2.3 Operating principle
The appliance features one-hand operation. That
is to say, the ignition is activated when the control
knob is pressed briefly.
After igniting, keep the control knob pressed for
around 5-8 seconds more because the heat sensor
that opens the gas channel has to warm up first.
The gas hob has 2 normal burners and 2 high-
intensity burners.
All burners have a thermal protection device that
prevents unburned gas from escaping in the open
position.
The total rated thermal load amounts to:
32 000 BTU (9.4 kW) referred to H
s
* (gross calorific
value)
28 600 BTU (8.4 kW) referred to H
i
(calorific value)
The specified rated load is defined by installation
of the fixed nozzles.
The gas hob is converted to a different gas
type by nozzle replacement (full and low-burning
nozzles) (see nozzle table on page 12).
The symbols on the control panel mean:
