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.  
As soon as a liquid starts boiling, turn down the  
flame so that it will barely keep the liquid  
simmering.  
If the control knobs become difficult to turn, please  
contact your local Zanussi Service Force Centre.  
Maintenance and Cleaning  
Before any maintenance or cleaning can be carried  
out, you must DISCONNECT the hob from the  
electricity supply.

them fall down.  
To keep the pan supports in the correct position, they  
are hooked into hinges at the back of the hob. When  
removing the pan supports, lift them up as shown in the  
diagram. Never turn the pan supports on the hinges, this  
could damage them.  
Wash the pan supports using hot soapy water. If  
necessary, a paste cleaner or a soap impregnated steel  
wool pad can be used with caution.  
NO  
After cleaning, be sure to wipe dry with a soft cloth.  
Ignition electrode  
The electric ignition is obtained through a ceramic  
"electrode" and a metal electrode (Fig. 1 - letter C). Keep  
these components very clean, to avoid lighting difficulties,  
and check that the burner crown holes are not  
obstructed.  
Something Not Working?  
If the hob is not working correctly, please carry out the following checks before contacting your local Zanussi Service  
Force Centre.

Installation  
IMPORTANT: This hob must be installed by a  
competentpersontotherelevantGasStandards.  
Any gas installation must be carried out by a  
competent person.  
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  
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).  
A) End of shaft with nut  
B) Washer  
C) Elbow  
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  
drawer  
Building over a kitchen unit with  
door  
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.  
Dimensions are given in mm.
