Vent Sealing
Seal all outer coaxial pipe and elbow joints, including
sectioned elbow joints, using high quality, high tem-
perature 2 inch wide self-adhesive aluminum foil tape
(Nashua-322-2 brand or similar). Wrap the tape com-
pletely around all joints and press fi rmly to seal.
A high temperature black silicone sealant may be used
in the outer joints as a substitute to foil tape.
Ensure all the pipe joints have a minimum of 1 ¼ inch
overlap.
Tape all joints
(including all
elbow joints)
Wall Thickness
The appliance vent is suitable for penetrating a
combustible wall assembly up to 8 inches in thickness.
A non-combustible wall can be of any thickness up to
the maximum horizontal run of vent pipe allowed for the
particular installation.

VENTING

Framing Vent in Combustible Walls &
Ceilings (6-5/8" and 8" pipes)
When penetrating through combustible walls and
ceilings, frame a minimum of 10 in x 10 in opening
and ensure that the insulation is kept clear of the vent
pipe using either a wall thimble or an attic insulation
shield. Note that some vent manufacturers' wall thimble
dimensions may require larger framed openings—
follow the installation instructions supplied with the
individual venting components.

Important Installer Notice –
Weather Sealing & Vapor Barriers
It is the installer's responsibility to ensure that vent
installations through exterior walls are caulked and
weatherproofed in such a manner as to:
• Prevent rain water from entering the wall from
the weather side by adequately caulking the
outer vent plate to the exterior wall surface.
• Prevent moisture inside the home from
penetrating into the wall structure by ensuring
the inside wall plate is adequately sealed to the
inside vapor barrier.
• Prevent rain water and moisture from entering
the walls by sealing the joints between the outer
vent tube and the inner and outer wall plates.
We recommend the use of a high quality
polyurethane sealant.
All horizontal pipe runs must be graded 1/4 inch per
foot upwards in the direction of the exhaust fl ow. The
fi nal pipe length, when terminating through the wall
may be graded downwards slightly to prevent water
migration.
