To identify the burners on your hob, please refer to the illustrations in paragraph
“10.7 Arrangement of the burners on the hob”.
If having adjusted the air the flame appears as illustrated in the figure:
the following modifications must be made:
A: the flame is "noisy", unstable or "detaches" from the burner: the primary air is
too high.
B: The flame is opaque, dull or has yellow tips and "wraps around" the burner:
the primary air is too low.
C: The flame is blue, clear and stable, does not "detach" or "wrap around" the
burner: the air is adjusted correctly.
