Installation

SAFETY NOTICE: IF YOUR ENCORE IS NOT PROP- ERLY INSTALLED, A HOUSE FIRE MAY RESULT. TO REDUCE THE RISK OF FIRE, FOLLOW THE INSTALLATION INSTRUCTIONS. CONTACT LOCAL BUILDING OR FIRE OFFICIALS ABOUT RESTRIC- TIONS AND INSTALLATION INSPECTION REQUIRE- MENTS IN YOUR AREA.

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 con- structed properly to meet all tested requirements.

•You have all necessary permits from local author- ities.

Your local building official is the final authority for ap- proving 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 UL and ULC safety standards, and gives the name of the testing laboratory. 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 areas. Before starting the installation, review your plans with the local building authority. Your local dealer can provide any additional information needed.

For any unresolved installation issues, refer to the National Fire Protection Association’s publication ANSI/ NFPA 211 Standard for Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances. For Canada, the equivalent publication is CSA CAN-B365 Installation Code for Solid Fuel Burning Appliances and Equipment. These standards are the basis for many national codes. They are nationally recognized and are accepted by most local authorities. Your local dealer or your local building official may have a copy of these regulations.

IMPORTANT: FAILURE TO FOLLOW THESE IN- STALLATION INSTRUCTIONS MAY RESULT IN A DANGEROUS SITUATION, INCLUDING A CHIMNEY OR HOUSE FIRE. FOLLOW ALL INSTRUCTIONS EXACTLY, AND DO NOT ALLOW MAKESHIFT COM- PROMISES TO ENDANGER PROPERTY AND PER- SONAL SAFETY.

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 avail- able 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.

Another solution is to install a permanent outside air supply to the stove and/or room. In fact, bringing air for combustion from outside the home directly to the air in- let of the stove is required for new construction in some areas. The Encore NC is equipped with an outside con- nection as standard equipment.

Pressure variations within the house do not affect a stove equipped with an outside air supply, and im- proved 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 6” flue collar on the Encore NC, refer to Figure 2 for suggested chimney heights at various altitudes. Chim- ney height should be measured from the flue collar to the top of the chimney. The recommended minimum chimney height is 16’ (4.9 m).
