This signal indicates that the time limit (30 seconds) is turned on in operating mode “StartStop“

and “Button“ due to a clogged burner head. For cleaning the burner head see paragraph 5.1.

Notice: All error displays can be reset by a long push (2 seconds+) on the function knob (1).

(In case of overtemperature the unit needs to be cooled down and in case of burner head

assembly monitor the burner head needs to be reinstalled prior a reset is possible.)

5. Cleaning and sterilizing:

Allow sufficient time for burner orifice (7, 7a) to cool down before disassembling or cleaning

the burner head. Check the unit is disconnected and that the gas supply is turned off at the

mains. The burner can be cleaned with customary commercial disinfectants. Additionally, it

is possible to remove the burner head and to clean it separately.

The stainless steel and glass construction allow 100% UV-radiation sterilization and short

time surface flame sterilization.

Attention: Because of the connectors at the back of the unit the backside should not be

sterilized with a flame.

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)

7. Tilt adjustment:

Insert the tilt adjustment (23) into the slots (19)

at the bottom of the unit. The tilt-adjustment can

be used to the left or right side to protect the

burning chamber from contamination when

working with liquids.

In case of ignition or flame faliure check if the burner head is clogged. Verify the input

pressure of the used gas. Ensure that the correct nozzle is installed in the unit.

Nozzle N (08): natural gas, input pressure: 18-25 mbar

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)
