Instructions for the user
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.
In this case, contact a Service Centre or a qualified service engineer to carry out the maintenance.
1.4.4
Shut-down due to low water pressure
Fault code E04 is displayed on the LCD display in the event of shut-down triggered by the water pressure switch.
Fill the system by working on filler cock (A) (see Fig. 2 Filler cock).
Water pressure must be 1÷1.3 bars while the boiler is cold.
In order to restore water pressure, proceed as follows:
• Turn the filler cock anticlockwise to allow water to enter the boiler;
• Keep the filler cock open until the pressure gauge shows a value of 1÷1.3 bar;
• Turn cock clockwise to close it.
Should boiler shuts down frequently occur it means there is boiler malfunction in progress. Contact qualified personnel or an authorised
service centre for maintenance.
DANGER
Make sure you close filler cock (A) carefully after filling procedure is completed.
If you do not, when the pressure increases, the safety valve may activate and discharge water.
