UPOZORENJE
External power output should only be used for optional
parts supplied by manufacturer,
instructions provided within the manual of optional parts.
Failure to observe this warning will void the warranty. The
manufacturer is not responsible for any damage that may
occur this way.
4.8.7 Guidelines when connecting the
condensate piping
OPASNOST
In order to prevent escape of flue gases and so poisoning,
the condensate trap must be mounted to its place before
commissioning.
Condensate trap must be connected to a drain via an open
connection.
Precautions that should be taken about condensate piping are:
▪ Horizontal pipe runs must fall a minimum of 45 mm/metre.
▪ External piping should be kept as short as possible or thermally
insulated to prevent freezing, depending on the installation winter
climate condition.
▪ Make sure that the condensate disposal system, the piping, and
the fittings are made of acid resistant material like plastics.

according to the
UPOZORENJE
The condensate trap outlet shall not be modified or
blocked.
OPREZ
The condensate discharge piping diameter must be large
enough so as not to restrain the condensate water flow.
UPOZORENJE
If the discharge pipe is located outdoors, take measures
against frost.
4.8.8 Guidelines for condensate piping
termination
Condensate piping can be connected to a termination in different
ways shown below:
Terminating into an internal soil and vent stack
