Vermont Castings Madison

Double-wall Chimney Connectors

The Madison is approved for installation in the U.S. and Canada with double-wall chimney connectors that have been tested and listed for use with solid-fuel burning appliances by a recognized testing laboratory.

Follow the instructions for assembling and install- ing double-wall connectors provided by the manufac- turer of the double-wall chimney. To ease assembly and help assure safety, use chimney components manufactured by a single source.

NOTE: For installations using double-wall connectors, minimum clearances must conform to those listed in the clearance chart on Page 12.

Single-wall Chimney Connectors

•Beginning at the flue collar of the stove, assemble the chimney connector. Insert the first crimped end into the stove’s flue collar, and keep each crimped end pointing toward the stove. Using the holes in the flue collar as guides, 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.

•Secure each joint between sections of chimney connector, including telescoping joints, with at least three sheet metal screws. The predrilled 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.

•Secure the chimney connector to the chimney. Instructions for various installations 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 connector are available to simplify assembly. Slip pipes eliminate the need to cut individual connector sections. Consult your local dealer about these special connector sections.

Securing the Single-wall Connector to a

Prefabricated Chimney

Follow the installation instructions of the chimney manufacturer exactly.

Special adaptors are available from your local dealer to make the connection between the prefabri- cated chimney and the chimney connector. The top of such adaptors attach directly to the chimney or to the chimney’s ceiling support package. The bottom of the adaptor is secured to the chimney connector.

The adaptor forms a union between the chimney and chimney connector that ensures any soot or creosote falling from the inner walls of the chimney will stay inside the chimney connector.

Securing the Single-wall Connector to a

Masonry Chimney

The Madison may be connected to either a freestand- ing masonry chimney or to a fireplace masonry chimney.

Freestanding Installations

If the chimney connector must pass through a com- bustible wall to reach the chimney, follow the recom- mendations for Wall Pass-Through construction on pages 7-8.

The opening through the chimney wall to the flue - the "breech" – must be lined with a ceramic or metal thimble which is securely cemented in place. (Fig. 5)

A metal pipe section called the “thimble sleeve,” slightly smaller in diameter than standard connector and the thimbles, will allow the removal of the chimney connector system for inspection and cleaning. Thimble sleeves are available from your local dealer.

To install a thimble sleeve, slide it into the breech until it is flush with the inner flue wall. Be sure that it does not extend into the flue passage where it 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.
