Adaptation to different types of gas

IMPORTANT
The replacement/conversion of the gas hob
should only be undertaken by qualified
personnel.
It is important to note that this model is designed for use
with natural gas G20 at a feeding pressure of 20 mbar
but can be converted for use with G30/G31, providing
the correct injectors are fitted. The gas rate is adjusted
to suit.
The oven burner does not need any primary
air regulation.

3. With a socket spanner 7 unscrew and remove the
gas burner injector ("D"), and replace it with the
