4.4.4 Special assembly instructions for gas
cooktop CKG
X
X
Please note the local regulations and connection requirements
applicable to gas cooktops.
X
X
Before connecting the appliance, check that the appliance
settings comply with local connection requirements
(gas type and pressure).
i
Minimum requirement for operating gas cooktop CKG:
System software 03.00 (or higher)
X
X
If necessary, retrieve the installed software version
(see operating instructions, Menu chapter, Retrieving the
software version).
X
X
Update the system software if necessary (see operating
instructions, Menu chapter, Updating the system software).
i
Minimum clearance of 650 mm between the worktop and
wall unit in the case of gas devices.
i
On recirculation systems, a return flow aperture of at
least 1,000 cm² must be provided for each air cleaning
unit.
i
Ensure sufficient ventilation.
i
Taking into account the applicable valid regulations,
the cooktop must be connected to the gas line with an
upstream stopcock.
i
The gas supply pipe can be connected after the gas
cooktop has been installed.
i
The hose connection must be laid in such a way that it is
not subject to deformation, buckling or abrasion.
i
The stopcock and gas supply pipe connections must be
accessible.
i
It must be possible to inspect the entire length of the
hose line once installed.
i
Only compatible connection pieces are to be used for the
hose line.
i
The pressure regulator must correspond to the set gas
type and set gas pressure and must meet local and legal
requirements.
i
The gas connection hose line must not come into contact
with smoke or the flue outlet of an oven.
i
The hose line must not come into contact with hot
surfaces on the cooktop or other devices.
i
The gas hose must be inspected every 5 years and
replaced if necessary. The gas hose must meet the
requirements of EN14800.
4.4.3 Recirculation when using the cooktop
extractor as a recirculation system
In the case of recirculation systems there must be a return flow
aperture in the kitchen units:
X
O
> 500 cm² (per air cleaning box) in combination with cooktops
CKFI, CKI, CKIW, CKCH, CKCB and CKT
X
O
> 1000 cm² (per air cleaning box) in combination with gas
cooktop CKG
i
If several extractor systems are operated in recirculation
mode, the return flow aperture for each air cleaning box
must be calculated correspondingly. Example:
2 recirculation systems = 2 x (> 500 cm²) or
2 x (> 1,000 cm²) in the case of gas appliances
For recirculation, the necessary return flow aperture can be
created using a shortened plinth. A slatted plinth with at least
the minimum opening cross-section can also be used.
X
X
Ensure that the return flow aperture is large enough.

i
If the gas flame goes out, is excessively affected by the
extractor and/or the flame is not as it should be (e.g.
soot production, flame blowback, etc.), the return flow
aperture must be enlarged.
