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
cocks.
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
gas
Light the burner and turn it to the minimum
position. Extract the gas cock knob and turn
the adjustment screw next to the cock 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
cock rod clockwise all the way.
Lubrication of gas cocks
Over time the gas cocks 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 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 cocks
should be performed by
authorised persons.
