INSTALLATION
WHEN THE HOB IS FIRST INSTALLED
Any gas installation must be carried out by
a registered CORGI installer, and in
accordance with existing rules and
regulations.
Once the hob has been installed, it is
important to remove any protective
materials, which were put on in the factory.
The relevant instructions are to be found in the
second section of this manual.
Please, ensure that, once the hob is
installed, it is easily accessible for the
engineer in the event of a breakdown.

Operat ion
HOB BURNERS
To light a burner, push the relevant control knob in,
turn it anticlockwise to maximum position, and
depress the ignition pushbutton marked by a small
electric spark symbol. Then adjust the flame as
required.
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.
i
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.
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 Zanussi
Service Force Centre.

Main t en an ce an d Clean in g
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;
FO 2030
- impregnated pads unsuitable for non-stick saucepans;
- steel wool pads;
Fig. 1
- 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 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.
The pan supports and the Wok Stand are dishwasher
proof. If washing them by hand, take care when
drying them as the enamelling process occasionally
leaves rough edges. If necessay, remove stubborn
FO 2032
stains using a paste cleaner.
Fig. 2
The Burners
The burner caps and crowns can be removed for
cleaning.
Wash the burners taps 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.

Som et h in g Not Work in g?
If the hob is not working correctly, please carry out the following checks before contacting your local Zanussi
Service Force Centre.
SYMPTOM
SOLUTION
■ There is no spark when lighting the gas
◆ Check that the unit is plugged in and the electrical
supply is switched on
◆ Check that the RCCB has not tripped (if fitted)
◆ Check the mains fuse has not blown
◆ Check the burner cap and crown have been
replaced correctly, e.g. after cleaning.
■ The gas ring burns unevenly
◆ Check the main jet is not blocked and the burner
crown is clear of food particles.
◆ Check the burner cap and crown have been
replaced correctly, e.g. after cleaning.
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.
If after all these checks, your hob still does not
operate correctly, contact your local Zanussi Service
Force Centre.
Please note that it will be necessary to provide proof
of purchase for any in-guarantee service calls.

This hob must be installed in accordance with the Gas
Safety (Installation and Use) Regulations (Current
Edition) and the IEE Wiring Regulations (Current
Location
Edition).
The hob may be located in a kitchen, a kitchen/diner
or bed sitting room, but not in a bathroom or shower
room.
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.
Before making the cut out in the worktop ensure that
the edges of the hob that are to be near either a side or
rear wall have a minimum distance of 55 mm.
between the edge of the hob and the wall.
The minimum distance combustible material can be
fitted above the hob in line with the edges of the hob
is 420 mm. If it is fitted below 420 mm. a space of 50
mm. must be allowed from the edges of the hob.
The minimum distance combustible material can be
fitted directly above the hob is 700 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 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.
A minimum distance of 100 mm. must be left
between the side edges of the hob and any adjacent
cabinets or walls.
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.

If a 60 cm cooker hood is be installed above the hob,
ensure a minimum distance of 780 mm is left
between the hanging furniture units beside the cooker
hood (see diagram below).

IMPORTANT
This hob must be installed by qualified
personnel to the relevant British Standards.
Any gas installation must be carried out by
a registered CORGI installer.
The manufacturer will not accept liability,
should the above instructions or any of the
other safety instructions incorporated in this
book be ignored.
On the end of the shaft, which includes the GJ 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.
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
RC 1/2 (1/2 BSP male thread).
When the final connection has been made, it is
essential that a thorough leak test is carried out on the
hob and installation.
FO 0264
A) End of shaft with nut
B) Washer
C) Elbow
Ensure that the main connection pipe does not exert
any strain on the hob.
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.

Building over a cupboard or drawer
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

Building over a kitchen unit with door
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.

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;
• place the hob in the cut out, taking care that it
is centred;
• fix the hob with the relevant fixing clamps
and screws, as shown in the diagram. When
the screws have been tightened, the excess
seal can be removed.
