WARNING
This appliance must be installed by a qualified professional in accordance with the
current regulations in the country where the appliance is installed and must only be
used in a well ventilated area. Read the guides before installing and using this
appliance.
Appliance categories (see pt. 1.2, page 25 “Installation”):
- Class 1: Free-standing cooking appliance not normally in direct contact with the kitchen
units or the surrounding walls.
-Class 2: Cooking appliance that can be integrated between two kitchen units, whose walls
can be in direct contact with the surrounding units. This type of appliance can be in
contact with only one kitchen unit during installation.
- Class 2 / Sub-Class 1: Class 2 appliance that can be free-standing or installed so that the
side panels are accessible.
Before installing the appliance, ensure that the local gas supply conditions (gas
type and pressure) and the adjustment of the appliance are compatible.
The adjustment conditions for this appliance are indicated on the label at the
back of the hob and on the test certificate.
Make sure that the gas supply is turned on and that the cooker is wired in and switched
on. The cooker needs electricity.
This appliance is not intended to be connected to a ventilation system or a ventilation shaft
for combustion products. It should be installed and connected in accordance with the
current regulations, and special attention should be paid to the applicable ventilation
regulations.
The use of a gas cooking appliance results in the production of heat and moisture in the
room where it is installed. Ensure that the room is well ventilated: keep natural ventilation
holes open or install a mechanical ventilation device (mechanical extractor hood).
Prolonged or intensive use of the appliance may call for additional ventilation, e.g. by
opening a window, or for more effective ventilation, by increasing the power of the
mechanical ventilation system installed.
When you first use your cooker it may give off a slight odour. This should stop after a little
use.
The parts that are protected by the manufacturer must not be manipulated by the installer
or the user.
Read all instructions before using this appliance. Save these instructions for future reference.

Please note:
The accessible parts may be hot when the oven is being used: keep young children at a safe
distance.
Children should be supervised to ensure that they do not play with the appliance.
If you smell gas:
u Don’t turn electric switches on or off.
u Don’t smoke.
u Don’t use naked flames.
u Do turn off the gas at the meter or cylinder.
u Do open doors and windows to get rid of the gas.
u Call your gas supplier.
The cooker should be serviced by a qualified service engineer and only approved spare
parts used. Have the installer show you the location of the cooker control switch. Mark it
for easy reference.
Always allow the cooker to cool and then switch off at the mains and before cleaning
or carrying out any maintenance work, unless specified otherwise in this guide or in an
“Instructions for use” guide.
All parts of the cooker become hot with use and will retain heat even after you have
stopped cooking. Take care when touching cooker, to minimize the possibility of burns,
always be certain that the controls are in the OFF position and that it is cool before
attempting to clean the cooker.
Clean with caution. If a wet sponge or cloth is used to wipe spills on a hot surface, be
careful to avoid steam burns.
Some cleansers can produce noxious fumes if applied to a hot surface.
DO NOT use a steam cleaner to clean the cooker.
Do not spray aerosols in the vicinity of the cooker while it is in on.
Do not store or use combustible materials, or flammable liquids in the vicinity of this
appliance.
Take great care when heating fats and oils, as they will ignite if they get too hot. Use
a deep fat thermometer whenever possible to prevent overheating fat beyond the smoking
point.
WARNING

6Notice d’installation ligne “Cornuchef” Centenaire - GB
08NOTINSTGSC100/GB-4
WARNINGWarning
Never leave a chip pan unattended. Always heat fat slowly, and watch as it heats.
Deep fry pans should be only one third full of fat. Filling the pan too full of fat can cause
spill over when food is added. If you use a combination of oils or fats in frying, stir them
together before heating, or as the fats melt.
Foods for frying should be as dry as possible. Frost on frozen foods or moisture on fresh
foods can cause hot fat to bubble up and over the sides of the pan.
Do not use the top of the flue (the slot along the back of the cooker) for warming
plates, dishes, drying tea towels or softening butter.
Take care that no water seeps into the appliance.
The oven should NOT be used for heating the kitchen, not only does this waste fuel
but the control knobs may become overheated.
When the oven is on DO NOT leave the oven door open for longer than necessary.
Before using the range make sure all the packing materials have been removed.
Destroy the carton and plastic bags after unpacking the range. Never allow children to play
with packaging material.
NEVER leave any items on the range cooktop. The hot air from an oven vent may ignite
flammable items and may increase pressure in closed containers, which may cause them
to burst.
Many aerosol-type spray cans are EXPLOSIVE when exposed to heat and may be highly
flammable.
Avoid their use or storage near an appliance.
Several types of plastic are combustible, and most of them can be damaged by heat.
Remove any objects made from paper, plastic or fabrics (such as cooking books, plastic
cooking utensils, towels, etc.) as well as flammable liquids from any parts of the range lia-
ble to get hot.
Preferably, there should be no cupboards or shelving above the appliance. In the event of
cupboards/shelving being above the appliance, make sure that they hold objects seldom
used, which can be safely kept in a place exposed to the heat generated by the appliance.
NEVER COVER the slits, apertures or holes in the bottom part of the appliance, and never
cover the grills with products such as aluminum foil; doing so would prevent air circula-
tion inside the oven and the aluminum foil could cause heat to build up leading to a risk
of fire.
DO NOT use the oven for storage.
WARNING

Notice d’installation ligne “Cornuchef” Centenaire - GB
08NOTINSTGSC100/GB-4
WarningWARNING
Flammable materials should not be stored in an oven or near the cooktop burners. This
includes paper, plastic and cloth items, such as cookbooks, plasticware and towels, as well
as flammable liquids.
NEVER TOUCH THE BURNER or the surfaces around the burner.
Note also that the burner can remain hot for a certain time even after it has been turned
off. Surfaces located around the gas burner can become sufficiently hot to cause burns.
Likewise, make sure that there is no contact between clothing and other flammable pro-
ducts and heating elements or appliance internal surfaces.
Wear appropriate clothing.
Do not use loose-fitting clothing (sleeves, etc.) when operating the appliance.
If there are shelves or cupboards above the appliance, be careful when reaching for pro-
ducts they might contain.
Flammable products can ignite on contact with a burner flame or a warm surface, leading
to serious burns.
Use only oven gloves or kitchen gloves that are dry.
Using wet gloves on warm surfaces can lead to burns caused by the vapor. Avoid all contact
between oven gloves and warm heating elements.
Never use a towel, thick cloth or similar instead of an insulating glove; they may catch fire
on contact with a hot surface.
Never operate the appliance using wet hands.
Make sure that your appliance has been correctly installed and grounded by a qualified
technician.
USE THE RIGHT SIZE PAN.
This appliance is equipped with burners of different sizes. Use utensils with flat bottoms.
Do not use unstable pans and position the handles away from the edge of the cooktop.
Make sure the flames are under the pans. It’s not safe to let the flames burn up the sides
of the pan; the handle may get too hot.
DO NOT use cooking vessels that may overlap the edges of the hotplate.
For induction hob, it is recommended not to leave any metallic utensils as knife, fork,
spoon or covers on the cooktop, as they may become hot.
