VENTILATION
The following is provide for your guidance
only, and assumes the ventilation air is
taken directly from outside. The sizes of the
vents may need to be increased in respect
of other appliances installed in the same
area, and seasonal use. Take care that the
position of low level vents would not subject
to adverse weather conditions, ie flooding.

BS6644 has a requirement that the tem-
peratures in a room or compartment do
not exceed certain levels:
25°C at floor level(0-100mm)
32°C at mid level (1.5M above the floor level)
40°C at ceiling level (0-100mm from ceiling)
Installed as a class B appliance (open
flued).
Installed in a room
High level (within 15% of the room height
from ceiling) - 2cm²/KW of net heat input
Low level (low as possible within 1 metre
from floor natural gas, 250mm LPG)–
4cm²/KW of net heat input
A single generator (120KW net input)
would require 240cm² at high level and
480cm² at low level.
Installed in a compartment or enclosure
High level (within 15% of the room height
from ceiling) - 5cm²/KW of net heat input
Low level (low as possible within 1 metre
from floor natural gas, 250mm LPG) –
10cm²/KW of net heat input.
A single generator (120KW net input)
would require 600cm² at high level and
1200cm² at low level.
2.2.2 Outdoors
“MURELLE EQUIPE 220-330-440-550
BOX” heat modules can also be installed
outdoors with the specific exhaust for sin-
gle module code 8089530.
2.3 SYSTEM REQUIREMENTS
The heating system should be flushed prior
to the connection of the heating modules.
The system should be treated in accord-
ance with BS 7593. Sime Ltd recommend
only the use of Fernox products for the
flushing and final treatment of the system
water. This is particularly important in hard
water areas.
It is recommended that the inhibitor con-
centration is checked at installation, system
modification and at every service in accord-
ance with the manufacturers instructions.
Test kits are available from inhibitor stock-
ist.
WARNING: Failure to clean the heat sys-
tem or add an adequate inhibitor invali-
dates the device’s warranty.
Gas connections must be made in accord-
ance with current standards and regula-
tions. When dimensioning gas pipes from
the meter to the module, both capacity vol-
ume (consumption) in m3/h and gas den-
sity must be taken into account.
System pipe sections must be able to guar-
antee 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 iden-
tification and gas type data specific to the
module.
2.3.1 Condensation drain connection
The condensate drain must be connected
to the civil drain by a pipe with minimum 5
mm per meter gradient for condensation
collection.
Only stainless steel or plastic pipes are
suitable to convey condensate.
2.3.2 Filter on the gas pipe
The gas valve on each generator 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 acces-
sory 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) positioned
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 out-
doors.
In these cases the compensator and safe-
ty device must be inserted in the double
container box code 8101527.

2.9 RS-485 BOARD (fig. 8)
Each generator is supplied with the RS-
485 board which allows you to manage the
boilers in sequence/cascade (see fig 8).
The board is placed on the back of the con-
trol panel.
2.9.1 MODBUS mode
(fig. 8/a)
This mode allows for MODBUS communica-
tion 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 generator, (gen-
erator with PAR 15 = 0), interpreting
the cascade as a single heat capacity
generator:
P CASCADE = P GENERATOR x No. GENERATORS.
To install the second board, proceed as
follows:
- Remove the cover and electrically con-
nect 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
with caution.
- Set the DIP SWITCH of the new board in
MODBUS mode.
- Close the lid of the second board.
- Choose the communication configuration
suited to the MODBUS network (PAR 17
INST) according to Table PAR 17 INST.

MODBUS BOILER VARIABLES LIST
Setpoint CH zone 1.
If you receive a value out of range so the
value isn’t received and the boiler tempe-
rature control is maintained of fixed point
or a temperature curve.
Setpoint CH during ACS preparation
(for PAR 66 installer parameters)
If you receive a value out of range the
value isn’t received and it is used the
boiler value regulation.
Setpoint ACS.
If you receive a value out of range the
value isn’t received and it is used the
boiler value regulation.
External value of temperature by MobBus.
If you receive a value out of range the value isn’t
received. In case of conflict the boiler will give
priority to the value of the probe connected to it.
Slope of heating curve of zone 1
(it is used instead of the curve set in the boiler).
If you receive a value out of range the value isn’t
received and it is used the boiler heating curve.
Shift value of room zone 1 set
(it is used instead of the shift set in the boiler).
If you receive a value out of range the value isn’t
received and it is used the boiler heating curve.

CONNECTIONS
Each module is supplied with a power cord
which, if replacement is required, it must
be replaced with one of similar type and
dimensions.
230V – 50 Hz single phase voltage
is required using a fuse protected main
switch with at least 3 mm. between con-
tacts. Observe the L – N polarity and
grounding connection. Each generator
should be fused at 3 A.
NOTE: Sime declines all responsibility for
injury or damage to persons, animals or
property resulting from the failure to pro-
vide for proper earthing of the appliance.
