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.
A fault usually makes the lockout led signal which is situated in-
side the reset push-button of the control box.
When the lockout lamp comes on, the burner will only attempt to
start up after the reset push-button has been pressed. If ignition
is then normal, the stop can be attributed to a temporary fault that
is not dangerous.
If however the lock out continues the cause must be determined
and the solution found.
