12.4 Final operations
After replacing the nozzles, reposition the flame-spreader crowns, the burner caps and the pan stands.
Following adjustment to a gas other than the one originally set in the factory, replace the gas setting
label fixed to the appliance with the one corresponding to the new gas. The label is inserted inside the
nozzle pack (where present).
12.4.1Adjusting the hob burner minimum for city or natural gas
Light the burner and turn it to the minimum position.
Extract the gas tap knob and turn the adjustment screw
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). Repeat the operation on all
the gas taps.
12.4.2Adjusting the hob burner minimum for LPG gas
In order to adjust the minimum setting with liquid gas, the screw at the side of the tap rod must be
tightened clockwise all the way.
