Installation
4.6 Choice of nozzle
Nozzles with no fuel shutoff needle must be fitted on the nozzle
holder.
To set the delivery range within which the nozzle must work,
nozzle return line fuel pressure must be adjusted according to
the table (Tab. 5-Tab. 6).
Tab. 5
Tab. 6
Recommended nozzle
• BERGONZO, type B5 45°;
• FLUIDICS, type N4 45°.
Intermediate flow rates may be obtained by choosing the nozzle
with a nominal flow rate slightly higher than that actually re-
quired.
Complete range of nozzles:

Bergonzo type B5 45° (Tab. 5):
350 - 375 - 400 - 425 - 450 - 475 - 500 - 525 - 550 - 575 - 600 -
650 - 700 - 750. We normally recommend 45° angles of pulver-
isation.
 Fluidics type N4 45° (Tab. 6):
375 - 400 - 450 - 500 - 550 - 600 - 650 - 700 - 750. We normally
recommend 45° angles of pulverisation.
Fit the nozzle with the box spanner, fitting the spanner through
the central hole in the flame stability disk.
Do not use any sealing products such as gaskets, sealing com-
pound, or tape. Be careful to avoid damaging the nozzle sealing
seat. The nozzles must be screwed into place tightly but not to
the maximum torque value provided by the wrench.
4.7 Electrode positioning
Place the electrode on the ignition pilot observing the
dimensions specified in Fig. 13.
