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 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
