The pump is adjusted during testing and inspection to
12 bar. 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 prepurging, due to a fuel pressure
drop in the pump, rearm the burner's lock-out to restart the burner. Do not allow the pump to work 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.
