Chimney Connector Guidelines

Achimney connector is the 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.

Single-wall connectors should be made of 24 gauge or heavier steel. Do not use galvanized connector; it cannot withstand the high temperatures that smoke and exhaust gases can reach, and may release toxic fumes under high heat. The connector may be 6" (150 mm) or 8 " (200 mm) in diameter.

If possible, do not pass the chimney connector through a combustible wall or ceiling. If passage through a combustible wall is unavoidable, refer to the section on Wall Pass-Throughs. Do not pass the connector through an attic, a closet or similar con- cealed space. The whole connector should be ex- posed and accessible for inspection and cleaning.

In horizontal runs of chimney connector, maintain a distance of 24" (610 mm) from the ceiling. Keep it as short and direct as possible, with no more than two 90 degree turns. Slope horizontal runs of connector upward 1/4" per foot (20 mm per meter) going from the stove toward the chimney. The recommended maxi- mum length of a horizontal run is 3 feet (1 meter), and the total length of the chimney connector should be no longer than 8 feet (2.5 meters). In cathedral ceiling installations, extend the prefabricated chimney down- ward to within 8 feet (2.5 meters) 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, cutting 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. 4. Use the holes in the flue collar as guides to drill 1/8" (3 mm) holes in the bottom of the first section 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 sheet metal screws. Holes in the top of each section of chimney connector serve as guides when you drill 1/8" (3 mm) holes in the bottom of the next section.

•Fasten the chim-

ney connector to the chimney. Instructions for various installa- tions follow. Fig. 5 illustrates the general layout of chimney connector parts.

•Be sure the

installed stove and chimney connector are correct dis-

tances from nearby combustible materials.

NOTE: Special slip pipes and thimble sleeves that form telescoping joints between sections of chimney connec- tor are available to simplify installations. They often eliminate the need to cut individual connector sections. Consult your local dealer about these special pieces.

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 accesso- ries 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 adaptors are available from the chimney manufacturer to make the connection between the prefabricated chimney and the chimney connector. The top of such adaptors attaches directly to the chimney or to the chimney’s ceiling support package, while the bottom of the adaptor is screwed to the chimney connector.

These adaptors are designed so the top end will fit outside the inner wall of the chimney, and the bottom end will fit inside the first section of chimney connector. When assembled in this way, any soot or
