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 relative
diagnostic. To reset the start-up conditions, refer to the "Reset pro-
cedure" indicated in the control box manual supplied.
When the burner starts again, the red LED goes out and the control
box is reset.
In the event of a burner lockout, more than two con-
secutive burner reset operations could cause dam-
age 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 com-
pliance with the laws and regulations currently in
DANGER
force).
