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 57.
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 57
For installations requiring a vertical rise on the exterior of the
building, 14-inch and 36-inch tall Snorkel Terminations, as shown in
Figure 58a
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 58b.
Do not attempt to enclose
the Snorkel within the wall or any other type of enclosure.
