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.

1.6 TECHNICAL DATA PLATE (fig. 3/a)

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
- In the rooms where “type B” boilers are
installed, the air required for correct
combustion of the gas consumed by the
appliance must be able to flow in. It is
therefore necessary to make openings
that cannot be blocked in the outer walls,
which must be at least 6 cm2 for every kW
of thermal capacity installed and with, in
any case, a minimum of 100 cm2.
- Boilers are suitable for functioning in a
partially protected place, as according to
EN 15502, with maximum environmen-
tal temperature of 60°C and minimum
of -5°C. We recommend installation of
these boilers under the protruding slope
of a roof, on a balcony, or in a pro-
tected niche, always providing they are
not directly exposed to adverse weather
(rain, hail, snow). The boilers are pro-
vided already equipped with anti-freeze
functions.
- In existing buildings, this natural intake
water heater must only be connected to a
hot-air device shared by different homes
to expel combustion residues from the
room where the water heater is installed.
The water heater draws air required for
combustion directly from the room, and
is equipped with a wind-proof chimney.
Due to poorer efficiency, any other use
of this water heater is to be avoided as
it would result in higher power con-
sumption and higher operating costs (EU
REGULATION No. 813/2013).
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, howe-
ver, 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 COMPLEMENTARY ACCESSORIES
To facilitate connecting the boiler to the
system, the following accessories can be
supplied on request, complete with instruc-
tions for assembly:
- Installation plate code 8075438.
- Curvette and gas taps/sanitary water
output set code 8075418.
- Taps kit code 8091806.
- Kit of couplings for replacing wall-hung
boilers of other makes code 8093900.
- Mixed area kit ZONA MIX code 8092234.
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 further informa-
tion, 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 sup-
plied 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 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.
2.5 SYSTEM FILLING (fig. 4)
Filling of the boiler and the system is done
by the system filling (11).
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.
Should the pressure have risen well above
the limit expected, discharge the over pres-
sure by opening the pressure-relief valve.
2.5.1 Emptying the system (fig. 4)
Use the drain tap to empty the system (7).
Turn off the boiler before doing this.
2.6 FLUES/CHIMNEYS
A chimney or flue for the evacuation of the
combustion products into the atmosphere
must correspond to the requisites prescri-
bed by the laws in force.
2.11 ELECTRICAL WIRING
If you must replace the electric power cable
supplied with the boiler, order it exclusively
from Sime.
The power supply must be single-phase
230V - 50 Hz through a main switch pro-
tected by a fuse with a distance of at least 3
mm between contacts.
The boiler must be connected with an effi-
cient grounding system. SIME shall not be
held liable for injury or damage resulting
from failure to ground the boiler.
ATTENTION: Before every intervention on
the boiler, cut off the electricity supply by
means of the main switch of the system,
since even if the boiler is “OFF”, the elec-
trical panel remains connected to the elec-
tricity.
2.11.1 Chronothermostat connection
Connect the chronothermostat as indica-
ted in the boiler electrical diagram (see
paragraph 2.12) 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).
2.11.2 Remote control SIME HOME
connection (optional)
The boiler is designed for connection to a
remote control unit SIME HOME, supplied
on request (code 8092280/81).
The remote control unit SIME HOME allows
for complete 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).
2.11.3 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.

electronic systems
Some examples are given below of boiler
systems combined with different electronic
systems. Where necessary, the parameters
to be set in the boiler are given. The elec-
trical connections to the boiler refer to the
wording on the diagram (fig. 13).
