4. Check the tightness of the water connections.
After switching on the power and if there is adequate water
pressure, the boiler always runs through an automatic
venting program lasting approximately 3 minutes (During
filling, air can escape from the system via the automatic air
vent). If the water pressure is lower than 0,8 bar, the symbol
e
will appear. If necessary, top up the water level in the
heating system (recommended hydraulic pressure
between 1.5 and 2 bar).
CAUTION
4
The filling must be carried out within 30 minutes,
otherwise the venting program starts and that would
be undesirable if the device is not filled. Switch off the
boiler if the central heating system is not being
topped up immediately.
4
When venting, prevent water from getting into the
boiler casing and electrical parts of the boiler
