1.4 Boiler shut-down
The boiler shuts down automatically if a malfunction occurs.
To determine the possible causes of malfunction (see
Troubleshooting
on page
44
).
Below is a list of shut-down types and the procedure to follow in each case.
1.4.1
Burner shut-down
Fault code E01 is displayed flashing on the display in the event of burner shut-down due to missing flame.
If this happens, proceed as follows:
• check that the gas cock is open and light a kitchen gas ring for example to check the gas supply;
• once having checked if the fuel is available, press the Reset button to restore burner operation: if, after two starting attempts, the boiler still
fails to start and enters the shut-down mode again, contact a service centre or qualified personnel for maintenance.
WARNING
If the burner shuts down frequently, there is a recurring malfunction, so contact a service centre or a qualified service engineer.
1.4.2
Shut-down due to overheating
Fault code E02 is shown on the LCD display in the event of flow water temperature overheating. Contact a service centre or a qualified service
engineer to carry out the maintenance.
1.4.3
Shut-down due to incorrect air/flue gas system draught
The boiler is equipped with a safety device for flue gas exhaustion check.
Should an air/flue gas system malfunction occur, the control device will shut-down the boiler by interrupting the gas supply to the boiler and
the LCD will display the E03 code.
To resume the operation press Reset (see Fig. 1 Control panel on page
8
).
In case of repeated stops, it is necessary to have the boiler and the air intake/flue gas venting ducts checked by a service centre or a qualified
service engineer.
