1 - GENERAL SAFETY DEVICES

Our boilers are built in our plants and checked down to the smallest
detail in order to protect users and fitters from injury.After working on
the product, qualified personnel must check the electrical wiring, in
particular the stripped part of conductors, which must not stick out
from the terminal board, avoiding 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.
This boiler may only be installed and serviced by qualified personnel
who comply with the national and local current 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 designed 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 installation, adjustment and maintenance and from
improper use.
After removing the packaging, make sure the content is in good con-
ditions and complete. Otherwise, contact the dealer from who you
purchased the appliance.
The safety valve outlet must be connected to a suitable collection and
venting system. The manufacturer declines all liability for any damage
caused due to any intervention carried out in the safety valve.
The safety valve outlet must be connected to a suitable collection and
venting system. The manufacturer declines all liability for any damage
caused due to any intervention carried out in the safety valve.
Dispose of all the packaging materials in the suitable containers at
the corresponding collection centres.
Dispose of waste being careful not harm human health and without
employing procedures or methods which may damage the environ-
ment.
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, let qualified personnel
from the Technical Assistance Service intervene
- if the boiler has not been used for a long time, it is recommended that
the Technical Assistance Service performs, at least, the following opera-
tions:
• 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 domestic 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 Service.
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 qualified personnel from the
Technical Assistance Service immediately
In some parts of the manual, some symbols are used:
WARNING = for actions requiring special care and adequate prepara-
tion
FORBIDDEN = for actions THAT MUST NOT be performed
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 manufactur-
er'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 inflammable containers and substances in the installation
room
Keep packaging materials out of reach of children.

2 - BOILER DESCRIPTION

Junior 24-28 C.S.I. is a wall-mounted boiler type C for heating and produc-
tion of domestic hot water: according to the flue gas outlet device, the boiler
is classified in categories C12, C22, C32, C42, C52, C62, C82 C12x, C32x,
C42x, C52x, C62x, C82x.
In configuration C, the appliance can be installed in any type of room and
there are no limitations due to ventilation conditions or room volume.

3 - INSTALLATION REGULATIONS

Installation must be carried out by qualified personnel.
Always comply with national and local regulations.
POSITION
Junior 24-28 C.S.I. can be installed indoor (fig. 2).
The boiler has protection that guarantees correct operation with a temperature
range from 0°C to 60°C.
To take advantage of protections, the appliance must be able to start up,
since any lockout condition (for example, absence of gas or electrical supply,
or safety intervention) deactivates the protections.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance opera-
tions, respect the minimum spaces foreseen for installation (fig. 3).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- do not leave inflammable products in the room where the boiler is installed
- heat sensitive walls (for example, wooden walls) must be protected with
proper insulation.
IMPORTANT
Before installation, wash every system piping carefully in order to remove
any residues that may impair the operation of the appliance.
Under the safety valve, install a water collecting funnel with the correspond-
ing discharge in the event of leaks due to the overpressure of the heating
system. The domestic hot water circuit does not need a safety valve, but
make sure that the pressure of waterworks does not exceed 6 bar. In case
of doubts, install a pressure reducer.
Prior to ignition, make sure that the boiler is designed to operate with
the gas available; this can be checked by the message on the packag-
ing and the adhesive label indicating the gas type.
It is very important to highlight that in some cases the smoke pipes are
under pressure and therefore, the connections of several elements must
be airtight.
