amp socket is a serious safety  
(shock) hazard. Ensure that the  
cut off plug is disposed of safely.  
Permanent Connection  
The hob is supplied with a 3 core flexible  
supply cables.  
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.  
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.  
The switch must not break the yellow and  
green earth cable at any point.  
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

If the burner does not ignite, turn the  
control knob to zero, and try again.  
If the burner accidentally goes out,  
turn the control knob to the “off”  
position and wait for at least 1  
minute before trying to light the  
burner again.

(Triple Crown)  
Do not keep the control knob  
pressed for more than  
A
15  
seconds. If the burner does not  
light even after 15 seconds,  
release the control knob, turn  
it to the "off" position and wait  
for at least 1 minute before  
trying to light the burner 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.  
When switching on the mains, after  
installation or a power cut, it is quite  
normal for the spark generator to be  
activated automatically.  
In the absence of electricity, ignition  
can occur without the electrical device;  
in this case, approach the burner with  
a flame, push the relevant knob down  
and turn it anti-clockwise until it  
reaches the “maximum” position.  
Using the hob correctly  
To ensure maximum burner efficiency, it is  
stronglyrecommendedthatyouuseonlypots  
and pans with a flat bottom fitting the size of  
the burner used, so that flame will not spread  
beyond the bottom of the vessel (see the  
table).

Use only pans or pots with flat bottom.

The stainless steel can become  
tarnished if excessively heated.  
Therefore prolonged cooking with  
potstones, earthenware pans or cast-  
iron plates is inadvisable.Also, do not  
use aluminium foil to protect the top  
during use.

Make sure pots do not protrude over  
the edges of the cooktop and that they  
are centrally positioned on the rings  
in order to obtain lower gas  
consumption.  
Do not place unstable or deformed  
pots on the rings: they could tip over  
or spill their contents, causing  
accidents.  
Pots must not enter the control  
zone.

Cleaning the hob  
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.  
This  
appliance  
cannot  
be  
cleaned with steam or with a  
steam cleaning machine.  
The Hob Top  
Regularly wipe over the hob top using a soft  
cloth well wrung out in warm water to which a  
little wasing 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, the  
following products are recommended:  
-Forstainlesssteelhobsuseaproprietarystainless  
steel cleaner.  
- For other hobs use Hob Brite or Bar Keepers  
Friend.  
Do not leave acid or alkaline  
substances (e.g. vinegar, salt,  
lemon juice, etc.) on the  
cooktop.  
Pan Supports  
The pan supports are not  
dishwasher proof; they must be  
washed by hand. Take care when  
drying them as the enamelling process  
20  
 
occasionally leaves rough edges. If  
necessary, remove stubborn stains  
using a paste cleaner.  
After cleaning, make sure that the pan  
supports are correctly positioned.  
YES  
NO  
To make burners work properly, ensure that  
pan supports are placed in a way that the arms  
are centred upon the burner as shown in the  
picture.  
Pay attention when replacing the  
pan supports in order to avoid  
damaging the hob top.  
Cast iron pan supports: take care when  
removing them. They are heavy and could  
damage the hob or your kitchen furniture if  
you let them fall.  
The Burners  
The burner caps and crowns can be removed  
for cleaning.  
Wash the burners 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 Ignition electrode  
The electric ignition is obtained through a  
ceramic electrode which contains a metal  
electrode (Fig. 1 - C). Keep these  
components very clean, to avoid difficult  
lighting, and check that the burner crown  
holes (Fig. 1 - B) are not obstructed.

Something Not Working?  
If the hob is not working correctly,please carry  
out the following checks before contacting  
your local Service Force Centre.  
SYMPTOM  
SOLUTION  
There is no spark when lighting

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.  
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.  
The gas ring burns unevenly.  
If after all these checks, your hob still does  
not operate correctly, contact your local  
Service Force Centre.  
Please note that it will be necessary to provide  
proof of purchase for any in-guarantee service
