Vertical Vent Termination
• Terminate at least 6' from the combustion air
intake of any appliance, and 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 2' above,
but not more than 6' above the roof line, or
according to the vent pipe manufacturer's
instructions.
• Provide vertical support every 12' or as re-
quired by the vent pipe manufacturer's instruc-
tions.
• Slope the horizontal vent 1/4" downwards for
every 12".
• Do not vent straight upwards. Always have a
horizontal section of venting.
• Install a condensation drain in the horizontal
section of the venting.

• 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.
