Keep the horizontal run of chimney connector as short 
and direct as possible, with no more than two 90° turns.  
Slope horizontal runs of connector upward 1/4” per foot 
(20 mm per m) going from the stove toward the chim-
ney. The recommended maximum length of a horizontal 
run is 3’ (914 mm). The recommended total length of 
chimney connector is 8’ (2.4 m).  
In cathedral ceiling installations, extend the prefabri-
cated chimney down to within 8’ (2.4 m) of the stove.

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 burn-
ing 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 chim-
neys from the same manufacturer makes the assembly 
and installation straightforward.

NoTe:  For installations using double-wall con-
nectors, minimum clearances must conform to the 
listed clearances in the clearance chart on page 14.

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 be-

tween sections of chimney 
connector, including tele-
scoping 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.

  The crimped end of 

the connector points toward 
stove.

• 

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 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.
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 attaches directly to the chimney or to the chimney’s 
ceiling support package, while the bottom of the adap-
tor 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 fall-
ing 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.

If the chimney connector must pass through a combus-
tible wall to reach the chimney, follow the recommenda-
tions in the Wall Pass-through section that follows.
