Disposing of a household appliance separately avoids possible
negative consequences for the environment and health. It also
enables the constituent materials to be recovered, saving both energy
and resources. As a reminder of the need to dispose of household
appliances separately, the product is marked with a crossed-out
wheeled dustbin.
Please note:
• Induction hobs become hot and remain hot during and immediately
after use. Do not touch the hob until it has been allowed to cool.
• Keep children away from the appliance when in use.
• Never use the hob top for storage.
• Pan handles should never stand out beyond the edge of the
worktop. This will ensure children cannot reach them.
• Do not lean over the hob when it is in use.
• Follow the cleaning instructions carefully.
• Ensure the base of the saucepan is clean and dry before placing it
on the hob.
• Avoid hard shocks from cookware – the vitroceramic glass surface
is highly resistant but not unbreakable.

• Do not place hot lids flat on the hob top. A “suction” eect could
cause damage to the hob.
• Do not drag cookware across the hob top: in the long term, this
could cause damage to the hob.
• Do not store cleaning or flammable products in the unit below the
hob.
• Always use appropriate cookware.
• Do not cook unopened tins of food directly on the hob.
• Never put cooking foil or plastic materials on the ceramic surface
when the hob is hot. These materials could melt and cause
damage to the hob.
• This hob (Class 3) has been designed for use only as a cooking
appliance. Any other use should be considered incorrect and
therefore dangerous.
FOR THOSE WITH HEART PACEMAKERS OR ACTIVE IMPLANTS:
The function of this hob conforms to current electromagnetic
interference standards and thus is in total compliance with legal
requirements (2004/108/CE directives).
To avoid interference between your hob and a pacemaker, your

Cooking on Induction
The principle of induction cooking is based on magnetic eect.
When you put your cookware on an induction zone and switch it on,
the electronic boards in the hob produce induced currents in the base
of the cookware and instantly raise its temperature. This heat is then
transferred to the food inside the cookware.
The best cookware to use with induction cooking has thick flat bases,
as the heat will be better distributed so cooking more evenly.
Most cookware is compatible with induction cooking. There are three
ways to check the suitability of your cookware:
1. Using a magnet to see if the base of the pan is magnetic: if three
magnet sticks, then the cookware is compatible.
2. Place the pan on one of the cooking zones switched on to power
level 4: if the display remains on, then the cookware is
compatible. If the display flashes, the cookware cannot be used on
an induction hob.
3. Check the instructions or packaging of the pans for the symbols
indicating suitability for use with induction.

Fitting the Hob
Unpacking the hob:
Take care not to lose or mishandle any parts.
Fitting position of the hob:
This appliance must be installed a minimum of 50mm from any
back wall and a minimum of 180mm away from any adjacent vertical
surfaces, e.g. a tall cupboard end panel. This may be reduced to
100mm if the adjacent surface is resistant to fire (tiles or steel, for
example). These dimensions are shown in Fig.6.
Ventilation requirements:
This appliance must be installed to allow air to flow freely to the air
intake, from the air outlet and in the base and run of units into which
it is installed (Fig 4). Failure to allow sucient ventilation could cause
damage to the hob and constitutes incorrect installation, which is not
covered by the warranty.
Notes:
• This could be a simple slot cut out of the plinth, or a dedicated
ventilation grille.
• The furniture top rail should not be fitted to the unit. This allows the
induction hob to exhaust air into the kitchen space.
• The recommended ventilation sizes are for guidance only.
If tting a cooker hood above the hob:
If a cooker hood is to be installed above the hob, the height of the
hood above the hob must be at least 600mm (650mm is

recommended) (Fig.5). If the instructions supplied with the hood
dictate that the hood must be installed at a height greater than
600mm, then that height is the minimum required.
Wall furniture requirements:
The minimum height of any cabinet immediately above the hob is
900mm. The minimum height of any adjacent units (including light
pelmets) is 400mm, unless they are manufactured from a material
resistant to fire (steel, for example)
Notes:
• Do not position this appliance above a refrigeration unit. The heat
generated may cause the refrigeration unit to fail.
• This appliance is designed to be installed into cabinet units capable
of withstanding temperatures of 65°C or greater above ambient
temperature.
• Never place perishable foods, soft items such as tea towels,
cleaning products or flammable items in the cupboard or drawer
below the appliance.
Fig.3
Page 21

• If an oven is to be installed below the hob, the thermal safety
system on the hob will not allow the hob to be used at the same
time as a pyrolytic programme on the oven.
• The hob is equipped with an anti-overheating safety device that
can be activated if the hob is installed over an oven that is not
suciently ventilated. In the event that this occurs, the zone display
will show C. We recommend that you increase the ventilation of the
hob by creating an opening in the side of the cabinet (8 cm x 5 cm).
How to install the hob:

from the wall to the cut-out edge. The
distance from the hob, when fitted, to
the back wall is 50mm.
If a splashback/worktop upstand is
to be fitted, take this into account
when cutting the hole. The minimum
distance that the hob should be
positioned away from the rear wall or
splashback is 50mm.
2. Fix the foam seal underneath the
appliance by following the outline of
the worktop upon which the hob will
rest. This ensures an airtight seal with
the worktop. Do not use silicone type
sealant.
