When in use a gas cooking hob will produce heat and moisture in the  
room in which it has been installed. Ensure there is a continuous air  
supply, keeping air vents in good condition or installing a cooker hood  
with a venting hose.  
When using the hob for a long period of time, the ventilation should  
be improved, by opening a window or increasing the extractor speed.  
Do not use this hob if it is in contact with water. Do not operate the  
hob with wet hands.  
Ensure the control knobs are in the OFF’ position when not in use.  
When using other electrical appliances, ensure the cable does not  
come into contact with the hot surfaces of the cooking appliance.  
Unstable or misshapen pans should not be used on the hob as unstable  
pans can cause an accident by tipping or spillage.  
Never leave the hob unattended when cooking with oil and fats.  
Never use plastic or aluminium foil dishes on the hob.  
Perishable food, plastic items and areosols may be affected by heat  
and should not be stored above or below the hob unit.  
Service  
This hob should only be repaired or serviced by an authorised Service

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.  
When switching on the mains, after installation or a power cut, it is  
quite normal for the spark generator to be activated automatically.  
i
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.  
i
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.

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.

(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, Par. 2 and B.S. 6891  
Current Editions.  
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.

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  
- Live  
Brown  
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  
or coloured green and yellow.  
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.

Download from Www.Somanuals.com. All Manuals Search And Download.  
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.

A. EARTH CONTINUITY CHECK  
Appliance must be electrically disconnected - meter set on (Ohms) x  
1 scale and adjust zero if necessary.  
Test leads from any appliance earth point to earth pin on plug.  
Resistance should be less than 0.1 (Ohm), check all earth wires  
for continuity and all contacts are clean and tight.  
B. INSULATION CHECK  
Appliance electrically disconnected, all switches ON.  
a) meter set on (Ohms) x 1 scale.  
Test leads from L to N in appliance terminal block. If meter reads  
«0» then there is a short circuit.  
b) meter set on (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

1) Ensure that the gas taps are in the 'OFF' position  
2) Isolate the hob from the electricity supply  
3) Remove all pan supports, burner caps, rings, crowns and control knobs.  
4) With the aid of a 7mm box spanner the burner injectors can then be  
unscrewed and replaced by the appropriate LPG injectors.  
TO ADJUST THE GAS RATE  
With the aid of a thin bladed screwdriver completely tighten down the  
by pass adjustment screw, which is located down the centre of the gas  
tap control shaft. Upon completion stick the replacement rating plate  
on the under side of the hob.
