9 The nozzle supply pressure is already factory-set and must not be changed. Only if necessary, adjust the supply pressure as fol-
lows (see related paragraph);insert a pressure gauge into the port shown on Fig. 12 and act on on the pump adjusting screw
VR
(see Fig. 11 and page 12) as to get the nozzle pressure at 25bar (Fluidics/Bergonzo nozzles - see diagram on page 23).
10 In order to get the maximum oil flow rate, adjust the pressure (reading its value on the PG pressure gauge (see picture above):
always checking the combustion parameters, the adjustment is to be performed by means of the SV adjusting cam screw (see pic-
ture above) when the cam has reached the high flame position.
11 To adjust the air flow rate in the high flame stage , loose the RA nut and screw VRA as to get the desired air flow rate: moving
the rod TR towards the air damper shaft, the air damper opens and consequently the air flow rate increases, moving it far from the
shaft the air damper closes and the air flow rate decreases.
Note: once the procedure is perfomed, be sure that the blocking nut RA is fasten. Do not change the position of the air damper
rods.
Only if necessary, change the combusiton head position: to let the burner operate at a lower output, loose the VB screw and move pro-
gressively back the combustion head towards the MIN position, by turning clockwise the VRT ring nut. Fasten VB screw when the
