1) GENERAL INTRODUCTION
@ The equipment must be installed in compliance with the
regulations in force, following the manufacturer's instruc-
tions, by qualified personnel.
ө Qualified personnel means those having technical knowle-
dge in the field of components for civil or industrial heating
systems, sanitary hot water generation and particularly ser-
vice centres authorised by the manufacturer.
e Improper installation may cause injury to people and апі-
mals, or damage to property, for which the manufacturer
cannot be held liable.
e Remove all packaging material and inspect the equipment
for integrity.
In case of any doubt, do not use the unit - contact the supplier.
The packaging materials (wooden crate, nails, fastening devi-
ces, plastic bags, foamed polystyrene, etc), should not be left
within the reach of children, as they may prove harmful.
ө Before any cleaning or servicing operation, disconnect the
unit from the mains by turning the master switch OFF, and/
or through the cut-out devices that are provided.
ө Make sure that inlet or exhaust grilles are unobstructed.
e Іп case of breakdown and/or defective unit operation,
disconnect the unit. Make no attempt to repair the unit or
take any direct action.
Contact qualified personnel only.
Units shall be repaired exclusively by a servicing centre, duly
authorised by the manufacturer, with original spare parts.
Failure to comply with the above instructions is likely to impair
the unit's safety.
To ensure equipment efficiency and proper operation, it is
essential that maintenance operations are performed by quali-
fied personnel at regular intervals, following the manufactu-
rer's instructions.
e When a decision is made to discontinue the use of the
equipment, those parts likely to constitute sources of dan-
ger shall be made harmless.
e Іп case the equipment is to be sold or transferred to
another user, or in case the original user should move and
leave the unit behind, make sure that these instructions
accompany the equipment at all times so that they can be
consulted by the new owner and/or the installer.
e For all the units that have been modified or have options fit-
ted then original accessory equipment only shall be used.
e This unit shall be employed exclusively for the use for
which it is meant. Any other use shall be considered as
improper and, therefore, dangerous.
The manufacturer shall not be held liable, by agreement or
otherwise, for damages resulting from improper installation,
use and failure to comply with the instructions supplied by the
manufacturer.
2) SPECIAL INSTRUCTIONS FOR BURNERS
e The burner should be installed in a suitable room, with ven-
tilation openings complying with the requirements of the
regulations in force, and sufficient for good combustion.
e Only burners designed according to the regulations in force
should be used.
e This burner should be employed exclusively for the use for
which it was designed.
e Before connecting the burner, make sure that the unit
rating is the same as delivery mains (electricity, gas oil, or
other fuel).
ө Observe caution with hot burner components. These аге,
usually, near to the flame and the fuel pre-heating system,
they become hot during the unit operation and will remain
hot for some time after the burner has stopped.
When the decision is made to discontinue the use of the bur-
ner, the user shall have qualified personnel carry out the fol-
lowing operations:
a) Remove the power supply by disconnecting the power cord
from the mains.
b) Disconnect the fuel supply by means of the hand-operated
shut-off valve and remove the control handwheels from
their spindles.
Special warnings
e Make sure that the burner has, on installation, been firmly
secured to the appliance, so that the flame is generated
inside the appliance firebox.
e Before the burner is started and, thereafter, at least once a
year, have qualified personnel perform the following opera-
tions:
8) set the burner fuel flow rate depending on the heat input of
the appliance;
b) set the flow rate of the combustion-supporting air to obtain
a combustion efficiency level at least equal to the lower
level required by the regulations in force;
с) check the unit operation for proper combustion, to avoid
any harmful or polluting unburnt gases in excess of the
limits permitted by the regulations in force;
d) make sure that control and safety devices are operating
properly;
е) make sure that exhaust ducts intended to discharge the
products of combustion are operating properly;
f) on completion of setting and adjustment operations, make
sure that all mechanical locking devices of controls have
been duly tightened;
9) make sure that a copy of the burner use and maintenance
instructions is available in the boiler room.
e In case of repeated burner shut-downs, do not continue re-
setting the unit manually. Contact qualified personnel to
take care of such defects.
e The unit shall be operated and serviced by qualified per-
sonnel only, in compliance with the regulations in force.

