) GENERAL INSTRUCTIONS DEPENDING ON FUEL USED 3B) FIRING WITH GAS, GASOIL OR OTHER FUELS 3A) ELECTRICAL CONNECTION GENERAL * For safety reasons the unit must be efficiently earthed and installed as required by current safety regulations. * It is vital that all saftey requirements are met. In case of any doubt, ask for an accurate inspection of electrics by qualified personnel, since the manufacturer cannot be held liable for damages that may be caused by failure to correctly earth the equipment.

MOUNTINGS AND CONNECTIONS The burners are despatched in cardboard packages. The packaging contains the following items: 1 burner; 2 flexible light oil tubes; 1 light oil filter; 1 gasket to be inserted between the burner and the boiler; 1 this manual, the Guarantee Certificate and the test certificate. To get rid of the burner’s packing and in the event of scrapping of the latter, follow the procedures laid down by current laws on disposal of materials.

SETTINGS Burners G18SP - PG25SP These burners are fitted with a double-regulation pump. The flame control device, a twin-stage one, after the pre-purgue stage, energized the valve EV1 and the burner starts up. After few seconds, the intervention of the second stage caused the energizing of the valve EV2, so the burner is feeded with a maximum pressure of about 18 bar.

AIR FLOW ADJUSTMENT VBS + Burner G18SP Loose the screw VBS and rotate the air damper in the desired position, to set the air flow. At the end of settings, tight the screw VBS. Fig. 10 Burners PG25SP - PG30TN Loose the screw VBS and set the air flow, working directly on the air damper. At the end of settings, tight the screw VBS. Fig. 11 VBS COMBUSTION HEAD ADJUSTMENT The burner is factory-adjusted with the combustion head in the “max” position (maximum output).
PART II: OPERATION MANUAL LIMITATIONS OF USE THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY CONNECTED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO BE CONSIDERED IMPROPER AND THEREFORE DANGEROUS.
PART III: MAINTENANCE At least once a year carry out the following maintenance procedures. If servicing is on a seasonal basis, it is recommended at the end of the season; routine sevice should be carried out every months. Note: Any operation on the burner must be carried out with the main electricity switched off.
CHECK OF THE IONIZATION CURRENT To check the detector signal follow the prcedure shown in fig. 14. If the signal is not within the prescribed range, check the electrical contacts; check also that the combustion head is clean and the photoelectric sensor is correctly positioned. Replace it if necessary. TERMINAL BLOCK MC Scale µA DC Minimum current .7067 ( witt )Tj/TT3 1 Tf52.9337 (-0.0101 Tc-0.0061 Tw[flame:)-6187.8(65e Fig. 14 µT)]TJ -10 -1523 TD-0.0002 Tc-0.

Operation The gear-set draws oil from the tank through the built-in filter and transfers it to the valve that regulates the oil pressure or tne nozzle line. All oil which does not go through the nozzle line will be dumped through the valve back to the return line or, if it is a one-pipe installation, back to the suction port in the gear-set. The hydraulic valve has a cut-off function besides regulating the nozzle pressure. Contrary to the AN pump, the valve has no bleed slot.
