INSTALLATION
General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCOR-
DANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS
OF CURRENT LAW, THE PRESCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE
RULES OF PROPER WORKMANSHIP.
Place of installation
The boiler must be installed in a special room with ventilation openings towards the outside in confor-
mity with current regulations. If there are several burners or extraction units that can work together in
the same room, the ventilation openings must be sized for simultaneous operation of all the units. The
place of installation must be free of flammable objects or materials, corrosive gases, volatile substances
or dusts which, sucked by the burner fan, can obstruct the pipes inside the burner or the combustion
head. The room must be dry and not exposed to rain, snow or frost.
AIf the unit is enclosed in a cabinet or mounted alongside, a space must be provided for removing the
casing and for normal maintenance operations. In particular, after boiler installation with burner on the
front door, make sure the front door can open freely without the burner striking walls or other obsta-
cles.

Plumbing connections

The heating capacity of the unit must be previously established by calculating the building's heat re-
quirement according to the current regulations. The system must be provided with all the components
for correct and regular operation. It is advisable to install shutoff valves between the boiler and heating
system allowing the boiler to be isolated from the system if necessary.
BThe safety valve outlet must be connected to a funnel or collection pipe to prevent water spurting onto
the floor in case of overpressure in the heating circuit.
Otherwise, if the discharge valve cuts in and floods the room, the boiler manufacturer cannot be held
liable.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that
could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in and thecap. 5 symbols given on the
unit.
AThe unit is not supplied with an expansion tank; its connection must therefore be carried out by the
Installer. The pressure in the system, when cold, must be 1 bar.

IIn the presence of water harder than 25° Fr (1°F = 10ppm CaCO3), use suitably treated water in order
to avoid possible scaling in the boiler. Treatment must not reduce the hardness to values below 15°F
(Decree 236/88 for uses of water intended for human consumption).
Treatment of the water used is indispensable in case of very large systems or with frequent introduction
of replenishing water in the system.
BIf water softeners are installed at the boiler cold water inlet, make sure not to reduce the water hardness
too much, as this could cause early deterioration of the magnesium anode in the hot water tank.
Antifreeze system, antifreeze fluids, additives and inhibitors If it becomes necessary, it is permissible to
use antifreeze fluid, additives and inhibitors only if the manufacturer of these fluids or additives guaran-
tees they are suitable for this use and cause no damage to the heat exchanger or other components
and/or materials of the boiler unit and system. It is prohibited to use generic antifreeze fluid, additives
or inhibitors that are not expressly suited for use in heating systems and compatible with the materials
of the boiler unit and system.
