CIAO GREEN R.S.I.

- insert the analyser probe in the ports provided in the air distribution box,

after removing the screws from the cover (

g. 40)

- 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 re

t the housing

The

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 ef

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 speci

ca-

tions.

Any cause of visible deterioration must be immediately identi

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 speci

cation.

Any loss in performance must be identi

ed and corrected by

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

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

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

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.
