9 Set the atomising air pressure switch PA (Fig. 21) at 0.5 bar
10 Set the pilot gas pressure switch PG (Fig. 22) at 50 mbar.
11 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); read the pressure on the oil pressure gauge on Fig. 25 and act on on the Suntec TV governor adju-
sting screw
VR (see Fig. 24 and description on page 23) as to get the nozzle pressure at 2bar (see step 8). If the required flow rate
is not reached, increase the feeding pressure by means of the Suntec TV governor (see picture below)
12 in order to get the maximum oil flow rate, adjust the pressure (reading its value on the oil pressure gauge (Fig. 25): checking always the
combustion parameters, the adjustment is to be performed by means of the SV adjusting cam screw V (Fig. 26) when the cam has rea-
ched the high flame position.
