INSTALLATION
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 current standards and
regulations.
2. 1
VENTILATION OF BOILER ROOM
The "25 OF" version boilers must be instal-
led in adequately ventilated domestic
rooms. It is essential that in rooms where
the boiler are installed at least as much air
can arrive as required by normal combu-
stion of the gas consumed by the various
appliances.
Consequently, it is necessary to make ope-
nings in the walls for the air inlet into the
rooms.
These openings must meet the following
requirements:
– have a total free section of at least 6
cm
for every kW of heat input, with a
2
minimum of 100 cm
2
;
– They must be located as close as possi-
ble to floor level, not prone to obstruc-
tion and protected by a grid which does
not reduce the effective section required
for the passage of air.
Models "25 BF TS", with a hermetically sea-
led combustion chamber and air supply cir-
cuit,may be installed in any room in the
home.

INSTALLATION PLATE
The op tional ins t allation plat e code
8075416 is supplied with an instruction
sheet for the fixing.
2.2. 1
Elbow kit
Follow the instructions shown in fig. 4 to
assemble the components supplied in optio-
nal kit code 8075418.
2.2.2
Isolating valves kit
To fit the isolating valves, supplied in kit code
8091806, follow the instructions mentio-
ned in fig. 4/a.
2.2.3
Replacement wall kit
for other makes
For assembly of the optional kit code
8093900 refer to the instruction sheet
provided with the kit.
2.3
CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, before
78
installation it is extremely important to
clean the system using suitable products
such as, for example, Sentinel X300 or
X400. Complete instructions are provided
with the products but, for further informa-
tion, you may directly contact SENTINEL
PERFORMANCE SOLUTIONS LTD.
For long-term protection agains corrosion
and deposits, the use of inhibitors such as
Sentinel X100 is recommended after clea-
ning the system. It is important to check
the concentration of the inhibitor after
each system modification and during main-
tenance following the manufacturer's
instructions (specific tests are available at
your dealer). The safety valve drain must
be connected to a collection funnel to col-
lect any discharge during interventions. If
the heating system is on a higher floor than
the boiler, install the on/off taps supplied in
kit code 8091806 on the heating system
delivery/return pipes.
WARNING: Failure to clean the
heat system or add an adequate
inhibitor invalidates 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.

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. To prevent malfunctioning
of the valve, or in certain cases even to cut
out the safety device with which the valve is
equipped, install an adequate filter on the
gas pipe.
2.5
SYSTEM FILLING (fig. 5)
Filling of the boiler and the system is done
by the charge cock (2).
The charge pressure, with the system cold,
must be between 1 and 1.2 bar.
