Oil rate adjustment - Single stage burners
Priming the pump
Before carrying out the adjustment it is necessary to start up the fuel pump, proceeding as follows:
Prior to start up the burner, make sure that the return pipe to the tank is not obstructed. Any obstruction would
cause the pump seal to break.
Start the burner, light up the photoresistor after the opening of the solenoid valve and escape the air from the pressure port.
The fuel flow rate is set choosing a properly dimensioned nozzle and setting the inlet pressure on the pump (see the hydraulic
diagram in Fig. 34
To choose the correct nozzle refer to table Tab. 1; for setting of the pump pressure, see pag. 23.
Choosing oil nozzles
Tab. 1 - Choice of the oil nozzle - Single stage burners
Note: all pumps are set to 12 bar. The nozzle rate must be higher than the rate referred to the minimum burner
output.
