Venting
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.
Framing Vent in Combustible Walls &
Ceilings
When penetrating through combustible walls and
ceilings, frame a minimum of 10 x 10 inches opening
and ensure that the insulation is kept clear of the vent
pipe using either a wall thimble or an attic insulation
shield. Follow the installation instructions supplied with
the individual venting components.
