START-UP OIL SIDE
Adjusting the maximum oil flow rate
Put the selector on the maximum operation. Adjust the oil pressure reading the value on the return manometer / pressure gauge
according to the nozzle tables provided in the appendix.
NOTE: the pump pressure is set from the factory at the pressure required nozzle pressure required as per table of nozzle selection in
appendix. If the output required is different from the one set from the factory the pressure can be adjusted according to the instruction
below.
Servomotor LAMTEC - Air damper motor pre-setting
Air adjustment is accomplished through LAMTEC parameters setting. Refer to LAMTEC

Adjusting the pump pressure
1 - INLET
2 - RETURN
3 - BLEED AND PRESSURE GAUGE PORT
4 - VACUUM GAUGE PORT
5 - PRESSURE ADJUSTMENT
6 - TO NOZZLE
The pump pressure is set at a value of 22-25 bar during the testing of burners.
Before starting the burner, bleed the air in the pump through the gauge port.
Fill the piping with light oil to facilitate the pump priming. Start the burner and check the pump feeding pressure.
In case the pump priming does not take place during the first pre-purging, with a consequent,
subsequent lock-out of the burner, rearm the burner's lock-out to restart, by pushing the button on the control box.
If, after a successful pump priming, the burner locks-out after the prepurging,
due to a fuel pressure drop in the pump, rearm the burner's lock-out to restart the burner.
Do never allow the pump working without oil for more than three minutes.
!
NOTE: before starting the burner, check that the return pipe is open. An eventual obstruction could damage the pump sealing device.
