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.
10.5 Adjusting the minimum for natural gas
Reposition the components on the burner and
slide the knobs onto the tap rods.
Light the burner and set it to the minimum
position .
Extract the knob again and turn the adjustment
screw inside or next to the tap rod (depending
on the model) until the correct minimum flame
is achieved.
Refit the knob and verify that the burner flame
is stable (when turning the knob rapidly from
the maximum to the minimum position the
flame must not go out).
