3 Installation and operation
3.1 Installation and operation safety
WARNING
Fatal injury caused by explosive gas
yGas connections must all be installed by a professional gas tter.
yOnly operate gas hobs in a well-ventilated, sufciently large room (at least 20 m³) or install a
mechanical ventilation device, e.g. a cooker hood. Take account of ventilation when making
constructional changes to buildings.
Fatal injury caused by re
yNever install gas hobs near ammable items, e.g. decorations.
yUse heat-resistant wall connection strips which do not rest more than 30 mm on the worktop.
yFor combustible installation walls:
○Minimum clearance at the back: 50 mm (wall made of heat-resistant material, no sockets,
no wood, no plastic materials, etc.)
○Minimum clearance on the left and right: 50 mm
○Minimum clearance to cooker hoods or wall units installed above the hobs: 650 mm
Fatal injury caused by electricity
yCables may not come into contact with hot parts.
yDo not bend cables or install them direct on sharp edges.
yCheck electrical connections, see Section 6 “Technical data”.
Serious burns caused by fat explosions
yNever extinguish burning fat with water; use an extinguisher blanket or foam extinguisher.
Overheated fats and oils may spontaneously ignite. Appliances must never be left unattended
when in operation.
Serious crushing and knocks
yDanger of slipping: remove fat which has splashed onto the oor immediately.

3.2.4 Installing the gas hob
 First of all install the gas hob into the hole at the
rear ①, pressing the clips in slightly when doing
so ②.
 Install the gas hob into the hole at the front ③,
pressing the clips in slightly when doing so ②.
 Check to ensure that the gas hob is ush with the
worktop, that it cannot be moved about freely and
that the hob sealant has been properly applied.
If the gas hob can be moved about freely in the hole,
it will be too big. It can be adjusted slightly with the
clips.
 Push against the gas hob from below and
remove it.
 Bend the clips further outwards.
 Install the gas hob again.
 Install the burner caps.
 Put the saucepan supports in place so that the
pins are in the holes ④.

3.3 Connecting the gas hob
yElectrical connection: connect the mains plug of the appliance to a socket with an earthed conductor.
yGas connection:
○The gas connection must be made by a professional gas tter.
○Observe local gas suppliers’ regulations.
○Observe regulations concerning permissible types of gas; see marking on the back of the
appliance.
○Check the inlet pressure (ow pressure) and ue gas evacuation.
○Check the gas connection, supplies lines and connections to make sure there are no leaks. The
appliance connection may only be checked at a maximum pressure of 150 mbar. Do not operate
any valves while carrying out the check.
○When pipes and hose assemblies are installed it must be ensured that they cannot make contact
with the movable parts of the built-in module, e.g. drawers, nor may they be laid through spaces
in cupboards which may be lled. The connecting hose may not be subject to tensile or torsional
stress, not may it be crushed or tightly bent. The hose connection may not be pushed onto sharp
edges or cutting bodies, it must run freely.

3.4 Operation
The appliance is only intended to be used for cooking food.
WARNING
Fatal injury caused by explosive gas
A smell of gas means that there is a risk of explosion:
yDO NOT ignite gas hobs or electrical switches.
yImmediately close gas shut off valves.
yOpen windows and doors.
yHave a gas tter nd out the cause and rectify it.
yIf a burner goes off during operation, immediately turn the control knob to position “●” ①.
yWait at least one minute before re-igniting.
yNever operate the ignition device for longer than 15 seconds.
Fatal injury caused by ue gases
yThe use of a gas cooker causes heat, humidity and combustion products to form in the
room where the cooker is installed. The room in which the cooker is installed must be
well-ventilated, particularly when the cooker is being used. The natural ventilation openings
must be kept open or a mechanical ventilation device, e.g. a cooker hood, must be installed.
yIntensive and prolonged use of the appliance may require additional ventilation, e.g. an open
window, or effective ventilation, e.g. operation of the mechanical ventilation device at a higher
setting.
Fatal injury caused by re
yDo not allow food to cook until pots and pans are dry.
yDo not switch the burners on if not using them for cooking.
yOnly switch the burners on to cook food; do not, for example, use them to heat rooms.
yKeep combustible materials, e.g. plastics, sheeting, sugar and food containing sugar away
from hot hobs.
yMake sure connection cables for electrical devices are not jammed on the hot burners.
IMPORTANT
yNever use a glass ceramic hob as a work or storage surface! If the glass ceramic surface shows any
signs of cracks, ssures or breakage, switch off the appliance immediately and inform Customer Service
(see the last page for the address).
yDo not use any other spacers on the saucepan supports.
