washing-up liquid. Dry the individual parts carefully.

Making settings on the hob
Your hob is equipped with four gas burners. The following
information explains how to light the gas burners and set the
size of flame.

Openings on the burner cup must always be unobstructed. All
parts must be dry.

position
8
,the gas supply will be interrupted after 90 seconds.
No ignition occurs
If there is a power cut or if the ignition plugs are damp, you can
light the gas burners with a gas lighter or a match.
Warnings
It is normal to hear a soft whistling noise while the burner is
operating.
When first used, it is normal for the burner to give off odours.
This does not pose any risk and does not indicate a
malfunction. They will disappear in time.
An orange-coloured flame is normal. This is caused by the
presence of dust in the atmosphere, spilt liquids, etc.
If the burner flames are accidentally blown out, switch off the
burner operating control knob and do not try to relight it for at
least 1 minute.
A few seconds after the burner is switched off, a sound (thud)
will be produced. This is not a fault - this means that the safety
device is no longer operating.
Keep the burner as clean as possible. If the ignition sparkers
are dirty they will not light properly. Clean them periodically
using a small non-wire brush. Bear in mind that the ignition
sparkers must not suffer any serious impacts.
