Quadra-Fire · Garnet-T · 7016-127F

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

Step 4.
Position the horizontal vent 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) A termination cap with a built-in vinyl siding standoff is

highly recommended on a building with vinyl siding. 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.

Fire Risk.

Explosion Risk.

Combustion Fume Risk.
Use vent run supports per installation instructions.

Connect vent sections per installation instructions.

• Maintain all clearances to combustibles.

• Do NOT allow vent to sag below connection

point to appliance.

• Maintain specified slope (if required).

WARNING

Improper support may allow vent to sag or separate.

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, a snorkel kit 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.
