If the value lies beyond the
indicated range, make adjustments
with the CO
2
regulating screw at
the Venturi tube.
- When tightening, the gas flow
rate is reduced and the CO
2
value along with it
- When loosening, the CO
2
value
increases.
Then set the burner to "minimum
output" by pressing the reset
button again and holding it for 2-3
seconds.
The "minimum output" mode is
displayed by two quick flashes of
the green LED.
Wait until the minimum output at
the burner has stabilised and check
that the CO
2
value is the same or
slightly below the CO
2
value of
the high flow rate (up to -0.3%).
With deviating values, use the
offset screw.
To change the values, pull out the
metal plug and use the regulating
screw:
- When loosening, the CO
2
value
is reduced.
- When tightening, it increases.
After any changes to the offset
regulation the CO
2
value at high
output must be checked again
through the steps indicated above.
After these steps, set the burner to
"Normal" operation by pressing
the reset button again and holding
it for 2-3 seconds.
This mode is displayed through
the continuous illumination of the
green LED.
After completion of all steps for
the initial commissioning, the user
is instructed in the use of the unit
and its regulation.
If the unit is not set to
"Normal" operation, the
control PCB automatically
resets the unit after 20
minutes.

If the unit should not be used
for extended periods of time,
the gas cocks must be closed
and the main switch of the
unit must be switched off.
ATTENTION
If the unit is not set to "Normal"
operation, the control PCB
automatically resets the unit after
20 minutes.
This also happens if the power
supply of the unit is switched off
and then on again.
ATTENTION
The input of the Venturi tube
may in no case be covered
with your hands or other
objects.
This can lead to flashback of
the premix burner.
The unit always conducts a
follow-up ventilation prior to
switching off the fans.
NOTE
We reserve the right to modify the dimensions and constructional design as part of the ongoing technical development process.
