First air regulation
First air regulation may be necessary to always
achieve a stable and low-noise flame in the event of
deviating gas types and pressures.

After undoing the screw 2 (7 mm), move the air
regulation sleeve 1 in the direction of the nozzle 3
or away from the nozzle up to a maximum distance
of 12 mm until the flames burn stably and with low
noise. Yellow tips must not be visible in the flames.
The flame must not go off when you switch swiftly
from the high to the low setting. Firmly screw in the
screw 2 again.
