This procedure can also be used to adjust the quantity of
CO
2
to the
ignition power
and to the
minimum power
by pressing
after point 5 of the procedure described above.
• After saving the new value (point 5 of the procedure), press
to take the boiler to its
ignition power
. Wait for the value of
CO
2
to stabilise and then adjust as described in point 4 of the procedure (the power value is a number <> 100 and <> 0) then
save (point 5).
• press
again to take the boiler to
minimum power
. Wait for the value of
CO
2
to stabilise and then adjust as described in
point 4 of the procedure (power value = 00);
• to exit the function, press the buttons for at least 6 seconds as described in point 1.
13. GAS VALVE
This appliance does not require any mechanical adjustment on the valve. The system ensures electronic auto-adaptation.

13.1 GAS CONVERSION METHODS
Only an Authorised Technical Assistance Service can convert boiler operation from
NATURAL GAS
to
LPG
or vice-versa. To
perform calibration, set parameter
P02
as described in the PARAMETER SETTINGS section. Lastly, check the combustion pa-
rameters as described in the SPECIAL FUNCTIONS - CHECKING COMBUSTION PARAMETERS section.
When the gas change is complited the boiler data plate must be amended to indicate the new gas data.
14. PARAMETERS SETTING
To programme the parameters of the boiler electronic board, proceed as follows:
• Press
and
together and hold them down for 6 seconds until programme row “

” appears on the display alternated
with the set value;
• Press
to scroll the list of parameters;
• Press
the value of the selected begins flashing, press
to change the value;
• Press
to confirm the value or press
