Installation regulations

The installation must be carried out by qualifi ed 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
CIAO AT is a wall-hung boiler for heating and for the production of hot water, that comes in
two categories, depending on the type of installation:
- B22P-B52P boiler type - forced open installation, with fl ue gas discharge pipe and pick-
up of combustion air from the installation area. If the boiler is not installed outdoors, air
intake in the installation area is compulsory.
- C12,C12x; C32,C32x; C42,C42x; C52,C52x; C82,C82x, C92,C92x boiler type: appliance
with airtight chamber, with fl ue gas discharge pipe and pick-up of combustion air from
outside. It does not require an air intake point in the installation area. This type MUST
be installed using concentric pipes, or other types of discharge designed for condensing
boilers with an airtight chamber.
The boiler can be installed indoor in multiple locations providing the combustion products
are discharged outside the room and the combustion air is drawn in from outside the room.
In this case, the room does not require any ventilation openings because the boiler has a
combustion circuit which is "sealed" with respect to the installation environment.
But if combustion air is taken from the installation room, the room must be fi tted with ventilation
openings complying with the technical standards and suitably dimensioned.
Consider the clearances necessary to access the safety and adjustment devices and to
perform maintenance operations.
Check that the electric protection level of the appliance is suitable for the installation room
characteristics.
If the boilers are supplied with fuel gas of a specifi c weight greater than that of the air, the
electric parts will have to be positioned more than 500mm above ground level.
The boiler is fi tted 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 down to an air temperature
in the installation area of >0°C.
To take advantage of this protection (based on burner operation), the boiler 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.
MINIMUM DISTANCES (Fig. 8)
For correct appliance positioning, bear in mind that:
- it must not be placed above a cooker or other cooking device
- it is forbidden to leave infl ammable products in the room where the boiler is installed
- heat-sensitive walls (e.g. wooden walls) must be protected with proper insulation.
3.6 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 modifi ed in any way.
The condensation exhaust system downstream of the appliance (1) 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 (2) between the
condensation exhaust pipe of the appliance and the condensation exhaust system.
The disconnection must be such as to ensure an atmospheric connection between the
inside of the condensation exhaust system pipe and the environment in order to avoid that
the downstream exhaust pipe of the product can take on positive or negative pressure with
respect to the environment itself. Fig. A: example of a connection between the condensation
exhaust pipe (3) and the exhaust system (4).

3.7 Fixing the condensate drain pipe
The boilers leave the factory with the condensate drain (A) and safety valve drain (B) pipes
already installed.
Connect the end of the condensate drain pipe supplied to another specifi cally inspected
connection device prepared (as indicated in UNI EN 677) avoiding creating creases where the
condensate can stagnate and possibly freeze.
The manufacturer is not responsible for any damage caused by the lack of conveying the
condensate or by freezing it.
The drain connection line must be leakproof and adequately protected from the risk of frost.
Before putting the appliance into service, make sure that the condensate can be properly
evacuated.
3.8 Positioning the wall-mounted boiler and hydraulic
connections (fi g. 9)
The boiler comes as standard with a boiler support plate. The position and dimension of
hydraulic fi ttings are shown in the detail drawing. For the assembly, proceed as follows:
- position the cardboard template on the wall. Using a spirit level, check the correct hori-
zontal plane and the fl atness of the boiler support surface; make it thicker if needed
- mark the fi xing points
- remove the cardboard template and drill the required holes
- fasten the upper boiler support crosspiece to the wall, using suitable anchor plugs
- verify correct horizontality with a spirit level
- carry out the hydraulic connections.
- hang the boiler.
