The new built-in glass ceramic gas hobs with open burners:
♦Modern look thanks to “Hardline” design
♦The burners integrated in the glass ceramic surface heat up less which results in a considerably
longer life.
♦The glass ceramic surface does not get hot. It is especially easy to clean as food that might boil over
cannot get burnt.
♦The electric one-hand spark ignition and the high-precision regulation of the individual cooking
zones offer maximum user convenience.

2. Installation Conditions and Assembly
2.1 Notes regarding Installation
♦The room where the appliance is installed should have a volume of at least 20m3and it must be
possible to ventilate it by a window or a door opening out into the fresh air.
♦The hob is built into an opening in the worktop. This opening must be prepared according to the
installation dimensions specified below.
♦The worktop must be aligned horizontally. Make a clean cut into it for the opening.
♦There must be no cross bars beneath the opening. They should be cut back to at least the size of
the opening in the worktop.
♦The distances at the front, rear and sides of the hob opening must conform to the measurements
shown in the drawing. The edges at the front and the rear are based on a worktop depth of 600mm.
The rear edge will be wider for worktops with a greater depth.
♦We recommend protecting the cut surfaces of the worktop opening with a coat of waterproof paint.
♦To ensure ease of operation at the hob, tall cupboards at the side should be at least 300mm away.
♦The air for the burner is supplied through ventilation slits at the back of the control panel.
♦Additional space for the gas connection is required below the hob.
♦The wall connection strip must be made of heat-resistant material and must have no sockets in the
area around the hob. We recommend using a support strip made of plastic with a covering strip
made of aluminium. The lateral part on the worktop must not be longer than 30mm.
♦The wall above the wall connection strip in the area around the appliance must be made of non-
inflammable material. Wood, plastic, PVC foil etc. are not suitable.
♦In normal use very high temperatures may act on the surrounding items of furniture. The plastic finish
or the veneer of built-in kitchen furniture must be protected by a heat-resistant adhesive (100°C).
♦Cooker hoods and wall cupboards above the hob must be installed at a minimum distance of
650 mm.
♦Before installing the hob and any time that the hob is removed, the gasket should be checked for
signs of damage and to ensure that it fits perfectly. Fit a new gasket if necessary. Do not use any
additional adhesives such as silicone, as there is a danger that plastic-coated worktops could be
damaged when the hob is removed.
♦Exception: Uneven worktops (e.g. worktops with ceramic tiles) require a gasket made of a heat-
resistant, permanently elastic sealing material (e.g. with silicone, suitable for ceramic surfaces).
Only apply this sealing material around the edge of the hob, never underneath it!

2.2 Assembly
KÜPPERSBUSCH built-in hobs can and may be exclusivley combined with KÜPPERSBUSCH built-in
ovens with appliance ventilation. The use of other brands excludes any liability by KÜPPERSBUSCH.
The granted test marks and approvals become void in the case of disregarding of this instruction!

2.4 Installation
Using clips makes it easier and quicker for you to install these units. You can carry out the complete
installation work from above.
♦First of all make a clean cut into the worktop observing the indicated dimensions (see “Installation
Dimensions”).
♦Make sure that the gasket of the hob is properly seated. If the worktops are uneven (tiles etc.), you
must also apply a temperature-resistant sealing mass around the edge of the hob.
♦Do not apply the sealing mass underneath the hob onto the worktop as the work surface will be
damaged when the hob is removed.
♦Now convert the hob - if necessary - to a different type of gas.
♦Then insert the clips on the cooking area worktop cut-out as shown in the figures on the previous
page, observing the clearances indicated.
The clips are screwed in different heigth to the hob, according to the thickness of the worktop (30 or 40 mm).

For internal use only
Insert the rear edge of the hob and carefully lower it. At the same time press in the clips with both hands.
Press hob downwards until it rests completely on the worktop.
If the worktop cut-out should be a little too large, it is possible to increase the preliminary spring tension
of the clips by screwing them down.
In case several hobs are installed next to each other the minimum distances indicated in the following
drawing have to be observed.
