5. Installation requires a minimum of 6 in. (152 mm)
horizontal run of vent with a 1/4 in. (6 mm) rise run
towards the termination. Each 1 ft. (305 mm) of
horizontal venting must include a 1/4 in. (6 mm) rise.
Never allow the vent to run downward. This could cause
high temperatures and may present the possibility of
a fire. 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 10.
6. 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. (356 mm) and a 36
in. (914 mm) 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.
7. Position the horizontal termination cap in the center of
the 10 in. x 10 in. (254 mm x 254 mm) 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
).

10. If you are installing termination cap HHW2, the pipe
will be off center on flashing). Ensure that proper
clearances to combustible materials are maintained.
If
you are using an approved termination cap other than
HHW2 (part #841-0670) on a building with vinyl siding,
a vinyl siding standoff should be installed between the
termination cap and the exterior wall (
Figure 5.8,
on
the next page). Follow manufacturer’s instructions for
attaching the vinyl siding standoff to the horizontal
termination cap. The vinyl siding standoff prevents
excessive heat from possibly melting the vinyl siding
material. The vent terminal cap shall not be recessed
into a wall or siding. Remove siding from the area
where the standoff will be located.

8. The four wood screws provided should be replaced
with appropriate fasteners for stucco, brick, concrete,
or other types of sidings.
9. 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. (51 mm) closer to the bottom of the square than
the top. Using a framing square, draw a 14 in. x 14 in.
(356 mm x 356 mm) square around the pilot hole. See
Figure 5.7.
