Connecting the condensate water drain
No condensate water drain is integrated into the appli-
ance. It is necessary to install the furnished 3” x ¾” drain
tee as an external condensate water drain. See fig. 21.
Install this drain tee as close as possible to the appliance
exhaust connection.
If the condensate outlet of the appliance is lower than
the drain, a condensate pump must be used.
The condensate produced by the appliance has a pH
value between 3 and 4.
Install a neutralization unit if required by the local code.
NOTICE
The condensate water must be drained from
the appliance and possibly from the flue in
accordance with the applicable rules.
Observe the local regulations.
