START­UP OIL SIDE
Adjusting the maximum oil flow rate
Put the selector on the oil operation. Adjust the oil pressure reading the value on the return manometer / pressure gauge according to
the nozzle tables provided in the appendix. Oil adjustment is accomplished through LAMTEC parameters setting. Refer to LAMTEC
manual attacched.
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 pre­setting
Air adjustment is accomplished through LAMTEC parameters setting. Refer to LAMTEC
manual attacched.

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.
Adjusting the valve TV
1. Remove the cap A of the pressure regulating valve TV.
2. Loosen the fixing nut B and use an Allen wrench on the screw C to
adjust the delivery oil pressure. To increase the pressure turn clockwise, to
decrease the pressure turn anticlockwise.
3. Tighten the nut B and pay attention not to turn also the adjusting screw.
4. Screw on the cap A, back to its previous position.
