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.
In most cases, an operation irregularity leads to the lighting up of
the signal inside the reset button of the control box 1)(Fig. 3, on
page 11).

pushing the reset button If ignition is then normal, the lockout can
be attributed to a temporary fault.
However, if lockout continues, you must determine the cause of
the problem and take the action illustrated in the tables below.
