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 bur-
ner. Do never allow the pump working 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 by the same care.
Note: Always check the position of electrodes after having replaced the nozzle (see illustration). A wrong posi-
tion could cause ignition troubles.