3) GENERAL INSTRUCTIONS DEPENDING ОМ FUEL
USED
3a) ELECTRICAL CONNECTION
e For safety reasons the unit must be efficiently earthed and
installed as required by current safety regulations.
e Itis vital that all saftey requirements are met. In case of any
doubt, ask for an accurate inspection of electrics by quali-
fied personnel, since the manufacturer cannot be held lia-
ble for damages that may be caused by failure to correctly
earth the equipment.
ө Qualified personnel must inspect the system to make sure
that it is adequate to take the maximum power used by the
equipment shown on the equipment rating plate. In particu-
lar, make sure that the system cable cross section is ade-
quate for the power absorbed by the unit.
e No adaptors, multiple outlet sockets and/or extension
cables are permitted to connect the unit to the electric
mains.
e An omnipolar switch shall be provided for connection to
mains, as required by the current safety regulations.
ө The use of апу power-operated component implies obser-
vance of a few basic rules, for example:
% do not touch the unit with wet or damp parts of the body
and/or with bare feet;
% do not pull electric cables;
% do not leave the equipment exposed to weather (rain,
sun, etc.) unless expressly required to do so;
% do not allow children or inexperienced persons to use
equipment;
ө The unit input cable shall not be replaced by the user.
In case of damage to the cable, switch off the unit and contact
qualified personnel to replace.
When the unit is out of use for some time the electric switch
supplying all the power-driven components in the system (i.e.
pumps, burner, etc.) should be switched off.
3b) FIRING WITH GAS, LIGHT OIL OR OTHER FUELS
GENERAL
ө The burner shall be installed by qualified personnel and іп
compliance with regulations and provisions in force; wrong
installation can cause injuries to people and animals, or
damage to property, for which the manufacturer cannot be
held liable.
ө Before installation, it is recommended that all the fuel sup-
ply system pipes be carefully cleaned inside, to remove
foreign matter that might impair the burner operation.
ө Before the burner is commissioned, qualified personnel
should inspect the following:
a) the fuel supply system, for proper sealing;
b) the fuel flow rate, to make sure that it has been set based
on the firing rate required of the burner;
c) the burner firing system, to make sure that it is supplied for
the designed fuel type;
d) the fuel supply pressure, to make sure that it is included in
the range shown on the rating plate;
e) the fuel supply system, to make sure that the system
dimensions are adequate to the burner firing rate, and that
the system is equipped with all the safety and control devi-
ces required by the regulations in force.
ө When the burner is to remain idle for some time, the fuel
supply tap or taps should be closed.
SPECIAL INSTRUCTIONS FOR USING GAS
Have qualified personnel inspect the installation to ensure
that:
a) the gas delivery line and train are in compliance with the
regulations and provisions in force;
b) all gas connections are tight;
c) the boiler room ventilation openings are such that they
ensure the air supply flow required by the current regula-
tions, and in any case are sufficient for proper combustion.
e Do not use gas pipes to earth electrical equipment.
ө Never leave the burner connected when not in use. Always
shut the gas valve off.
e Іп case of prolonged absence of the user, the main gas
delivery valve to the burner should be shut off.
Precautions if you can smell gas
а) do not operate electric switches, the telephone, or any
other item likely to generate sparks;
b) immediately open doors and windows to create an air flow
to purge the room;
C) close the gas valves;
d) contact qualified personnel.
e Do not obstruct the ventilation openings of the room where
gas appliances are installed, to avoid dangerous conditions
such as the development of toxic or explosive mixtures.

Note: all the gas flow rates (Stm?/h) are referred to standard gas conditions: 1013 mbar pressure, 15? C temperature.
Flow rates are referred to G20 natural gas (nett calorific value, 34.02 MJ/Stm?); if G25 is used (n.c.v. 29.25 MJ/Stm?), flow rates
must be multiplied by 1.16 factor.
* Minimum pressure requested to get the maximum rate with any back-pressure in combustion chamber (referring to the perfor-
mance curves). The burner operates correctly also with lowest pressure only if these are enough to guarantee the necessary
gas rate.
