of 1-1/4 inches. Use the two sheet metal
screws provided to secure the Pipe
Section to the back of the Termination
Cap. The Wall Thimble Cover will cover
the screw heads (Fig. 8).
Step 7. Slide the Wall Thimble Cover
up to the wall surface and attach to
the wall with screws provided (Fig. 9).
Apply optional decorative brass trim to
Wall Thimble Cover, if desired.
SNORkELS
For installations requiring a vertical
rise on the exterior of the building,
14-inch and 36-inch tall Snorkel
Terminations are available (Fig. 10).
Follow the same general installation
procedures as used for a standard
Horizontal Termination. The standard
Wall Thimble or Wall Firestop can
be used with the Snorkel, but the
exterior plate will overhang the edges
of the Snorkel. However, a universal
Wall Thimble is available for use
with the Snorkel that is not visible
on the exterior of the building (46 or
58DVA-WTU). To install the Universal
Wall Thimble, insert the thimble from
the interior of the house and adjust
the length of the tube to ensure it
touches the backside of the Snorkel
when installed (Fig. 10). Secure the
tube in place using 2 sheet metal
screws. Mount the Wall Thimble
in place. Attach the Snorkel to the
wall using wood screws or other
appropriate fasteners, depending
on wall construction. If the Snorkel
Termination must be installed below
grade level, (e.g. in a basement
application), proper drainage must
be provided to prevent water from
entering the Snorkel Termination
(Fig. 11). Do not attempt to enclose
the Snorkel within the wall or any
other type of enclosure.

VINYL SIDING INSTALLATION
The Vinyl Siding Standoff prevents
excessive heat from potentially warping
or melting the vinyl siding material.
Vinyl Siding Standoffs are not used with
Snorkels. The Vinyl Siding Standoff is
available in either a 1-piece version or a
4-piece version.
