d
IT IS FORBIDDEN
– To expose the boiler to atmospheric
agents. These boilers can also be in-
stalled in partially covered areas, as
per EN 15502, with a maximum ambi-
ent temperature of 60 °C and a mini-
mum ambient temperature of - 5 °C.
It is recommended that the boiler is
installed below weathered roofs, on
the balcony or in a protected niche, to
protect it from exposure to weathering
agents (rain, hail and snow). The boiler
is equipped as standard with an anti-
freeze function.
– To block or reduce the size of the venti-
lation openings of the room where the
appliance is installed, if present.
– Remove the mains power and gas sup-
ply from the appliance if the external
temperature could fall below ZERO
(risk of freezing).
– To leave containers with flammable
substances in the room where the ap-
pliance is installed.
–To dispose of the packaging material
irresponsibly as it could be danger-
ous. Packaging must be disposed of as
specified by the legislation in force in
the country where the appliance will be
used.
– Do not install the boiler in special en-
vironments that may limit its optimum
operation (e.g. marine environment).
– To spray aerosols in the vicinity of this
appliance while it is in operation.
– To place articles on or against this ap-
pliance.
–To modify this appliance.

INSTALLER CHECKLIST
Please check the following prior to installation:
- The heating system is clean and has been properly flushed
out using a power flushing machine
- The system has been pressure tested and is leak free.
Locate and repair any leaks as required
- For systems with water content exceeding the maximum
system content (as indicated in the table), an additional
expansion vessel will need to be sized and fitted
- The boiler must be installed on a flat, solid surface
- If installing on a free standing bracket, a suitable weather
proof board must be installed to protect the boiler for the
elements
- Install a fire proof back board if installer on combustible
surfaces

1 DESCRIPTION OF THE APPLIANCE
1.1 Characteristics
Edea HM 40 are last generation condensing wall mounted boilers
which
Sime has produced for heating and domestic hot water
production. The model
40 i is designed for installation in rooms,
while model
40 e is designed specifically for outdoor installa-
tion, protected against atmospheric agents. The main elements
choices made by
Sime for the Edea HM 40 boilers are:
– the total pre-mix microflame burner combined with a steel
heat exchanger for heating and a rapid heat exchanger for
DHW
– the sealed combustion chamber which can be classified "Type
C" in relation to the room where the boiler is installed, de-
pending on the smoke outlet configuration adopted during
installation
– the electronic control and command circuit board with micro-
processor, for optimal management of the heating system and
modulation of up to 1:10 for the instant production of domes-
tic hot water. It allows for connecting room thermostats, an
auxiliary sensor for managing kits, and the external sensor.
The presence of the external sensor will make the boiler work
at a variable temperature, in other words, the temperature in
the boiler will vary in relation to the outdoor temperature, in
accordance with the optimal climatic curve selected during
the installation phase, resulting in considerable energy and
financial savings. Moreover, the command board has an inter-
nal connection for inserting an expansion board which is used
to control external relays.
Other special features of the
Edea HM 40 boilers are:
– the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the
threshold of the value set at parameter "PAR 10" and , if there
is an external sensor, if the external temperature falls below
the threshold of the value set at parameter "PAR 11"
– the anti-blocking function of the pump and diverter valve, this
activates automatically every 24 hours if no request for heat
has been made
– the chimney sweep function lasts 15 minutes and makes the
job of the qualified technician easier when measuring the pa-
rameters and combustion efficiency
–domestic hot water comfort function which allows the time
necessary for the hot water to become available to be reduced
and ensures that the temperature is stable
– screen display of the operating and self-diagnostic parame-
ters with error code display when the fault occurs. This makes
repair interventions easier and allows appliance operation to
be restored correctly.
1.2 Check and safety devices
The Edea HM 40 boilers are equipped with the following check
and safety devices:
– thermal safety thermostat 100°C
– 3 bar (300 kPa) relief valve
– heating water pressure transducer
– delivery sensor
– DHW sensor
– smoke flue gas probe
– return sensor.
NOTE: the proper fan operation of this boiler is checked elec-
tronically from the control panel. Then the use of an air pressure
switch is not required.
d
IT IS FORBIDDEN
To commission the appliance with safety devices
which do not work or which have been tampered with.
a
WARNING
Safety device may only be replaced by professional
qualified personnel using
Sime original spare parts.
1.3 Identification
The Edea HM 40 boilers can be identified by means of:
1 Packaging label: this is located on the outside of the packag-
ing and provides a code, the serial number of the boiler and
the bar code
2 Technical Data Plate: it is positioned on the outside of the
right side of the boiler and contains the technical and per-
formance data of the appliance and what is required by cur-
rent legislation.

1.8 Expansion vessel
The expansion vessel installed on the boilers has the following
characteristics:
Description U/M
Edea HM 40
40 i
- 40 e
Total capacity l10.0
Prefilling pressure kPa 100
bar 1.0
Useful capacity l6.0
Maximum system content (*) l140
(*) Conditions of:
Average operating temperature 70°C (with high tempera-
ture system 80/60°C)
Start temperature at system filling 10°C.
m
CAUTION
– For systems with water content exceeding the max-
imum system content (as indicated in the table) an
additional expansion vessel must be prearranged.
– The difference in height between the relief valve
and the highest point of the system cannot exceed
6 metres. If the difference is greater than 6 metres,
increase the prefilling pressure of the expansion
vessel and the system when cold by 0.1 bar (10 kPa)
for each meter increase.
