After having set the distance of the air
regulator “D”, the flame may appear as
illustrated:
• 1: the flame is “noisy” and “detaches”
from the burner: the air regulator has
been opened too far.
• 2: the flame is opaque, dull or has
yellow tips and “wraps around” the
burner: the air regulator has been closed
too far.
• 3: the flame is light blue, clear and
stable, does not “detach” or “wrap
around” the burner: the air regulator is
adjusted correctly.
If the flame appears as in “1” or “2”, the air
regulator has to be reset according to the
measurements shown in the table “Burner
and nozzle characteristics table”.
