10. FINAL OPERATIONS FOR GAS APPLIANCES
After making the adjustments described above, reassemble the appliance
by following the instructions in point "9.1 Replacement of nozzles on the
hob" in reverse order.
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.
This label can be obtained from the nearest Authorised Service Centre.
10.1 Adjusting the minimum for natural gas
Light the burner and turn it to the minimum
position. Extract the gas tap knob 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 (turning the
knob rapidly from the maximum to the minimum
position the flame must not go out). Repeat the
operation on all the gas taps.
10.2 Adjusting the minimum for liquid gas
To adjust the minimum with liquid gas, 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
the table "9.2 Burner and nozzle characteristics table".
10.3 Lubrication of gas taps
Over time the gas taps may become difficult to turn and get blocked. Clean
them internally and replace the lubrication grease.
This operation must
be carried out by a specialised technician.
