INSTALLATION NOTES
This chimney will provide optimum performance
when installed within the heated space of a build-
ing. The consequences of installing the chimney
outdoors, up the exterior wall of a building could
result in:
-Back-drafting during cold weather when the con-
nected appliance is not operating.
-Weak, unstable draft.
-Increased creosote accumulation.
-Increased potential for condensation of water vapor
in the chimney flue.
-Decreased efficiency of the connected appliance.
If you do install an exterior chimney, we recommend
that you enclose it using an insulated enclosure.
1. Maintain 2" clearance to combustible materials.
Do not fill the 2" space around the chimney with
insulation or any other material.
2. A Wall Band
(AWBU)
must be used to secure the
chimney to the wall. Maximum distance between
wall bands is 8 feet.
3. The minimum length of chimney extending past
the inside wall is 5”.
4. The maximum length of chimney extending past
the inside wall is 24”.
5. The distance between the stove pipe and a parallel
combustible wall or ceiling must not be less than
18". The distance between the horizontal stove
pipe and the unshielded vertical wall through which
it passes must not be less than 7”.
(see Figure 11).
6. If an exterior installation is to be enclosed, allow
for access to base of tee to facilitate required
cleaning.
7. The minimum distance between the bottom of
the Tee and any horizontal combustible (including
the ground) is 2”.

INSTALLATION INSTRUCTIONS
Step 1. Determine where the chimney will pass
through the wall.
• For concrete walls cut a hole slightly larger than
the chimney.
• For combustible walls cut and frame a hole 4”
larger than the chimney, midway between the wall
studs (see Table 4 below for sizing).
Normally wall studs are placed at 16” centers.
With the hole midway between them, the support
will fasten to these studs and thus ensure a strong
attachment to the wall.

From inside, put the larger wall-radiation shield over the small
radiation shield. Using a level, make sure that the hole for the
chimney to pass through is horizontal. Screw the radiation shield in
place (see Fig. 20).
Note: The cavity surrounding the radiation shield must be filled with
type R-20 insulation (see Fig. 20).
Attach the clean-out cap to the support's flue
extension using the three (3) metal screws
provided. Make sure that the screws have pierced
through the flue extension.
The cap is in the box with
the insulated tee. Or if an insulated tee cap is used,
twist lock the tee cap to the tee (adjustable support
(XSME) only).
The minimum length of insulated chimney required to
pass through the wall will be thickness plus 7". The
insulated chimney must extend at least 5" into the room
beyond the finished wall. Insert this chimney length in
the side entry of the insulated tee. Turn it clockwise to
lock it in place. Seal this joint by wrapping it with the
aluminium tape supplied with the tee.
Mount the insulated tee on the support so that the
chimney length which will go through the wall is
perpendicular to the side of the support that will fasten
to the wall.
This step will require 2 persons:
Insert the chimney length of this tee-support assembly
into the hole in the wall. Using a level, ensure the tee is
vertical, then attach the support to the wall using (8) Nº.
10 x 1 - 1/4" wood screws or 4" spiral nails (see Fig.
21).
NOTE: To provide sufficient strength, the nails must
be driven into the wall studs. For concrete walls, the
support should be attached using (8) 1/4" x 2" lag bolts.
Attach the flue extension to the horizontal chimney
length using the three (3) metal screws provided.
If the chimney passes through the roof, cut a hole large
enough to provide 2" clearance between the chimney
and the roof. For flat roof, and for sloping roofs, see
chart on page 3.
Stack a chimney length on top of the tee. Turn it
clockwise to lock it in place.
Stack the next chimney length on the first length.
Continue until the required chimney height is reached.
