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 re-
lease 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
connector should be exposed and accessible for in-
spection and cleaning.
In horizontal runs of un shielded chimney connector,
maintain 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 chimney. The recommended maxi-
mum 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, cut-
ting 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" (3mm) holes in the bottom of the first sec-
tion 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
connector, 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" (3mm) holes in the bot-
tom of the next section.
•
Fasten the chimney connector to the chimney.
Instructions for various installations follow. Figure 6
illustrates the general layout of chimney connector
parts.
•
Be sure the installed stove and chimney connector
are correct dis-
tances from nearby
combustible materi-
als.
NOTE: Special slip
pipes and thimble
sleeves that form tele-
scoping joints between
sections of chimney
connector are avail-
able to simplify instal-
lations. They often
eliminate the need to
cut individual con-
nector sections. Consult your local dealer about these
special pieces.
Securing the Single-wall 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 acces-
sories 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 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 out-
side 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
Masonry Chimney
Both freestanding masonry chimneys and fireplace ma-
sonry chimneys may be used for your installation.

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 "breech") must be lined with either a ceramic or
metal cylinder, called the "thimble", which is cemented
