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 re-
gulated 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 increased 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 pro-
duced by pushing the sleeve away
from the air-feed holes of the small
burner tube.
The ignition flame should be as
C
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:
60
o
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
wor-king with wax, since
dripping wax may block the
jets and cause the burner to
malfunc-tion.
