Gas burners
There are indications to show which burner each control knob
operates.
It is essential to ensure that all the burner parts and pan
supports are correctly installed for the appliance to work
correctly. Do not swap the burner caps around.

Warnings
It is normal to hear a soft whistling noise while the burner is

2. Use any type of lighter or flame (cigarette lighter, matches,
When first used, it is normal for the burner to give off odours.
This does not pose any risk and does not indicate a
malfunction. They will disappear in time.

presence of dust in the atmosphere, spilt liquids, etc.
etc.) and bring it close to the burner.
If your hob can be switched on automatically (ignition
sparkers):
1. Press the chosen burner control knob and turn it
anticlockwise to the maximum power setting.
While the control knob is still pressed down, sparks are
produced on all burners. The flame ignites.
2. Release the control knob.
3. Turn the control knob to the required setting.
If it does not come on, turn the control knob to the off setting
and repeat the steps above. This time, press and hold the
control knob for longer (up to 10 seconds).
: Risk of deflagration!
If after 15 seconds the flame does not ignite, switch off the
burner and open a nearby window or door. Wait at least one
minute before trying to switch the burner back on.
Safety system
Depending on the model, your hob may have a safety system
(thermocouple) that prevents the flow of gas if the burners
accidentally switch off.
LJQLWLRQVSDUNHU
WKHUPRFRXSOH
To ensure that this device is active:
1. Switch on the burner as usual.
2. Without releasing the control knob, press and hold it down
firmly for 4 seconds after lighting the flame.
Switching off a burner
Turn the corresponding control knob clockwise to the 0 setting.
6
If the burner flames are accidentally blown out, switch off the
burner operating control knob and do not try to relight it for at
least 1 minute.
A few seconds after the burner is switched off, a sound (thud)
will be produced. This is not a fault - this means that the safety
device is no longer operating.
Keep the burner as clean as possible. If the ignition sparkers
are dirty they will not light properly. Clean them periodically
using a small non-wire brush. Bear in mind that the ignition
sparkers must not suffer any serious impacts.

Electric hob
Before using the hob for the first time, heat it up for 5 minutes,
set to full power, with no pans placed on it. At this point it is
normal to notice smoke and odours, but these will disappear
over time. Do not operate the hobs without placing pans on top,
except during this initial heating phase.
Power control switch
The electric hob is controlled by a switch, which can be used to
choose the power required for the food you are cooking.
When you begin cooking, we recommend turning the control
knob up to the maximum setting and then, depending on the
quantity and quality of the foods being cooked, turn down the
heat to a medium setting.
Taking advantage of the thermal inertia of the hob, the hob can
be switched off shortly before you finish cooking. This will save
energy as food will continue to cook using the heat retained in
it.
If prolonged use has worn away the surface of the electric
hobs, sprinkle them with a few drops of oil or other
maintenance products that are widely available.
Use perfectly flat, thick bottom pans of a similar size to the
hotplate, never smaller.
Do not spill liquid on the hob's surface, or use wet pans on it.
To switch on the hob:
Bearing in mind the type of cooking and the quantity of food,
using the table below as a guide, turn the control knob to the
left, selecting the setting for the dish you want to cook. The
operating indicator will light up.
To switch off the hob:
Turn the control knob to the 0 setting. The operating indicator
will go out.

Precautions for use
The following advice is intended to help you save energy and
prevent pan damage:
Use pans which are the right
size for each burner.
Do not use small pans on
large burners. The flame must
not touch the sides of the pan.
Do not use damaged pans,
which do not sit evenly on the
hob. Pans may tip over.
Only use pans with a thick, flat
base.
Do not cook without using a lid
and make sure the lid is
properly fitted. This wastes
energy.
Always centre the pan over the
burner, not to one side.
Otherwise it could tip over.
Do not place large pans on the
burners near the control
knobs. These may be
damaged by the very high
temperatures.
7
Place the pans on the pan
supports, never directly on the
burner.
Never use two burners or heat
sources to heat one single
pan.
Make sure that the pan
supports and burner caps are
correctly positioned before
using the appliance.
Pans should be placed on the
hob carefully.
Do not use grill pans,
earthenware casserole dishes,
etc. for a long period of time
on maximum power.
Do not strike the hob and do
not place excessive weight on
it.
Cleaning and maintenance
Cleaning
Caution!
Once the appliance is cool, use a sponge to clean it with soap
and water.
■
■
Do not use steam cleaners. This could damage the hob.
Never use abrasive products, steel scourers, sharp
implements, knives, etc. to remove bits of hardened food
from the hob.
After each use, clean the surface of the respective burner parts
once they have cooled down. If any residue is left (baked-on
food, drops of grease etc.), however little, it will become stuck
to the surface and more difficult to remove later. The holes and
grooves must be clean for the flame to ignite properly.
■
The movement of some pans may leave metal residue on the
pan supports.
Maintenance
Clean the burners and pan supports using soapy water and
scrub with a non-wire brush.
Always clean off any liquid as soon as it is spilt. This will
prevent food remains from sticking to the hob surface and you
will save yourself any unnecessary effort.
If the pan supports are fitted with rubber rests, ensure that
these are also cleaned. The rests may come loose and the pan
support may scratch the hob.
Always dry the burners and pan supports completely. Water
droplets or damp patches on the hob at the start of cooking
may damage the enamel.
After cleaning and drying the burners, make sure the burner
caps are correctly positioned on the diffuser.
Do not use knives, scrapers or similar implements to clean
the point where the glass meets the burner trims, the metal
frames or the glass/aluminium panels, if fitted.
Never slide pans across the glass surface, as you may scratch
it. In addition, try not to drop heavy or sharp objects on the
glass. Never strike any part of the hob.
Grains of sand that may come from cleaning fruits and
vegetables will scratch the glass surface.
Melted sugar, or foods which contain a lot of sugar which may
have spilt, should be cleaned off the hotplate immediately,
using the glass scraper.
Avoid spilling salt on the surface of the electric hob.
