Run the CO
check procedure as explained in paragraph

"3.17 Combustion check". If the values need to be
modified, proceed as follows:
ƒ check the CO
values with the casing closed
2
ƒ remove the casing as explained in paragraph "2.10
Removing the casing"
ƒ check the CO
values again, with the casing open

ƒ bearing in mind the difference between the values
measured with the casing closed and open, if nec-
essary adjust the CO
to the value shown in the table

ƒ rotate the maximum output adjustment screw clock-
wise to reduce the value, or anti-clockwise to in-
crease it
ƒ rotate the minimum output adjustment screw clock-
wise to increase the value, or anti-clockwise to re-
duce it
ƒ with the casing open, and after adjusting the CO
ue at the minimum output, check the CO

3.20 Gas conversion
It is easy to make the conversion from one gas to another
even after the boiler has been installed. This operation
must be carried out by professionally qualified personnel.
The boiler is designed to operate with methane gas (G20)
according to the product label. It is possible to convert
the boiler to LPG with the aid of the relative kits.
For disassembly refer to instructions below:
ƒ disconnect the boiler from the electricity supply and
turn off the gas tap
ƒ remove the casing as explained in paragraph "2.10
Removing the casing"
ƒ release the instrument panel and rotate it forwards.
ƒ Loosen the nut of the gas train (A).
ƒ Remove the nozzle (B) inside the gas valve, and re-
rpm
place it with the one in the kit.

Conversion must be carried out by qualified per-
sonnel.

After the transformation, apply the new rating
plate included in the kit.
3.21 Signalling and faults
In there is a fault, the
sec OFF). The backlight will flash for 1 min (1 sec ON, 1 sec
OFF) and then switch off, but the bell will carry on flash-
ing. The 4-digit area of the display will show a sliding
message with the error code.

The following icons may appear when a fault arises:
−
lights up for a flame alarm (E010)
− RESET lights up for an alarm that needs to be manually
reset by the user (e.g. a flame lockout)
−
lights up along with the
lockout and water failure faults)
-
In addition, when parameter P3.02 is set with a value of
1, meaning that a water pressure transducer is fitted, the
pressure value is shown when it is higher than 5.0 bar
(excessively high pressure); the boiler carries on working
as these are merely info messages. With pressure lower
than 0.8 bar (excessively low pressure) the boiler stops
functioning. In these cases, the pressure value, with the
relative measurement unit, is also shown at the end of
the following error messages:
