CHIMNEY HEIGHT REQUIREMENTS

AND DRAFT

To be sure that your stove burns properly, the chimney draft (static pressure) should be approximately -.04” water column (W.C.) during a low burn and -.10” W.C. during a high burn, measured 6 inches” (152mm) above the top of the stove after one hour of operation at each burn setting. NOTE: These are guidelines only, and may vary somewhat for individual installations.

Your stove was designed for and tested on a 6 inch (152mm) chimney, 12 ft-14 ft (360-420cm) high, measured from the flue collar to the top of the chimney (not including chimney cap). The further your stack height or diameter varies from this configuration, the possibility of performance problems exists. In addition, exterior conditions such as roof line, surrounding trees, prevailing winds and nearby hills can influence stove performance. Your local dealer is the expert in your geographic area and can usually make suggestions or discover solutions that will easily correct your flue draft problem, allowing your woodstove and its flue system to operate correctly and provide safe and economical heat for your home.

A masonry chimney or a listed factory-built UL103 HT Class “A” chimney must be the required height above the roof and any other nearby obstructions. The chimney must be at least 3 ft. (91cm) higher than the highest point where it passes through the roof and at least 2 ft. (61cm) higher than the highest part of the roof or structure that is within 10 ft. (305cm) of the chimney, measured horizontally. See 2-10-3 Rule (Figure 11A)

These are safety requirements and are not meant to assure proper flue draft.

We recommend using a minimum total system height of 12 ft. (360cm), measured from the flue collar to the top of the chimney (not including chimney cap).

Availability of combustion air: A source of air (oxygen) is necessary in order for combustion to take place. It is important to realize that whatever combustion air is consumed by the fire must be replaced. If you are using room air, the air is replaced via air leakage that occurs around windows and under doors, etc. However, in most newly constructed houses, mobile homes, or even existing homes that are fitted with tightly sealed doors and windows, the area from which the combustion air is taken is relatively air tight. In these cases, an outside air source must be made available to feed combustion air from outside the home into the stove. An Outside Air Kit is available for this stove as an option, Part 831-1780. The kit is a requirement for mobile home installations. Check with the local authorities in your area for the requirements in your location.

FLUE SYSTEMS

There are two separate and different parts to a flue system: the chimney connector and the chimney itself.

A.Single wall connector or stovepipe. This must be at least 24 gauge mild steel or 26 gauge blue steel. The sections must be attached to the stove and to each other with the crimped (male) end pointing toward the stove. See Figure 11B. All joints, including the connection at the stove collar, should be secured with 3 sheet metal screws. Make sure to follow the minimum clearances to combustibles as set out on page 6 of this manual. In Canada, where passage through the wall, or partition of combustible construction is desired, the installation shall conform to CAN/CSA-B365.

B.Factory-built listed chimney connector (vented). A listed connector (vented) must be used when installing this unit in a mobile home. A Listed chimney and Listed connector must be used. They must conform to each other to ensure a proper fit and seal.
