Top or Rear Facing Outlet
This appliance is supplied with a top vent outlet which
can be
fi
eld-converted to a rear facing vent outlet. See
page 23 for more information.
Vent Material
This appliance is approved for installation using
4 x 6-5/8-inch co-axial direct vent pipe and accessories
as listed in
Approved Venting Components
pages
41–42. Follow the installation instructions supplied
with the individual venting accessories.
This appliance may also be converted to co-linear
venting with two 3-inch pipes for use in solid-fuel
burning
fi
replaces and chimneys using approved
adapers and accessories. See
Co-Linear Conversion
pages 21–22 and
Approved Venting Components
pages 41–42.
Vent Sealing
Seal all outer co-axial 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 1-1/4 inch
overlap.
Wall Thickness
The appliance vent is suitable for penetrating a
combustible wall assembly up to 14 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.
Vent Penetration Through Walls & Ceilings
Combustible
When penetrating through combustible walls and
ceilings, frame a minimum of 10 inches x 10 inches
opening and ensure that the insulation is kept clear
of the vent pipe using either a wall thinble or an attic
insulation shiedl. Follow the installation instructions
supplied with the individual venting components.
Non-combustible
If the wall is totally non-combustible (e.g. masonry
block or concrete), mark for a 7-inch circular hole.
In both cases, the center of the hole should line up with
the center line of the horizontal vent.
