Instructions for the installer
9.6 Final operations
After making the adjustments described above, reassemble the appliance by
following the instructions in "9.1 Removing the hob top" in reverse order.
9.6.1 Adjusting the minimum for city and 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).
9.6.2 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 "9.2 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.
