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 operator panel display shows the lockout code.
When the burner starts up again, the red LED goes out.
In the event the burner stops, in order to prevent
any damage to the installation, do not unblock the
burner more than twice in a row.

If the burner locks out for a third time, contact the
customer service.
