Regions of cold climate will create
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 be used
in horizontal terminations if a vertical rise
in the vent system exceeds 5ft.
WARNING
If the condensate collector is not used, the drain pipe
must be capped to prevent exhaust gases and
condensate from entering the building. The cap is
supplied on the appliance.
