3 - VARIABLE SPEED CIRCULATOR WITH MAXIMUM FIXED
SPEED MODE (P90 = 1)
In this mode the modulating circulator runs continuously at full speed.
Used on systems with high pressure drops in which it is necessary
to make the most of the boiler discharge head in order to ensure a
sufficient circulation (system output at maximum speed less than 600
litres per hour).
Used in the presence of hydraulic separators with high output in the
downstream circuit.
In operational terms:
- Enter parameter 90
- Set the parameter = 1
4 - EXCEPTIONAL USE
WITHOUT REGULATED SPEED (P90 = 0)
This mode should be used in exceptional cases in which a traditional
circulator without speed adjustment is used in the boiler. It assumes
that the adjustable speed circulator has been removed and replaced
with a non-adjustable speed circulator.
The BE06 card connected to the CN9 connector must be
removed and replaced with a connector with jumper to be
inserted again in the CN9 connector. The latter connection
is mandatory and if not performed can cause system
malfunctions.
In operational terms:
- Enter parameter 90
- Set the parameter = 0

3 - INSTALLATION
3.1 Receiving the product
The Family Aqua Condens 3.5 BIS boiler is supplied in a single
pack protected by cardboard packaging.
The boiler is supplied as standard with the following material:
- Instruction booklet for the installer and user
- Bar code labels
- Pre-assembly template
- Package with hydraulic fittings
- External probe
- Plastic pipe
- LPG conversion kit.
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.

3.3 Handling
After unpacking, handling of the boiler is done manually using the
support frame (fig. 3).
3.4 Boiler installation room
The Family Aqua Condens 3.5 BIS boiler can be installed in various
types of room, as long as the combustion product discharge and
combustion air suction are outside the room itself.
In this case, the room does not require any ventilation opening
since the Family Aqua Condens 3.5 BIS boiler has an "airtight"
combustion circuit in relation to the installation environment
Consider the clearances necessary to access 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 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 Aqua Condens 3.5 BIS boiler is installed in old
systems or systems being updated, verify that:
- The smoke pipe 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 has been washed and cleaned of mud and grime, de-
aerated and water tight. It is recommended to install a magnetic
filter on the return of the system.
- The boiler condensate drain system (siphon) is connected and
routed to the collection of "white" water.
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. 4):
- the boiler must not be placed above a stove or other cooking
appliance
- 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
interventions 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").
