NOTE:
(1) Installation requires a minimum of 11 in. (279mm)
horizontal run. Each 1 ft. (305mm) of horizontal vent
run must include a 1/4 in. (6mm) of vertical rise towards
the termination. Never allow the vent to run downward.
This could cause high temperatures and may present
the possibility of a house or structure fire.
(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,
see Figure 4.4 on page 9.
(3) For installations requiring a vertical rise on the exterior
of the building, the HHT RHVK snorkel kit (Part #844-
8921) is available with a 14 in. (356mm) and a 36 in.
(914mm) tall snorkel termination cap. Follow the
same installation procedures as used for standard
horizontal terminations. If the snorkel termination must
be installed below grade (i.e. basement application),
proper drainage must be provided to prevent water from
entering the snorkel termination. Do not backfill around
snorkel termination.

Step 4.
Position the horizontal termination cap in the center of the 10
in. x 10 in. (254mm x 254mm) square hole and run a bead
of non-hardening mastic around its outside edges, so as to
make a seal between it and the wall, attach termination cap
to the exterior wall with the four wood screws provided. The
arrow on the vent cap should be pointing up (Figure 5.6).

NOTES:
(1) The four wood screws provided should be replaced with
appropriate fasteners for stucco, brick, concrete, or
other types of sidings.
(2) Termination cap HHW2 (Part #841-0670) is highly
recommended on a building with vinyl siding, as the
vinyl siding standoff is built in. The pilot hole will be 2 in.
(51mm) closer to the bottom of the square than the top.
Using a framing square, draw a 14 in. x 14 in. (356mm x
356mm) square around the pilot hole in the siding. See
Figure 5.7 on the next page.
Step 3.
For installations using a round support box/wall thimble
(check pipe manufacturer's instructions), mark the wall for a
10 in. x 10 in. (254mm x 254mm) square hole. The center
of the square hole should line up with the center line of the
horizontal pipe, as shown in Figure 5.5. Cut and frame the
hole in the exterior wall where the vent will be terminated. If
the wall being penetrated is constructed of noncombustible
material, i.e. masonry block or concrete, a 7 in. (178mm)
diameter hole is acceptable.
