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

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.

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.

Fitting the Hob into the worktop  
Carry out the building in of the hob as follows:  
put the seals supplied with the hob, on the  
edges of the cut out: place them exactly on  
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.
