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 cavitation;
- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 12 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 fee-
ding 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.
