Installation  
IMPORTANT: This hob must be installed according  
to the instruction supplied, and by qualified and  
competent personnel to the relevant National  
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.  
FO 0264  
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.  
A) End of shaft with nut  
B ) Washer  
C) Elbow  
Gas Connection  
Connection to the gas supply should be with either rigid or  
semi-rigid pipe, i.e. steel or copper.  
It is important to install the elbow correctly,with the  
shoulder on the end of the thread, fitted to the hob  
connecting pipe.  
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.  
Failure to ensure the correct assembly will cause  
leakage of gas.  
Ensure that the main connection pipe does not exert any  
strain on the hob.  
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.

Electrical Connections  
THIS HO B MUST BE EARTHED.  
Permanent Connection  
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.  
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.  
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).  
The switch must not break the yellow and green earth cable  
at any point.  
Ensure that the hob supply cable does not  
come into contact with surfaces with  
temperatures higher than 50 deg. C.  
Electrical Connections  
Supply cable replacement  
This hob is designed to be connected to a 230 V 50 Hz AC  
electrical supply.  
The cable used to connect the hob to the electrical supply  
must comply to the specifications given below.  
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.  
Min. size Cable/flex Cable / flex type Fuse  
0.75 mm2  
H05 V2V2-F (T90)  
3 A  
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.  
The manufacturer declines any liability should  
these safety measures not be observed.  
Should the plug need to be replaced for any reason, the  
wires in the mains lead are coloured in accordance with the  
following code:  
Neutral  
Green andYellow - Earth  
Blue  
Brown  
- Neutral  
- Live  
— Connect the green and yellow (earth) wire to the  
terminal in the plug which is marked with the  
Earth (yellow/green)  
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.  
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.

Commissioning  
When the hob has been fully installed it will be necessary to  
check the minimum flame setting.To do this,follow the pro-  
cedure below.  
Turn the gas tap to the MAX position and ignite.  
Set the gas tap to the MIN flame position then turn the  
control knob from MIN to MAX several times.If the flame  
is unstable or is extinguished follow the procedure below.  
Procedure:  
Re-ignite the burner and set to MIN.  
Remove the control knob.  
To adjust, use a thin bladed screwdriver and turn  
the adjustment screw (see diagram) until the flame  
is steady and does not extinguish, when the knob  
is turned from MIN to MAX. Repeat this proce-  
dure for all burners.

Testing  
Remove left hand pan support and front left burner  
cap and crown.

Fit manometer tube over the injector.  
Turn on the burner gas supply and ignite another  
burner.  
The pressure reading should be nominally 20mbar  
and must be between 17 mbar and 25mbar.  
Turn off the burner supplies.  
Conversion from Natural Gas to LPG  
It is important to note that this model is designed for use  
with natural gas but can be converted for use with butane

Building In  
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.  
IMPORTANT: This hob must be installed according  
to the instruction supplied, and by qualified and  
competent personnel to the relevant National  
Standards.  
Please ensure that when the hob is installed it is easily  
accessible for the engineer in the event of a breakdown.

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

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).  
Hints and Tips  
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 fr ying 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 Repair agent.  
Cleaning the hob  
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;  
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.  
- bath/sink stain removers.  
Shouldthe hobtopbecome heavilysoiled, it isrecommended  
that a cleaning product such as Hob Brite or Bar Keepers  
Friend available from your John Lewis local branch is used.  
Pan Supports  
The pan supports are dishwasher proof. If washing them by  
hand, take care when drying them as the enamelling process  
occasionallyleavesroughedges.Ifnecessary,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,  
andremove markswithamildpaste cleaner.Awellmoistened  
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.
