kept away until it has cooled.
During UseDuring Use
During UseDuring Use
During Use
!This hob is intended for domestic cooking only. It is not
designed for commercial or industrial purposes.
•Appliances become very hot with use, and retain their
heat for long periods after use. Care should be taken to
avoid touching heating elements inside the hob.
•Always stand back from the hob when opening the
hob door during cooking or at the end of it to allow
any build up of steam or heat to release.
!When in use a gas cooking appliance 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 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 they can cause an accident by tipping or spillage.
!Never leave the hob unattended when cooking with oil
and fats.

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.
Electrical RequirementsElectrical Requirements
Electrical RequirementsElectrical Requirements
Electrical Requirements
Any permanent electrical installation must comply with the
latest I.E.E. Regulations and local Electricity Board regulations.
For your own safety this should be undertaken by a qualified
electrician, e.g. your local Electricity Board, or a contractor
who is on the roll of the National Inspection Council for
Electrical Installation Contracting (NICEIC).
Electrical Connections
This hob is designed to be connected to a 230 V 50 Hz 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 cables.
This has to be provided with a proper plug, able to support
the load marked on the identification plate.To connect the
plug to the cable, follow the recommendation given in diagram
aside. The plug has to be fitted in a proper socket.
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
Brown - Live
— 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.
— Connect the blue (neutral) wire to the terminal
in the plug which is marked with the letter 'N' or
coloured black.
— 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 cable clamp must be secure over the
outer sheath.

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.

It is possible that a fault could occur as a result of
local burning/arcing but no fault could be found under

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.

Before fitting the hob into the cut out, an adhesive seal must
be fitted to the underside outside edge of the hob. It is
essential that no gaps are left in this seal in order to prevent
spillage near the hob seeping into the cabinet below.
1) Remove the pan supports, the burners caps and
crowns and turn the hob upside down, taking
care the ignition candles are not damaged in this
operation.
2) Place the sealing gasket all around the glass top
edge as shown in diagram 4.
3) Fit the hob in the cut out and push it down until
the glass top and the working top make contact,
as shown in diagram 5.

Detailed recommendations are contained in the following
National Standards Codes Of Practice: B.S. 6172/ B.S. 5440,
Part 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 m3an air vent of effective area of 110
cm2is required. If it is installed in a room of volume between
5 m3and 10 m3an air vent of effective area of 50 cm2is
required, while if the volume exceeds 11 m3no 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 re-
quisite air vent requirements.

LocationLocation
Location
The hob may be located in a kitchen, a kitchen/diner or bed
sitting room, but not in a bathroom or shower room.
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 is 400 mm - without a cooker hood above
see fig.6. If it is fitted below 400 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 - with a cooker hood above see fig.7. A minimum
distance of 100 mm must be left between the side edges of

To light a burner:
!push in the relevant control and turn it to maximum
position;
!then adjust the flame as required.
!If the burner does not ignite, turn the control knob to
zero, and try again.
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 Service Force Centre.

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.

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.
The cap and crown of each burner (except for the central
burner) are secured with two screws.To separate the two
pieces, lift the crown, turn it upside down, then undo the
two fixing screws as shown in fig. 4.
After cleaning, reassemble the two parts and refit the cap on
its correct position on the burner.

The electric ignition is obtained through a ceramic "electrode"
and a metal electrode (fig. 1 - letter C). Keep these
components well clean, to avoid difficult lighting, and check
that the burner crown holes are not obstructed.
