Condensate - Weishaupt thermo condens WTC 15-A Installation And Operating Instructions Manual

4.8 Condensate

Condensate discharge into the waste water system
The condensate of the WTC complies with the
requirements as stipulated in the ATV data sheet A 251for
condensate discharge into the waste water system of the
property. Neutralisation is usually not required.
If necessary, the water board should be informed about the
discharge.
If the boiler is mainly operated in the non-condensing
range, the internal siphon must always be filled with water.
If the siphon is empty, flue gas can escape.
Fill siphon with water - top up if flue gas can be
smelled.
Note: When installing the siphon ensure that the
condensate is expelled completely, as a blockage
in the condensate line will cause operational
problems. Therefore do not connect the
condensate hose permanently to the waste pipe,
but mount it free-flowing (e.g. into an
outlet hopper).
If the siphon is empty, flue gas will escape into
the boiler room. During prolonged shutdown
or if operating the installation with high return
flow temperatures ( > 55°C ) the water level of
DANGER
the siphon should be checked.
