WARNING: Do not recess
vent termination into any wall.
This will cause a fire hazard.
6. Noncombustible Exterior Wall: Position
horizontal vent cap in center of the 8
round hole and attach to exterior wall
with four wood screws provided. Before
attaching vent cap to exterior wall, run a
bead of non-hardening mastic (pliable
sealant) around outside edges to make a
seal between it and outside wall.
Note: 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 vent
cap and exterior wall. Siding standoff
prevents excessive heat from damaging
siding materials. Siding material must be
cut to accommodate standoff. Bolt vent
cap to standoff. Apply non-hardening
mastic around outside edge of standoff.
Position standoff/cap assembly in center
of 11

See Figure 13, page 12, for horizontal
termination details.
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 fire-
place is level before securing. If fireplace
