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 illustration). A wrong posi-
tion could cause ignition troubles.

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 22 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.
