Operation 4 - Checking the CO2 at minimum output
Whit the Cleaning function active,
press the
button to select
(Minimum Power)
Wait 1 minute for the boiler to
stabilise before carrying out the
combustion analysis.
If the CO2 value (%) read differs by 0.5 % from the value found
whilst adjusting the maximum gas fl ow, then adjust the gas
valve following the instructions below, otherwise move directly
onto operation 5.
Adjusting the gas at minimum output
Remove cap and adjust screw
2
by turning anti-clockwise in
increments to reduce the
CO2 level. Wait 1 minute
after each adjustment for
the CO2 value to stabilise.
WARNING! this adjustment
is sensitive: a rotation of a
1/4 turn corresponds to
0.4% of CO2.
If the value measured
corresponds to the
value given in the table,
adjustment is complete,
otherwise start the setting
procedure again.
Attention! If the value of the CO2 at the minimum power
has been changed, it is necessary repeat the adjustment at
maximum power also.
Operation 5 - Ending the adjustment
Exit the TEST mode by pressing RESET.
Stop the draw-off.
Verify and repair any gas leaks.
Refi t the front panel to the boiler.
Refi t the blanking cover for the combustion test points.

4.5.1 Maximum Heating Power adjustment
The maximum heating power can be adjusted to between
the maximum power allowed by the boiler and the minimum
power).
The display shows the value between 100% (“99” on the display)
and 0% (“0”) of this interval.
To check the maximum heating power, access menu 2/sub
menu 3/parameter 1, check the value and, if necessary, modify
it as indicated in the Gas Regulation table. (See page 36 for
more details).
4.5.2 Checking the soft ignition power
The soft light can be adjusted between the maximum power
(shown on the display as “99”, i.e. 100%) and the minimum
power (shown on the display as “1”, i.e. 1%).
To check the soft ignition power, access menu 2/sub menu 2/
parameter 0.
4.5.3 Heating ignition delay adjustment
This parameter – menu 2/sub menu 3/parameter 5 - can be
used to manually (0) or automatically (1) set the delay time
before the subsequent reignition of the burner after it has
switched off on reaching the desired temperature in central
heating mode.
By selecting manual, it is possible to set the delay in minutes
using the successive parameter (menu 2/sub menu 3/
parameter 6), to a time between 0 and 7 minutes.
Automatic selection means that the boiler will establish the
delay time based on the set-point temperature
