8.4.3 Checking the ignition/detection electrode
Check the state of the ignition/detection electrode and replace if
necessary. Check the measurements as per the drawing whether
the ignition/detection electrode is replaced or not.

CAUTION
The position of the electrode is essential for the correct
detection of current ionization.
8.4.4 Final operations
After having cleaned the heat exchanger and the burner:
– remove any carbon residue using a vacuum cleaner
– check that the gasket and the insulation of the front panel (6) of
the combustion chamber and the gasket (13) of the front panel
(4) of the sealed chamber are all integral. If they are not, replace
them
– refit the panels (6) and (4) securing them with fastening screws.

8.5 Checks
8.5.1 Checking the smoke duct
It is recommended that the user checks that the smoke outlet
duct is integral and airtight.
8.5.2 Checking the expansion vessel pressure
It is recommended that the expansion vessel on the water side is
drained and that the prefilling pressure is not less than
1 bar
. If
this is not the case, pressurize it to the correct value (see section
"Expansion vessel").
Once the checks described above have been completed:
– refill the boiler as described in section "REFILL operations"
– start the boiler up and carry out a smoke analysis and/or mea-
sure the combustion efficiency
– refit the front panel securing it with the two screws which were
removed previously
8.6 Unscheduled maintenance
If replacing the
electronic board
, the user MUST set the parame-
ters as indicated in the table and in the sequence shown.
Type No. Description Setting
tS 0.1
Index showing boiler power in kW
0 = 24; 1 = 28; 2 =40
0 or 1 or 2
tS 0.2
Hydraulic configuration
0 = rapid
1 = storage tank with thermostat or
heating only
2 = hot water tank with sensor
3 = bithermic
4=instant with solar power input
0
tS 0.3
Gas Type Configuration
0 = G20; 1 = G31
0 or 1
tS 0.4
Combustion configuration
0 = sealed chamber with combustion
control
1 = open chamber with smoke thermo-
stat
2 = low NOx
0 or 1
To enter "Parameter setting and display"refer to the indications
provided in the specific section.
Once the parameters in the table have been set, you must carry
out the "Automatic calibration procedure".
If the
gas valve
and/or the
ignition/detection electrode
, are repla-
ced, the user must still carry out the entire phase of "Automatic
calibration procedure" described in the specific section.
