Operation

Hob burners

To light a burner:

z push in the relevant control knob and turn it

anticlockwise to maximum position;

z 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). Burner minimum maximum

diameter diameter

Ultra-rapid
(triple-crown) 180 mm. 260 mm.
Large (rapid) 180 mm. 260 mm.
Medium (semi-rapid) 120 mm. 220 mm.
Small (auxiliary) 80 mm. 160 mm.

))

))

)

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.

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 and Wok Stand

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 stains using
a paste cleaner.

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.

Important safety requirements

This hob must be installed in accordance with the Gas
Safety (Installation and Use) Regulations (Current Edition)
and the IEE Wiring Regulations (Current Edition).

Provision for ventilation

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.
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.

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. 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. A minimum
distance of 100 mm. must be left between the side edges
of the hob and any adjacent cabinets or walls.

Cut Out Size

The dimensions of the cut-out are given in the diagram.

Installation

IMPORTANT:

This hob must be installed by a

competent person to the relevant Gas Standards.

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.

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). 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.

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.

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 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 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
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 cord clamp must be secure over
the outer sheath.

A cut off plug inserted into a 13 amp socket is
a seriuos safety (shock) hazard. Ensure that
the cut off plug is disposed of safely.

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.

Fault Finding

Preliminary Electrical Systems
Check

A. EARTH CONTINUITY CHECK - Appliance must

be electrically disconnected - meter set on Ω
(Ohms) x 1 scale and adjust zero if necessary.

a) Test leads from any appliance earth point to earth

pin on plug. Resistance should be less than

0.1 Ω (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 Ω (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 Ω (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 no fault could be found under
test. However a detailed visual inspection should
reveal evidence of burning around the fault.
