5. After having replaced the nozzle, put the
burner back in its original position.

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.
Adjusting the gas oven burner minimum
setting
The oven thermostat is equipped with a screw
for adjusting the minimum. When changing the
type of supplied gas, the minimum must be
adjusted as follows:
1 Light the oven burner and run it at full power
for 10-15 minutes with the door closed and
without the shelf. Then turn the knob to the
minimum temperature.
2 Slide off the knob and insert a straight edge
screwdriver to make the adjustment.
3 If using liquid gas the adjustment screw must
be tightened clockwise to the very end.
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.
Burner and nozzle characteristics tables
Make sure you do not damage the
thermocouple or igniter
during these operations.
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.
