Encore ® Multi-Fuel Heateron Page 17 to see how the size, type, and location ofyour chimney will affect your stove operation. Whenthermometer readings drop below 175° C (350° F) it’stime to adjust the air control for a higher burn rate or toreload the stove. A temperature reading over 385° C(750° F) is a sign to cut back on the air supply to slowthe burn rate.Use the following temperature ranges as a guide tooperation:• Readings in the 175°-260° C (350-500° F) rangeindicate low to medium heat output.• 260°-315° C (500-600° F) readings indicate mediumheat output.• Readings of 315°-400° C (600-750° F) indicate highheat output. Operating your Encore continuously atgriddle temperatures of 385° C (750° F) or highermay damage the cast iron or enamel finish.14Use the Air Control Settingsthat Work Best for YouNo single air control setting will fit every situation. Eachinstallation will differ depending on the quality of thefuel, the amount of heat desired, and how long you wishthe fire to burn; outdoor air temperature and pressurealso affect draft.The control setting also depends on your particularinstallation’s “draft,” or the force that moves air from thestove up through the chimney. Draft is affected by suchthings as the length, type, and location of the chimney,local geography, nearby obstructions, and other factors.Refer to Page 23 for details on how the installation affectsperformance.Too much draft may cause excessive temperatures inthe Encore, and could even damage the combustor.On the other hand, too little draft can cause backpuffinginto the room and/or the “plugging” of the chimney orcombustor.How do you know if your draft is excessively high orlow? Symptoms of too much draft include an uncontrollableburn or a glowing-red stove part. A sign of inadequatedraft is smoke leaking into the room through thestove or chimney connector joints, low heat, and dirtyglass.In some newer homes that are well-insulated andweather-tight, poor draft may result from insufficient airin the house. In such instances, an open window nearthe stove on the windward side of the house will providethe fresh air needed.In some areas provisions for outside combustion airare required. Refer to section 2 of Document J whichrequires an outside air vent for appliances with poweroutputs over 5 kW. Always refer to national and localcodes to determine your specific requirements.Your Encore will accept a duct to deliver outside air forcombustion.When first using the stove, keep track of the air controlsettings. You will quickly find that a specific setting willgive you a fixed amount of heat. It may take a week ortwo to determine the amount of heat and the length ofburn you should expect from various settings.Most installations do not require a large amount ofcombustion air, especially if adequate draft is available.Do not for any reason attempt to increase the firingof your heater by altering the air control adjustmentrange outlined in these directions.Use the following air control settings as a starting pointto help determine the best settings for your installation.Each is described as a fraction of the total distance thelever may be moved from right to left.Encore Control SettingsBurn Rate Primary Air ControlLow From far right to 1/3the distance to leftMediumFrom 1/3 to 2/3 the distanceto leftHighFrom 2/3 the distanceto left to far leftConditioning Your StoveCast iron is extremely strong, but it can be broken witha sharp blow from a hammer or from the thermal shockof rapid and extreme temperature change.The cast plates expand and contract with changes intemperature. When you first begin using your Encore,minimize thermal stress by allowing the plates to adjustgradually during three or four initial break-in fires followingSteps 1-3 below.Starting and Maintaining a FireBurn wood or coal directly on the grate. Do not elevatethe fuel.The damper must be open when starting a fire orwhen refueling.Do not use chemicals or fluids to start the fire. Donot burn garbage or flammable fluids such as gasoline,naptha, or engine oil.1. Open the stove damper, and open the primary aircontrol fully.2. Place several sheets of crumpled newspaper in thestove. Place on the paper six or eight pieces of drykindling split to a finger-width size, and on the kindlinglay two or three larger sticks of split dry woodapproximately 25-51 mm (1-2”) in diameter.Never use gasoline-type lantern fuel, kerosene, charcoallighter fluid, or similar liquids to start or “freshen2000971

Light the newspaper ST263 and close the door. Graduallybuild up the fire starting by adding a firea few 76-127 mm (3-5”)diameter splits.12/99If this is one of the first few “breakin”fires, let the fire burn brightly, and then let it dieout.During the break-in fires, don’t let the stove get hotterthan 260° C (500° F) as measured on an optionalstove-top thermometer. Adjust the air control lever asnecessary to control the fire.Some odor from the stove’s hot metal, the paint, andthe cement is normal for the first few fires.NOTE: Some chimneys need to be “primed,” orwarmed up, before they will draw sufficiently to starta fire. To correct this situation, roll up a couple piecesof newspaper, place them on top of the kindling andtoward the back of the stove, light them, and closethe doors. This will encourage smoke to rise rapidly,encouraging a good draft.Once the draft is established, open the front door andlight the rest of the fuel from the bottom. Do not light themain bed of fuel until the chimney begins drawing, andrepeat the procedure as often as necessary if the initialattempt is unsuccessful.ST264Fig. 25 Add larger pieces of wood as the fire begins to burnwell.4. If your Encore has been broken-in previously usingSteps 1-3, continue to build the fire gradually. Addlarger wood with ST264 a diameter of 76-102 mm (3-4”). Ifgood fire200097112/99burning wood, continue adding split logs of this sizeto the briskly-burning fire until there is a glowingember bed at least 76 mm (3”) deep. If burning coal,begin adding small amount directly on the kindling toestablish a burning coal pile.5. Close the damper when the griddle temperaturereaches 230° C (450° F).6. Adjust the air control for your desired heat output.Refuel While the Embers Are Still HotAlways wear stove gloves to protect your hands fromhot surfaces while refueling. The following guidelineswill help you achieve the best results.De-ash the stove by stirring the fuel bed to allow ashto fall through the grate. It is important that plenty of airis able to circulate through the charcoal bed. Do notbreak, pound or compress the charcoal into very smallpieces. Larger pieces of charcoal allow more air tocirculate under the wood and result in the fire revivingmore quickly.ST264aFig. 26 Add full-size logs when the kindling has burned downto a bed of embers.When burning coal it is important to de-ash the coalbedto maintain steady heat output. Use the slicer/pokersupplied with the Encore ST264a to stir and break up the coalpile removing as muchadd woodash asfirepossible.Add fuel while the 11/00 stove still has plenty of glowingembers to rekindle the fire. Include a few small piecesof wood in the new fuel load to help the stove quicklyregain operating temperature.Use this sequence as a guide to successful refueling:1. Open the damper.NOTE: Door handles can be hot. A glove has been includedwith your stove.We recommend using this glovewhenver operating door or damper controls and especiallywhen operating the top griddle.2. De-ash the stove as described above. Open thefront doors and check the level of ash in the ashpan. Empty the pan if necessary and replace it in thestove. Close the front doors.3. Open the griddle, load the wood (smaller piecesfirst), and close the griddle. When burning coal, it is15
