Double-wall Chimney Connector:
The listing for the Intrepid II for the U.S. and Canada includes
use of double-wall chimney connectors that have been tested
and listed for use with solid-fuel burning appliances by a
recognized testing laboratory.
Information on assembling and installing double-wall
connector is provided by the manufacturer of the double-
wall pipe. Follow the manufacturer’s instructions exactly
as you assemble the connector and attach it to the stove
and chimney. Using connectors and chimneys from the
same manufacturer makes the assembly and installation
straightforward.
NOTE: For installations using double-wall connectors,
minimum clearances must conform to the listed
clearances in the clearance chart.
Single-wall Chimney Connector:
• 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
s e c t i o n s o f c h i m n e y
c o n n e c t o r, i n c l u d i n g
telescoping joints, with at
least three 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.
• Secure the chimney connector to the chimney. Instructions
for various installations 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 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 Prefabricated
Chimney:
For prefabricated chimneys, follow the installation instructions
of the chimney maker exactly as you install the chimney. The
maker 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.

Freestanding Chimney Installations:
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
“breach”) must be lined with either a ceramic or metal cylinder,
called the “thimble,” which is cemented firmly in place. The
fit must be snug and the joint between the thimble and the
chimney wall must be cemented. (Figure 6)
A special piece called the “thimble sleeve,” slightly smaller
in diameter than standard connector and most thimbles, will
facilitate the removal of the chimney connector system for
inspection and cleaning. Thimble sleeves should be available
from your local dealer. (Figure 5)
To install a thimble sleeve, slide it into the breach until it is
flush with the inner flue wall. Do not extend it into the actual
flue passage, as this 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.
Without a thimble, a suitable length of chimney connector
can be extended through the breach to the inner face of the
flue liner, and cemented securely in place. Additional pieces
of connector are then attached with sheet metal screws.
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 adaptor 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. When assembled in
this way, 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:
For masonry chimneys, both freestanding and fireplace
chimneys may be used for installation of your Intrepid II.
