3.3 Handling (Fig. 6)
After unpacking, handling of the boiler is done manually using the support frame.
3.4 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 specific weight greater than that of the air,
the electric parts will have to be positioned more than 500 mm above ground level.
3.5 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 flue 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 specific standards and by
qualified personnel.
- The fuel supply line and eventual tank (LPG) are made according to specific standards.
- The expansion tank ensures the total absorption of the dilatation of the fluid contained
in the system.
- The flow 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 filter be installed on the system's return line.
- The boiler condensate drain system (siphon) is connected and routed to the collection
of "white" water.
3.6 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
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 flue 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.
- C(10); C13,C13x; C33,C33x; C43,C43x; C53,C53x; C83,C83x, C93,C93x type boiler:
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. 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 infiltration of rain, snow or hail. The boiler can operate in
a temperature range from >0°C to +60°C.
Family 25 IS can also be installed outdoor in the built-in unit.
ANTI-FREEZE SYSTEM (Fig. 7)
The boiler comes as standard with an automatic anti-freeze system, which activates when
the temperature of the primary circuit water drops below 5°C. This system is always active
and provides protection for the boiler up to an air temperature in the installation area of 0°C.
b
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.
b
When the boiler is installed in a place where there is a risk of freezing, with
outside air temperatures below 0 °C, an antifreeze heater kit must be used to
protect the DHW circuit and condensation drain (available on request - see
catalog) that protects the boiler up to -15 °C.
b
The installation of the antifreeze heater kit must be carried out only by
authorized personnel, following the instructions contained in the kit.
In normal operating conditions, the boiler can protect itself against frost.
If the machine is left without power for long periods in areas where temperatures may fall
below 0°C, and you do not want to drain the heating system, you are advised to add a specific,
good quality anti-freeze liquid to the primary circuit. Carefully follow the manufacturer'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.
MINIMUM DISTANCES (Fig. 8a-8b)
To ensure access to the boiler for normal maintenance operations, respect the minimum
installation clearances envisaged. 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 inflammable products in the room where the boiler is installed
- heat-sensitive walls (e.g. wooden walls) must be protected with proper insulation.
b
When installing it is ABSOLUTELY NECESSARY to provide the spaces necessary
for the introduction of the instrument for analysing the combustion. We have
provided a sample diagram where the distances between the boiler and wall unit /
recess have been obtained using an instrument with a length of 300 mm. Longer
instruments require more space.
3.7 Installation of condensate drain pipe (Fig. 9)
b
Before starting the boiler, even just temporarily, the SRD device supplied as
standard must be installed. The manufacturer is NOT responsible for any damage
caused to persons or objects by the installation of the boiler without the SRD device
being correctly installed.
For the installation proceed as follows:
- remove the plug (T) from the siphon
- fix the SRD device to the siphon (Fig. 9a), placing the gasket in-between, screwing it on
all the way and checking its seal
- connect the condensate discharge pipe (Fig. 9b) supplied as standard with the product,
then drain the condensate into a suitable drainage system in compliance with current
norms.
b
If it is not possible to fit the SRD device due to the interference with other objects
under the boiler, it is possible to fit it in a different position by inserting a connecting
pipe between the SRD device and the siphon in order to provide a perfect airtight
seal. The SRD device should always be positioned VERTICALLY in order to ensure
it functions correctly.
3.8 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 (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. 1: example of a connection between the condensation
exhaust pipe (3) and the exhaust system (4).
