Replace the nozzles of the hob burners
Before any modifications or conversion
to a kind of different 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.
Hob burners
•
Remove the pan supports;
•
Remove the caps and the burner crowns;
•
Using a No 7 socket spanner unscrew the
nozzles and replace them with those required
for the type of gas in use (see table no. 1).
Reassemble the parts following the same
procedure in reverse.
These burners do not need any primary air
regulation.
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 air.
Check that, turning the knob quickly from the
maximum position to the minimum one, the flame
does not go out.
