" 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: The four wood screws provided
should be replaced with appropriate fas-
teners for stucco, brick, concrete or other
types of sidings.
For vinyl
siding, stucco or wood exteriors, a siding
standoff may be installed between vent
cap and exterior wall. The 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 the
center of the 10" square hole and attach
to exterior wall with wood screws provided
(see Figure 11). Siding standoff must sit
ush against exterior fascia material.
