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

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

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.
