NOTE:
1. Installation requires a minimum of 6 in. (152mm)
horizontal run of vent with a 1/4 in. (6mm) rise run towards
the termination. Each 1 ft. (305mm) of horizontal venting
must include a 1/4 in. (6mm) rise. 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 8.
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.

(NOTE: If you are installing termination cap HHW2, the
pipe will be off center on the flashing). Ensure that proper
clearances to combustible materials are maintained. If you
are using an approved termination cap other than HHW2
on a building with vinyl siding, a vinyl siding standoff
should be installed between the vent cap and the exterior
wall (Figure 5.8, on the next page). Attach 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 termination cap shall not be
recessed into a wall or siding. Remove siding from the area
where the standoff will be located.
