" round hole and attach to the exterior
wall with four screws.
Note:
The four wood
screws provided should be replaced with
appropriate fasteners for stucco, brick,
concrete or other types of sidings. 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.
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 damag-
ing the siding materials. Siding material
must be cut to accommodate standoff.
Bolt the vent cap to the standoff. Apply
non-hardening mastic around outside
edge of standoff. Position the standoff/
cap assembly in the center of the 11
