Prefabricated Chimneys

A prefabricated metal chimney must be one tested and listed for use with solid-fuel burning appliances.

A horizontal connector run should be inclined 1/4” per foot (20 mm per meter) from the stove toward the chimney. The recommended maximum length of a hori- zontal run is 3 feet (1m) and the total length of chimney connector should be no longer than 8 feet (2.5m).

Chimney Height

For proper draft and good performance, the chimney should extend at least 16’ (5 m) above the flue collar of the stove.

The chimney must also extend at least 3’ (914 mm) above the highest point where it passes through a roof, and at least 2’ (610 mm) higher than any portion of a building within 10’ (3 m). (Fig. 2)

Chimney Size

The Model 2478 heater should be vented into a ma- sonry chimney with a square flue with nominal flue size of 8” x 8” (203 x 203 mm), or a round flue with nominal flue size of 6” (152 mm).

Chimney liners larger than 8” x 12” (203 x 305 mm) may promote rapid cooling of smoke and reduction in draft, especially if they are located outside the home. These large chimneys may need to be insulated or have their flues relined for proper stove performance.

Accessories to help make the connection between stainless steel chimney liners and the stove are avail- able through your local dealer.

Guidelines for Installing the Chimney Connector

The chimney connector is the single-wall pipe, or listed and approved double-wall pipe that connects the stove to the chimney. The chimney itself is a masonry or prefabricated structure that encloses the flue. Chimney connectors are used only to make the connection from the stove to the chimney.

Do not pass the chimney connector through a combus- tible wall, floor, or ceiling, through an attic or roof space, or through a closet or similar concealed space. If pas- sage through a combustible wall is unavoidable, follow the recommendations in the following section on Wall Pass-Throughs. Keep the passage as short and direct as possible, with no more than two 90 degree turns.

Two Types of Connector

You may use either a single-wall steel connector of the size and gauge described below, or a listed and ap- proved double-wall connector.

Single-Wall Connector

The single-wall chimney connector should be made of 24 gauge or heavier steel, and must have a minimum internal diameter of 6” (150 mm) for model 2478.

Install single-wall chimney connector not less than 18” (450 mm) from the ceiling.

In cathedral ceiling installations, extend the prefabri- cated chimney downward to within 8 feet (2.5 meters) of the stove. The entire chimney connector should be exposed and accessible for inspection and cleaning.

Do not use galvanized chimney connector; it cannot withstand the high temperatures that can be reached by smoke and exhaust gases and it may release toxic fumes under high heat.
