WARNING
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).
Improper support may allow vent to sag or separate.
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.

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.

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

cap. Follow the same installation procedures as used
for standard horizontal terminations. If the
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.
