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

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
