The boiler does not require a lot of maintenance. Nevertheless, we
recommend having the boiler inspected and serviced at regular
intervals.
4 Maintenance and cleaning of the boiler must be carried out at least
once a year by a qualified technician.
4 Have the flues swept at least once a year or more, depending on
the regulations in force in your country.
CAUTION
Maintenance operations must be done by a qualified
4
engineer.
We recommend taking out a maintenance contract.
4
Only original spare parts must be used.
4
The boiler displays a message whenever maintenance is necessary.
1. When the message, REVISION, is displayed, press ? to display
the installer's telephone number.
2. Contact the fitter.
3. Have the required checks and services done.
4 Check the water pressure in the installation.
If the water pressure is lower than 0,8 bar, more water
should be added. If necessary, top up the water level in the
heating system (recommended hydraulic pressure
between 1,5 and 2,0 bar).
¼ See chapter: "Filling the system", page 26.
4 Carry out a visual check for the presence of any water leaks.
