CONNECTING UP
SYSTEM
To protect the heat system from being
damaged by corrosion, incrustation or
deposits, after installation it is extremely
important to clean the system using suita-
ble products such as, for example, Sentinel
X300 or X400.
Complete instructions are provided with
the products but, for further information,
y o u m a y d i r e c t l y c o n t a c t S E N T I N E L
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 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.
WARNING: Failur e t o 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).
A sticker inside the module includes identifi-
cation and gas type data specific to the
module.
2.3.1
Condensation drain
installation.
A siphoned drain must be connected to the
civil drain by a pipe with minimum 5 mm
per meter gradient for condensation collec-
tion.
Only normal plastic civil drain pipes are
suitable to convey condensation to the
building's sewer drain.
2.3.2
Gas pipe filter
The gas valve is fitted with a standard filter.
This filter is not capable of filtering all impuri-
ties and to prevent poor gas valve operation
or failure of any gas valve safety feature, it is
advisable to fit a suitable filter on the gas
supply pipe.
2.5
FILLING THE SYSTEM
Cold system filling pressure must be 1 bar.
The system must be filled slowly so that air
bubbles are released through the specific
escapes.
2.6
EXHAUST
The boiler is supplied with a 80mm gasket,
which must be fitted over the exhaust ter-
minal prior to the flue being installed. (11
fig. 4-4/a-4/b).
2.6.1
Type B
(fig. 4)
If the inlet is not connected, the boiler
should be regarded a Class B device. 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 informa-
tion on how to configure the boiler in this
mode see figure 4.
The maximum overall length of ø 80
exhaust flues is determined by the load
losses of the single accessories installed
and should not exceed 16 mmH
2
O (“60
BFR”) and 28 mmH
2
O (“100 BFR”).
2.6.2
Type C
(figg. 4/a-4/b)
The boiler becomes a Class C device when
the intake terminal is removed from the
flange and the intake is connected to sepa-
rate exhaust ducts (fig. 4) or with coaxial
exhaust (fig. 4/b).

WARNING: Before installing accessories, lubricate
the internal part of gaskets with silicon-based pro-
ducts. Avoid using oils and greases.
