MAINTENANCE
8.1
General
The boiler does not require complex maintenance. It is advisable, however, to have it inspected and serviced on a regular basis.
Servicing and cleaning of the boiler must be carried out a minimum of once a year by a qualified professional.
8.2
Maintenance message
By displaying the
symbol, this function warns the user that the boiler requires maintenance (if the function is enabled, refer to
the installation manual).
8.3
Maintenance notes
Periodically check that the pressure displayed on the pressure gauge is 1 - 1.5 bar, with the system cold. If it is lower, turn the
system filling tap installed as instructed in section "Filling the installation". It is advisable to open the tap very slowly in order to
vent the air.
The boiler is fitted with a hydraulic pressure switch which prevents the boiler from working if there is no water.
If pressure drops occur frequently (monthy basis), have the system checked by the Authorised technical service agent.
8.4
Filling the installation
The filling knob is light blue and located under the boiler, as shown in the
picture to the side. To fill the system, proceed as follows:
• Pull the knob (A) downwards to release it from its seat.
• Slowly turn the knob anticlockwise (to the left) to fill the system. Do this by
hand without using any tools.
• Fill the system until the reading on the pressure gauge (B) is between 1.0
and 1.5 bar.
• Close the tap and check that no water leaks out.
Periodically check the reading on the pressure gauge (B) when the system is
cold. If the pressure is low, turn the valve to increase it again.
