DESCRIPTION
The
Family
boilers have a new ACC combustion control system (active
combustion control).
This new control system, developed by
Riello
, in all circumstances provides
functionality, effi ciency and low emissions.
The ACC system uses an ionisation sensor immersed in the burner fl ame,
whose information allows the control board to operate the gas valve that
regulates the fuel.
This sophisticated control system provides for the auto adjustment of the
combustion, thereby eliminating the need for an initial calibration
The ACC system can adapt the boiler to operate with diff erent gas
compositions, diff erent pipe lengths and various altitudes (within the design
limits).
The ACC system can also perform an auto-diagnostic operation that locks
out the burner before the permitted upper emission limit is exceeded.
Family
is a type C condensing wall-hung boiler to be used for heating and
the production of domestic hot water: Depending on the fume discharge
accessory used, it is classifi ed in categories B23P; B53P; C13,C13x;
C33,C33x; C43,C43x; C53,C53x; C83, C83x; C93, C93x.
In confi guration B23P (when installed indoors), the appliance cannot
be installed in bedrooms, bathrooms, showers or where there are open
fi replaces without a proper air fl ow. The room where the boiler is installed
must have proper ventilation. Detailed requirements for the installation of
the fl ue, the gas piping and for ventilating the room, can be found in UNI
7129-7131.
In confi guration 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
Cleaning the system and characteristics of the 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, fi lming agents, etc.) and check the
parameters in the table are within the values indicated.

Receiving the product
The
Family
boiler is shipped in a single pack, protected by cardboard
packaging.
The boiler is supplied as standard with the following material:
- Instruction booklet for the user
- Instructions booklet for the installer and for the technical assistance
service
- Bar code labels
- Pre-assembly template
- Package with plumbing fi ttings
- Bypass valve
- Flat gasket
- SRD device
- Condensate drain pipe
- Flexible hose safety valve
- Electric connections box
b
The instruction booklets are an integral part of the boiler and there
it is recommended to read them carefully and keep them in a safe
place.

Handling (Fig. 6)
After unpacking, handling of the boiler is done manually using the support
frame.
3.5
Installation room
The
Family
boiler can be installed in various types of room, as long as the
discharge of the combustion product and the combustion air suction are
outside the room itself.
In this case the room does not need any ventilation opening since the
Family
boilers have a combustion circuit that is "airtight" with respect to the
installation environment.
b
Consider the clearances necessary to access safety and adjustment
devices and to perform maintenance operations.
b
Check that the electric protection level of the appliance is adapted to
the installation room characteristics.
b
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.
3.6
Installation on appliances that are old or that
need to be updated
When the
Family
boiler is installed in old systems or systems being
updated, check that:
- The fl ue is suitable for the temperature of the combustion products with
condensation, calculated and built according to Standard, is as straight
as possible, airtight, insulated and has no blockages or narrow sections.
It is equipped with appropriate condensate collection and discharge
systems
- The electrical system is installed in compliance with the specifi c standards
and by qualifi ed personnel
- The fuel supply line and eventual tank (LPG) are made according to
specifi c Standards
- The expansion tank ensures the total absorption of the dilatation of the
fl uid contained in the system
- The fl ow rate and head of the circulator are suitable to the characteristics
of the system
- The system is washed, cleansed of any mud, build-up, vented and
sealed. It is recommended that a magnetic fi lter be installed on the
system's return line
- The boiler condensate drain system (siphon) is connected and routed to
the collection of "white" water
3.7
Installation regulations
The installation must be carried out by qualifi ed personnel, in compliance
with the following reference standards:
- UNI 7129-7131
- CEI 64-8.
Always comply with local standards of the Fire Department, the Gas
Company and with possible municipal dispositions.
POSITION
Family
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:
- B23P-B53P type boiler - 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.
- C13, C13x type boiler; C33, C33x; C43, C43x; C53,C53x; C83, C83x,
C93, C93x: 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.
Family
can be installed outdoors, in a partially protected place (i.e. a place
where the boiler is not exposed to direct contact or infi ltration of rain, snow
or hail. The boiler can operate in a temperature range from -5°C to +60°C.
