IMPORTANT
When turning the boiler on for the first time it is best to run the following checks:
–
Make sure there are no flammable liquids or materials in the boiler’s near vicinity.
– Make sure that electrical connections are correct and that the grounding wire is connected to a
good grounding system.
– Open the gas tap and check the seal on the fixtures including the burner.
– Make sure that the boiler is set to operate with the type of gas supplied.
– Make sure that the exhaust flue is free and/or correctly assembled.
– Make sure that any shutters are open.
– Make sure that the system was filled with water and that all air was drained.
– Make sure the distributor is not obstructed.
– Discharge any air in the gas pipes by using the pressure escape on the gas valve.

2.3 SYSTEM CONNECTIONS
To protect the heat system from dama-
ging corrosion, incrustation or deposits,
after installation it is extremely impor-
tant 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 cor-
rosion and deposits, the use of inhibi-
tors such as Sentinel X100 or Fernox
Protector F1 is recommended after cle-
aning the system.
It is important to check the concentration
of the inhibitor after each system modifi-
cation and during maintenance following
the manufacturer’s instructions (specific
tests are available at your dealer).
The safety valve drain must be con-
nected to a collection funnel to collect
any discharge during interventions.
WARNING: Failure to clean the heat
system or add an adequate inhibitor
invalidates the device’s warranty.
Gas connections must be made in accor-
dance with current standards and regu-
lations. 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.
System pipe sections must be able to
guarantee sufficient supply to cover
maximum demand, limiting pressure
loss between the meter and any utility
device no greater than 1.0 mbar for
second family gas (natural gas).
A sticker inside the module includes
identification and gas type data specific
to the module.
2.3.1 Condensation drain connection
A siphoned drain must be connected to
the civil drain by a pipe with minimum 5
mm per meter gradient for condensation
collection.
Only normal plastic civil drain pipes are
suitable to convey condensation to the
building’s sewer drain.
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.
2.5 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
FOR OUTDOOR
INSTALLATION (fig. 5)
The exhaust terminal for single module
code 8089530 is required for this type
of installation. For separately supplied
accessory assembly see fig. 5.

2.7 INDOOR INSTALLATION
EXHAUST KIT
(fig. 6 - 6/a - 6/b)
Refer to fig. 6 and 6/a-b for this type of
installation.
The indicated solutions have the exhaust
manifold (available separately) positio-
ned on the module’s to right.
It is however possible to move the
exhaust of the left by simply rotating the
manifold 180°.
NOTE: The kits are purposely treated
also to resist weathering when installed
outdoors.
In these cases the compensator and
safety device must be inserted in the
double container box code 8101527.

2.9 RS-485 BOARD (fig. 8)
Each module is supplied with the RS- 485
board which allows you to manage the
boilers in sequence/cascade.
The board is placed on the back of the
control panel.
2.9.1 MODBUS mode
(fig. 8/a)
This mode allows for MODBUS commu-
nication of at least two boilers in cascade
and is performed by requesting another
RS-485 board provided in the kit code
8092244.
ATTENTION: Communication will occur
only with the MASTER boiler, (boiler
with PAR 15 = 0), interpreting the casca-
de as a single heat capacity generator:
P CASCADE = P BOILER x No. BOILERS.
To install the second board, proceed as
follows:
- Remove the cover and electrical-
ly connect the second RS-485 board
equipped with lid to the RS-485 board
already installed in the MASTER boiler
(boiler with PAR 15 = 0) with the wired
connector provided in the kit.
CAUTION: Insert the wired connector

CONNECTIONS
Each module is supplied with a power
cord which, if replacement is required,
must be ordered from SIME.
230V – 50 Hz single phase voltage is
required using a fuse protected main
switch with at least 3 mm. between
contacts. Observe the L – N polarity and
grounding connection.
NOTE: SIME shall not be liable for any
damages to persons and things due to
lack of boiler grounding.

NOTICE: The external temperature probe (SE) must be connected to the
MASTER boiler and the cascade supply probe (SMC) to the SLAVE 1 boiler.
The SE, SMC probes and the RS-485 board connection cable are supplied
together with the modules in the probe kit code 8092250.
The RS-485 board for management in sequence/cascade is pla-
ced at the rear of the control panel of each individual module
as shown in the figure.
CONFIGURATION OF CASCADE PARAMETERS
Sequence/cascade installations must have the following INST
parameter set on all connected boilers:
PAR 15 = 0 for the first boiler (MASTER)
1 .... 7 for the other boilers (SLAVE)
(Avoid assigning the same number to SLAVE
boilers)
Set the following INST parameter if polypropylene smoke
collectors with a clapet valve are used in sequence/cascade
installations:
PAR 1 = 8 (for NATURAL GAS boilers)
16 (for PROPANE boilers)
To access the INST parameters, see point 3.3.
In addition, when the number of connected boilers in cascade is
more than two, parameter OEM A1 of the MASTER boiler must
be configured as well.
To access the OEM parameters press simultaneously the but-
tons (
