3 INSTALLATION

3.1 Cleaning the system and characteristics of 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. anti-freeze liquids, filming agents,
etc.) and check the parameters in the table are within the values indicated.

The boiler must be connected to a heating system and a DHW system,
both sized on the basis of its performance and power.
Before installation, wash every system piping carefully in order to remo-
ve any residues that may impair the operation of the appliance.
Under the safety valve, install a water collecting funnel with the
corresponding 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.
b
Prior to ignition, make sure that the boiler is designed to operate
with the gas available; this can be checked by the wording on the
packaging and by the adhesive label indicating the gas type.
b
It is very important to highlight that in some cases the flues are un-
der pressure, so the joints of the various elements must be airtight.
3.2 Installation regulations
The installation must be carried out by qualified personnel, in compliance
with the following reference standards: UNI 7129-7131 and CEI 64-8.
b
During boiler installation the use of protective clothing is
recommended, in order to avoid personal injury.
Always comply with local standards of the Fire Department, the Gas
Company and with possible municipal dispositions.
POSITION
This type C condensation boiler is designed for heating and domestic
hot water production. There are two categories, depending on the type
of installation:
1. B23P-B53P boiler type - forced open installation, with flue gas discharge
pipe and pickup of combustion air from the installation area. If the boiler
is not installed outdoors, air intake in the installation area is compulsory;
2. C(10); C13,C13x; C33,C33x; C43,C43x; C53,C53x; C63,C63x;
C83,C83x, C93,C93x boiler type: appliance with airtight chamber, with
flue gas discharge pipe and pick-up of combustion air from outside. It
does not require an air intake point in the installation area.
The appliance can be installed indoors (fig. A) or outdoors (but in a par-
tially protected place (fig. B) where it is not directly exposed to rain, snow
or hail). It can work within a temperature range from >0°C to +60°C.
START 25 KIS can also be installed outdoors, in the specific flush-mount-
ing unit (fig. C - the dedicated instructions are supplied with the specific kit).

ANTI-FREEZE SYSTEM
The boiler is fitted as standard with an automatic anti-freeze system that
activates when the temperature of the water in the primary circuit falls
below 5°C. This system is always active, and provides protection for the
boiler up to an air temperature of >0°C in the installation area.
b
To take advantage of this protection (based on burner operation), the boi-
ler must be able to switch itself on; any lockout condition (for ex. due to
a lack of gas or electrical supply, or the intervention of a safety device)
therefore deactivates the protection .
If the machine is left without power for long periods in areas where tem-
peratures may fall below >0°C, and you do not want to drain the heating
system, you are advised to add a good quality anti-freeze liquid to the
primary circuit to protect the machine. Carefully follow the manufactur-
er's instructions with regards not only the percentage of anti-freeze 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 hot domestic water part, we recommend you drain the circuit.
The boiler component materials are resistant to ethylene glycol based
antifreeze liquids.
When the boiler is installed in a place with danger of freezing, with external
air temperatures below >0°C, an antifreeze heater kit must be used to
protect the domestic hot water circuit and condensate drain - available on
request - (see Product catalogue), which protects the boiler down to -15°C.
b
The assembly of the antifreeze heater kit must be carried out only
by authorized personnel, following the instructions contained in the
kit package.
MINIMUM DISTANCES
To ensure access to the boiler for normal maintenance operations, re-
spect the minimum installation clearances envisaged.
For correct appliance positioning, bear in mind that:
- it must be installed on a wall that can support its weight
- it must not be placed above a cooker or other cooking device
- it is forbidden to leave inflammable products in the room where the
boiler is installed
- heat-sensitive walls (e.g. wooden walls) must be protected with proper
insulation.

3.3 Instruction for condensation exhaust connection
This product is designed to prevent the escape of gaseous products of
combustion through the condensation drain pipe with which it is equipped,
this is obtained by using a special siphon placed inside the appliance.
b
All components of the product condensation drain system must
be properly maintained in accordance with the manufacturer
instructions and cannot be modified in any way.
The condensation exhaust system downstream of the appliance must
comply with the relevant legislation and standards.
The construction of the condensation exhaust system downstream of the
appliance is the responsibility of the installer.
The condensation exhaust system must be dimensioned and installed in
such a way as to guarantee the correct evacuation of the condensation
produced by the appliance and/or collected by the evacuation systems
of combustion products.
All the components of the condensation exhaust system must be made in
a workmanlike manner using materials that are suitable for withstanding
the mechanical, thermal and chemical stresses of the condensation
produced by the appliance over time.
Note: if the condensation exhaust system is exposed to the risk of frost,
always provide an adequate level of insulation of the pipe and consider
any increase in the diameter of the pipe itself.
The condensation exhaust pipe must always have an adequate slope
level to prevent the condensation from stagnating and its proper drainage.
The condensation exhaust system must have an inspectable
disconnection between the condensation exhaust pipe of the appliance
and the condensation exhaust system.
