Start-up, calibration and operation of the burner

5.1

Notes on safety for the first start-up

The first start-up of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
WARNING tions of the laws in force.
5.2

Operations before start-up

 Ensure that the gas supply company has carried out the sup-
ply line vent operations, eliminating air or inert gases from the
piping.
 Slowly open the manual valves situated upstream of the gas
train.
 Adjust the minimum gas pressure (Fig. 37) switch to the start
of the scale.
 Adjust the maximum gas pressure switch (Fig. 36) to the end
of the scale.
 Adjust the air pressure switch (Fig. 34) to the start of the scale.
 Purge the air from the gas line.
Fit a U-type manometer (Fig. 32) to the gas pressure test point
on the sleeve. The manometer readings are used to calculate
the MAX. burner power using the diagram on page 23.
Before starting up the burner it is good practice to adjust the gas
train so that ignition takes place in conditions of maximum safety,
i.e. with gas delivery at the minimum.

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. 33 to position "ON" and turn the switch of
Fig. 33 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-
DANGER age is present, stop the burner immediately and
check the electrical wiring. When the burner starts,
check the direction of the motor rotation, as indicat-
ed in Fig. 33.
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 ro-
tating anticlockwise. See Fig. 33.
If this is not the case:
 place the switch of Fig. 33 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.
Start-up, calibration and operation of the burner
Check the correct working of the adjustment, com-
mand and safety devices.
