the electrical wiring, in particular the stripped part of conduc-
tors, which must not stick out from the terminal board, avoid-
ing possible contact with live parts of such conductor.
This instruction manual, together with the user manual, are
integral parts of the product: make sure that they remain with
the appliance, even if it is transferred to another owner or
user, or moved to another heating system. In case of loss
or damage, please contact your local Technical Assistance
Service for a new copy.
Boiler installation and any other assistance and maintenance
operation must be carried out by quali
fi
ed personnel accord-
ing to current local and national regulations.
The installer must instruct the user about the operation of the
appliance and about essential safety regulations.
This boiler must only be used for the application it was de-
signed for. The manufacturer declines all contractual and
non-contractual liability for injury to persons or animals or
damage to property deriving from errors made during instal-
lation, adjustment and maintenance and from improper use.
After removing the packaging, make sure the content is in
good conditions and complete. Otherwise, contact the dealer
from who you purchased the appliance.
The safety valve outlet must be connected to a suitable col-

out in the safety valve.
Dispose of all the packaging materials in the suitable contain-
ers at the corresponding collection centres.
Dispose of waste being careful not harm human health and
without employing procedures or methods which may dam-
age the environment.
C.A.I. models: the ventilation openings are vital for correct
combustion.
During installation, inform the user that:
- in the event of water leaks, the water supply must be shut off and
the Technical Assistance Service must be contacted immediately
- the operation pressure of the hydraulic system must be within 1
and 2 bar, and therefore, must no exceed 3 bar.If necessary, reset
the pressure as indicated in the paragraph entitled “Filling the
system”
- if the boiler has not been used for a long time, it is recommended
that the Technical Assistance Service performs, at least, the fol-
lowing operations:
• turn “off” the main switch of the appliance and the general
switch of the system
• close the gas and water taps on both the heating and domes-
tic hot water circuits
• drain the heating and domestic hot water circuits to prevent
freezing
- boiler maintenance must be carried out at least once a year. This
should be booked in advance with the Technical Assistance Ser-
vice.
For safety, always remember that:
The boiler should not be used by children or unassisted disabled
people.
It is dangerous to activate electrical devices or appliances,
such as switches, home appliances, etc., if you smell gas or
fumes. In the event of gas leaks, ventilate the room opening
doors and windows; close the gas general tap; contact the
quali
fi
ed personnel from the Technical Assistance Service im-
mediately
Do not touch the boiler while barefoot or if parts of your body
are wet or damp
Before cleaning operations, disconnect the boiler from the
main power supply by turning “OFF” the two position system
switch and the main control panel switch
Do not modify safety and adjustment devices without the
manufacturer's permission and relative instructions
Do not pull, disconnect or twist the electric cables coming
out of the boiler even when it is disconnected from the main
power supply
Avoid covering or reducing the size of ventilation openings of
the installation room
Do not leave in
fl
ammable containers and substances in the
installation room
Keep packaging materials out of reach of children.
C.A.I. models: do not cover or reduce the size of the ventila-
tion openings in the room where the boiler is installed. The
ventilation openings are vital for correct combustion.
2 - BOILER DESCRIPTION
CIAO C.A.I. e
is a wall-mounted type B11BS boiler for heating and
the production of domestic hot water. This type of appliance cannot
be installed in bedrooms, bathrooms or showers, or in rooms with
open
fl
ues without adequate ventilation.
CIAO C.A.I. e
boiler is
fi
tted with the following safety devices:
- Safety valve and water pressure switch intervening in cases of
insuf
fi
cient or excessive water pressure (max 3 bar-min 0.7 bar).
- Temperature limit thermostat intervening by putting the boiler into
safety stop if the temperature in the system exceeds the limit ac-
cording to current local and national regulations
- Fumes thermostat intervenes by blocking the boiler into a safety
standstill status if there is a spillage of combustion products in
the hood; it is located on the right hand tile of the vent-damper
draught breaker device Intervention of safety devices indicates
a potentially dangerous boiler malfunction; contact the technical
assistance service immediately.
The
fl
ue gas thermostat not only intervenes for a fault in the com-
bustion products outlet system, but also with various atmospheric
conditions. One can therefore try to start up the boiler again after
waiting a short while (see
fi
rst ignition section).
Repeated intervention of the fumes thermostat signi
fi
es
evacuation of combustion products into the boiler room with
possibly incomplete combustion and formation of carbon
monoxide,
a highly dangerous condition. Call the techni-
cal assistance service immediately.
The boiler must never be put into service, not even temporar-
ily, if the safety devices are not working or have been mis-
handled.
Safety devices must be replaced by the technical assistance
service, using original manufacturer parts only; see the spare
parts catalogue supplied with the boiler.
After repairs carry out a trial ignition.
