Burner start-up
Feed electricity to the burner via the disconnecting switch on the
boiler panel.
Close
the
thermostats/pressure
switch 4)(Fig. 8 on page 13) to position "(1) - ON".
Check that the lamps or testers connected to the
solenoid valves, or the pilot lights on the solenoid
valves, indicate that no voltage is present.
DANGER
If they indicate the presence of voltage, stop the
burner immediately and check the electric
connections.
As the burner is not fitted with a device to check the sequence of
the phases, the rotation of the motor may be incorrect.
As soon as the burner starts place yourself in front of the cooling
fan of the fan motor and check that it turns anticlockwise. See
Fig. 33.
If this is not the case:
–
set the switch 4)(Fig. 8 on page 13) to "(0) - OFF" and wait
until the flame control carries out the switching off phase;
–
disconnect the burner form the power supply;
–
invert the phases on the three-phase power supply.
