•Secure the chimney connector to the chimney. Instructions for various installation follow.

•Be sure the installed stove and chimney connector are correct distances from nearby combustible material.

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

Securing the 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 adapters are available from your local dealer to make the connection between the prefabricated chim- ney and the chimney connector. The top of such adapters attach 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 outside the inner wall of the chimney, and the bottom end will fit inside the first section of chimney connector. Any soot or creosote falling from the inner walls of the chimney will stay inside the chimney connector.

Securing the Connector to a Masonry Chimney

The Seneca may be connected to either a freestanding masonry chimney or a masonry fireplace chimney.

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 ÒbreechÓ) must be lined with either a ceramic or metal cylinder, called the ÒthimbleÓ, which is securely ce- mented in place. (Fig. 5) Most chimney breeches incorporate thimbles, but check to be sure the fit is snug and the joint between thimble and chimney wall firmly cemented.

A special piece called the "thimble sleeve," slightly smaller in diameter than the standard connector and most thimbles, will ease the removal of the chimney connector system for inspection and cleaning. (Fig. 6) Thimble sleeves should be available from your local dealer.

To install a thimble sleeve, slide it into the breech until it is flush with the inner flue wall. Do not extend it into the actual flue passage, as that could interfere with the draft.

The thimble sleeve should protrude 1-2" (25-50 mm) into the room. Use furnace cement and thin gasketing to seal the sleeve in place in the thimble. Secure the chimney connector to the outer end of the sleeve with sheet metal screws.
