PART I: INSTALLATION GENERAL FEATURES This series represents monobloc gas burners made in die-cast aluminium housing, the combustion head position can be adjuste- dwhich allows a good performance. Fig. 1 Gas valve group Blast tube-Combustion head ass.y Burner flange Burner cover The fuel coming from the supply line, is pushed by the pump to the nozzle and then into the combustion chamber, where the mixture between fuel and air takes place and consequently the flame. - Page 6 Campo di lavoro bruciatori Tipo P60 Mod. M-xx.x.IT.A.0.50 - M-.xx.x.IT.A.0.65 Potenza kW Fig. 2 Data are referred to standard conditions: atmospheric pressure at 1013mbar, ambient temperature at 15°C Matching the burner to the boiler The burners described in this manual have been tested with combustion chambers that comply with EN676 regulation and whose dimensions are described in the diagram .

From tank To tank Fig. 7 - Double-pipe system The burner is supplied with filter and flexible hoses, all the parts upstream the filter and downstream the return flexible hose, must be installed by the customer.
- Page 12 Bleed Bleeding in two-pipe operation is automatic : it is assured by a bleed flat on the piston. In one-pipe operation, the plug of a pressure gauge port must be loosened until the air is evacuated from the system. About the use of fuel pumps Make sure that the by-pass plug is not used in a single pipe installation, because the fuel unit will not function properly and damage ...

Page 14: Electrical Connections
Electrical connections Respect the basic safety rules. make sure of the connection to the earthing system. do not reverse the phase and neutral connections. fit a differential thermal magnet switch adequate for connection to the mains. ATTENTION: before executing the electrical connections, pay attention to turn the plant’s switch to OFF and be sure that the burner’s main switch is in 0 position (OFF) too. -
Page 15: Adjustment Procedure
ADJUSTMENTS ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open and check that the pres- sure upstream the gas train complies the value quoted on paragraph “Technical specifications”. Be sure that the mains switch is closed. Before starting up the burner, make sure that the return pipe to the tank is not obstructed. - Page 16 Before performing adjustments, it is necessary to prime the fule pump accroding to the next procedure: remove the burner cover; remove the solenoid valve coil B on pump P (Fig. 10) to avoid the light oil to get into the combustion chamber; start the burner up by means of the main switch and by means of the thermostats\pressure switches series;...
- Page 17 11 Checking the combustion values, adjust the air flow rate acting on the VSB screw (Fig. 10-Fig. 13); screw to decrease the flow rate and unscrew to increase it. 12 Turn the burner off and then on again. Fig. 13 Adjusting the combsution head Turn VRTclockwise or counterclockwise, according to the output to gain (minimum or maximum).

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 19: Routine Maintenance
PART III: MAINTENANCE At least once a year carry out the maintenance operations listed below. In the case of seasonal servicing, it is recommended to carry out the maintenance at the end of each heating season; in the case of continuous operation the maintenance is carried out every 6 months. - Page 20 Fig. 16 NOZZLE 60° 45° 60° G10 - G18 45° Tab. 2 Cleaning/replacing the electrodes ATTENTION: avoid the electrodes to get in touch with metallic parts (blast tube, head, etc.), otherwise the boiler operation would be compromised. Check the electrodes position after any intervention on the combustion head. To clean/replace the electrodes, proceed as follows: remove the combustion head as described in the previous paragraph;...
