Replacement of the nozzles
Before any modifications or adapt the
range to a different kind of gas, you must
DISCONNECT the cooker from the electricity
supply and ensure that all control knobs are in
the OFF position, and the appliance has cooled
completely.
Every appliance has spare nozzles for every gas. The
hole of each nozzle is marked on the nozzle,in
microns.
For changing the nozzles:
1. Remove the pan support;
2. Remove the burners;
3. Using a socket spanner 7, unscrew the nozzles
(see figure) and replace them with those required
for the type of gas in use (see table no. 2).
Put in place the burners and the pan supports.
Adjustment of minimum level of plate burners.
When changing the gas type, watch that the minimum
level be correct. A regular flame at minimum level is
about 4 mm; check that, turning quickly the knob from
the maximum to the minimum position, the burner
doesn't go out.
Adjustment of minimum level for the hob burners
The burner is correctly adjusted when the flame is
stable silent and goes out without any noise.
When changing the type of gas check that the
minimum level is correct. The air admission is correct
when the flame is about 4 mm in length.
The top burners do not need adjustment of primary

Check that, turning the knob quickly from the
maximum position to the minimum one, the flame
does not go out.
