ORIGINAL INSTRUCTIONS

This boiler may require 2 or more operatives to move it into its installation site, remove it from its packaging
and during movement into its installation location. Manoeuvring the boiler may include the use of a sack truck
and involve lifting pushing and pulling.
Caution should be exercised during these operations.
Operatives should be knowledgeable in handling techniques when performing these tasks and the following
precautions should be considered:
– Grip the boiler at the base
– Be physically capable
– Use personal protective equipment as appropriate e.g. gloves, safety footwear.
During all manoeuvres and handling actions, every attempt should be made to ensure the following unless
unavoidable and/or the weight is light.
– Keep back straight
– Avoid twisting at the waist
– Always grip with the palm of the hand
– Keep load as close to the body as possible
– Always use assistance
WARNING
Caution should be exercised when performing any work on this appliance.
Protective gloves and safety glasses are recommended.
– Avoid direct contact with sharp edges.
– Avoid contact with any hot surfaces.
NOTICE
Please be aware that due to the wet testing of the appliance, there may some residual water in the hydraulic
circuit.
– Protect any surfaces, carpets or floorings.
– Use a suitable container to catch any water that escape when removing the protective caps from the
connections.

IMPORTANT
Prior to switching on the boiler for the first time, check the following:
– 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 connected
to a good earthing system.
– Ensure that tightness and let by test have been conducted, including the internal gas pipe work.
– 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 isolation valves are open.
– Make sure that the system is filled with water and is thoroughly vented.
– Check that the circulating pump is not jammed.
– Purge the gas supply pipe work.
– Ensure that the checklist is filled in when the commissioning has been completed.

2.2 INSTALLATION
2.2.1 Indoors
MURELLE EQUIPE 140 BOX ErP heat
modules can be installed in boiler rooms
whose size and requirements meet cur-
rent regulations.
VENTILATION
The following is provide for your guid-
ance 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.
Ventilation requirements for Murelle HE
70 R ErP boilers and cascade systems.
BS6644 has a requirement that the tem-
peratures in a room or compartment do
not exceed certain levels:
25°C at floor level (0-100 mm)
32°C at mid level (1.5 M above the floor
level)
40°C at ceiling level (0-100 mm from ceil-
ing)
Installed as a class B appliance (open
flued).
Installed in a room
High level (within 15% of the room height
from ceiling) - 2 cm²/KW of net heat input
Low level (low as possible within 1 metre
from floor natural gas, 250 mm LPG)– 4
cm²/KW of net heat input

Installed in a compartment or enclosure
High level (within 15% of the room height
from ceiling) - 5 cm²/KW of net heat input
Low level (low as possible within 1 metre
from floor natural gas, 250 mm LPG) – 10
cm²/KW of net heat input.
A single generator (63KW net input) would
require 630 cm² at high level and 1260 cm²
at low level.
2.2.2 Outdoors
MURELLE EQUIPE 140 BOX ErP heat mod-
ules can also be installed outdoors with
the specific exhaust for single 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
accordance with BS 7593. Sime Ltd recom-
mend only the use of Fernox products for
the flushing and final treatment of the sys-
tem water. This is particularly important
in hard water areas.It is recommended
that the inhibitor concentration is checked
at installation, system modification and
at every service in accordance with the
manufacturers instructions. Test kits are
available from inhibitor stockist.
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 m
3
/h and gas den-
sity must be taken into account.
System pipe sections must be able to
guarantee sufficient supply to cover maxi-
mum 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 sup-
plied 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.

of installation. For separately supplied
accessory assembly see fig. 5.
2.7 INDOOR INSTALLATION
EXHAUST KIT (fig. 6)
Refer to fig. 6 for this type of installation.
The indicated solutions have the exhaust
manifold positioned both on the modules.
It is however possible to move the exhaust

NOTE: The kits are purposely treated also
to resist weathering when installed out-
doors.

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
contacts. 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
provide for proper earthing of the appli-
ance.

CONFIGURATION OF CASCADE PARAMETERS
Sequence/cascade installations must have the following
INST parameter set on all connected generators:
PAR 15 = 0 for the first generator (MASTER)
1 .... 7 for the other generators (SLAVE)
(Avoid assigning the same number to SLAVE
generators)
Set the following INST parameter if polypropylene smoke
collectors with a clapet valve are used in sequence/cascade
installations:

To access the INST parameters, see point 3.3.
In addition, when the number of connected generators
in cascade is more than two, parameter OEM A1 of the
MASTER generator must be configured as well.

2.11.3 Room Thermostat and/or Timer
(clean contact)
The heating demand can be controlled
by a thermostat and/or timer (TA) con-
nected to CN6 terminals 7-8 (see fig
11), after having removed the existing
bridge. The control being used must be
of a class conforming to the standard EN
607301 (clean electrical contact).
2.11.4 Remote control SIME HOME
connection (optional)
The heating demand can be controlled
by use of remote control unit SIME
HOME (code 8092280/81)
The remote control unit allows for com-
plete control, except lockout reset.
The generator will display CR.
For installation and use of the control
follow the instructions in the package.
NOTE, Ensure PAR 10 set to 1 (PAR 10
= 1)
2.11.5 External Sensor (8094101)
An external sensor (code 8091401) can
be connected, which can automatically
regulate the flow temperature value of
the cascade delivery according to the
external temperature.
For installation follow the instructions
in the package. It is possible to make
corrections to the values by adjustment
of PAR 11.
2.11.6 Heat Demand by 230v
The heat demand can be controlled by
230v applied to terminal 14 of CN7, and
removal of the bridge on CN6 terminals
7 & 8.
2.11.7 BMS (Building Management
Systems)
The cascade of generators can be con-
trolled by a BMS signal, and should be
connected as shown in fig 11.
Set PAR 14 according to the maximum
(10v) flow temperature required.
