Installing the Water Heater
3.5.4 Terminating the Vent
Before installing the water heater, determine what
type of vent termination is appropriate for the
installation location and situation. Examples in this
section describe typical venting configurations, but
they do not include all possible options.
The following installation guidelines can be used.
Refer to the vent manufacturer’s instructions for
detailed installation procedures.
Horizontal Termination
Regions with cold climates will produce more
condensate in the vent system. The condensate
collector should be used in cold climates. If more
than one elbow is used in the vertical section, the
condensate collector must be used. The condensate
collector must also be used in horizontal
terminations if a vertical rise in the vent system
exceeds 5 ft. Slope the vent
