chimney connector guidelines
A chimney connector is the single-wall pipe that con-
nects 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 can be reached by
smoke and exhaust gases, and may release toxic fumes
under high heat. The connector may be 6" (152 mm) or 8
" (203 mm) in diameter.
If possible, do not pass the chimney connector through
a combustible wall or ceiling. If passage through a com-
bustible wall is unavoidable, refer to the section on Wall
Pass-Throughs. Do not pass the connector through an
attic, a closet or similar concealed space. The whole con-
nector should be exposed and accessible for inspection
and cleaning.
In horizontal runs of un shielded chimney connector, main-
tain a distance of 30" (762 mm) from the ceiling. Keep it
as short and direct as possible, with no more than two 90°
turns. Slope horizontal runs of connector upward 1/4" per
foot (6mm per meter) going from the stove toward the chim-
ney. The recommended maximum length of a horizontal
run is 3' (1 m), and the total length should be no longer
than 8' (2.4 m). In cathedral ceiling installations, extend the
prefabricated chimney downward to within 8' (2.4 m) 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. 5)
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. 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 con-
nector, including telescoping joints, with at least three
(3) sheet metal screws. The pre-drilled 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 chimney connector to the chimney. Instruc-
tions for various installations follow. Figure 6 illustrates
the general layout of

parts.

Be sure the installed
stove and chimney
connector are cor-
rect distances from
nearby combustible
materials.
NoTe: Special slip pipes
and thimble sleeves that
form telescoping joints
between sections of
chimney connector 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
Follow the installation instructions of the chimney manufac-
turer exactly as you install the chimney. The manufacturer
of the chimney will supply the accessories 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 chimney
and the chimney connector. The top of such adapters
attaches directly to the chimney or to the chimney's ceil-
ing 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.
Securing the Single-wall connector to a
Both freestanding masonry chimneys and fireplace masonry
chimneys may be used for your installation.
If the chimney connector must pass through a combustible
wall to reach the chimney, follow the recommendations in
the Wall Pass-Through section that follows. The opening
through the chimney wall to the flue (the "breech") must
be lined with either a ceramic or metal cylinder, called
the "thimble", which is cemented securely in place. Most
chimney breeches incorporate thimbles, but the fit must be
snug and the joint between the thimble and the chimney
wall must be cemented firmly.
