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
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 collection funnel to collect any dischar-
ge during interventions. If the heating
system is on a higher floor than the boiler,
install the on/off taps supplied in kit optio-
nal 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
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
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.
2.3.2
Filter on the gas pipe
The gas valve is supplied ex factory with an
76
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.
2.4
INITIAL PHASE
SYSTEM FILLING
The charge pressure, at cold start, must
be 1 bar.
The filling is to be done slowly to allow air
bubbles to escape through the air vents.
2.4. 1
System draining
(fig. 5)
To drain the system, turn off the boiler and
use the discharge valve (2 fig. 5).
2.5
EXHAUST
The boiler is supplied with a 80 mm gasket,
which must be fitted over the exhaust ter-
minal prior to the flue being installed (11
fig. 4/b - 4/c - 4/d).
2.5. 1
Type B (fig. 6)
If the inlet is not connected, the boiler
should be regarded a Type B device.

/h and gas
When installing the boiler in locations
where it needs to be protected from water,
replace the intake terminal inserted in the

flange with terminal code 8089510.
For information on how to configure the
boiler in this mode see figure 6.
WARNING:
The maximum overall length of ø 80
exhaust flues is determined by the load
losses of the single accessories installed
and should not exceed 42 mm H
When load loss exceeds 4 mm H
order to assure the correct operation of
the appliance, set the installer parameter
PAR 9 as indicated in TABLE 1 (see point
3.3 to access installer parameters).
The exhaust pipe can be connected to exi-
sting chimneys.
When the boiler works at low temperature
is possible to use normal chimneys at the
following conditions:
– The chimney must not be used by other
boilers.
– The inside of the chimney must be pro-
tected from direct contact with the boi-
ler condensation. Combustion products
must be conveyed with a flexible piping
or rigid plastic pipes with a diameter of
about 100-150 mm providing so to the
condensation siphoned drainage at the
end of the pipe. The useful height of the
siphon must be at least 150 mm.
2.5.2
Type C (fig. 7 - fig. 8)
The boiler becomes a Type C device when
the intake terminal is removed from the
flange and the intake is connected to sepa-
rate exhaust ducts (fig. 7) or with coaxial
exhaust (fig. 8).
