3.3 Troubleshooting

The burner is equipped with an advanced self-diagnosis system. In case of a burner fault, the display (detail 4 - fig. 1)
flashes indicating the fault code.
There are faults the cause permanent shutdowns (marked with the letter "A"): to reinstate operation, press the "Reset"
button (detail 8 - fig. 1) for 1 second; if the burner fails to restart, it is necessary to firstly eliminate the fault.
Other faults cause temporary shutdowns (marked with the letter "F") which are automatically reset as soon as the value
returns within the burner's normal operating range.
