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 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
