VERIFY:
- That piping system is perfectly sealed;
- That the use of hoses is avoided whenever is possible (use copper pipes prefe-
rably);
- That depression is not greater than 0,45 bar, to avoid pump’s cavitation;
- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 22-24 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 prepurging, 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.

All burners are factory tested at 400V - 50Hz 3-phase for motors, and 230V - 50Hz single phase with neutral for
auxiliary equipments. Should it be necessary to power the burner with 230V - 50Hz, modify the connections on
motor and the terminal board as shown in the picture. Protect the burner supply line with suitable fuses and/or other
safety devices as required by the local regulations on the matter.
