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

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

8.4.1

Checking the smoke duct

It is recommended that the user checks that the smoke outlet
duct is integral and airtight.
8.4.2

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 sec-
tion "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
measure the combustion efficiency
– refit the front panel securing it with the two screws which
were removed previously

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.
tS 0.1
tS 0.2
Fig. 52
tS 0.3
tS 0.4
To enter "Parameter setting and display"refer to the indica-
tions 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 re-
placed, the user must still carry out the entire phase of "Auto-
matic calibration procedure" described in the specific section.

Solution
- Contact the Technical Assis-
tance Centre
- Restore pressure
- Check for any leaks in the
system
- Check connections
- Check the sensor is working
- Check connections
- Check the sensor is working
- Check the integrity of the
electrode and check that it is
not grounded
- Check gas availability and
pressure
- Check the integrity of the gas
valve and the card
- Check the sensor or thermo-
stat connections
- Deaerate the system
- Check the bleed valve
- Replace the sensor or the
thermostat
- Check that the pump impeller
is not blocked
- Check the integrity of the
electrode and check that it is
not grounded
- Check the integrity of the gas
valve and the card
- Check the rotation of the pump
rotor
- Check the electrical connec-
tions
- Replace the pump
