If the burner does not ignite, turn the control knob to
zero, and try again.
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).
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.
As soon as a liquid starts boiling, turn down the
flame so that it will barely keep the liquid
simmering.
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 Electrolux Service Force Centre.
Using the Wok Stand
A wok stand is provided to enable you to use a round
bottomed wok on the hob. The wok stand must only be
used on the central burner, and should not be used with
any other type of wok or pan.
When fitting the wok stand, ensure the recesses in the
frame fit securely onto the bars of the pan supports, as
shown in the diagram.
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
wrungoutinwarmwatertowhichalittlewashingupliquid
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
recommendedthatacleaningproductsuchasHobBrite
or Bar Keepers Friend is used.

Pan Supports and Wok Stand
To keep the pan supports in the correct position, they
are hooked into hinges at the back of the hob.
The pan supports can be lifted for easier cleaning, as
shown in Fig. 1.
To remove the pan supports completely, proceed as
shown in Fig. 2.
FO 2030
The pan supports and the Wok Stand are dishwasher

Something Not Working?
If the hob is not working correctly, please carry out the following checks before contacting your local Electrolux
Service Force Centre.
SYMPTOM
SOLUTION
n There is no spark when lighting the gas
u Check that the unit is plugged in and the electrical
supply is switched on
u Check that the RCCB has not tripped (if fitted)
u Check the mains fuse has not blown
u Check the burner cap and crown have been
replaced correctly, e.g. after cleaning.
u Check the main jet is not blocked and the burner
crown is clear of food particles.
n The gas ring burns unevenly
u Check the burner cap and crown have been
replaced correctly, e.g. after cleaning.
If after all these checks, your hob still does not operate
correctly, contact your local Electrolux Service Force
Centre.
In-guarantee customers should ensure that the
above checks have been made as the engineer will
make a charge if the fault is not a mechanical or
electrical breakdown.
Please note that it will be necessary to provide proof of
purchase for any in-guarantee service calls.

Important safety requirements
This hob must be installed in accordance with the Gas Safety (Installation

and Use) Regulations (Current Edition) and the IEE Wiring Regulations
(Current Edition). Detailed recommendations are contained in the following
British Standards Codes Of Practice: B.S. 6172/ B.S. 5440, Part 2 and B.S.
6891 Current Editions.
600 mm
The hob should not be installed in a bed sitting room with a volume of less
than 20 m3. If it is installed in a room of volume less than 5 m3 an air vent of
effective area of 110 cm2 is required. If it is installed in a room of volume
between 5 m3 and 10 m3 an air vent of effective area of 50 cm2 is required,
while if the volume exceeds 11 m3 no air vent is required. However, if the
room has a door which opens directly to the outside no air vent is required
even if the volume is between 5 m3 and 11 m3. If there are other fuel burning
appliances in the same room, B.S. 5440 Part 2 Current Edition, should be
consulted to determine the requisite air vent requirements.

The manufacturer will not accept liability, should
the above instructions or any of the other safety
instructions incorporated in this book be ignored.
WHEN THE HOB IS FIRST INSTALLED
Once the hob has been installed, it is important to
remove any protective materials, which were put
on in the factory.
On the end of the shaft, which includes the G 1/2"
threaded elbow, adjustment is fixed so that the washer
is fitted between the components as shown in the
diagram. Screw the parts together without using
excessive force.
FO 0264
A) End of shaft with nut
B) Washer
C) Elbow
Gas Connection
Connection to the gas supply should be with either rigid
or semi-rigid pipe, i.e. steel or copper. The connection
should be suitable for connecting to R 1/2" (1/2 BSP
male thread).
It is important to install the elbow correctly, with
the shoulder on the end of the thread, fitted to the
hob connecting pipe.
Failure to ensure the correct assembly will cause
leakage of gas.
When the final connection has been made, it is essential
that a thorough leak test is carried out on the hob and
installation. Ensure that the main connection pipe does
not exert any strain on the hob.

Building In
Building over a cupboard or

Building over a kitchen unit with

If the hob is to be installed above a cupboard or drawer it
will be necessary to fit a heat resistant board below the
base of the hob on the underside of the work surface.
It is also recommended to carry out the electrical
connection to the hob as shown in diagrams 1 and 2.
Proper arrangements must be taken in designing the
furniture unit, in order to avoid any contact with the bottom
of the hob which can be heated when it is operated. The
recommended solution is shown in diagram 3.
The panel fitted under the hob ("a") should be easily
removable to allow easy access if technical assistance
is needed. The space behind the kitchen unit ("b") can
be used for connections.

the front and rear edge and at 50 mm. from
the side edges, as shown in the diagram,
taking care that the seals meet without
overlapping;

Electrical connections
Any electrical work required to install this hob
Permanent Connection
should be carried out by a qualified electrician or
competent person, in accordance with the current
regulations.
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.
THIS HOB MUST BE EARTHED.
The manufacturer declines any liability should these
safety measures not be observed.
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.
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.
Supply cable replacement
The cable used to connect the hob to the electrical supply
must comply to the specifications given below.
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 3ampASTAapproved (BS 1362) fuse
must be used.

FO 0390
— Connect the brown (live) wire to the terminal in
the plug which is marked with the letter 'L' or

Upon completion there must be no cut, or stray strands
of wire present and the cord clamp must be secure over
the outer sheath.
A cut off plug inserted into a 13 amp socket is
a seriuos safety (shock) hazard. Ensure that
the cut off plug is disposed of safely.
