and check the electrical connections.
As the burner is not fitted with a device to check the sequence of
the phases, it may be that the rotation of the motor is incorrect.
As soon as the burner starts up, go in front of fan motor cooling
fan and check it is rotating anticlockwise or else in the direction
of the arrow shown in the diagram Fig. 4 on page 11.
If this is not the case:
– put the switch of Fig. 27 to "0/OFF" and wait until the flame
control carries out the switching off phase;
– disconnect the burner form the electrical supply.
Invert the phases on the three-phase power sup-
ply. This operation must be carried out with the
electrical supply disconnected. Follow the "Start-
up procedure" on page 40.
