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.
