contained inside the appliance drops to
below 6°C. The anti-freeze function is ensu-
red, 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
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

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
system), X400 and X800 (old system) or
Fernox Cleaner F3. Complete instructions
are provided with the products but, for
further information, you may directly con-
tact 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 /h and gas
3
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.
2.2. 1 Connection of condensation
water trap
The drip board and its water trap must be
connected to a civil drain through a pipe
with a slope of at least 5 mm per metre to
ensure drainage of condensation water.
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building's sewer pipes.
2.2.2 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.
2.3 INITIAL PHASE SYSTEM FILLING
(fig. 5)
The charge pressure, with the system cold,
must be between 1 and 1.5 bar.
The filling is to be done slowly to allow air
bubbles to escape through the air vents.
2.3. 1 System draining (fig. 5)
To drain the system, turn off the boiler and
use the discharge valve (5 fig. 5).
2.4 FORCED EXHAUST
TYPE B23P-B53P (fig. 6)
To set this exhaust configuration, refer to
fig. 6. The boiler is provided also of a rubber
gasket Ø 80 to be used as shown in the figu-
re.
The maximum total length of the exhaust
pipe ø 80 is determined by the load los-
ses of the individual accessories inserted
and must not be more than 15 mm H
