Cleaning the burner

The burner does not require any particular maintenance simply
dust it with a soft brush.
4.3.3

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.
m
CAUTION
The position of the electrode is essential for the correct
detection of current ionization.
4.3.4

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 (4)
of the combustion chamber are integral. If this is not the case
then replace it
– refit the panel (4) secure it with fastening screws.

Checks

4.4.1

Checking the smoke duct

It is recommended that the user checks that the smoke outlet
duct is integral and airtight.
4.4.2

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
sectionExpansion 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
measure the combustion efficiency.
– refit the front panel securing it with the two screws which
were removed previously

If replacing the electronic board , the user MUST set the
parameters as indicated in the table.
Type No. Description
Index showing boiler power in kW
tS 0.1
0 = 24
Hydraulic configuration
0 = rapid
1 = storage tank with thermostat or
tS 0.2 heating only
2 = hot water tank with sensor
3 = bithermic
4=instant with solar power input
Gas Type Configuration
tS 0.3
0 = G20; 1 = G31
Combustion configuration
0 = sealed chamber with combustion
control
tS 0.4
1 = open chamber with smoke
thermostat
2 = low NOx
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
replaced, the user must still carry out the entire phase of "

Automatic calibration procedure" described in the specific
section.
