Gas configuration menu item
The burner nozzles, gas type, gas pressure and gas
characteristic curve may only be changed by a certified
engineer or BORA service technician. They also assume
responsibility for the proper gas installation and
commissioning.
It is important that the gas type, gas pressure and
characteristic curve are set correctly to ensure safe, failure-
free operation of the gas cooktop.

Menu item CE: GPU configuration
Under menu item CE (GPU) the minimum power of each burner and
gas type/pressure is regulated.

characteristic curves
You can select the characteristic curves for the gas burners here. The
characteristic curves regulate the minimum gas burner power values.
The minimum power levels are adjusted using the characteristic
curves. Depending on the installation situation and the influence of
the cooktop extractor, if necessary, the characteristic curve can be
changed.
Characteristic curve A:
A enables the fine tuning of the power values, which can only be
adjusted in the best-case scenario and only in the case of natural gas
(G20, G25, G25.3). The best-case scenario is when:
T
no cooktop extractor is in operation; or
T
the cooktop, when using the cooktop extractor in exhaust air
mode, is used with sufficient ventilation; or
T
the cooktop, when using the cooktop extractor in recirculation
mode is used with a sufficient return flow aperture and the cooktop
extractor does not have a negative influence on the gas flame.
Characteristic curve B:
B is the factory default characteristic curve with balanced adjustment
of the individual power levels.
Characteristic curve C:
C increases the lower power levels and should only be used in the
event of a negative influence from the cooktop extractor.
u
Select the appropriate characteristic curve.

Characteristic curves for the gas burner
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 characteristic curve
must be increased, as well as the ventilation in exhaust air
mode, if necessary, or the return flow aperture in recirculation
mode.

Menu item Ch: GPU reset
This menu item provides a reset function. This reset function can be
used in the case of faults and errors and during initial operation if the
gas cooktop does not react (does not ignite). The set values for the
gas type, pressure and characteristic curve remain unchanged and
are not affected by the reset.
u
Perform a reset if necessary.
