8. Adaptation to different types of gas

REPLACEMENT OF INJECTORS

• Remove the pan supports.

• Remove the burner's caps and crowns.

• With a socket spanner 7 unscrew and remove the

injectors (Fig. 10), and replace them with the ones

required for the type of gas in use (see table on the

next page).

• 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 (for non-LPG) 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. 11). 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.
