Injector pressure control
The pressure is measured with a 0 ÷ 80 mbar pressure measurer.
The pressure intake is placed usually above the nozzle holder,
•
Close the cut-off cock upstream the machine (Fig. 1 page 5);
•
unscrew the pressure intake screw (Fig. 4);
•
place the instrument for the detection (pressure measurer);
•
Open the cut-off cock upstream the equipment (Fig. 2 page 5);
•
turn on the burners at the maximum power and detect the pres-
sure read by the instrument.
Once the read-out is finished:
•
Close the cut-off cock upstream the machine (Fig. 1 page 5).
•
Reassemble the screw with gas seal washer in the appropriate
seat, open the cut-off cock upstream the machine (Fig. 2 page
5) and check by turning the burner on, that there are no gas leak-
ages.

If the measured pressure is lower than the 20% compared to the entry pressure,
suspend the installation and contact the customer care service.
If the measured pressure is higher than the entry pressure, suspend the installation
and contact the customer care service.
Replacement of pilot burner injector
•
Close the cut-off cock upstream the machine.
•
Demount if necessary, the plugs in order to avoid to damage it
during the injector replacement (Fig. 2).
•
Unscrew the nut and demount the pilot injector (the injector is
hooked to the compression fitting).
•
Replace the pilot injector (Fig. 1) with the one corresponding to
the selected gas according to what reported in the reference
Table.
•
Screw the nut with the new injector.
•
Reassemble the plug.
•
Turn on the pilot burner to check whether
there are no gas leakages.
