Faults / Solutions
Here below you can find some causes and the possible solutions
for some problems that could cause a failure to start or incorrect
operation of the burner.

after pushing the reset button. After this if the burner functions
correctly, the lockout can be attributed to a temporary fault that is
not dangerous.
Otherwise, if the lockout persists the cause of the fault should be
sought and the solutions shown in Tab. Q put into effect.
