If the value is outside the specified
range, readjust with the CO2
regulating screw on the Venturi
tube.
- When the screw is tightened,
the gas flow rate decreases as
does the CO2 value.
- The CO2 value increases when
the screw is unscrewed.
Subsequently set the burner to
“minimum output” by pressing
and holding the rest button again
for 2 to 3 seconds.
Operation at “minimum output” is
indicated by the green LED rapidly
flashing twice.
Wait until the minimum output
at the burner has stabilised and
check that the CO2 value is equal
to or slightly below the CO2 value
at the maximum flow rate ( up to
-0.3%).
A deviating value can be corrected
with the offset screw.
To make changes to values,
remove the metal plug and turn
the regulating screw:
- the CO2 value decreases when
the screw is unscrewed,
- the CO2 value increases when
the screw is tightened.
After making any adjustments with
the offset regulating screw, the
CO2 value at maximum output
must be rechecked by carrying out
the above described steps.
After carrying out these steps,
set the burner to “normal” mode
by pressing and holding the reset
button again for 2 to 3 seconds.
This mode is indicated by the
green LED showing a steady light.
If the unit is not set to
“normal mode“, the control
board will automatically reset
the unit after 20 minutes.

If the unit is not used for a
prolonged period, the gas
valves must be closed and
the main switch of the unit
switched off.
ATTENTION
ATTENTION
The entrance of the Venturi
tube must under no
circumstances be covered by
the hands or other objects.
This can lead to flashback of
the premixing burner.
The unit performs a cooling
cycle in any event before the
fans are switched off.
NOTE
We reserve the right to make changes to dimensions and design in the interest of technological advances.
After carrying out all steps for
commissioning, the user must be
instructed in the operation of the
unit and its control.
If the unit is not set to “normal”
mode, the control board will
automatically reset the unit after
20 minutes.
This also occurs if the power
supply to the unit is disconnected
and then reconnected.
