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 INSTALLATION
– Boilers can be installed in all domestic
environments without any whatsoever
limit in terms of location and comburent
air supply.
– These boilers can also be installed in
partially covered areas, as per EN 15502,
with a maximum ambient temperature
of 60°C and a minimum ambient tempe-
rature of -5°C. It is generally advisable
to install the boilers below weathered
roofs, on the balcony or in a protected
niche, to protect them from exposure to
weathering agents (rain, hail and snow).
All boilers provide a standard antifreeze
function.
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 6°C. 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
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
protected.
2.2 BOILER SUPPORT BRACKET
For the mounting of the support bracket of
the boiler, which is supplied, observe the
following instructions (fig. 4):
– Fix the bracket to the wall with appro-
priate dowels.
– Check with a spirit level that it is per-
fectly in horizontal plane.
– To fix the boiler with the lives put in evi-
dence in figure.
2.2.1 Complementary accessories
To simplify connections to the hydraulic and
gas supplies, it is also possible to use the
following accessories:
– Mounting plate, code 8081217
– Kit with bends, code 8075423
– Kit with faucets, code 8091833
– Antifreeze heaters kit -15°C, code
8089805
– Mixed area kit ZONA MIX, code 8092234.
For detailed information on the assembly
of fittings, see the instructions contained
in the box.
2.2.2 Flow regulator (fig. 5)
In entrance of the D.H.W. a regolator of
color capacity is installed brown for the
vers. “25/55 ErP” and blue for the vers.
“30/55 ErP”; the regolator is inserted in a
bag to equipment of the boiler.
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 provided with the products but, for fur-
ther information, you may directly contact
SENTINEL PERFORMANCE SOLUTIONS
LTD or FERNOX COOKSON ELECTRONICS.
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 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
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
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 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
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 SYSTEM FILLING
Filling of the boiler and the system is done
by the charge load faucet (fig. 23/a).
The charge pressure, with the system cold,
must be between 1 and 1.5 bar. During
system filling you are recommended to
keep the main switch turned OFF. Filling
must be done slowly so as to allow any
air bubbles to be bled off through the air
valves.
2.4.1 System draining (fig. 5/a)
To drain the system, turn off the boiler and
to loosen with one key from 13 the appro-
priate download of some turns (fig. 5/a).
2.5 INSTALLATION OF
COAXIAL DUCT
(ø 60/100 - ø 80/125)
The axial suction and discharge pipes are
supplied in a special kit (that can be pur-
chased separately) along with assembly
instructions.
The diagrams of fig. 6 illustrate some
examples of different types of dischar-
ge modalities allowed and the maximum
lengths that can be reached.
2.6 INSTALLATION OF SEPARATE
DUCTS (ø 80 - ø 60)
The separate ducts kit code 8089911/14

IMPORTANT:
- The insertion of each additional 90°
bend with a diameter of 60/100
reduces the available section by 1.5
meters.
- The insertion of each additional
90° bend with a diameter of 80/125
reduces the available section by 2
meters.
- Each additional 45° curve installed
reduces the available length by 1.0
metres.
- During assembly it is important to
make sure that the kit with axial
pipes. (1) is positioned horizontally.
NOTE: Before connecting accessori-
es, it is always advisable to lubricate
the internal part of the gaskets with

must be siphoned off at the foot of the
pipe. The usable height of the water trap
must be at least 150 mm.
2.7 FORCED EXHAUST
TYPE B23P-B53P (fig. 9/a)
This type of exhaust pipe is installed using
the special kit, code 8089911. For kit
assembly instructions, refer to point 2.6.
Protect the intake with the optional acces-
sory, code 8089501.
The accessory is assembled by cutting a
50 mm long segment from an ordinary
ø 80 extension and inserting it on the air
intake, on which the accessory is then fit-
ted, anchored to the pipe segment with the
screws provided (fig. 9/a).
Maximum flow resistance must be no
more than 15 mm H2O (ATTENTION: the
total length of each pipe should not exceed
25 m, even if the total loss is below the
maximum applicable loss.)
As the maximum pipe length is determi-
ned by adding up the flow resistance of
the various individual accessories installed,
refer to Table 1-1/a for calculation.

2) When siting terminals, where materials that may be subject to the action of the combu-
stion products are present in the vicinity, e.g., eaves, gutters and downspouts painted or
made of plastic material, projecting timberwork, etc., distances of not less than 1500 mm
must be adopted, unless adequate shielding is provided to guard these materials.

2.9.4 Use with different
electronic systems
Some examples are given below of boiler
systems combined with different electro-
nic systems. Where necessary, the para-
meters to be set in the boiler are given.
The electrical connections to the boiler
refer to the wording on the diagram (fig.
11). The zone valve control starts at every
demand for heating of the zone 1 (it is
from part of the TA1 or the CR).

2.8 POSITIONING THE
OUTLET TERMINALS (fig. 10)
The outlet terminals for forced-draught
appliances may be located in the external
perimeter walls of the building.
To provide some indications of possible
solutions, Table 3 gives the minimum
distances to be observed, with reference to
the type of building shown in fig. 10.
2.9 ELECTRICAL CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME.
The electric power supply to the boiler
must be 230V - 50Hz single-phase through
a fused main switch, with at least 3 mm
spacing between contacts. Respect the L
and N polarities and the earth connection.
NOTE: SIME declines all responsibility for
injury or damage to persons, animals or
things, resulting from the failure to pro-
vide for proper earthing of the appliance.
2.9.1 Chronothermostat connection
Connect the chronothermostat as indicated
in the boiler electrical diagram (see fig. 11)
after having removed the existing bridge.
The chronothermostat to be used must be
of a class conforming to the standard EN
607301 (clean electrical contact).
2.9.2 Remote control
SIME HOME
connection (optional)
The boiler is designed for connection to a
remote control unit, supplied on request
(SIME HOME code 8092280/81).
The remote control unit allows for comple-
te remote control of the boiler.
The boiler display will show the following
message:
For installation and use of the remote con-
trol, follow the instructions in the package.
NOTE: Ensure PAR 10 set to 1 (PAR 10 = 1).
2.9.3 External sensor connection
The boiler is designed for connection to an
external temperature sensor, supplied on
request (code 8094101), which can auto-
matically regulate the temperature value of
the boiler output according to the external
temperature. For installation, follow the
instruction in the package.
It is possible to make corrections to the
values read by the drill acting on the PAR
11.
