4. Apply a bead of non-hardening mastic around the outside
edge of vent cap. Position the vent cap in the center of hole
on the exterior wall with the word “UP” on the vent cap

is maintained. Attach the vent cap with four wood screws
supplied.

NOTE: Replace the wood screws with appropriate
fasteners for stucco, brick, concrete, or other types
of siding.
For vinyl siding, stucco, or wood exterior use vinyl siding
standoffs between vent cap and exterior wall. The vinyl siding
standoff prevents excessive heat from melting the vinyl siding
material. Bolt the vent cap to the standoff. Apply non-harden-
ing mastic around outside edge of the standoff instead of the
vent cap assembly. Use wood screws provided to attach the
standoff.
See Figure 22.
5. Slide fire stop over the vent pipe before connecting the
horizontal run to the vent cap.
See Figure 23.
