2.2 INSTALLATION
2.2.1 Indoors
“MURELLE EQUIPE 220-330-440-550-
660 BOX ErP” heat modules can be
installed in boiler rooms whose size and
requirements meet current regulations.
VENTILATION
The following is provide for your guid-
ance only, and assumes the ventila-
tion 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
110 R ErP boilers and cascade systems.

12
BS6644 has a requirement that the
temperatures 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-
660 BOX ErP” heat modules 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
recommend only the use of Fernox prod-
ucts for the flushing and final treatment
of the system 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
system or add an adequate inhibitor
invalidates 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
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 max-
imum demand, limiting pressure loss
between the meter and any utility device
no greater than 1.0 mbar for second fam-
ily gas (natural gas).
A sticker inside the module includes identifica-
tion and gas type data specific to the module.
2.3.1 Condensation drain connection
The condensate drain must be con-
nected 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.
2.4 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.
2.5 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.

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.
