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

VERIFY:
- That piping system is perfectly sealed; - That the use of

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-
