6. Adaptation to different types of gas

INJECTORS REPLACEMENT

•Remove the pan supports.

•Remove the burner's caps and crowns.

•With a socket spanner 7 unscrew and remove the injectors (Fig. 7), and replace them with the ones required for the type of gas in use (see table 2).

•Reassemble the parts, following the same procedu- re backwards.

•Replace the rating label (placed near the gas supply pipe) with the relevant one for the new type of gas supply. You can find this label in the package of the injectors supplied with the appliance.

Should the feeding gas pressure be different or variable compared with the required pressure, an appropriate pressure adjuster must be fitted on the gas supply pipe, in compliance with the rules in force.

ADJUSTMENT OF MINIMUM LEVEL

To adjust the minimum level of the burners, proceed as follows:

•Light the burner.

•Turn the knob on the minimum position.

•Remove the knob.

•With a thin screwdriver, adjust the by-pass screw (see Fig. 8). If changing from natural gas to LPG, completely tighten clockwise the screw, until a small regular flame is obtained.

•Finally check the flame does not go out when quickly turning the knob from the maximum position to the minimum position.

This procedure can easily be carried out, anyhow the hob has been positioned or built in the working top.
