Do not change the position of the air damper rods. 11 The burner is factory-set with the head in its MAX position (maximum output). To let the burner operate at a lower output, turn clockwise the VRT screw and move progressively the combustion head back towards the MIN position.
  • Page 31 Calibration of air and gas pressure switches The air pressure switch locks the control box if the air pressure is not the one requested. If it happens, unlock the burner by means of the control box unlock pushbutton, placed on the burner control panel. The gas pressure switches check the pressure to avoid the burner operate when the pressure value is not in the requested pressure range.
  • Page 32 Fully modulating burners To adjust the fully-modulating burners, use the CMF switch on the burner control panel (see next picture), instead of the TAB thermo- stat as described on the previous paragraphs about the progressive burners. Go on adjusting the burner as described before, paying attention to use the CMF switch intead of TAB.
  • Page 33 Adjustment procedure for light oil operation The light oil flow rate can be adjusted choosing a by-pass nozzle that suits the boiler/utilisation output and setting the delivery and return pressure values according to the ones quoted on the table below and the diagram on Fig. 25 (as far as reading the pressure values, see next paragraphs).
  • Page 34 Fig. 25 Example (Bergonzo): if a 220kg/h flow rate BERGONZO nozzle is provided, set the return pressure at 11bar, supply at 20bar on the delivery to get a 220kg/h flow rate. If the return pressure needed is 5bar, instead, act on the V adjusting screw on the pressure governor (see chapter on page 33).
  • Page 35 Fig. 26 Example (Bergonzo): if a 140kg/h flow rate BERGONZO 45° nozzle is provided, set the return pressure at 13bar, supply at 20bar on the delivery to get a 110kg/h flow rate. If the return pressure needed is 5bar, instead, act on the adjusting screw on the pressure gover- nor.

Pressure gauge port Fig. 29 Fig. 30 10 in order to get the maximum oil flow rate, adjust the pressure (reading its value on the PG pressure gauge) without changing the air flow rate set during the gas operation adjustments (see previous paragraph): checking always the combustion parameters, the adjustment is to be performed by means of the SV2 adjusting cam screw (see picture) when the cam has reached the high flame position.
  • Page 43 Maximum oil pressure switch The oil pressure switch on the return line, checks that the pressure does not exceed a default value. This value must not be higher than the maximum acceptable pressure on the return line (this value is reported on the specification table). A pressure change on the return line could affect the combustion parameters: for this reason, the pressure switch must be set, say, at 20% over the pressure recorded during the combustion adjustment.
  • Page 44 Oil circuit The fuel is pushed into the pump 1 to the nozzle 3 at the delivery pressure set by the pressure governor. The solenoid valve 2 stops the fuel immission into the combustion chamber. The fuel flow rate that is not burnt goes back to the tank through the return circuit. The spill-back nozzle is feeded at constant pressure, while the return line pressure is adjusted by means of the pressure governor controlled by an actuator coupled to an adjusting cam.
  • Page 45 PART II: OPERATION LIMITATIONS OF USE THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY CONNEC- TED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO BE CONSIDE- RED IMPROPER AND THEREFORE DANGEROUS.
  • Page 46 Few seconds after the gas valves opening, the transformer is de-energised and lamp L turns off. The burner is now operating, meanwhile the actuator goes to the high flame position and, after some seconds, the two-stage ope- ration begins; the burner is driven automatically to high flame or low flame, according to the plant requirements. Operation in high or low flame is signalled by lamp N on the frontal panel.
