Do not recess vent terminal into a wall or
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-hardening mastic around outside edge of the standoff
instead of the vent cap assembly. Use wood screws pro-
vided to attach the standoff. Figure 13
