NOTICE:
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.
NOTICE:
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 52.
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.
Figure 52
For installations requiring a vertical rise on the exterior of
the building, 14-inch and 36-inch tall Snorkel Terminations,
as shown in Figure 53a are available. Follow the same
installation procedures as used for standard Horizontal
Terminations. If the Snorkel Termination must be installed
below grade (i.e. basement applications, proper drainage
must be provided to prevent water from entering the Snorkel
Termination.
See Figure 53b.
Do not attempt to enclose the
Snorkel within the wall or any other type of enclosure.
