3.3 Handling
After unpacking, handling of the boiler is done manually using the
support frame (fig. 10).
3.4 Installation room
When the boiler is first started the siphon for collecting the
condensate is empty. It is therefore indispensable to create
a head of water filling the siphon before starting up, following
these instructions:
- remove the siphon by releasing it from the plastic pipe
connecting to the combustion chamber
- fill the siphon about 3/4” full with water, making sure it is
free of any impurities
- check the float of the plastic cylinder
- put back the siphon, being careful not to empty it, and
secure it with the clip
The plastic cylinder inside the siphon has the job of preventing
combustible gas coming out into the surroundings if the appliance is
started without first creating the head of water in the siphon.
Repeat this operation during routine and extraordinary maintenance
operations.
The FAMILY CONDENS IS E boiler can be installed in various types
of room, as long as the combustion product discharge and combus-
tion air suction are outside the room itself.
In this case, the room does not require any ventilation opening since
the FAMILY CONDENS IS E boiler has an "airtight" combustion cir-
cuit in relation to the installation environment
Consider the clearances necessary to access safety and ad-
justment devices and to perform maintenance operations.
Check that the electric protection level of the appliance is suit-
able for the installation room characteristics.
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 500mm above ground level.
3.5 Installation on appliances that are old or that need to
be updated
When the FAMILY CONDENS IS E boiler is installed in old systems
or systems being updated, verify that:
- The smoke pipe is suitable for the temperature of the combus-
tion 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 con-
densate 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 charac-
teristics of the system.
- The system has been washed and cleaned of mud and grime,
de-aerated and water tight.
- The boiler condensate drain system (siphon) is connected and
routed to the collection of "white" water.
- There is a treatment system for when the supply/make-up water is
particular (the values in the table can be used as reference values).
Supply water values
pH 6-8
Electric conductivity
less than 200 μS/cm (25 °C)
Chlorine ions less than 50 ppm
Sulphuric acid ions less than 50 ppm
Total iron less than 0.3 ppm
M alkalinity less than 50 ppm
Total hardness less than 35°F
Sulphur ions None
Ammonia ions None
Silicon ions less than 20 ppm
The manufacturer is not liable for any damage resulting from
the incorrect construction of the flue gas discharge system.
The flue gas discharge pipes for condensing boilers are made
of special materials that are different compared to those made
for standard boilers.
3.6 Boiler installation
For correct installation, keep in mind that (fig. 11):
- the boiler must not be placed above a stove or other cooking ap-
pliance
- 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
- the minimum clearances for technical and maintenance interven-
tions must be respected.
The boiler is supplied with a pre-assembly template which allows
for realising the connections to the heating and domestic hot water
system without the boiler, which may be subsequently assembled,
standing in the way.
Connect the discharge manifold to a suitable discharge system (for
details, see chapter "Discharge manifold").
FIXING OF THE PRE-ASSEMBLY TEMPLATE (fig. 12)
The FAMILY CONDENS IS E boiler is designed and built to be in-
stalled in heating and domestic hot water systems.
The position and dimension of hydraulic fittings are shown in the
drawings.
- Position the plate with the aid of a spirit level: check the correct
horizontal plane and the planarity of the boiler rest surface; make
it thicker if needed
- Trace the fixing points
- Remove the template and carry out the drilling
- Fix the plate to the wall using appropriate plugs.
- Check the correct horizontality with a spirit level.
FIXING THE BOILER (fig. 12)
- Hook the boiler to the brackets on the plate.
FIXING OF THE CONNECTION COVER (fig. 13)
On completing boiler installation operations and relative connections
to the water and gas mains, fit the connection cover (A - B) so that its
hooks fit into the specific slots in the lower part of the boiler. Secure
the connection cover with screw C contained in the documentation
envelope supplied with the boiler.
3.7 Hydraulic connections (fig. 16-17-18)
Connect the fittings and gaskets supplied with the system.
We recommend connecting the boiler to the system adding shut-
off valves for the heating system; for this purpose a heating system
valves kit and heating valves kit with filter is available.
Connect brass taps supplied to the fittings and the boiler.
For connection to the remote storage tank use ¾” fittings.
The selection and the installation of the system components
are the responsibility of the installer, who must operate accord-
ing to the rules of good technique and current Legislation.
A carrying case kit is available that allows to make connections
quickly and without unnecessary waste on each system.

DISCHARGE MANIFOLD
The discharge manifold collects: condensate water, any evacuation
water from the safety valve and the system discharge water (fig.19).
The manifold must be connected via a pipe not provided with
the boiler to an appropriate collection and evacuation system
in the white water discharge drain in compliance with current
regulations.
