Chimney Connector Guidelines

A chimney connector is the single-wall pipe that con- nects 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.

Single-wall connectors should be made of 24 gauge or heavier steel. Do not use galvanized connector; it cannot withstand the high temperatures that can be reached by smoke and exhaust gases, and may re- lease toxic fumes under high heat. The connector may be 6” (152 mm) or 8 “ (203 mm) in diameter.

If possible, do not pass the chimney connector through a combustible wall or ceiling. If passage through a com- bustible wall is unavoidable, refer to the section on Wall Pass-Throughs. Do not pass the connector through an attic, a closet or similar concealed space. The whole connector should be exposed and accessible for in- spection and cleaning.

In horizontal runs of un shielded chimney connector, maintain a distance of 30” (762 mm) from the ceiling. Keep it as short and direct as possible, with no more than two 90° turns. Slope horizontal runs of connector upward 1/4” per foot (6mm per meter) going from the stove toward the chimney. The recommended maxi- mum length of a horizontal run is 3’ (1 m), and the total length should be no longer than 8’ (2.4 m). In cathedral ceiling installations, extend the prefabricated chimney downward to within 8’ (2.4 m) of the stove. This will help maintain a good draft by keeping the smoke warm, so that it rises readily.

Wear gloves and protective eyewear when drilling, cut- ting or joining sections of chimney connector.

Single-wall Chimney Connectors

Begin assembly at the flue collar of the stove. Insert the first crimped end into the stove’s flue collar, and keep each crimped end pointing toward the stove.

(Fig. 5) Using the holes in the flue collar as guides, drill 1/8” (3mm) holes in the bottom of the first sec- tion of chimney connector and secure it to the flue collar with three #10 x 1/2” sheet metal screws.

Lift off the griddle, and shield the stove’s surface between the griddle opening and the front of the flue collar to protect the finish when you drill the front hole.

Fasten each joint between sections of chimney connector, including telescoping joints, with at least three (3) sheet metal screws. The pre-drilled holes in the top of each section of chimney connector serve

as guides when you drill 1/8” (3mm) holes in the bot- tom of the next section.

Fasten the chimney connector to the chimney. Instructions for various installations follow. Figure 6 illustrates the general layout of chimney connector parts.

Be sure the installed stove and chimney connector are correct dis-

tances from nearby

Securing the Single-wall Connector to a

Prefabricated Chimney

Follow the installation instructions of the chimney manufacturer exactly as you install the chimney. The manufacturer of the chimney will supply the acces- sories to support the chimney, either from the roof of the house, at the ceiling of the room where the stove is installed, or from an exterior wall.

Special adapters are available from your local dealer to make the connection between the prefabricated chimney and the chimney connector. The top of such adapters attaches directly to the chimney or to the chimney’s ceiling support package, while the bottom of the adapter is screwed to the chimney connector.

These adapters are designed so the top end will fit out- side the inner wall of the chimney, and the bottom end will fit inside the first section of chimney connector.

Securing the Single-wall Connector to a

Masonry Chimney

Both freestanding masonry chimneys and fireplace ma- sonry chimneys may be used for your installation.

Freestanding Installations

If the chimney connector must pass through a combus- tible wall to reach the chimney, follow the recommen- dations in the Wall Pass-Through section that follows. The opening through the chimney wall to the flue (the “breech”) must be lined with either a ceramic or metal cylinder, called the “thimble”, which is cemented
