Service manual
After measuring the CO2 value at maximum power
switch the units to low power (
Lo
,
Lo1
;
Lo2
).
The upper display shows
CO2
.
Turn the lower knob to
Lo
,
Lo1
or
Lo2
and press
the FLEXI button to activate the low power mode. If
the FLEXI button is not pressed within 5 seconds
the prior mode is still active.
The lower displays shows
Lo
,
Lo1
or
Lo2
.
The rpm´s of the gas blower shows the values
according to the rpm table.
The CO2 content at low power has to be 0,5-1% lower than at high power. This is for a safe operation
of the appliance crucial. The CO content has to be always lower than 100 ppm (Except during the
ignition phase), otherwise the appliance is not allowed to operate. On the two chamber models the
chambers are calibrated separately and can be toggled by turning the lower knob until the desired
chamber and power is displayed. Then press the FLEXI button for confirmation.
The upper chamber is active when
Hi1
or
Lo1
is displayed and the lower chamber is active when
Hi2
or
Lo2
is displayed. Be sure to have the CO2 probe in the correct exhaust pipe.
Changing lower power CO
2
values
If the measured value differs from the values given in
the table, the CO
2
content must be adjusted to match
the values given in the restrictor table. The unit was
designed in that way that the CO
2
values at high
power are automatically within the range. If this is not
the case the installed orifice is wrong or the caloric
heat value of the gas is not normal. With the
adjustment screw [1] the CO
2
for high power can be
influenced.
Unscrew the cap [1] on the gas valve and adjust the
CO
2
content using the adjustment screw (white
plastic) behind it during low power operation. Refit the
metal cab after calibration is finished.
If the low power CO
2
value has been changed, the
CO
2
values at high power has to be checked again.
If the CO
2
content at high power is too high or too low
please check that the correct orifice is installed. The
CO
2
content at high power can be reduced by using
the adjustment screw [2]. It has to be turned inwards
to reduce the CO
2
at high power.
