Output required by the burner = 900 : 0.9 = 1000 kW;
1000 : 2 = 500 KW per nozzle;
therefore, two equal, 60°, 12 bar nozzles are required:
1° = 10 GPH - 2° = 10 GPH,
or the following two different nozzles: 1° = 12 GPH - 2° = 8 GPH.

Nozzle assembly
Remove screw 1)(Fig. 11) and extract the internal part 2).
Fit two nozzles with the box spanner (16 mm) 1)(Fig. 12),
after having removed the plastic plugs 2).
Fitting the spanner through the central hole in the flame sta-
bility disk or loosen screws 1)(Fig. 13).
Remove disk 2)(Fig. 13) and replace the nozzles using the
wrench 3).
Do not use any sealing products such as gaskets,
sealing compound, or tape.
Be careful to avoid damaging the nozzle sealing
seat. The nozzles must be screwed into place
WARNING
tightly but not to the maximum torque value pro-
vided by the wrench.
The nozzle for the 1st stage of operation is the one lying beneath
the firing electrodes (Fig. 14).
