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.
Burner and nozzle characteristics tables
The nozzles not provided are available at Authorised Service Centres.
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.
