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 button of the control box.
When lockout lamp comes on the burner will attempt to light only
after pushing the reset button. After this if the burner functions
correctly, the lockout can be attributed to a temporary fault that is
not dangerous.
If however the lockout continues the cause must be determined
and the solution found.
