6. Noncombustible Exterior Wall: Position
horizontal vent cap in center of the 8
round hole and attach to exterior wall with
four screws (see Figure 10). Note: The four
wood screws provided should be replaced
with appropriate fasteners for stucco, brick,
concrete or other types of sidings. 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.
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 the 11 / " square hole and attach to

exterior wall with wood screws provided
(see Figure 11). Siding standoff must sit
flush against exterior fascia material.
7. Connecting Vent Cap with Horizontal
Vent Pipe: Slide wall firestop over vent
pipe before connecting horizontal run to
vent cap (see Figure 12).
Carefully move fireplace, with vent as-
sembly attached, toward wall and insert
vent pipe into horizontal termination. The
pipe overlap should be a minimum of 1
(see Figure 13, page 11).
