IMPORTANT
When turning the boiler on for the first time it is best to run the following checks:
–
Make sure there are no flammable li uids 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.
FONDERIE SIME S.p.A. located in Via Garbo 27 - Legnago (VR) - Italy declares that its hot water boilers, CE appro-
ved according to Gas Directive 90/396/CEE and e uipped with safety thermostat calibrated to maximum 110°C,
are exempt from PED Directive 97/23/CEE application field because they meet the re uisites foreseen in arti-
cle 1 comma 3.6 therein.

Installation is permanent and must exclu-
sively be performed by specialised and
ualified personnel, following all the
instructions and provisions included in
this manual.
Current regulations must also be met.
2.1 SUPPLY
“PLANET DEWY 0-120 BOX” heat modu-
les, inter-connectible by flange, are supplied
with an external pre-painted zinc-coated
laminate case. They are complete with
hydraulic separator, supply/return water
manifold fastening screws and gaskets and
se uence/cascade digestion unit cod.
8096311 supplied with “120-180-240
BOX” modules and cod. 8096312 supplied
with “300-3 0 BOX” modules.
Available separately:
– Safety kit to re uested according to
module fixture positions:
cod. 8101511 for right-hand fixtures
cod. 8101510 for left-hand fixtures.
– Additional safety valve kit code 8103825
for modules “300-3 0 BOX”
- Hydraulic separator box/safety kit cod.
8101517 (fig. 4)
– Polypropylene exhaust manifold kit for
indoor installation:
cod. 8102510 for “ 0 BOX” module
cod. 8102511 for “120 BOX” module
cod. 8102512 for “180 BOX” module
cod. 8102513 for “240 BOX” module
cod. 8102514 for “300 BOX” module
cod. 8102515 for “3 0 BOX” module
– Exhaust terminal cod. 8089530 for out-
door installations.
To electrically connect the modules and to
assemble the exhaust for indoor or outdoor
installations, see points 2.6, 2.7 and 2.10 in
this manual.
2.2 INSTALLATION
2.2.1 Indoors
“PLANET DEWY 0-120-180-240-300-
3 0 BOX” heat modules can be installed in
boiler rooms whose size and re uirements
meet current regulations.
Furthermore, vents, with surface areas at
least 3.000 s . cm or 5.000 s . cm for
gas with density over 0.8, must be installed
in the outer walls for room ventilation.
2.2.2 Outdoors
“PLANET DEWY 0-120-180-240-300-
3 0 BOX” heat modules can also be instal-
led outdoors with the specific exhaust for
single module cod. 8089530.
2.3 SYSTEM CONNECTIONS
To protect the heat system from damaging
corrosion, incrustation or deposits, after
installation it is extremely important to
clean the system using suitable products
such as, for example, Sentinel X300 or
X400. Complete instructions are provided

with the products but, for further informa-
tion, you may directly contact GE Betz.
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: 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 m3/h and gas
density must be taken into account.
System pipe sections must be able to gua-
rantee 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.
2.5 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. EXHAUST FOR OUTDOOR
INSTALLATION
The exhaust terminal for single module cod.
8089530 is re uired for this type of instal-
lation. For separately supplied accessory
assembly see fig. 5.

2.7 INDOOR INSTALLATION
EXHAUST KIT
Refer to fig. 6 and 6/a-b for this type of
installation.
The indicated solutions have the exhaust
manifold positioned both on the module’s
right and left and the use of extension cod.
8102522/23, supplied separately, is only
necessary when the hydraulic separator
box/safety kit cod. 8101517 is installed.
Figure 6/c for 6/d illustrates the elements
included in the polypropylene exhaust
manifold re uired for single and multiple
module installation, and the available acces-
sories to be used according to installation
type.

CONNECTIONS
Each module is supplied with a power cord
which, if replacement is re uired, must be
ordered from SIME.
230V – 50 Hz single phase voltage is
re uired using a fuse protected main swit-
ch 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.

Module are electrically connected to the 6-

To connect modules and power supply, see
diagram in fig. 7/a.

3.1 ELECTRONIC BOARD
Built according to Low Voltage directive
CEE 73/23 and powered at 230 Volt, via a
transformer it sends 24 Volt power to the
following components: gas valve, safety
thermostat, heating probe, water pressure
transducer and air pressure switch.
An automatic and continual modulation
system permits the boiler to adjust power
to the various system or user needs.
Electronic components are guaranteed to
operate in a temperature range from 0 to
+60°C.
3.1.1 Malfunctions
The led that signal errors and/or malfunc-
tions are indicated in fig. 14.
3.1.2 Devices
The electronic board is e uipped with the
following devices:
–“POT. RISC.” trimmer (10 fig. 15)
Adjusts maximum heating power.
To increase the value, rotate the trim-
mer clockwise, to reduce it, rotate the
trimmer counter-clockwise.
–“POT. ACC.” trimmer (6 fig. 15)
Trimmer to vary the gas valve ignition
pressure level (STEP). According to the
type of gas the boiler is designed for, the
trimmer must be adjusted to achieve a
burner pressure of approximately 6.5
mm H2O for methane gas and 9.5 mm
H2O for propane gas (G31).
To increase pressure, rotate the trim-
mer clockwise, to reduce it, rotate the
trimmer counter-clockwise. The slow igni-
tion pressure level can be set during the
first five seconds after the burner is lit.
After setting the ignition pressure level
(STEP) according to the type of gas,
make sure that the heating gas pressu-
re is still the previously set value.
–“ANN. RIT.” connector (5 fig. 15)
The electronic board is programmed,
during heating, with a technical burner
delay of about 90 seconds that is perfor-
med both at cold start and subse uent
ignitions. This is to prevent rapid ignitions
and shutdowns that could, in particular,
occur in systems with high load losses.
Each time the boiler restarts, after the
slow ignition, for about 1 minute it will run
at minimum modulation pressure before
moving to the set heating pressure. The
addition of a bridge will cancel both the
programmed technical delay and the
minimum pressure operating period at
ignition. In this case, the time between
shutdown and the next ignition will depend
on a 5°C differential detected by the hea-
ting probe (SM).
–DIP SWITCH (13 fig. 15)
For correct module operations, the dip
switches must be positioned as indicated
below:
–“Modureg Sel.” connector (14 fig. 15)
The bridge must always be off.
–“Albatros” connector (15 fig. 15)
The bridge must always be off.
It is only engaged in se uence/cascade
installations with several boilers.
WARNING: All the above operations must be
performed by authorised personnel,
otherwise the warranty shall be invalidated.

In se uence, perform wiring connections and
install the shunt box with regulator in the modu-
les indicated by the diagram in fig. 7/a.
