Draining hot water

The blow-down and TDS water from boiler sys-
tems can reach temperatures of over 100 °C.
Before draining water into the sewage system,
allow it to cool to a temperature of < 35 °C. If
necessary, consult the local water board.
Draining condensate from the flue gas side
!
Please note
When starting up the boiler system, or under
certain operating conditions, condensate may
build up in the flue passes, the flue gas collector
and the downstream flues, including the chim-
ney.
The condensate must be drained away safely by
means of suitable installation measures put in
place by the system installer.
Subject to the regulations in the country concerned,
this condensate may need to be neutralised. In such
cases, consult the local water board or the body
responsible for issuing permits.
After an accident, the condition of the system must not
be changed before the investigation takes place,
unless necessary in order to rescue people or prevent
further damage.
