Noncombustible Exterior Wall:
horizontal vent cap in the center of the 7
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:
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" 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.
