for different burn rates. DO NOT OPERATE THE STOVE WITH THE ASH DOOR OPEN. OPERATION WITH THE ASH DOOR OPEN CAN CAUSE AN Over-firing CONDITION TO OCCUR. OVER- FIRING THE STOVE IS DANGEROUS AND CAN RESULT IN PROPERTY DAMAGE, INJURY, OR LOSS OF LIFE. How to Build and Maintain a Wood Fire Loading Wood You can load wood into your Dutchwest Convection Heater through either the front or side doors. Front loading is useful for kindling a new fire and adding an occasional log; however, we recommend side-loading as most convenient when adding several logs at a time. Always be certain that the stove damper is open before opening either door. WARNING: OPERATE YOUR DUTCHWEST CON- VECTION HEATER ONLY WITH THE DOORS FULLY CLOSED EXCEPT WHEN REFUELING. THIS STOVE IS HOT WHILE IN OPERATION! KEEP CHILDREN, CLOTHING, AND FURNITURE AWAY. CON- TACT MAY CAUSE SKIN BURNS. Break-in Fires If your stove is new or has new cast iron replacement parts, season the new cast iron with a few break-in fires. Follow Steps 1-3 below. Then let the fire burn out. Do not close the damper. Maintain a small but not smoky fire by adjusting the air control. After the break-in fires, continue with Step 4. The stove s paint and cement will emit a slight odor as these materials cure during the first few fires. You may wish to provide extra ventilation near the stove by partially opening a door or window until the odor disappears
