VENTING INSTALLATION
Continued
WARNING: Do not recess vent termination in to
any wall. This will cause a fire hazard.
3. Attach vent pipe assembly to the fireplace. Set fireplace in
front of it’s permanent location to insure minimum clearances.
Mark the wall for a 10" square hole (for noncombustible ma-
terial such as masonry block or concrete, a 7
1 /
2
" diameter
hole is acceptable). See Figure 22. The center of the hole
should line up with the center-line of the horizontal rigid vent
pipe. Cut a 10"x10" (254mm x 254mm) square hole through
combustible exterior wall (7
1 /
2
" [190mm] diameter hole if
noncombustible). Frame as necessary (see Figure 22).
4. Noncombustible Exterior Wall: Apply a bead of non-harden-
ing mastic around the outside edge of the vent cap. Position the
vent cap in the center of the 7
1 /
2
" hole on the exterior wall with
the arrow on the vent cap pointing up. Attach the vent cap with
four wood screws provided (see Figure 23).
Note : Replace the
wood screws with appropriate fasteners for stucco, brick, con-
crete, or other types of siding.

Combustible Exterior Wall: For vinyl siding, stucco, or wood
exteriors, a siding standoff must be installed between the vent
cap and exterior wall. The siding standoff prevents excessive
heat from damaging siding materials. Siding materials must be
cut to accommodate standoff. Bolt the vent cap to the stand-
off. Apply non-hardening mastic around outside edge of the
standoff. Position the standoff/cap assembly in the center of
the 10" square hole and attach to exterior wall with wood screws
provided (see Figure 24). The siding standoff must sit flush
against the exterior fascia material.
5. Conbustible Exterior Wall Only: Slide the interior wall firestop
over the vent pipe before connecting the horizontal run to the
vent cap (see Figure 25).
6. Carefully move the stove with vent assembly attached toward
the wall and insert the vent pipe into the horizontal termina-
tion. The pipe overlap should be a minimum of 1
1 /
4
". Apply
silicone to the connection. Fasten all vent connections with
screws provided.
7. Conbustible Exterior Wall Only: Slide the wall firestop against
the interior wall surface and attach with screws provided (see
Figure 25).
