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. 9). 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.

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. 7), and replace them with the ones

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

next page).

• With a socket spanner 7 unscrew and remove the

injectors (Fig. 1), and replace them with the ones

required for the type of gas in use (see 

table 2

):

• GZ 35:

a) Auxiliary burner and the semi-rapid burners: after

fitting the nozzles (Fig. 8, lett. "B") screw the provided

grid filter "A" (Ø 10) on them;
b) Rapid and double-crown burner: screw the provided

grid filter assembly "C"(Ø 16)  on it.

• Reassemble the parts, following the same procedure

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.
