1. Precautions
STEPS TO BE TAKEN IN CASE OF DANGER

Close fuel supply disconnect unit from mains using emergency stop or main switch (outside of the boiler room).

Use suitable fire extinguishers to extinguish flames.

Occurrence of gas smell (gas units)
- Ventilate the affected rooms thoroughly by opening doors and windows.
- Do not use any electronic devices (mobile phone, etc.).
- Do not activate any electrical contacts (light, motor, lift, doorbell, etc.).
- Do not ignite matches or lighters, and do not smoke.
- Call the gas board or heating engineer.
PACKAGING

After removing all packaging materials, check the contents to
make sure that no damage has occurred during shipping.
When in doubt, do not use the apparatus and contact the
supplier.

The packaging materials are to be disposed of properly.
THE BOILER UNIT

Smooth boiler performance and manufacturer’s guarantee are
dependent upon adherence to the boiler installation, operation
and maintenance instructions contained in this booklet.

Never permit children or unauthorized persons to tamper with
the equipment.

The unit must be used only for its expressed application. All
other uses are considered dangerous.

The burner's minimum and maximum delivery settings, all
pressures and temperatures must all be contained in the
range stipulated in this manual.

Modification of the equipment in order to alter its performance
or applications prohibited.

Do not open or tamper with components of the unit other than
those parts of the unit that are subject to maintenance
operations.

Never touch the hot parts of the unit; these parts (flue gas
conduit, sight glass, burner parts, etc.) may remain hot for
quite some time after the burner has switched off.

Never touch the unit with wet parts of the body or without
wearing shoes.

When the unit is not to be used for a longer period, the main
power switch on the electrical control panel must be switched
off and the manual valve on the unit fuel supply line must be
closed.

The device contains components made of synthetic silicon
mineral fibers (ceramic and glass fibers, insulation wool).
These components must be disposed of appropriately at the
end of their life cycle. Local regulations must be observed.
INSTALLATION AND SETTINGS

The installation and calibration of the unit must be performed
exclusively by qualified personnel in conformity with existing
regulations and the indications provided in this Manual.
THE BOILER ROOM

The boiler room must be lockable and it's external air openings
must conform to the norms prevailing locally. When in doubt
regarding air circulation, measure the CO
2
count with the
burner operating at its maximum delivery and the room
ventilated only by the burner ventilation air openings and a
second time with the door open. The CO
2
count measured in
both cases must not differ. Should there be more than one unit
in the same room, this test must be performed with all the
equipment operating simultaneously.

Never obstruct the boiler room's air openings, the burner fan
suction opening, and any air ducts and ventilation.

The equipment must always be protected against rain, snow,
and freezing conditions.

The boiler room must be kept clean and free of volatile
substances that may be sucked into the fan and clog the inner
burner or combustion head air ducts.

The combustion air must be free of halogens (chlorine and
fluorine compounds). If there is any doubt, the quality of the
combustion air must be ensured with an external air intake.
ELECTRICAL INSTALLATION

Electrical connections must be made exclusively by qualified
personnel and all prevailing electrical regulations must be
scrupulously observed.

Make sure that the electrical power supply used for connection
conforms to the specifications indicated on the rating plate and
in this manual.

The unit must be correctly connected to an efficient ground
system in conformity to the prevailing norms and checked and
controlled for efficiency by qualified personnel when in doubt.

Never confuse neutral wires with phase wires.

The unit must be hooked up to the electrical network with a
plug-socket connection that is such as to prevent inversion of
phase and neutral. Install a master switch for the heating plant
as requested by existing legislation.

The entire electrical system, and all cable sections in
particular, must be adequate to deliver the maximum absorbed
power value indicated on the equipment's rating plate and in
this manual.

If the mains power cable is found to be defective, it must be
replaced only by qualified personnel.

Never stretch power supply cables and keep them well away
from sources of heat.
FUEL

The unit must be fed with the type of fuel for which it has been
preset as indicated on the rating plate.

The fuel pressure must be according to the values listed in the
burner manual.

The fuel line that feeds the unit must be sized according to the
requirements of local regulations and the prescriptions in the
burner manual. The line must be perfectly sealed. The fuel
supply line must also be equipped with all the control and
safety mechanisms required by local regulations in force. The
line must be free from all impurities; take particular care that
foreign matter does not enter the line during installation.

Oil:
- The light oil storage tank must be adequately protected
against penetration of impurities and water. The fuel tank
must be kept full of fuel during the summer in order to
avoid the condensation of humidity. Clean the tank
carefully before filling. Beware not to overfill the tank.
- Both the tank and the unit fuel supply line must be
protected from frost.
- Oil consumption and tank unit must be checked regularly,
in order for leaks to be detected in good time.

Gas:
- The gas line must be checked for leakage during
commissioning and after each disconnection.
MALFUNCTION

If the unit stops working and goes into lock-out and does not
resume operation after two or three manual lock-out reset
attempts, disconnect the power supply, do not attempt to
repair, and contact a qualified specialist.

All repairs required must be performed exclusively at a
technical servicing and/or technician centre authorized by the
manufacturer using original spare parts only. Failure to
observe the above may compromise the reliability and safety
of the equipment.

Any failure or damage resulting from improper use or
intentional damage will relieve the manufacturer from any
guarantee obligation.
MAINTENANCE

Maintenance must be performed by qualified personnel
regularly or at least once a year.

Prior to performing any maintenance operations, switch off the
power supply by using the main switch and cut off the fuel
supply as well.

Only parts indicated by the manufacturer in the Spare Parts
Catalogue may be replaced.

In order to avoid all types of health hazards, suitable clothing
and a protective mask must be worn for work on or with
components made of synthetic silicon mineral fibers (ceramic
and glass fibers, insulation wool).
