- Page 8 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 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 Fig. 10 Burners PG25SP - PG30TN Loose the screw VBS and set the air flow, working directly on the air damper. - Page 11 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. THE USER MUST GUARANTEE THE CORRECT FITTING OF THE APPLIANCE, ENTRUSTING THE INSTALLATION OF IT TO QUALIFIED PERSONNEL AND HAVING THE FIRST COMMISSIONING OF IT CARRIED OUT BY A SERVICE CENTRE AUTHORISED BY THE COMPANY MANUFACTURING THE BURNER.

- Page 21 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.
