DANGER
Danger of poisoning by escaping flue gas
Flue gas can escape if the siphon is not filled. 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
sewage system via an integrated siphon.
Observe work sheet DWA-A 251 and local regulations, if required, fit a neutralisa-
tion system.
If it is necessary to raise the condensate drain, a appliance foot extension kit (ac-
cessory) can be installed.
If the discharge point of the sewage system is above the condensate outlet:
Installing condensate lift pump.
