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 in-
side the reset button of the control box. When lock out lamp lights the burner will attempt to light only after
pushing the reset button. After this if the burner functions correct-
ly, 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.
