5.3 Condensate connection
DANGER
Danger of poisoning by escaping flue gas
Inhalation leads to dizziness, nausea and eventually death.
▶
Check the fill level of the siphon at regular intervals and replenish, if necessary, in
particular when the system has been shut down for longer periods or has been
operated at high return temperatures (> 55 °C).
The condensate generated during the heating operation is discharged to the house
waste water drainage system via an integrated siphon.
Observe work sheet ATV-DVWK-A 251 and install a neutralisation system if required.
If the discharge point of the waste water system is located above the condensate
drain:
▶
Installing condensate lift pump.
Filling the siphon
▶
Run condensate hose on siphon to condensate outlet pipe.
▶
Fill siphon with water via the flue gas outlet of the boiler, until water flows from the
condensate hose.
If an external siphon
1
is present external to the boiler (e. g. due to the condensate
hose):
▶
Cut of cap from ventilation opening.
If there is no external siphon present, the cap must not be removed.
