REPLACING THE PILOT BURNER NOZZLE

N.B.: Using a size-10 spanner, we advise to first remove the spark plug (Fig. 6 position 4) because it can easily break.
The pilot burner is of the "Targhet" type, that is, with no primary air regulation, and has fixed nozzles.
Unscrew the nut with a size-10 spanner (Fig. 6 position 4) and remove the nozzle (Fig. 6 position 5). The nozzle is hooked to
the bicone (Fig. 6 position 3). Replace the pilot nozzle with one corresponding to the gas type chosen, according to Table II
Injectors Ch 2.6 Tighten the nut firmly with a size-10 spanner.

REPLACING THE IDLE BYPASS SCREW

The minimal thermal capacity screw or "Bypass" (Fig. 2 position 1) is located on the gas cock.
Unscrew with a screwdriver the idle screw and replace it with the one corresponding to the gas selected and in accordance with
Table II Injectors Ch. 2.6 The idle screw should be firmly screwed down into its housing. Ignite the pilot burner and turn the
knob to the minimum position, then proceed to adjust the minimum capacity if necessary (Fig. 2 position 1) following Table
II Injectors Ch. 2.6 Check the nozzle's minimum pressure.
Thermal capacity in the minimum position should be approx. 50% of the nominal thermal capacity.
The cooking plate burner should not go off when quickly turning the knob from the maximum position ( ) to the minimum
one ( ). The idle screw ought to be firmly tightened when it has a calibrated hole (see Table).
After replacing the nozzles, apply on the existing label the one supplied with the machine indicating the new type of gas.
