Changing the gas burner nozzle in the gas burner
i
The nozzles regulate the maximum gas throughflow for
each burner and gas type/pressure.
i
The gas cooktop is set by default to natural gas
G20/20mbar (pre-assembled).
i
Special setting for Australia and New Zealand:
The gas cooktop is set by default to natural gas/ 1.0 kPa
(G20/10mbar pre assembled).
i
Use only stamped and approved nozzles.
The stamp on the nozzles corresponds to the values in the
nozzle table and can be found either on the top or side of the
nozzles.
