Vent Material
This unit is approved for installation using
4 x 6-5/8 inches co-axial direct vent pipe and
accessories as listed in the
Approved Venting
Components
section on pages 47–48 of this

fi
replaces and
chimneys using adapters and accessories—see the
Approved Venting Components
section on pages
47–48 of this manual.
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.
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.
Framing Vent in Combustible Walls &
Ceilings
When penetrating through combustible walls and
ceilings, frame a minimum of 10 x 10 inches opening
and ensure that the insulation is kept clear of the vent
pipe using either a wall thimble or an attic insulation
shield. Follow the installation instructions supplied
with the individual venting components.

nal pipe length, when terminating through the wall
may be graded downwards slightly to prevent water
migration.
