Refer to the appliance manufacturer for
the maximum and minimum allowed vent
runs for your specific appliance model,
including maximum number elbows allowed
in the system, and for the pressure drops
and equivalent length of the fittings. The
total vent length from the appliance to the
termination shall not be greater than what is
specified by the appliance manufacturer.
plan the layout of the vent system:
Consider the length of horizontal runs,
elbows, clearance requirements, and location
of terminations.
For horizontal vent runs, always maintain
at least a ¼” rise per foot (20mm rise per
1m) away from the appliance to prevent
collection of condensate or buildup of heat
in the vent.
Consider condensate drainage. Refer to
the appliance manufacturer’s installation
instructions for requirements of condensate
drainage.
Normal operation of gas burning appliances
does not result in deposits of combustible
soot in venting systems. However, a poorly
adjusted or malfunctioning appliance
can deposit soot and other debris which
can enter the vent system. Any such
accumulation should be removed and the
appliances adjusted to eliminate future
accumulation. Use only a soft brush for
cleaning the sections and fittings. If any

leakage is found at joints the connected
appliances should be turned off and the
leaks repaired. A venting system must
not be routed into, through, or within any
other vent, such as an existing masonry or
factory-built chimney flue, unless that vent
or chimney is not being used to vent another
appliance and is only used as a conduit for
the gas-vent system.
Plastic venting systems shall not pass
through fire rated separations.
