- 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 prepur-
