Securing the Connector
to a Masonry Chimney
The Seneca may be connected to either a freestanding
masonry chimney or a masonry fireplace chimney.
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 securely ce-
mented in place. (Fig. 5) Most chimney breeches
incorporate thimbles, but check to be sure the fit is
snug and the joint between thimble and chimney wall
firmly cemented.
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”
(3mm) holes in the bottom of the next section.
• Secure the chimney connector to the chimney.
Instructions for various installation 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 con-
nector are available to simplify installations. They can
eliminate the need to cut individual connector sections.
Consult your local dealer about these special pieces.
Securing the 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 accesso-
ries 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 chim-
ney and the chimney connector. The top of such
adapters attach 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
outside the inner wall of the chimney, and the bottom
end will fit inside the first section of chimney connector.
Any soot or creosote falling from the inner walls of the
chimney will stay inside the chimney connector.

Fig. 5 Installing the chimney connector to a lined masonry
chimney.
A special piece called the "thimble sleeve," slightly
smaller in diameter than the standard connector and
most thimbles, will ease the removal of the chimney
connector system for inspection and cleaning. (Fig. 6)
Thimble sleeves should be available from your local
dealer.
To install a thimble sleeve, slide it into the breech until it
is flush with the inner flue wall. Do not extend it into the
actual flue passage, as that 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.
