PRIMING AND ADJUSTMENT OF OIL PUMP

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 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 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 suc-
cessful pump priming, the burner locks-out after the prepurging, due to a fuel pressu-
re 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 even-
tual obstruction could damage the pump sealing device.
