Faults / Solutions
Possible cause
Lack of electrical supply.
The flame sensor sees false light.
The connections in the control box
are wrongly inserted.
The heater is faulty or the P short-cir-
cuit socket is not connected (if there
is not a heater).
The flame sensor sees extraneous
light.
The flame sensor is dirty.
The flame sensor is faulty.
Flame moves away or fails.
The ignition electrodes are wrongly
positioned.
Air output is too high.
Nozzle dirty or worn.
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.
