1 DESCRIPTION OF THE APPLIANCE
1.1 Characteristics
Brava Slim HE 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 in-
stallation, protected against atmospheric agents. The main el-
ements choices made by
Sime for the Brava Slim HE 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, with respect to the room
where the boiler is installed
– the command and control microprocessor electronic board
provides efficient management of both heating and hot wa-
ter production. It can also be connected to a remote control
with an Open Therm protocol or to room thermostat and/or
external sensor. If connected to an external sensor, the boiler
temperature varies on the basis of the external temperature
according to a selected optimal climatic curve providing sig-
nificant energy and economic savings.
Other special features of the
Brava Slim HE 40 boilers are:
– use of a smoke probe to control the relative temperatures. If
the temperature exceeds 110°C the boiler will shut down in
safety status, requiring intervention of the Technical Service
department of qualified professional personnel
– 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 Brava Slim HE 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.
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.

WARNING
Safety device may only be replaced by professional
qualified personnel using
Sime original spare parts.
1.3 Identification

CAUTION
These minimum clearances must be maintained
also in consideration of outdoor installations in
confined spaces (e.g. alcoves).
2.5 New installation or installation of a re-
placement appliance
When Brava Slim HE 40 boilers are installed on old systems or
systems requiring updating, it is recommended the installer
checks with appliance supplier for advice:
– the connecting flue pipe is suitable for the combustion tem-
perature of the appliance, calculated and manufactured in
compliance with Standards, current editions, that it is as
straight as possible, air tight, isolated, with no obstructions or
restriction and that it has appropriate condensate collection
and evacuation systems
– the electrical system has been manufactured in compliance
with specific Standards and by professionally qualified per-
sonnel
–the fuel delivery line and the tank (UNIVERSAL LPG) comply
fully with specific Standards
– the expansion vessel ensures total absorption of the fluid di-
lation in the system
–the pump flow-head performance is sufficient for the system
characteristics
– the system is clean, free of any sludge, deposits, de aerated
and air tight. For system cleaning, please refer to the relevant
paragraph.
m
CAUTION
Gas pipe sizing, flue installation and appliance ven-
tilation must comply with AS/NZS 5601 and AS/NZS
3500.4 “Water piping installation".
d
IT IS FORBIDDEN
Do not install the boiler in special environments that
may limit its optimum operation (e.g. marine environ-
ment).
2.6 Cleaning the system
Before installing the appliance on a newly constructed system
or replacing a heat generator on an existing system, it is im-
portant that the system is thoroughly cleaned to remove sludge,
slag, dirt, residue etc.
Before removing an old heat generator from an existing system,
it is recommended that the user:
– puts a descaling additive into the water system
– allows the system to work with the generator active for a few days
– drains the dirty water from the system and flushes the system
with clean water once or more than once.
If the old generator has already been removed or is not availa-
ble, replace it with a pump to circulate water in the system and
then proceed as described above.
Once cleaning operations have been carried out and before
installing the new appliance, it is recommended that a fluid is
added to the water system to protect it from corrosion and de-
posits.
m
CAUTION
– For further information on the type of additive and
usage, please contact the appliance manufacturer.
– Please remember that you
MUST install a Y filter
(not supplied with the appliance) on the heating sys-
tem return (R).
2.7 Water system treatment
When filling and restoring the system it is good practice to use
water with:
– aspect: clear if possible
– Ph: 6÷8
– hardness: < 25°f.
If the water characteristics are different from those indicated, it
is recommended that a safety filter is used on the water deliv-
ery pipe to retain impurities, and a chemical treatment system
to protect against possible deposits and corrosion which could
affect boiler operation.
If the systems are only low temperature systems, it is recom-
mended that a product is used to prevent the development of
bacteria.
In any case, please refer to and comply with the legislation and
specific technical standards in force in the country where the
appliance will be used.
2.8 Boiler installation
Brava Slim HE 40 boilers leave the factory with a template for
installation onto a solid wall.
For installation:
– remote the front panel (only on model
Brava Slim HE 40 e )
– place the steel sheet template (2) (if supplied) on the wall (1)
– make the holes and insert the expansion plugs (3)
– hook the boiler onto the plugs.
