FAULTS
The burner runs nor-
mally in the prepurge
and ignition cycle and
locks out after about 3
seconds.
The burner starts with
an ignition delay.
The burner locks out
after the prepurge
phase due to flame-
failure.
The burner locks out
during the prepurge
phase.
The burner continues
to repeat the starting
cycle without going on
lock-out.

POSSIBLE CAUSES
Phase and neutral connection is in-
verted.
The earth connection lacks or is in-
efficient.
The ionization probe is earthed or not
in contact with the flame, or its wiring
to the control box is broken, or there
is a fault on its insulation to the earth.
The ignition electrodes is wrongly
positioned.
Air output is too high.
Valve brake is too close with insuffi-
cient gas output.
The solenoid valves is passing too
little gas.
The solenoid valves are defective.
The ignition arc is irregular or has
failed.
The pipe has not been purged from
the air.
The air pressure switch does not
change over to the operational posi-
tion.
The flame exists.
The gas pressure in the gas-mains
lies very close to the value to which
the gas pressure switch has been set.
The sudden falling-off pressure at the
opening of the valve causes the
opening of the pressure switch.
However this only temporarily, be-
cause the valve immediately closes
again, so then does the pressure
switch, because the pressure builds-
up again, causing the cycle to be
repeated over and over.
Invert them.
Make the earth connection efficient.
Check the right position and if neces-
sary set it according to the instructions
of this manual.
Reset the electrical connection.
Replace the faulty connection.
Adjust it according to the instructions
of this manual.
Set the air output according to the in-
structions of this manual.
Adjust it.
Check the pressure in the network and/
or adjust the solenoid valve according to
the instructions of this manual.
Change them
Check the right insertion of the connec-
tors.
Check the right position of the electrode
according to the instructions of this man-
ual.
Carry out a complete breathing of the
line of gas-supply.
The pressure switch is faulty, change it.
The air pressure is too low, (the head is
bad adjusted).
Faulty valves: replace them.
Lower and set the pressure switch.
