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 55 regulator. Please refer to the spacific manual for this
operation.
Turn the switch to position "ON" (Fig. 31) and turn the switch of to
position "LOCAL" and turn the switch to position "OIL" for oil oper-
ation and "GAS" for gas operation.
Make sure that the lamps or testers connected to
the solenoids, or indicator lights on the solenoids
themselves, show that no voltage is present.
DANGER
If voltage is present, stop the burner immediately
and check the electrical wiring.
When the burner starts, check the direction of the
motor rotation, as indicated in Fig. 31.
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.
If this is not the case:
➤ place the switch 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 three-phase power
supply.
