Operating faults

 

Tab. R

The burner locks out during the
pre-purge phase.

The air pressure switch does not change over
to the operational position.

The pressure switch is faulty, change it.
The air pressure is too low, (the head is bad adjust-
ed).

The flame exists.

Faulty valves: replace them.

The  burner  continues  to  re-
peat the starting cycle without
going on lockout.

The  gas  pressure  in  the  gas-mains  lies  very
close  to  the  value  to  which  the  gas  pressure
switch has been set. 
The sudden drop in pressure when the valve is
opened provokes the opening of the pressure
switch itself, so the valve closes again immedi-
ately and the motor stops. 
The pressure then starts to increase again, the
pressure switch closes, the start-up cycle be-
gins again and so on.

Lower and set the pressure switch.

Fault

Possible Causes

Solution

The burner locks out during op-
eration.

Earth probe.

Check the right position and if necessary set it ac-
cording to the instructions of this manual.
Clean or replace the ionisation probe.

The flame disappears 4 times.

Check the gas pressure in the network and/or ad-
just  the  solenoid  valve  according  to  the  instruc-
tions of this manual.

Air pressure switch opening.

The air pressure is too low, (the head is bad adjust-
ed).
The air pressure switch is faulty: change it.

Burner shut down.

Gas pressure switch opening.

Check  the  pressure  in  the  network  and/or  adjust
the solenoid valve according to the instructions of
this manual.
