6. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for some problems that could cause a failure
to start or a bad working of the burner.
A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box (7,
fig. 1, page 1).
When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if the
burner functions correctly, the lock-out can be attributed to a temporary fault.
If however the lock out continues the cause must be determined and the solution found.
In the event of a burner lockout, more than two consecutive 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, interventions must only be made by qualified, authorised per-
sonnel (as indicated in this manual, and in compliance with the laws and regulations currently in force).
