- Check the flue combustion.
The "combustion analysis" remains active for a time limit of 15 min;
in the event it is reached in a flow temperature of 90 °C the burner
shutdown.
It will turn back when this temperature falls below 78 °C.
If you wish to stop the process turn the hot water temperature in the
area between the "+" and "-".
Then:
- remove the analyser probe and close the sockets for combustion
analysis with the special screw
- close the instrument panel and refit the housing.
5 MAINTENANCE
The appliance must be systematically controlled at regular inter-
vals to make sure it works correctly and efficiently and conforms to
legislative provisions 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 ev-
ery year.
- Check and compare the boiler's performance with the relative
specifications.
Any cause of visible deterioration must be immediately identified
and eliminated.
- Closely inspect the boiler for signs of damages or deterioration,
particularly with the drainage and aspiration system and electri-
cal apparatus.
- Check and adjust – where necessary – all the burner's param-
eters.
- 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 identified and corrected by find-
ing 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 flammable sub-
stances (e.g. petrol, alcohol, etc.).
Do not clean panelling, enamelled and plastic parts with paint sol-
vents.
Panels must be cleaned with ordinary soap and water only
MAINTENANCE FOR PRESSURISED COLLECTIVE CHIMNEY
(for 25kW)
In the event of maintenance operations on the boiler which
require the flue gas pipes to be disconnected, a cap should be
placed on the open element originating from the pressurised
smoke pipe.
In the event of fan removal check that the non return valve is
properly positioned in the correct side (see pages 179-180).
Failure to adhere to the guidelined provided can compromise
the security of persons and animals due to potential leakages
of carbon monoxide from the smoke pipe.

Boiler installation and any other assistance and maintenance
operation must be carried out by qualified personnel accord-
ing to current local and national regulations.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by
the manufacturer. The manufacturer shall not be liable for
any damage to persons, animals or property due to errors in
installation, calibration, maintenance or due to improper use.
The safety and automatic adjustment devices must not be modi-
fied, during the system life cycle, by the manufacturer or supplier.
This appliance produces hot water, therefore it must be con-
nected to a heating system and/or a domestic hot water
mains, compatible with its performance and output.
In case of water leakage, close the water supply and contact
the Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply
and switch off the electrical supply main switch. In case of risk
of frost, empty the boiler.
From time to time check that the operating pressure of the
hydraulic system does not decrease under 1 bar.
In case of failure and/or malfunctioning, deactivate the appli-
ance, and do not try to repair or intervene directly on it.
Appliance maintenance must be carried out at least once a
year: program it with the Technical Assistance Service will
avoid wasting time and money.
When the product reaches the end of its life it should not be
disposed of as solid urban waste but should be brought to a
separated waste collection facility.
Boiler use requires to strictly observe some basic safety rules:
Do not use the appliance in any manner other than its in-
tended purpose.
It is dangerous to touch the appliance with wet or damp body
parts and/or in bare feet.
Under no circumstances cover the intake grids, dissipation
grids and ventilation vents in the installation room with cloths,
paper or any other material.
Do not activate electrical switches, telephone or any other object
that causes sparks if there is a smell of gas. Ventilate the room
by opening doors and windows and close the gas central tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not
disconnected from the main power supply.
Do not cover or reduce ventilation opening of the room where
the generator is installed.
Do not leave containers and inflammable products in the in-
stallation room.
Do not attempt to repair the appliance in case of failure and/
or malfunctioning.
It is dangerous to pull or twist the electric cables.
Children or unskilled persons must not use the appliance.
Do not intervene on sealed elements.
For better use, remember that:
- a periodic external cleaning with soapy water not only improves
its aesthetic aspect but also preserves panelling from corrosion,
extending its life cycle;
- if the wall-mounted boiler is enclosed in pendant furniture, leave
at least 5 cm for ventilation and maintenance;
- installation of an room thermostat will favour a greater comfort, a
more rational use of the heat and energy saving; the boiler can
also be connected to a programming clock in order to manage
ignition and switching off during the day or week.
