protect it from exposure to weathering

agents (rain, hail and snow). The boiler

is equipped as standard with an anti-

freeze function.

d

IT IS FORBIDDEN

– 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.

This manual is organized as follows.

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

- The ﬁxing method and the wall structure must be sufﬁcient

to hold weight of the boiler.

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

The

Brava Slim HE 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:

this is located inside the front panel of

the boiler and provides the technical speciﬁcation, appliance

performance and any other information required by law.

CAUTION

Tampering with, removing or failing to display the

identiﬁcation plate or carrying out any other operation

which does not allow safe identiﬁcation of the product

or which may hinder installation and maintenance op-

erations.
