Suggested inspection openings
457mm x 457mm (18" x 18")
• Inspection openings are suggested for the vent intake and exhaust
pipes if they are installed in an enclosure. These openings should
be near the entrance and exit of the vent into the enclosure.
• These openings should be 457mm x 457mm (18" x 18").
• Terminate at least 1.8m (6') from the
combustion air intake of any appli-
ance, and 0.9m (3') from any
other building opening, gas utility
meter, service regulator etc.
• Enclose exterior vent systems below
the roof line to limit condensation and
protect against mechanical failure.
• When the vent penetrates a floor or
ceiling and is not
running in a fire rated shaft, a firestop
and support is required.
• Terminate the vent system at least
0.6m (2') above, but not more than
1.8m (6') above the roof line, or
according to the vent pipe
manufacturer's instructions.
• Provide vertical support every 3.7m
(12') or as required by the vent pipe
manufacturer's instructions.
• Slope the horizontal vent 1/4" down-
wards for every 305mm (12").
• Do not vent straight upwards. Always
have a horizontal section of venting.
• Install a condensation drain in the
horizontal section of the venting.
