of chimney connector and secure it to the flue collar
with three #10 x 1/" 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 3 mm (1/8") 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 connector
are correct distances from nearby combustible mate-
rial.
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 connector
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.

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 Page 7.
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.
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 con-
nector 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 5-51 mm (1-")
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.
In this installation, the chimney connector enters the
fireplace flue though a thimble located above the fire-
place. The liner of the fireplace chimney should extend
at least to the point at which the chimney connector
enters the chimney. Follow all the guidelines for install-
ing a chimney connector into a freestanding masonry
chimney, and pay special attention to these additional
points:
•
Check the stove and chimney connector clearances
to combustible mantel and trim materials. If neces-
sary, use a combination of mantel, trim, and connec-
tor heat shields to provide the required clearances.
•
Double-check connector clearance to the ceiling.
•

If your fireplace opening height is at least 546 mm
(1¹⁄₂"), you may install a stove through the opening

using a "positive connection" kit available from your
local dealer. These kits provide a secure connection
between the stove flue collar and the chimney flue.
Confirm that the stove location is within the required
clearance specifications for the mantel and surrounding
fireplace trim. Refer to Page 11.
Floor protection requirements also apply to fireplace
installations.
