- re-power the boiler and turn on the gas tap
Adjust the boiler as described in the chapter entitled "Adjustments" with
reference to the information on LPG.
Conversion must be carried out by qualifi ed personnel.
Once the conversion is complete, affi x the new identifi cation
label supplied in the kit.

4.9 Checking the combustion parameters

To carry out the combustion analysis, proceed as follows:
- set the main switch of the installation to the "OFF" position
- loosen the fi xing screws (D) on the housing (fi g. 13)
- move the base of the housing forwards and then upwards to unhook it
from the chassis
- loosen the fi xing screws (E) on the instrument panel (fi g. 14)
- lift then turn the instrument panel towards you
- loosen the fi xing screws on the cover (F) to access the terminal board (fi g. 16)
- using a small screwdriver included, press the CO button (fi g. 26)
Live electrical parts (230 V AC).
- Wait for burner ignition. The display shows "ACO", the yellow LED fl ash-
es and the boiler operates at maximum heat output.
- insert the analyser probe in the ports provided in the air distribution box,
after removing the screws from the cover (fi g. 41)
- check that the CO2 values match those given in the table, if the value
shown is different, change it as indicated in the chapter entitled "Gas
valve calibration".
- perform the combustion check.
Then:
- remove the analyser probe and close the sockets for combustion analy-
sis with the special screw
- close the instrument panel and refi t the housing
The fl ue gas analysis probe must be fully inserted as far as pos-
sible.
IMPORTANT
Even during the combustion analysis phase, the function that switches the
boiler off when the water temperature reaches the maximum limit (about
90°C) remains enabled.

5 MAINTENANCE

The appliance must be systematically controlled at regular intervals to
make sure it works correctly and effi ciently and conforms to legislative pro-
visions in force.
The frequency of controls depends on the conditions of installation and
usage, it being anyhow necessary to have a complete check carried out by
authorized personnel from the Servicing Centre every year.
- Check and compare the boiler's performance with the relative specifi ca-
tions. Any cause of visible deterioration must be immediately identifi ed
and eliminated.
- Closely inspect the boiler for signs of damages or deterioration, particu-
larly with the drainage and aspiration system and electrical apparatus.
- Check and adjust – where necessary – all the burner's parameters.
- Check and adjust – where necessary – the system's pressure.
- Analyze combustion. Compare results with the product's specifi cation.
Any loss in performance must be identifi ed and corrected by fi nding and
eliminating the cause.
- Make sure the main heat exchanger is clean and free of any residuals or
obstruction.
- Check and clean – where necessary – the condensation tray to make
sure it works properly.
IMPORTANT: always switch off the power to the appliance and close the
gas by the gas cock on the boiler before carrying out any maintenance and
cleaning jobs on the boiler.
Do not clean the appliance or any latter part with fl ammable substances
(e.g. petrol, alcohol, etc.).
Do not clean panelling, enamelled and plastic parts with paint solvents.
Panels must be cleaned with ordinary soap and water only.
The fl ame side of the burner is made of state-of-the-art material.
Being fragile:
- be particularly careful when handling, mounting or dismantling the burner
and adjacent components (e.g. electrodes, insulation panelling etc.)
- avoid direct contact with any cleaning appliance (e.g. brushes, aspira-
tors, blowers, etc.).
This component does not need any maintenance, please do not remove it
from its housing, save where the O-ring may have to be replaced.
The manufacturer declines all responsibility in cases of damages due to
failing to observe the above.

MAINTENANCE FOR PRESSURISED COLLECTIVE CHIMNEY (3CEP)
In the event of maintenance operations on the boiler which require the fl ue
gas pipes to be disconnected, a cap should be placed on the open element
originating from the pressurised smoke pipe.
Failure to adhere to the guidelines provided can compromise the security
of persons and animals due to potential leakages of carbon monoxide from
the smoke pipe.
