INSTALLATION
The boiler must be installed in a fixed loca-
tion and only by specialized and qualified
firms in compliance with all instructions con-
tained 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
therefore necessary to make openings
that cannot be blocked in the outer walls,
which must be at least 6 cm
kW of thermal capacity installed and
with, in any case, a minimum of 100
2
cm
.
- "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 value PAR 10.
The anti-freeze function is ensured, however,
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 tem-
perature of -5°C.
ATTENTION: In the case of installation in a
place where the temperature drops below
0°C, the connection pipes must be protec-
ted.

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-
64

for every
priate dowels.
– Check with a spirit level that it is perfec-
tly in horizontal plane.
2.2. 1
Complementary accessories
To facilitate connecting the boiler to the
system, the following accessories can be
supplied on request, complete with instruc-
tions for assembly:
- Installation plate code 80781209
- Elbows kit code 8075434
- Taps kit code 8091826.
2.2.2
Flow regulator (fig. 4/a)
At the inlet of the hot water a flow regulator
can be installed, (yellow) for the "25/55"
version and (brown) for the "30/55" ver-
sion. The regulator is supplied in the kit of
the connecting taps code 8091826.
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 instructions are pro-
vided with the products but, for further infor-
mation, you may directly contact SENTINEL
PERFORMANCE SOLUTIONS LTD or FER-
NOX COOKSON ELECTRONICS. For long-
term protection agains corrosion and depo-
sits, the use of inhibitors such as Sentinel
X100 or Fernox Protector F1 is recom-
mended after cleaning the system. It is
important to check the concentration of the
inhibitor after each system modification and
during maintenance following the manufac-
turer's instructions (specific tests are availa-
ble at your dealer). The safety valve drain
must be connected to a collection 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 op tional on t he heating sy s t em
delivery/return pipes.
WARNING: Failure to clean the heat
system or add an adequate inhibitor invali-
dates 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 volu-
me (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 sup-
ply of gas sufficient to cover the maximum
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. To prevent malfunctioning of the
valve, or in certain cases even to cut out the
safety device with which the valve is equip-
