Faults - Possible causes - Solutions
If faults arise in ignition or operations, the burner performs a
"safety stop", which is signalled by the red burner lockout LED.
The display visualises alternately the lockout code and the rela-
tive diagnostic. To reset the start-up conditions, refer to the "Re-
set procedure" indicated in the control box manual supplied.
When the burner starts again, the red LED goes out and the con-
trol box is reset.
In the event of a burner lockout, more than two
consecutive burner reset operations could cause
damage to the installation. On the third lockout,
contact the Aftersales Service.
WARNING
If further lockouts or burner faults occur, interven-
tions must only be made by qualified, authorised
personnel (as indicated in this manual, and in
compliance with the laws and regulations current-

ly in force).
