Operation
HOB BURNERS
To light a burner, turn the relevant control knob anticlockwise to the
maximum position (
), then push it down to ignite the burner.
Upon, ignition, adjust the flame as required.
If the burner does not ignite, turn the control knob to zero, and try
again.
i
When switching on the mains, after installation or a power cut, it is
quite normal for the spark generator to be activated automatically.
To ensure maximum burner efficiency, you should only use pots and
pans with a flat bottom fitting the size of the burner used (see table).

As soon as a liquid starts boiling, turn down the flame so that it will
barely keep the liquid simmering.
If you use a saucepan which is smaller than the recommended size,
the flame will spread beyond the bottom of the vessel, causing the
handle to overheat.
Take care when frying food in hot oil or fat, as the overheated
splashes could easily ignite
If the control knobs become difficult to turn, please contact your local
AEG Service Force Centre.
7
Maintenance and Cleaning
Before any maintenance or cleaning can be carried out, you must
DISCONNECT the hob from the electricity supply.
The hob is best cleaned whilst it is still warm, as spillage can be
removed more easily than if it is left to cool.
The Hob Top
Regularly wipe over the hob top using a soft cloth well wrung out in
warm water to which a little washing up liquid has been added. Avoid
the use of the following:
- household detergent and bleaches;
- impregnated pads unsuitable for non-stick saucepans;
- steel wool pads;
- bath/sink stain removers.
Should the hob top become heavily soiled, it is recommended that a
cleaning product such as Hob Brite or Bar Keepers Friend is used.
Pan Supports
When washing the pan supports by hand, take care when drying them
as the enamelling process occasionally leaves rough edges. If necessary,
remove stubborn stains using a paste cleaner.
The Burners
The burner caps and crowns can be removed for cleaning.
Wash the burner caps and crowns using hot soapy water, and remove
marks with a mild paste cleaner. A well moistened soap impregnated
steel wool pad can be used with caution, if the marks are particularly
difficult to remove.
After cleaning, be sure to wipe dry with a soft cloth.

19
Electrical connections
Any electrical work required to install this hob should be carried out
by a qualified electrician or competent person, in accordance with the
current regulations.
THIS HOB MUST BE EARTHED.
The manufacturer declines any liability should these safety measures not be
observed.
This hob is designed to be connected to a 230-240V 50Hz AC electrical
supply.
Before switching on, make sure the electricity supply voltage is the same as
that indicated on the hob rating plate. The rating plate is located on the
bottom of the hob. A copy is attached on the back cover of this book.
The hob is supplied with a 3 core flexible supply cord incorporating a 3amp
plug fitted. In the event of having to change the fuse, a 3amp ASTA
approved (BS 1362) fuse must be used.
Should the plug need to be replaced for
any reason, the wires in the mains lead
are coloured in accordance with the
following code:
Green and Yellow - Earth
Blue
- Neutral
Brown
- Live
☞
FO 0390
1) Connect the green and yellow
(earth) wire to the terminal in the plug which is marked with the

letter 'E' or the earth symbol
2) Connect the blue (neutral) wire to the terminal in the plug which is
marked with the letter 'N' or coloured black.
3) Connect the brown (live) wire to the terminal in the plug which is
marked with the letter 'L' or coloured red.
Upon completion there must be no cut, or stray strands of wire present and
the cord clamp must be secure over the outer sheath.
In the event of having to change the fuse, a 3amp ASTA approved (BS 1362)
fuse must be used.
A cut off plug inserted into a 13 amp socket is a serious safety
(shock) hazard. Ensure that the cut off plug is disposed of safely.
20
Permanent Connection
In the case of a permanent connection, it is necessary that you install
a double pole switch between the hob and the electricity supply
(mains), with a minimum gap of 3 mm. between the switch contacts
and of a type suitable for the required load in compliance with the
current electric regulations.
The switch must not break the yellow and green earth cable at any
point.
Ensure that the hob supply cord does not come into contact with
surfaces with temperatures higher than 50 deg. C.
Replacement of the cable
The connection of the voltage cable to the appliance's terminal block
is of type "Y". This means that its replacement requires the specific
equipment of a technician.
In this case, only cable type H05RR-F must be used. The cable section
must be suitable to the voltage and the working temperature.
The yellow/green earth wire must be approximately 2 cm. longer than
the phase wires.

b) meter set on Ω (Ohm) x 100 scale.
Repeat test with leads from L to E. If meter reads less than ∞
(infinity) there is a fault.
NOTE - Should it be found that the fuse has failed but no fault is indicated a detailed continuity check (i.e. by disconnecting and checking each
component) is required to trace the faulty component.
It is possible that a fault could occur as a result of local burning/arcing but
no fault could be found under test. However a detailed visual inspection
should reveal evidence of burning around the fault.
