5.2 Adaptation to different types of
gas
In case of operation with other types of gas,
the burner nozzles must be changed and
the minimum flame adjusted on the gas
cocks.
Replacing nozzles
1. Remove the grids, burner caps and
flame-spreader crowns to access the
burner casings.
2. Replace the nozzles using a 7 mm socket
wrench according to the gas to be used
(see “Gas types and Countries”).
3. Reposition the burners in their correct
seats.
Adjusting the minimum setting for natural
or town gas
Light the burner and turn it to the minimum
position. Extract the gas cock 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. Turn the knob rapidly from
the maximum to the minimum setting: The
flame should not go out. Repeat the
operation on all gas cocks.
Adjusting the minimum setting for LPG
Tighten the screw located at the side of the
tap rod clockwise all the way.
Lubricating the gas cocks
Over time the gas taps may become difficult
to turn and get blocked. Clean them
internally and replace the lubrication
grease.
Following adjustment to a gas
other than the one originally set in
the factory, replace the gas setting
label on the appliance with the
one corresponding to the new gas.
The label is inserted inside the
nozzle pack (where present).
Lubrication of the gas taps should
be performed by a specialised
technician.
