To identify the burners on your hob, refer to the drawings in “9.8 Arrangement of the burners on the

cooking hob”.

After making the adjustments described above, reassemble the appliance by

following the instructions in “9.1 Removing the hob top” in reverse order.

9.6 Adjusting the minimum setting for natural gas

Reposition the components on the burner and slide the

knobs onto the tap rods.

Light the burner and set it on the minimum position.

Extract the knob again and turn the adjustment screw

inside or next to the tap rod (depending on the model)

until the correct minimum flame is achieved.

Refit the knob and verify that the burner flame is stable

(when turning the knob rapidly from the maximum to the

minimum position the flame must not go out).

9.7 Adjusting the minimum setting for LPG

To adjust the minimum setting with LPG, you must tighten the screw inside or

next to the tap rod (depending on the model) fully in a clockwise direction. The

bypass diameters for each individual burner are shown in table “9.3 Adjustment

for LPG”.

After adjustment with a gas other than the preset one, replace the label on the

casing of the appliance with the label corresponding to the new gas. The label is

inserted inside the pack together with the nozzles.
