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.
Use only the suitable box wrench provided for
this operation to remove the nozzle, taking
care to not damage the electrodes. Fit the new
nozzle with the same care.
Note: Always check the position of electrodes
after having replaced the nozzle (see illustra-
tion). A wrong position could cause ignition
troubles.
