Danger
Opening the boiler connections
and openings whilst the boiler
is under pressure can lead to a
high risk of severe injury.
Only open the connections on
the water side after the boiler
has been fully depressurised.
Note
Install all pipe connections free of
load and torque stresses.
1. Thoroughly flush the system (espe-
cially when connecting the boiler to
an existing system).
2. Make all necessary line connec-
tions.

the operating pressure of the boiler
and that is suitable for the intended
operating mode (operation with or
without constant supervision). Agree
details with the responsible approval
body that should also approve them.
Note
Carry out the installation in accor-
dance with the instructions supplied
with the devices.
