Page 9
1 Safety precautions
Caution: Risk of toxic fumes!
▪ A gas hob produces heat, moisture and combustion by-products in the
room in which it is used. Ensure the kitchen is well ventilated, especially
when the hob is in use: keep natural ventilation holes open or install a
mechanical ventilation device (extractor hood). Prolonged intensive use of
the appliance may call for additional or more effective ventilation: open a
window or increase the extraction rate of the range hood.
Caution: Fire hazard!
▪ The cooking zones become very hot. Do not rest any objects on the hob.
▪ Do not store or use corrosive, chemical or flammable cleaning products or
products underneath or near to this household appliance.
Caution: Burns hazard!
▪ Overheated fat and oil can easily catch fire. Never attempt to extinguish
burning oil or fat with water. Danger of explosion! Smother the flames with a
fire blanket. Keep doors and windows closed.
▪ Exercise care when touching cookware handles as they can become hot.
Caution: Risk of injury!
▪ Cookware that is damaged, is not the right size or is not positioned cor-
rectly can cause serious damage. Check the cookware is fit for purpose before use. Centre the cookware in the middle of the relevant cooking zone.
Follow the tips and warnings that come with suitable cookware.
▪ In the event of a malfunction, turn off the gas and electrical supply to the ap-
pliance. Call our Customer Services.
▪ Do not tamper inside the appliance. If necessary, please call our Customer
Services.
▪ Use of unsuitable protective guards can cause accidents.
▪ Keep pets away from the appliance.
Caution: Risk to life!
▪ Packaging materials, e.g. plastic film and polystyrene, can be dangerous for
children. Danger of suffocation! Keep packaging material away from children.
How to avoid damaging the appliance

1 Safety precautions
▪ Do not climb on to the appliance.
▪ Do not cut or prepare food on the surface and avoid impact with hard ob-
jects. Do not drag cookware across the surface.
▪ Do not allow food to get onto the surfaces when they are hot, as it can dam-
age them. If food were to get onto the surfaces when they are hot, it must
be cleaned off straightaway.
▪ Do not leave the appliance unattended when in use.
▪ Only use cookware that is suitable for cooking with gas.
▪ Moving pans and cookware around causes scratches. This can be largely
prevented by lifting pans and cookware up and then placing them down in
position.
▪ The hob is designed to be used – signs of use, such as scratches or the
wear and tear from pans and cookware, are normal. The more intensively it
is used, the greater the signs of use; however, the appliance remains in perfect working order and therefore does not give a right of complaint. Safety is
guaranteed at all times.
1.5 Warnings
Please observe the notes on use in the «Cookware» (see page 18)
section.
▪ It is normal for a new appliance to give off an unpleasant smell when it is
first used. It does not indicate the existence of a danger or a defect. The
smell will fade over time.
▪ The colour of the flame can sometimes be orange. This is normal. It occurs
when there is dust in the air, when some liquid spills over, etc.
▪ A noise can be heard a few seconds after the burner is turned on and off.
This is normal. It indicates that the safety system has opened or shut down
the flow of gas.
▪ Ensure that the appliance is kept clean. If the ignition sparkers or thermo-
couples are dirty, the burners will not light or work properly. Clean the ignition sparkers and thermocouples periodically using a small non-wire brush.
Ensure that the ignition sparkers and thermocouples receive no hard
knocks.

appliance, this is to be carried out by a certified installer!
Safety
▪ Disable the appliance to prevent accidents caused by improper use, espe-
cially through children playing.
▪ Pull the plug out of the mains socket or have the appliance disconnected
from the mains by an electrician. Then cut the mains cable off flush with the
appliance.

4.4 Automatic re-ignition
All hobs have automatic re-ignition.
If a flame is extinguished, the appliance automatically attempts to reignite it. If the attempt to reignite it fails, the burner switches off.
Risk of deflagration: Ventilate the room well!
If the flame does not ignite after 15 seconds, switch off the burner and
open a door or window. Wait for at least a minute before trying again.
4.5 Safety system
The appliance has a safety system which continuously monitors the flame of
each burner. It prevents the flow of gas if a burner accidentally goes out.
If the flame does not touch the thermocouple, the appliance automatically attempts to ignite a flame again. If the attempt to ignite it fails, a valve stops the
flow of gas to the relevant burner.

Page 19
4 Appliance description
▪ The mocha support is only suitable for
use with mocha coffee makers and pots
with a diameter of at least 8 cm.
▪ The mocha support fits on all cooking
zones. The best heat transfer is achieved
on the economy and wok burners (inner
ring).
Take care that the burner flame only reaches as far as the base of
the mocha pot. The mocha pot handle could otherwise get hot.
We recommend the mocha support be used on the wok, economy or
standard burners.
Note on use
The following tips will help you to save energy and prevent damaging the
cookware and the appliance:
▪ The diameter of the base of the cook-
ware should correspond to the size of
the relevant burner.
▪ Do not place small-diameter cookware
on the large burners. The flame should
not touch the sides of the cookware.
▪ Cookware bases should not be de-
formed and stand stably on the cooking
zone. There is otherwise a risk of tipping
if the base is deformed.
▪ Only use cookware with a flat, thick
base.
▪ Always use a lid and make sure that it
fits properly, otherwise a lot of energy
will be wasted.
19
Page 20
4 Appliance description
▪ Always centre the cookware over the
burner, otherwise it could tip over.
▪ Do not place large pans on the burners
near the operating elements, as these
could overheat and become damaged.
Ensure that the cookware does not protrude over the edge of the
hob.
▪ Place pans on the pan supports, never
directly on the burners.
▪ Make sure that the pan supports, the
gas burners and the burner caps are positioned correctly before use.
▪ Cookware standing on a cooking zone
should be handled carefully.
▪ Do not strike the cooking zone or put
heavy objects on it.
▪ Place the wok horizontally on the wok
support.

7 Care and cleaning
Do not use any flammable, abrasive, chlorine- or bleach-containing
cleaning agents to clean the appliance. Only use standard food-grade
cleaning agents.
Under no circumstances use metal or steel brushes, copper cloths or
products that contain sand or scratch for cleaning.
Do not use a steam cleaner to clean the hob, as this could damage it.
Do not use abrasive cleaners, metal scourers, sharp objects, knives or
the like, for removing dried-on food residue from the hob.
7.1 Care
▪ If any liquid boils over, clean it off immediately to prevent it from burning on.
▪ Remove any grains of sand (e.g. from cleaning vegetables) immediately, as
they could scratch the surface of the hob.
7.2 Cleaning
▪ After cooking, allow the appliance to cool down before cleaning it. Clean
the surface with a sponge, water and a mild cleaning agent. For hobs with a
stainless steel surface, use a chrome steel cleaner for the best cleaning results. Always clean in the direction of the original polish lines.
▪ If dirty, clean the surface of each individual part of the burner when cold
with a sponge, water and mild cleaning agent and rinse off thoroughly with
water. Residue (food that has boiled over, fat splashes, etc.) can eat into
the surface and be very difficult to remove later. For a uniform flame, the
holes and grooves in the burner must always be kept clean.
▪ Pan supports can be cleaned in a dishwasher or by hand. Ensure that the
silicone feet do not come off the pan supports.
▪ Always dry the burners and the pan supports after cleaning them. Water
droplets or damp patches on the hob at the start of cooking may damage
the enamel. After cleaning and drying the burner rings and caps, position
them centrally on the corresponding burners.
