Encore 1450 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.
Encore 1450 Non-Catalytic Woodburning Stove Masonry Chimneys What Kind of Chimney to Use You must connect the Encore to a code-approved masonry chimney with a flue liner, to a relined masonry chimney that meets local codes, or to a prefabricated metal chimney that complies with the requirements for Type HT chimneys in the Standard for Chimneys, Factory-Built, Residential Type and Building Heating Appliance, UL 103. (Fig. 3) The chimney and chimney connector must be in good condition and kept clean.
Encore 1450 Non-Catalytic Woodburning Stove 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. 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.

Encore 1450 Non-Catalytic Woodburning Stove Floor Protection Wall Stud A tremendous amount of heat radiates from the bottom plate of your 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.

Encore 1450 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.
Encore 1450 Non-Catalytic Woodburning Stove Air must be able to flow between the wall and the shield. At least 50% of the bottom 1" (25 mm) of the shield should be open and the shield must be open at the top. Use metal screening, as in Figure 14, to keep stray objects from falling behind the shield. The shield for a top-exit stove must extend 10" (254 mm) above the top of the stove; for a rear exit configuration, the shield must be 36” (914 mm) high.

Encore 1450 Non-Catalytic Woodburning Stove Assembly Adjust the Leg Levellers Set Up Your Stove Cast iron stoves are heavy, and it will take two to four people to move your Encore into position. Wipe the protective coating of oil from the griddle with a clean dry rag or a paper towel. Lift the stove slightly so there is no weight on the leg while making the adjustment. Reverse the Flue Collar (If Necessary) Install the handle on the griddle. First, place the griddle upside ST516 down at the edge Fig.

Attach the fan assembly at the bottom edge of the inner back with two (2) 1/4-20 x 3/4” hex head screws and one (1) 1/4” star washer. 3. Attach snapstat to the mounting holes on the underside of the bottom with two (2) 1/4-20 pan head screws. 4. Attach the rheostat holder, (provided with stove), under the right wing of the bottom heat shield with two (2) #10 sheet metal screws. 5.
Encore 1450 Non-Catalytic Woodburning Stove Operation The Encore NC Controls Two controls regulate the performance of the Encore NC: a primary air control supplies oxygen for the fire, and a damper directs air flow within the stove to activate and deactivate the non-catalytic combustion system. Except when starting or reviving a fire, adding fuel or when the stove doors are open, the damper should always be closed.
Encore 1450 Non-Catalytic Woodburning Stove The Encore may be used as a fireplace with the front doors open or removed, BUT only when it is equipped with an 8” (203 mm) flue collar and only when the optional spark screen is placed correctly in the opening to protect against the possibility of sparks and embers leaving your stove. The test standard for your stove when it is operated in this mode is UL 737. Handle Use only the Encore spark screen, item #0127, with your Encore.
Encore 1450 Non-Catalytic Woodburning Stove 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.
Encore 1450 Non-Catalytic Woodburning Stove 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.
Encore 1450 Non-Catalytic Woodburning Stove Ash Removal and Disposal You should remove ash before it reaches the top of the ash pan. 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.
Encore 1450 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.
Encore 1450 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 encourage good draft and minimize creosote production.
Encore 1450 Non-Catalytic Woodburning Stove Maintenance 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.
Encore 1450 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.
Encore 1450 Non-Catalytic Woodburning Stove 3. Determine the correct length of the appropriatesized gasket by laying it out in the channel. Allow an extra 1-2” (25-50 mm), and mark the spot to be cut. (Fig. 47) 4. Remove the gasket from the channel, place it on a wood cutting surface, and cut it at the marked spot with a utility knife. Twist the ends slightly to keep the gasket from unraveling. 5. Lay an unbroken 1/8” (3mm) bead of gasket cement in the newly-cleaned channel. 6.
Encore 1450 Non-Catalytic Woodburning Stove Maintenance Schedule The Chimney Connector The Stove 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.
