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. 
In most cases, an operation irregularity leads to the lighting up of
the signal inside the reset button of the control box (1, Fig. 2,
page 7
). 

When this lamp lights on, the burner will attempt to operate only
after pressing the reset button. 
After this, if the burner functions correctly, the lockout can be at-
tributed to a temporary fault. 
If however the lock out continues the cause must be determined
and the solution found.

Faults

Possible causes

Solution

The burner does not start when the
limit thermostat closes.

Lack of electrical supply.

Check presence of voltage in the L1-N clamps of
the 7 pin plug.
Check the conditions of the fuses.
Check that safety thermostat is not lock out.

Lack of gas.

Check the manual cock opening.
Check that valve has changed over to open posi-
tion and that there are no short circuits.

The connections in the control box
are wrongly inserted.

Check and connect completely all the plugs.

Burner runs normally in pre-purging
and ignition cycle and locks out after
3 firing attempts.

The phase-neutral connection is in-
verted

Invert them.

The earth connection lacks or is inef-
ficient.

Make the earth connection efficient.

Valve lets too little gas through

Check mains pressure and/or adjust the valve as
indicated in this manual.

The gas valve is faulty.

Replace.

The electric ignition arc is irregular.

Check the right insertion of the connectors.
Check the right position of the electrode according
to the instructions of this manual.
Inspect the quality of the ceramic insulator.

The ionisation 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.

Check right position and, if necessary, adjust as in-
dicated herein.
Reset the electrical connection.
Replace the faulty connection.

Lack of gas.

Check the manual cock opening.
Check that valve has changed over to open posi-
tion and that there are no short circuits.

Burner starts with an ignition delay.

The ignition electrodes is wrongly
positioned.

Adjust it according to the instructions of this manu-
al.

Air output is too high.

Set the air output.

Valve brake not open enough, with
insufficient gas allowed through.

Adjust it.

The burner locks out during the pre-
purge phase.

The flame exists.

Faulty valve: change it.
