Usage
3. You must keep the dial depressed so that the automatic ignition for the burner
operates.
4. You should hold down the control knob for 15 seconds after the flame has
ignited on the burner. If after 15 seconds the burner has not lit, stop operating
the device and wait at least 1 min before trying to ignite the burner again.
5. After this 15-second interval, you will be able to release the dial and set the
flame to your required level by turning the dial anti-clockwise.
6. The operating position MUST be at a position between the maximum and
minimum position.
7. To switch the burner off, turn the control dial clockwise to the gas off position.
Note: In case of power cut, the burners can be lit carefully by using a match.
Warnings:
•It is normal to hear a slight whistling noise while the burner is operating.
•When it is 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.
•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.
•An orange-coloured flame is normal. This is caused by the presence of dust in
the atmosphere, spilt liquids, etc.
•The kitchen will become hot and humid when this gas appliance is used. You
must therefore ensure that the kitchen is well ventilated: either keep the
natural ventilation apertures open, or install a ventilation system (extractor
hood).
•If using the appliance intensively for prolonged periods, you may require
additional ventilation (e.g. by opening a window) or more effective
ventilation (e.g. by increasing the hob's ventilation, if possible).
•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 one minute.

Usage
Pans & energy saving
The following advice is to prevent damage to pans and help you save energy:
16
Burners Suitable pan sizes (diameter)
Minimum diameter (mm) Maximum diameter (mm)
Triple 220mm 260mm
Rapid 180mm 220mm
Semi-rapid 180mm 200mm
Auxiliary 120mm 180mm
aX
Always use pans that are the right
size for each burner to avoid
wasting gas and discolouring the
pans
Do not use small pans on large
burners, the flame should never
touch
the sides of the pans
Place a lid on pans
Do not
cook without a lid or with
the lid half off, as this wastes
energy
Only use pans with a thick, flat
bottom.
Do not use damaged
pans, which
do not sit evenly on the hob: pans
may tip over.
Always place pans
centrally over
the burners not to one side
Do not place pans on one side of a
burner, as it could tip over
Do not use large
pans on burners
near the controls, as they may be
damaged by the high
temperatures
Pans
must always be put on the
pan supports. Always ensure the
pan supports and burner covers
are correctly positioned before use
Never place pans directly on the
burners
Do not place anything between
pan and pan support
Be careful
when handling pans
when they are on the burner or
have just be taken away from the
burner
Do not use excessive weight or
strike the hob with heavy
objects

Usage
Pan supports:
The pan supports will only align with the burners if they are put on the hob
correctly. To ensure this is done at the top of the hob there is a metal strip that
has raised notches on it; 2 on the left, 1 in the middle and 2 on the right. These
notches relate directly to the holes/indentations that are on the underside of the 3
pan supports. The middle pan support which is for the triple burner or wok burner
has 1 hole/indentation on its underside (this will be easy to identify as it can only
support a single large pan and the other pan supports can support 2). The left and
right pan supports have 2 holes/indentations on the underside. The thicker part of
the left and right pan supports should be on the outside when aligning them to the
correct notches. Place the pan supports on to them and the hob.

Cleaning and Maintenance:
How to clean:
•After each use, clean the surface of the respective burner parts once they have
cooled down. If any residue is left (baked-on food, drops of grease etc.),
however little, it will become stuck to the surface and more difficult to remove
later. The holes and grooves must be clean for the flame to ignite properly.
•The movement of some pans may leave metal residue on the pan supports.
•Clean the burners and pan supports using soapy water and scrub with a non-
wire brush.
•If the pan supports are fitted with rubber rests, ensure that these are also
cleaned. The rests may come loose and the pan support may scratch the hob.
•Always dry the burners and pan supports completely.
•Water droplets or damp patches on the hob at the start of cooking may
damage the enamel.
•After cleaning and drying the burners, make sure the burner covers are
correctly placed on the diffuser.
•Always clean off any liquid as soon as it is spilt: you will save yourself any
unnecessary effort.
•Do not leave acidic liquids (e.g. lemon juice, vinegar, etc.) on the hob.
•The ring cover of the double or triple flame burner and stainless steel parts
such as hotplate rings, top sheet and the area around the burners may become
discoloured over time. This is normal because of the high temperatures. Each
time the appliance is used these parts should be cleaned with a product that is
suitable for stainless steel.
CAUTION: The use of a gas cooking appliance results in the production of heat,
moisture and products of combustion" in the room in which it is installed. Ensure
that the kitchen. is well ventilated especially when the appliance is in use: keep
natural ventilation holes open or install a mechanical ventilation device
