EXTERIOR INSTALLATION
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
connected 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.
INSTALLATION NOTES
1. The chimney may be enclosed or unenclosed.
2. Maintain 2" clearance to combustible materials.
Do not fill the 2" space around the chimney with
insulation or any other material.
3. A Wall Strap or Re-Support must be used to
secure the chimney to the wall when used on an
exterior wall. Maximum distance between wall
bands is 8'.
4. The horizontal chimney length passing through the
wall must project a minimum of 5" and no more
than 24" beyond the inside wall. Minimum projection
is required to ensure appropriate clearances are
maintained once stovepipe is installed.
5. If an exterior installation is to be enclosed, allow
for access to base of tee to facilitate required
cleaning.
6. The minimum distance between the bottom of the
Tee or Support and any horizontal combustible is
2" by using an insulated tee cap (TCI).
16 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
RE-SUPPORT
When a chimney is used along a wall,
this support may be used to support
the chimney. The height of chimney
supported is shown in supported
height See Table 1.
INSTALLATION INSTRUCTIONS
Install the support as follows (see Figure 18):
Step 1. Assemble the collar to fit your chimney
diameter. Continue to assemble the support
as described in the instructions supplied
with the support.
Step 2. Slip the support down over the chimney
to the proper location.
Step 3. Tighten the collar around the chimney.
Step 4. Attach the support brackets to the wall
using (8) 3" nails or (8) Nº. 10 x 1-1/4" wood
screws.
NOTE: Be sure that the support attaches to a framing
and not merely to dry wall or siding.
Step 5. Continue installing the chimney.
