IMPORTANT
When carrying out commissioning of the boiler, you are highly recommended to perform the following
checks:
–
Make sure that there are no liquids or inflammable materials in the immediate vicinity of the boiler.
– Make sure that the electrical connections have been made correctly and that the earth wire is con-
nected to a good earthing system.
– Open the gas tap and check the soundness of the connections, including that of the burner.
– Make sure that the boiler is set for operation for the type of gas supplied.
– Check that the flue pipe for the outlet of the products of the combustion is unobstructed and has
been properly installed.
– Make sure that any shutoff valves are open.
– Make sure that the system is charged with water and is thoroughly vented.
– Check that the circulating pump is not locked.
– Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve
on the gas valve inlet.
–
The installer must provide the user with instruction in operation of the boiler and safety devices and
hand over the instruction booklet to the user.

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 cur-
rent 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 par-
tially covered areas, as per EN 15502, with
a maximum ambient temperature of 60°C
and a minimum ambient temperature 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 tem-
perature 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 COMPLEMENTARY ACCESSORIES
To simplify connections to the hydraulic and
gas supplies, it is also possible to use the
following accessories:
– Mounting plate, code 8081220
– Kit with bends, code 8075423
– Kit with faucets, code 8091806
– Kit with faucets boiler T, code 8091820
– Kit for the replacement of wall-mounting
assemblies of other manufacturers, code
8093900
– Solar kit for the instantaneous, code
8105101, in coupling to kit INSOL
– Mixed area kit ZONA MIX, code 8092234
– Solar kit INSOL only for heating boilers,
code 8092235
– Antifreeze heaters kit -15°C, code
8089806.
For detailed information on the assembly
of fittings, see the instructions contained
in the box.
2.3 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, befo-
re 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 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 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 invalidates the
device’s warranty.
Gas connections must be made in accordan-
ce with current standards and regulations.
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 sup-
ply 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 devi-
ce with which the valve is equipped, install
an adequate filter on the gas pipe.
2.4 SYSTEM FILLING (fig. 4)
Filling of the boiler and the system is done by
the system filling (11). The charge pressure,

NB: The “T” versions the loading is done
by loading tap externally mounted by the
installer.
2.4.1 System draining (fig. 4)
To drain the system, turn off the boiler and
use the discharge valve (7).
2.5 INSTALLATION OF
COAXIAL DUCT
ø 60/100 - ø 80/125 (fig. 6)
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 exam-
ples of different types of discharge modali-
ties allowed and the maximum lengths that
can be reached.
2.6 INSTALLATION OF SEPARATE
DUCTS ø 80 - ø 60 (figg. 7-8)
The kit with dedicated pipes enables to
separate the exhaust fumes pipes from the
air suction pipes (Fig. 7):
- The kit with dedicated ø 80 pipes, code.
8089912, includes a SUCTION DIAPHRAGM
THAT IS NOT used for these models. To be
able to use the air tap, cut its base with a
tool (A) and assemble it (B).
- The kits with dedicated ø 60 pipes, code
8089913, include a suction collar that
replaces the boiler collar (C).
It is now possible to insert an expansion or
bend in polypropylene without gaskets or
sealant.
The maximum overall length, resulting
from the sum of all the suction and dischar-
ge pipes, is determined by the load losses
of the single connected accessories and
should not exceed 10 mm H2O (version 12) -
15 mm H2O (version 25-30-35) (ATTENTION:
the total length of each pipe should not
exceed 25 m, even if the total loss is below
the maximum applicable loss.)
See Table 1-1/a for information on the load
losses of single accessories and the exam-
ple of Fig. 8 for information on how to calcu-
late load losses.

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 accessories, it is
always advisable to lubricate the internal
part of the gaskets with silicon products.
Avoid using oils and greases.

2.6.2 Connection to existing flues
The ø 80 or ø 60 exhaust pipe can also be
connected to existing flues. When the boiler
runs at low temperature, it is possible to use
standard flues provided that:
- The flue is not be used by other boilers.
- The interior of the flue is protected to pre-
vent a direct contact with condensation
from the boiler. The products of combu-
stion must be conveyed through a flexible
or rigid plastic pipe around 100 to 150
mm in diameter, and condensation must
be siphoned off at the foot of the pipe. The

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 8089912/13. 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 fitted, ancho-
red to the pipe segment with the screws
provided (fig. 9/a).
Maximum flow resistance must be no more
than 10 mm H2O (version 12) - 15 mm H2O
(version 25-30-35) (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.
2.8 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 solu-
tions, 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 provide
for proper earthing of the appliance.
2.9.1 Chronothermostat connection
Connect the chronothermostat as indicated
in the boiler electrical diagram (see figs. 11
e 11/a) after having removed the existing
bridge.
The chronothermostat to be used must be
Fig. 10
TABLE 3
Siting of terminal Appliances from 7 to 35 kW
(distances in mm)
A - below openable window 600
B - below ventilation opening 600
C - below eaves 300
D - below balcony (1) 300
E - from adjacent window 400
F - from adjacent ventilation opening 600
G - from horizontal or vertical soil or drain pipes (2) 300
H - from corner of building 300
I - from recess in building 300
L - from ground level or other treadable surface 2500
M - between two terminals set vertically 1500
N - between two terminals set horizontally 1000
O - from a surface facing without openings or terminals 2000
P - as above but with openings and terminals 3000
1) Terminals below a practicable balcony must be located in
such a way that the total path of the smoke from its outlet
point from the terminal to its outlet point from the external
perimeter of the balcony, including the height of possible
railings, is not less than 2000 mm.
2) When siting terminals, where materials that may be subject
to the action of the combustion 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.
