COMMISSIONING
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 minum power has
been changed, it is necessary repet the adjusting at maximum
gas flow.
Operation 5 - Ending the adjustment
Exit cleaning mode by pressing RESET.
Stop the draw-off.
Verify and repair any leaks of gas.
Refit the front panel to the device.
Refit the blanking cover at combustion test point.

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% (“100” 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 below. (See page 40 for
more details).
Checking slow ignition power
The soft light can be adjusted between the maximum power
(shown on the display as “100”, i.e. 100%) and the minimum
power (shown on the display as “1”, i.e. 1%).
To check the slow ignition power, access menu 2/sub menu 2/
parameter 0.
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
