This will cause a fire hazard.
6.
Noncombustible Exterior Wall:
Position the
horizontal vent cap in the center of the 8 1 /
2
"
round hole and attach to the exterior wall with
four wood screws provided. Before attaching
the vent cap to exterior wall, run a bead of
non-hardening mastic (pliable sealant) around
the outside edges to make a seal between it and
the outside wall. Note: The four wood screws
provided should be replaced with appropriate
fasteners for stucco, brick, concrete or other
types of sidings.
Combustible Exterior Wall:
For vinyl siding,
stucco or wood exteriors, a siding standoff may
be installed between the vent cap and exterior
wall. The siding standoff prevents excessive
heat from damaging the siding materials.
Siding material must be cut to accommodate
standoff. Bolt the vent cap to the standoff. Ap-
ply non-hardening mastic around outside edge
of standoff. Position the standoff/cap assembly
in the center of the 10 3 /
4
" square hole and attach
to exterior wall with wood screws provided (see
Figure 11). The siding standoff must sit flush
against the exterior fascia material.
7.
Combustible Exterior Wall Only:
Slide the wall
firestop over the vent pipe before connecting
horizontal run to vent cap (see Figure 12).
8. Carefully move fireplace, with vent assembly
attached, toward wall and insert vent pipe
into horizontal termination. The pipe overlap
should be a minimum of 1 1 /
4
" (see Figure 13,
page 12).
9.
Combustible Exterior Wall Only:
Slide wall
firestop against interior wall surface and attach
with screws provided. See Figure 13, page 12,
for horizontal termination details.
10. Place fireplace into position and shim with
noncombustible material if needed. Nail or
screw side flanges to framing to secure unit in
place. IMPORTANT: Make sure fireplace is
level before securing. If fireplace is not level
it will not work properly.
