double-wall chimney connectors
The Concord is approved for installation in the U.S.
and Canada with double-wall chimney connectors that
have been tested and for use with solid-fuel burning
appliances by a recognized testing laboratory.
Follow the instructions for assembling and installing
double-wall connectors provided by the manufacturer
of the double-wall chimney. To ease assembly and
help assure safety, use chimney components manufac-
tured by a single source.
Note: for installations using double-wall connec-
tors, minimum clearances must conform to those
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. In-
structions for various installations follow.
•
Be sure the installed stove and chimney connec-
tor 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 assembly. Slip pipes
eliminate the need to cut individual connector sections.
Consult your local dealer about these special connec-
tor sections.
Securing the Single-wall connector to a
prefabricated chimney
Follow the installation instructions of the chimney
manufacturer exactly.
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 adapt-
ers attach directly to the chimney or to the chimney’s
ceiling support package. The bottom of the adapter is
secured to the chimney connector.
The adapter 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 Concord may be connected to either a freestand-
ing masonry chimney or to a fireplace masonry chim-
ney.
freestanding installations
If the chimney connector must pass through a combus-
tible wall to reach the chimney, follow the recommenda-
tions 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 connec-
tor 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” (25-51 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.
