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.

VERIFY:
- That piping system is perfectly sealed.
- That the use of hoses is avoided whenever is possible (use copper pipes
preferably).
3
- That depression is not greater than 0,45 bar, to avoid pump's cavitation.
- That check valve is suitably designed for the duty.
