INSTALLATION MANUAL
1 - WARNINGS AND SAFETY
The boilers produced in our plants are built with great attention to
detail and every component is checked in order to protect users
and installers 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 said conductor.
This instruction manual, together with the user manual, are integral
parts of the product: make sure it remains 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 opera-
tions must be carried out by qualified personnel according to the
provisions of the legislation in force.
The installer must instruct the user about the operation of the ap-
pliance 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 li-
ability 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 contents are in good
condition and complete. Otherwise, contact the dealer from whom
you purchased the appliance.
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.
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 operation carried out on the safety valve.
Dispose of all the packaging materials in the suitable containers at
the corresponding collection centres.
Dispose of waste by being careful not to harm human health and
without employing procedures or methods which may damage the
environment.
During installation, inform the user to:
- in the event of water leaks, the water supply must be shut off and
the Technical Assistance Service must be contacted immediately.
- i t is necessary to periodically check that the operating pressure of
the hydraulic system is above 1 bar. If necessary, reset the pres-
sure as indicated in the paragraph entitled "Filling the system"
- if the boiler is not used for a long time, the following operations
are recommended:
- turn the main switch of the appliance and the main switch of the
system to the "off" position
- close the fuel and water taps of the heating system
- drain the heating system to prevent freezing.
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 main gas tap; contact the Technical Assistance Service or
professionally qualified personnel immediately
do not touch the boiler while barefoot, or if parts of your body are
wet or damp
before any cleaning operations, disconnect the boiler from the
mains power supply by turning the two-position system switch and
the main control panel switch to the "OFF" position
do not modify safety and adjustment devices without the manufac-
turer'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 mains power supply
avoid covering or reducing the size of the ventilation openings in
the installation room
do not leave inflammable containers and substances in the instal-
lation room
keep packaging materials out of the reach of children
it is forbidden to obstruct the condensate drainage point.

2 - DESCRIPTION
Caldariello Condens KIS is a Type C wall-mounted condensing boiler
designed for heating and production of domestic hot water: according to
the flue gas discharge device, the boiler is classified in categories B23P,
B53P, C13,C13x; C23 (where required); C33,C33x; C43,C43x; C53,C53x;
C63,C63x; C83,C83x; C93,C93x.
In configuration B23P and B53P (when installed indoors), the appliance
cannot be installed in bedrooms, bathrooms, showers or where there are
open fireplaces without a proper air flow. The room where the boiler is
installed must have proper ventilation.
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

3.1 - Installation regulations

Installation must be carried out by qualified personnel, in accordance with
local regulations.
POSITION
The boiler has protection that guarantees correct operation with a tem-
perature range from 0°C to 60°C.
To take advantage of protective devices, the appliance must be able to
start up, since any lockout condition (for example, absence of gas or elec-
trical supply, or safety operation) deactivates the protective devices. If the
machine is left powered down for long periods in areas where tempera-
tures may fall below 0°C, and you do not want to drain the heating system,
you are advised to add a good quality antifreeze liquid to the primary circuit
to protect it from freezing.
Carefully follow the manufacturer's instructions with regards not only the
percentage of antifreeze liquid to be used for the minimum temperature
at which you want to keep the machine circuit, but also the duration and
disposal of the liquid itself. For the domestic hot water part, we recommend
you drain the circuit.
The boiler component materials are resistant to ethylene glycol based an-
tifreeze liquids.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance op-
erations, respect the minimum clearances foreseen for installation (fig. 9).
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 all system piping carefully in order to remove any
residues that may impair the operation of the appliance.
Connect the drain manifold to a suitable drainage system (for details, refer
to chapter 3.5). 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 packaging and the adhesive label indi-
cating 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.
3.2 Cleaning the system and characteristics of the
heating circuit water
In the case of a new installation or replacement of the boiler, it is necessary
to clean the heating system.
To ensure the device works well, top up the additives and/or chemical
treatments (e.g. antifreeze liquids, filming agents, etc.) and check the pa-
rameters in the table are within the values indicated.
