5.3 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
taps.
Replacing nozzles
1. Remove the pan stands, 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 use (see
“Burner and nozzle characteristics
table”).
3. Replace the burners in the correct
position.
Adjusting the minimum setting for natural
or city 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.
Turn the knob rapidly from the maximum to
the minimum setting: the flame should not go
out. Repeat the operation on all gas taps.
Adjusting the minimum setting for LPG
Tighten the screw located at the side of the
tap rod clockwise all the way.
Lubrication of gas taps
Over time the gas taps may become difficult
to turn and get blocked. Clean them
internally and replace the lubrication
grease.
The appliance is pre-set for natural
gas at a pressure of 1.0 kPa.
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).
The greasing of the gas taps
should be performed by a
specialised technician.
