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.

MAIOR P 15 AB : The pump is a two pressure level type. During the test phase, it is adjusted to 10÷11 bar

for low flame, and 15÷16 bar for high flame.

MAIOR P 25 AB : The pressure of SUNTEC AS 47 K pump is adjusted to 12 bar during the test phase.

MAIOR P 35 : The pressure of SUNTEC AS 67 B pump is adjusted to 12 bar during the test phase.

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-
