4. Handling
The laboratory burner does not have a closed
position!
The flame of the Bijou 90 can be preselected
by means of the gas lever. The play in the
control elements is intentional. It results from
the prescribed decoupling of valve and control
element.
This guarantees that the valve is always activat-
ed under identical conditions, which is essential
for operational safety.
A
Position A:
Ignition or pilot flame burns
Position B:
Main flame and ignition flame burn
Position C:
Main flame burns
When selecting positions A and C the gas lever
must always be moved all the way to the limit
stop so that, firstly, the position is quickly and
unambiguously identifiable if the burner goes
out and, secondly, to prevent any possibility of
flashback to the burner's jet.

4.1 Regulating the main flame
The burner's main flame can be regulated by
simply turning the knurled ring on the main
burner tube.
A smooth flame is produced by turning the
knurled ring upwards. The air feed is reduced
and the flame becomes smooth.
A harsh flame is produced by turning the
knurled ring downwards. The air feed is in-
creased and the flame becomes harsh.
4.2 Regulating the pilot flame
A smooth flame, which burns very stably, is
produced by pushing the sleeve over the air-
feed holes of the small burner tube.
A harsh flame, which is, however, more
easily extinguished, is produced by pushing the
sleeve away from the air-feed holes of the small
burner tube.
The ignition flame should be as stable, and
therefore as smooth, as possible in order
to ensure reliable burner operation. Adjust
the flame so that it cannot be extinguished
unintentionally.
4.3 Adjusting the burner position
The burner can be positioned at three different
angles:
To adjust the burner to the angle which suits
you best, simply lift it out of its base and
reinsert in the required position. The burner
is thus equally well suited for left-handed and
right-handed users.
The burner should not be used in the
90° position when working with wax,
since dripping wax may block the
jets and cause the burner to mal-
function.
