The boiler must be installed in a fixed loca-
tion and only by specialized and qualified
firms in compliance with all instructions
contained in this manual. Furthermore, the
installation must be in accordance with cur-
rent standards and regulations.
2.1 INSTALLATION
- In the rooms where “type B” boilers are
installed, the air required for correct
combustion of the gas consumed by the
appliance must be able to flow in. It is the-
refore necessary to make openings that
cannot be blocked in the outer walls,
which must be at least 6 cm
2
for every
kW of thermal capacity installed and with,
in any case, a minimum of 100 cm
2
.
- “Type C” appliances, with combustion
chamber and air supply sealed off from
the environment, can be installed in any
room in the house.
- “Type B and C” boilers are suitable for
functioning in a partially protected place,
as according to EN 297, with maximum
environmental temperature of 60°C and
minimum of -5°C. We recommend instal-
lation of these boilers under the protru-
ding slope of a roof, on a balcony, or in a
protected niche, always providing they
are not directly exposed to adverse
weather (rain, hail, snow). The boilers are
provided already equipped with anti-free-
ze functions.
2.1.1 Anti-freeze function
The boilers are equipped with anti-freeze
function which activates the pumps and the
burner when the temperature of the water
contained inside the appliance drops to
below 6°C.
The anti-freeze function is ensured, howe-
ver, only if:
- the boiler is correctly connected to the
gas and electricity supply circuits;
- the boiler is constantly fed;
- the boiler ignition is not blocked;
- the essential components of the
boiler are all in working order
In these conditions the boiler is protected
against frost down to an environmental
temperature of -5°C.
ATTENTION: In the case of installation in a
place where the temperature drops below
0°C, the connection pipes must be pro-
tected.
2.2 BOILER SUPPORT BRACKET (fig. 4)
For the mounting of the support bracket of
the boiler, which is supplied, observe the fol-
lowing instructions (fig. 4):
– Fix the bracket to the wall with appro-
priate dowels.
– Check with a spirit level that it is perfec-
tly in horizontal plane.
– To fix the boiler with the lives put in evi-
dence in figure.
2.2.1 Complementary accessories
To facilitate connecting the boiler to the
system, the following accessories can be
supplied on request:
– Installation plate code 8081217
– Curvette kit code 8075423
– Taps kit code 8091809
– Antifr eeze heat er s kit -15° C code
8089806 (BF models)
– Mixed ar ea kit ZONA MIX code
8092234.
For detailed information on the assembly of
fittings, see the instructions contained in
the box.
2.2.2 Flow regulator (fig. 5)
In entrance of the D.H.W. a regolator of
color capacity is installed brown for the
ver s.
"25/55" and blue for the ver s.
"30/55" ; the regolator is inserted in a bag
to equipment of the boiler.
2.3 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, before
installation it is extremely important to
clean the system using suitable products
such as, for example,
Sentinel X300 (new
systems), X400 and X800 (old systems)
or Fernox Cleaner F3
. Complete instruc-
tions are provided with the products but,
for further information, you may directly
contact SENTINEL PERFORMANCE SOLU-
TIONS LTD or FERNOX COOKSON ELECTRO-
NICS.
For long-term protection agains corrosion
and deposits, the use of inhibitors such as
Sentinel X100 or Fernox Protector F1 is
recommended after cleaning the system. It
is important to check the concentration of
the inhibitor after each system modifica-
tion and during maintenance following the
manufacturer’s instructions (specific tests
are available at your dealer). The safety
valve drain must be connected to a collec-
tion funnel to collect any discharge during
interventions. If the heating system is on a
higher floor than the boiler, install the
on/off taps supplied in kit optional on the
heating system delivery/return pipes.
WARNING: Failure to clean the heat
system or add an adequate inhibitor inva-
lidates the device’s warranty.
Gas connections must be made in accor-
dance with current standards and regula-
tions. When dimensioning gas pipes from
the meter to the module, both capacity
volume (consumption) in m
3 /h and gas
density must be taken into account.
The sections of the piping making up the
system must be such as to guarantee a
supply of gas sufficient to cover the maxi-
mum demand, limiting pressure loss
between the gas meter and any apparatus
being used to not greater than:
– 1.0 mbar for family II gases (natural gas);
– 2.0 mbar for family III gases (butane or
propane).
An adhesive data plate is sticked inside the
front panel; it contains all the technical data
identifying the boiler and the type of gas for
which the boiler is arranged.
2.3.1 Filter on the gas pipe
The gas valve is supplied ex factory with an
inlet filter, which, however, is not adequate
to entrap all the impurities in the gas or in
gas main pipes.
