Venting - Valor Madrona MF28JN Installation & Owner's Manual

Top / Rear Outlet
This unit is shipped with a top outlet collar which is
fi eld-convertible to rear outlet—see page 31 for

Vent Material
This unit is approved for installation using 4 by 6-5/8
inches co-axial direct vent pipe and accessories—see
list of approved venting pipes and accessories on
pages 44–45.
This unit may also be converted to co-linear (two 3
inches) venting (rear vent only) for use in solid-fuel
burning fi replaces and chimneys using adapters and
accessories—see list of approved venting pipes and
accessories on pages 44–45. Instructions for co-linear
conversion are packaged with the co-linear adapter.
Do not mix components from diff erent vent manufac-
turers. Follow the installation instructions supplied with
the individual venting components.
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)

Venting

Wall Thickness
The appliance vent is suitable for penetrating a
combustible wall assembly up to 14 inches (36 cm)
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 by 10 inches opening
to ensure that the insulation is kept clear of the vent
pipe. Also, seal all joints between the wall plates,
the wall and the vent pipe. Follow the installation
instructions supplied with the individual venting
components.

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.
Important Installer Notice – Weather
Sealing & Vapor Barriers
It is the installer's responsibility to ensure that vent instal-
lations through exterior walls are caulked and weather-
proofed 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.
