6. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for 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 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 damage to the installation. On
