Quadra-Fire • Columbia Bay • 250-5195 Rev. K
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 termination cap 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
)
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 (part #841-0670) 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
vent termination. The vinyl siding standoff prevents
excessive heat from possibly melting the vinyl siding
material. Vent terminal shall not be recessed into a
wall or siding. Remove siding from the area where the
standoff will be located..
