Replacing nozzles
1. Remove the pan supports, burner caps and
flame-spreader crowns to access the burner
cups.
2. Replace the nozzles using a 7-mm wrench
according to the type of gas to be used (see
the “Burner and nozzle characteristics
table”).
3. Replace the burners in their respective
housings.
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 gas cock spindle
(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 cock
spindle clockwise all the way.
Lubricating the gas cocks
Over time the gas cocks may become difficult to
turn and get blocked. Clean them internally and
replace the lubrication grease.
Gas types and Countries
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 cocks should be
performed by a specialised technician.
