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. 5):
- 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. 6)
The Family Aqua Condens 3.5 BIS boiler is designed and built to be
installed 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
- Hook the boiler to the brackets on the plate.
FIXING OF THE CONNECTIONS COVER - accessory available
by reques (fig. 7)
On completing boiler installation operations and relative connections
to the water and gas mains, fit the connections cover (A - B) so that
its hooks fit into the specific slots in the lower part of the boiler. Fix
the connections cover with screw C.
3.7
Hydraulic connections (fig. 11-12-13)
Connect the fittings and gaskets supplied with the system.
We recommend connecting the boiler to the systems introducing
both the DHW shut-off valve as well as the 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.
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.
If consumption water has a total hardness between 25° F and
50° F, install a DHW treatment kit; with a total hardness great-
er than 50° F, the kit's effectiveness progressively reduces and
therefore the use of an appliance of higher performance or total
softening is recommended; even with a total hardness of less
than 25° F, a filter of appropriate size must be installed if the wa-
ter comes from the mains that is not perfectly clean/cleanable.
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.14).
The manifold must be connected via a rubber pipe (not provid-
ed) to an appropriate collection and evacuation system in the
white water discharge drain in compliance with current regula-
tions. The outer diameter of the manifold is 20 mm: it is there-
fore advisable to use a rubber pipe ø18-19 mm closed with a
suitable clamp (not provided).
Regularly check that the discharge manifold is not blocked by
solid residues that might prevent the outflow of condensate wa-
ter.
The manufacturer is not liable for any damage resulting from
the failure to channel the condensate.
Sealing of the condensate drainage connection line must be
guaranteed.
The boiler manufacturer is not responsible for any floods
caused by the intervention of the safety valves.
3.8
Installing the external probe
The correct operation of the external probe is fundamental for the
good operation of the climatic control.
INSTALLING AND CONNECTING THE EXTERNAL PROBE
The probe must be installed on an external wall of the building to be
heated, observing the following indications:
- it must be mounted on the side of the building most often exposed
to winds (the NORTH or NORTHWEST facing wall), avoiding direct
solar irradiation;
- it must be mounted about 2/3 of the way up the wall;
- it must not be mounted near doors, windows, air outlet points, or
near smoke pipes or other heat sources.
The electrical wiring to the external probe is made with a bipolar ca-
ble with a section from 0.5 to 1 mm
2
(not supplied), with a maximum
length of 30 metres. It is not necessary to respect the polarity of the
cable when connecting it to the external probe. Avoid making any
joints on this cable however; if joints are absolutely necessary, they
must be watertight and well protected.
Any ducting of the connection cable must be separated from live ca-
bles (230V AC).
FIXING THE EXTERNAL PROBE TO THE WALL
The probe must be fixed on a smooth part of the wall; in the case of
exposed brickwork or an uneven wall, look for the smoothest possi-
ble area (fig.15).
Loosen the plastic upper protective cover by turning it anticlockwise.
After deciding on the best fixing area of the wall, drill the holes for the
5x25 wall plug.
Insert the plug in the hole.
Remove the card from its seat.
Fix the box to the wall, using the screw supplied.
Attach the bracket, then tighten the screw.
Loosen the nut of the cable grommet, then insert the probe connec-
tion cable and connect it to the electric clamp.
To make the electrical connection between the external probe and
the boiler, refer to the “Electrical wiring” chapter.
Remember to close the cable grommet well, to prevent any air
humidity getting in through the opening.
Put the board back in its seat.
Close the plastic upper protective cover by turning it clockwise. Tight-
en the cable grommet very well.
3.9
Electrical wiring
The Family Aqua Condens 3.5 BIS boiler leaves the factory com-
pletely wired and only need to be connected to the mains power sup-
ply (using the supplied power cable) and the ambient thermostat (TA)
and/or timer, via relevant terminals (fig. 16).
- Set the system's main switch to "off"
- Loosen the fixing screws (A) of the connections cover
