Venting
Top or Rear Facing Outlet
The 530 appliance is supplied standard with a rear
facing direct vent outlet and may be converted to a top
facing direct vent outlet with no extra parts required—
see .
The 530 appliance is supplied with a smooth 4 x 6-5/8”
co-axial collar and will require a 817VAK Vent Adapter to
convert the collar to a twist-lock type collar.
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 38–39.
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 18–19 and
Approved Venting Components
pages
38–39.
Follow the installation instructions supplied with the
individual venting accessories.
Do not mix components from di
ff
erent manufacturers.
Do not cut pipe lengths; use adjustable lengths instead.
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 shield. 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.
Co-Linear Direct Vent Installations for Free
Standing or Recessed Installations (
fl
exible
piping)
Converts the appliance outlet collars to accept two
3-inch diameter
fl
exible liners for installation into
existing solid-fuel burning
fi
replaces and chimneys.
Requires a co-linear adapter at the appliance and either
a co-linear terminal or co-linear-to-co-axial terminal at
the top of the chimney. Sidewall co-linear installation is
also possible using a 720WSK Sidewall Terminak Kit—
see instructions packed with the kit. A list of approved
venting accessories is shown on ....................

All horizontal pipe runs must be graded 1/4 inch
per foot upwards in the direction of the exhaust
fl

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