5.1 Burner head disassembly and cleaning:
Allow sufficient time for burner orifice (7,7a) to cool
down before disassembling or cleaning the burner
head. Check the unit is turned off, that the gas supply
is turned off at the mains. Clean the burner head with
customary commercial disinfectants, sterilize it in
an autoclave or wash it in a dishwasher. To remove
the burner head proceed as follows:
Unscrew the burner head screw (12) completely with
the included screwdriver. Turn approx. 8 revolutions to the left.
Now remove the burner head from the device by pulling it upwards. Reinstallation is
performed in the reverse sequence. The dismounted burner head can be even dismantled
into the individual components for in-depth cleaning: Unscrew both screws (12a) and take
off the base plate (12b) of the burner head which was fixed by the two screws (12a). After the
base plate is removed both electrodes can be pulled out for seperate cleaning. Reinstallation
is performed in the reverse sequence.
Notice: When dismantling the burner head completely the sealing ring placed around the
burner head screw (12) could dropout. Ensure that the sealing ring is placed around the burner
head screw (12) when reassembling.
5.2 Burner shaft cleaning:
Unscrew the screw (18) completely with the
included screwdriver. Take off the cover (17)
of the burner shaft. Now the burner shaft can
be cleaned or solid substances which have
fallen into the unit can be removed.
Reinstallation is performed in the reverse
sequence. Take care that the notch of the
cover fits to the screw (18a).
6. Turbo flame:
If the cover of the burner shaft (17) is removed
the flame is extremely firm and consistent. To
take off the cover of the burner shaft unscrew
the screw (18) completely with the included screwdriver. With an open burner shaft the
intensity of the flame cannot be adjusted by the air knob any longer. During the use of the turbo
flame most of the needed air is taken inside through the open burner shaft. Remounting the
cover of burner shaft. (see paragraph 5.2)

Nozzle P (06): propane / butane gas, input pressure: 47-57 mbar
LED “Burner head HOT / BHC“ flashes / Inspection of the burner head (clogging)
Take care that there are no liquids or other substances at the Bypass (area between the
inner and the outer ring)
Especially remove substances in the
marked areas at the electrodes. If there
are contaminants in this area, the flame
cannot encircle the electrodes correctly.
Clean this areas with a brush. The
burner head can be cleaned with
customary commercial disinfectants,
or it can be sterilized in an autoclave or
washed in a dishwasher.
In operating mode “Button“ or Pedal “StartStop“ flame burns 30 seconds, only
BHC time limit is active, LED “burner head HOT / BHC“ is flashing. The burner head is
clogged and must be cleaned (see paragraph 3 and 5.1).
Flame too small / large / soft
Check the position of the air and gas adjustment.
Check if the correct nozzle is installed.
Nozzle N (08): natural gas, 18-25 mbar
Nozzle P (06): propane / butane gas, 47-57 mbar
Check if the drilling of the active nozzle is blocked. Unscew the active nozzle.
(see paragraph 1) If the drillig is blocked clean with a brush or compressed air.
No ignition spark / LED “Burner head HOT / BHC“ flashes but the burner head is clean
Check if the ceramic electrodes are in good condition. In some cases the electrodes
may break. To check move the ends of the electrodes. If they are not moving they
should be okay. If they are moving more than 0.5 mm the electrodes are broken. The
electrodes can be dismantled and changed by the user. (see paragraph 5.1)
