NOTE:
Termination cap should pass through the wall firestop from
the exterior of the building. Adjust the termination cap to
its final exterior position on the building.
WARNING:
Termination cap must be positioned so that arrow
is pointing up.
Attach the termination cap with the four wood screws provided.
Before attachment of the termination, run a bead of silicone sealant
rated above 250°F on its outside edge too, so as to make a seal
to the exterior wall.
NOTE:
Wood screws can and should be replaced with appropriate
fasteners for use on stucco, brick, concrete or other types
of siding.
CAUTION:
If exterior walls are finished with vinyl siding (or
materials that could become discolored or warp), it is necessary
to install a vinyl siding standoff.
The vinyl siding standoff will be installed between the vent termination
and the exterior wall. (See Figure 42) This horizontal vent termination
bolts onto the flat portion of the vinyl siding standoff, so an air space
will exist between the wall and the termination cap.
