EXTERIOR INSTALLATION
TEE & WALL SUPPORT
Three wall supports are available. All three are
adjustable (ATSC), (URES), and (ATS)
INSTALLATION NOTES
If possible, install an interior chimney as it will pro-
vide better performance than an exterior chimney.
In areas with continuous temperatures below -18°C
(0°F), the use of an exterior chimney may result in
operating problems such as poor draft, excessive
condensation of combustion products and rapid
accumulation of creosote when connected to a
wood burning appliance. If you do install an exteri-
or chimney, we recommend that you surround the
chimney within 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. In exterior installations, the chimney must be
stabilized at 8-foot intervals. A wall band (AWBU)
or Offset Support (URES) can be used for this
purpose.
3. The adjustable supports (ATSC) and (URES) can be
installed either below or above the insulated tee.
4. IMPORTANT: To ensure minimum clearances to
stovepipe, the insulated pipe length (passing
through the wall) must project beyond the inside
wall by a minimum of 5". The maximum projection
length is 24". See Figure 16.
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".
6. If an exterior installation is to be enclosed, (see
Figure 20) allow for access to base of tee to fa-
cilitate required cleaning.
