Burner start-up
Feed electricity to the burner via the disconnecting switch on the
boiler panel.
Close the thermostats/pressure switches, set the parameters on
the RWF 40 regulator. Please refer to the spacific manual for this
operation. Turn the switch of Fig. 37 to position "ON" and turn the
switch of Fig. 37 to position "LOCAL".
Make sure that the lamps or testers connected to
the solenoids, or indicator lights on the solenoids
themselves, show that no voltage is present. If volt-
age is present, stop the burner immediately and
DANGER
check the electrical wiring. When the burner starts,
check the direction of the motor rotation, as indi-
cated in (Fig. 37).
As the burner is not fitted with a device to check the
sequence of the phases, the motor rotation may be
incorrect. As soon as the burner starts up, go in front
of the cooling fan of the fan motor and check it is
rotating anticlockwise. See Fig. 37.
If this is not the case:
place the switch of Fig. 37 in position "0" and
wait for the control box to carry out the switch-
off phase;
disconnect the electrical supply from the
burner;
invert the phases on the inverter output.
For further information, please refer to the specific
instruction of the control box.
