Service Manual GCM 642.0 ME/GES 642.0
For internal use only
If the room where the appliance is installed is limited at the bottom by a horizontal
partition plate, an aeration duct must be created to the surrounding furniture through
an at least 180 cm² (e. g. 10 x 18 cm) large opening in the partition plate.
A space of at least 5 mm must remain between the inside edge of the furniture front
and the worktop recess.
The wall sealing strip must be made of heat-resistant material and must not be
provided with sockets in the hob area. A plastic carrier strip with a cover strip of
aluminium is recommended. The leg length on the worktop must not exceed 30 mm.
As regards protection against overheating of the surrounding areas, the appliance is of
the type Y to VDE 0700/6 and IEC 335-2-6.
The wall above the sealing strip near the appliance must be made of non-flammable
material. Wood, plastic, PVC films etc. do not satisfy this requirement.
In normal use, radiated temperatures of 70°C above room temperature can act on the
surrounding furniture. The furniture must satisfy at least this requirement. In the case
of fitted units the plastic covering or the varnish must be processed with heat-resistant
adhesive (100°C).
The temperature produced at the back of the hob is approx. 300°C. The minimum
distance of wall cupboards and fume extractors above the hob is 650 mm.
Due to the high temperature produced at the back of the hob, the stainless steel grid
becomes bluish. These discolourations can be removed by means of stainless steel
cleaners and are no reason for claims.
