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
(4, fig. 1, page 2).
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 opera-
tions could cause damage to the installa-

tion. On the third lockout, contact the
Aftersales Service.
