All burners are factory tested at 400 V - 50Hz 3-phase for motors, and 230V - 50Hz single phase with neutral for auxi-
liary 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.

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

VERIFY:
- That piping system is perfectly sealed;
- That the use of hoses is avoided whenever is possible (use copper
pipes preferably);
- That depression is not greater than 0,45 bar, to avoid pump's cavi-
tation;
- 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
