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 burner has a thermal protection device that
prevents unburned gas from escaping in the open
position.
The total rated thermal load amounts to:
17 000 BTU (5.0 kW) referred to H
s
* (gross calorific
value)
15 300 BTU (4.5 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).
The symbols on the control panel mean:
0 Off
Outer flame ring off
Low position of inner flame ring
