Venting; Materials Overview - Valor LX1 Installation Manual

Venting

Vent Material
This unit is approved for installation using 4 x 6-5/8-inch
co-axial direct vent pipe and accessories as listed in the
"Approved Venting Components" table starting on page
53 of this manual. Follow the installation instructions
supplied with the individual venting accessories.
This unit may also be converted to co-linear venting
with two 3" pipes for use in solid-fuel burning fi replaces
and chimneys using approved adapters and accesso-
ries. See "Approved Venting Components" on page 53.
Vent Sealing
Seal all outer coaxial pipe and elbow joints, including
sectioned elbow joints, using high quality, high
temperature 2 inch wide self-adhesive aluminum foil
tape (Nashua-322-2 brand or similar). Wrap the tape
completely 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.
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.
Tape all joints
(including all
elbow joints)

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 bar-
rier.
• 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.
