3.1 Installation standards
This boiler must be installed in compliance
with current laws and standards, which
are taken as being an integral part of this
booklet.
3.2 Installation
3.2.1 Packaging
The boilers are supplied packed in a
strong cardboard box on a wooden
pallet. On removing the cardboard box,
make sure that the boiler is complete.
The packing materials can be recycled.
Dispose of them via specific waste
collection sites.
Keep the packing out of the reach of
children, as, by its very nature, it may
constitute a source of danger.
The Manufacturer accepts no
responsibility for damage to people,
animals, or property due to failure to
observe the instruction above.
The pack contains a packet in which you
will find the installation, operation, and
maintenance manual.
3.2.2 Choosing where to install the
boiler
The following must be taken into account
when choosing where to install the
boiler:
• It is advisable to leave at least 50 cm on
each side of the boiler to facilitate future
maintenance.
• Do not install in damp or dusty rooms.
• The boiler room must not be accessible
to outsiders, children, or animals.
3.2.3 Installing the boiler
Before connecting the boiler to the
piping for the hot water and heating
systems, clean the piping carefully to
eliminate any metal residue left during
working and welding, and any oil or
grease that may be left and that could
damage the boiler or alter its operation if
it reaches the boiler.
NB: Do not use solvents, as these could
damage the components.
The Manufacturer accepts no
responsibility for damage to people,
animals, or property due to failure to
observe the instructions above.
To install the boiler proceed as follows:
• Remove the galvanised plate on the
lower back part of the boiler.
• Unscrew the four screws which block
the brackets fixing the boiler to the
timber pallet (Fig. 5)
• Remove the boiler from the pallet
without damaging it.
• Put spacers between the floor and the
boiler’s feet if necessary, to make the
installation stable.
• Connect the boiler to the system’s
delivery and return pipes.
• Remember that the plumbing system
must include all the safety and control
elements required in terms of current
standards (safety valve, water pressure
switch, heat discharge valve, pressure
gauge, etc.).
• Couple the boiler to the flue.
• Connect to the electrical system of the
boiler: the ambient thermostat, the
heating pump, and the heating water
pressure switch.
• Connect to the electrical mains.
3.2.4 Ventilation of boiler room
The boilers have open combustion
chambers and are designed for being
connected to a flue gas chimney.
The combustion-supporting air is drawn
directly from the room in which the boiler
is installed.
It is obligatory that the boiler be installed
in an adequate room in terms of the
current standard, which is taken as an
integral part of this booklet.
3.2.5 Flue gas discharge system
The BALI boilers are fitted with a flue gas
discharge coupling that is suitable for
connecting to a flue gas chimney with a
diameter as specified in the technical
data tables.
Current standards must be complied
with when discharging flue gas into the
atmosphere, and these standards are
taken as being an integral part of this
booklet.
The flue gas ducts from the boiler are to
be connected to a flue gas discharge
system formed as indicated in current
standards, which are taken as being an
integral part of this booklet.
The following obligatory requirements
for flue gas chimney and flue gas ducts
must be kept in mind:
• They are to be of a diameter not less
than that on the boiler outlet.
• They are to be made of impermeable
material that can withstand the flue gas
temperature and related acid condensate.
• They are to have low thermal
сonductivity, sufficient mechanical
strength, be properly sealed, and of a
calculated height and cross-section.
• The vertical inclination (flue gas duct)
and section are to be constant, without
any bottlenecks.
• Where horizontal flues sections have to
be used, these must be at an incline of at
least 5%.
• The end of the flue pipe is to be such
that it can ensure efficient, constant
evacuation of flue gas under any weather
conditions.
• The end section of the flue pipe is to be
at least 0,5 m above any adjacent
structure within a 5 m radius.
