5.1 INCOMING PRESSURE CHECK (PE) FIG. 1
Pressure is measured with a manometer 0 ÷ 80mbar (precision at least 0.1mbar).
The pressure socket Fig. 1 is located on the G 1/2" gas ramp behind the panel; undo the screw (A) of the pressure socket (B),
attach the silicone rubber to the manometer, ignite the burner (Fig. 3 position 4) and take the incoming "dynamic" pressure.
Fasten the screw (A) back with a gas washer (C), check gas sealing with bubble soap.
5.2 NOZZLE PRESSURE CHECK (PI) FIG. 2
The pressure socket is located above the nozzle holder (Fig. 2).
The silicone rubber is prepared for high temperatures and should be protected with tin foil to avoid its burning, especially in
the oven or the cooking plate.
5.3

ADJUSTING THE MINIMUM THERMAL CAPACITY

The right minimum for thermal capacity is achieved by means of the "calibrated" bypass idle screw firmly tightened in
accordance with Table II.
Ignite the burner according to Chapter 6 "Instructions to Users" in the maximum position ( ); after approx. 15 minutes of pre-
heating, turn knob to the minimum position ( ).
For the 2nd and 3rd Family, the bypass idle screw should be fully screwed down.
5.4

LIQUID GAS OPERATION CONTROL

Check whether the fitted nozzles comply with the indications on Table II.
Check whether the incoming pressure complies with the indications on Table II.
Make sure that the L.P.G. gas system has two pressure regulators of suitable capacity and that the evaporation capacity is
sufficient. See also the publication "Installation Regulations and Characteristics of L.P.G. Systems".
5.5

OPERATION CONTROL

- Start the unit in accordance with the use instructions.
- Make sure there are no leaks following the local procedures.
- Check the ignition and interignition of the pilot burner and the main burner.
- Make sure the flue gases are discharged regularly.
- Write on a sticker, to be glued to the unit label, for what gas and pressure the unit has been calibrated
