Encore® 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 clearance requirements. • The floor protector is large enough and is constructed properly to meet all 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.
Encore® 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® Woodburning Stove Chimney Connector Guidelines Single-wall Chimney Connectors 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. • Begin assembly at the flue collar of the stove. Insert Double-wall connectors must be tested and listed for use with solid-fuel burning appliances.

Encore® Woodburning Stove In general, the greatest clearance is required when you place a stove and its connector with no heat shields near a wall with no heat shield. For example, when the Encore is installed parallel to the rear wall and no shields are used, it must be at least 31” (787 mm) from the wall behind it and at least 24” (610 mm) from walls on either side. If the Encore is installed in a corner and no shields are used, the corners of the stove must be at least 24” (610 mm) from nearby walls.
Encore® Woodburning Stove Chimney Connector Heat Shields Chimney Connector Heat Shields should be used whenever the rear heat shield is used, or in any other situation when it is necessary to protect nearby combustibles from the heat of the connector. The ceiling above horizontal runs of chimney connector must be protected as well if the clearance is inadequate.
Encore® Woodburning Stove Alcove Installations Because of their restricted air flow and heat retention characteristics, alcove installations have specific construction requirements and special clearances. No rear stove or chimney connector heat shields are used in alcove installations. Bottom heat shield requirements remain the same as for other installations. alcove installation of the ENCORE is not permitted in Canada.

The draft management information on Page 25 will explain in detail how the features of your installation may help or hinder good draft.
Encore® Woodburning Stove • Remove the ash pan, making sure to keep it level. • To keep the cover from sliding off and to keep ash • • • 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.
Encore® Woodburning Stove uninsulated liner is a second choice - the liner keeps the smoke restricted to its original size, but the smoke still must warm up the air around the liner. This makes the warm-up process take longer. Pipe & Chimney Layout Every turn the smoke 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, to a completely straight chimney. If you’re starting from scratch, use this layout if possible.
Encore® Woodburning Stove 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. 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.
Encore® Woodburning Stove Removing the Glass The left door is slightly different from the right in that one of its retainer clips is located under the door manifold. 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.

Encore® Woodburning Stove If this test indicates a problem, consider other possible factors as well, such as the time of year or a change in the quality of your fuel. In spring and fall, draft is weaker than it is in colder winter weather, and fires can burn sluggishly. Small, hot fires are a good solution under these conditions. Refractory Access Cover Right Wedge Left Wedge Burning “green” (insufficiently seasoned) wood will result in poorer performance than when burning properly seasoned fuel.
Encore® Woodburning Stove 8. If the element is in good condition and clean, re-install it in the stove and replace the refractory access cover. 9. Replace the fireback, install the two wedges, and replace the cast iron hood. 10. Clean the chimney and chimney connector. Operate the stove in your typical manner for two weeks, inspecting the chimney and the chimney connector frequently during this period. The procedure for replacing gaskets is the same regardless of the gasket location. Follow these steps: 1.
Encore® Woodburning Stove 8. Clean any excess cement from around the channel, then let the cement that holds the new gasket dry thoroughly. 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 29-30.
Encore® Woodburning Stove Appendix: Catalytic Combustor In any chemical reaction, including the combustion process, there are certain conditions which must be met before the reaction can take place. For example, a reaction may require a certain temperature, or a certain concentration of the reactants (the combustion gases and oxygen), or a certain amount of time. Catalysts, though not changed themselves during the reaction, have the ability to act at a molecular level to change these requirements.
