2. The location of the horizontal vent termination on an
exterior wall must meet all local and national building
codes, and must not be easily blocked or obstructed.
Refer to Pages 10 and 11 for proper Termination
Clearances.
For installations requiring a vertical rise on the exterior
of the building, 14" (356 mm) and 36" (914 mm) tall
snorkel terminations are available. (Fig. 27) Follow the
same installation procedures as used for standard hori-
zontal terminations. If the snorkel termination must be
installed below grade level, (i.e. basement application),
proper drainage must be provided to prevent water from
entering the snorkel termination. (Fig. 28) Do not at-
tempt to enclose the snorkel within the wall or any other
type of enclosure.

Before attaching the vent termination cap to the exte- 8/07
rior wall, run a bead of non-hardening silicone sealant
around the outside edges to make a seal between the
cap and the wall. The arrow on the vent cap should be
pointing up. Ensure proper clearances to combustible
materials are maintained. (Fig. 29)

NOTES:
1. The four (4) wood
screws provided
should be re-
placed with appro-
priate fasteners
for use on brick,
block, concrete or
other types of sid-
ings.
2. For buildings with
vinyl siding or
stucco, another
component must
be used between
the horizontal ter-
mination cap and
the wall surface.
The vinyl sid-
ing standoff prevents excessive heat from possibly
melting the vinyl siding material. Vinyl siding stand-
offs are not required with snorkels. For vinyl wall
installations a 4-piece vinyl siding standoff should
be assembled and installed between the horizontal
termination cap and the exterior wall. (Fig. 30) The
vinyl should be cut away to the outer edges of the
assembled standoff.

IMPORTANT: You must attach the four (4) pieces of
the new vinyl siding standoff to the horizontal termina-
tion cap in specific order to ensure a weather tight fit.
Loosely assemble the four parts, in order, around the
base of the horizontal termination cap. Place the first of
four pieces along the upper edge of the cap, then using
two (2) screws per side, secure each piece to the pre-
drilled holes along both sides of the cap, finally, attach
the final piece to the bottom edge of the cap. Tighten all
screws and mount cap, with all four (4) pieces attached,
directly onto the wall with the four (4) 2¹⁄₂" (64 mm)
screws provided. (Fig. 30)
