4 FINAL OPERATIONS
After carrying out the above adjustments, remount in reverse order to the
instructions given in paragraph “3.1 Replacement of nozzles on the hob”.
After having regulated the device with gas other than the one tested,
replace the label located on the guard with the one that corresponds to
the new gas.
The label is available from your nearest Authorised Assistance Centre.
4.1 Regulation of minimum for town gas and natural gas
Light the burner and set it at minimum position.
Remove the knob and turn the regulation screw
inside or next to the gas tap pin (depending on the
model) until you get a suitable minimum flame.
Replace the knob and check burner flame stability:
(when you turn the knob quickly from maximum to
minimum position, the flame should not go out).
Repeat this operation for all the gas taps.
4.2 Regulation of minimum for LPG
To regulate the minimum for LPG, fully tighten the screw inside or next to
the gas tap pin (depending on the model) in a clockwise direction.
The diameters of the by-passes for each burner are given in table “3.2
Burner and nozzle characteristics table”.
4.3 Lubrication of gas taps
With time it may happen that the gas taps get blocked and hard to turn.
Clean them inside and re-grease them. This operation must be done
by an authorised person.
