2. Installation

2.1 General Instructions

BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH
ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRE-
SCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.

2.2 Place of installation

The boiler must be installed in a special room with ventilation openings towards the outside in conformity with current
regulations. If there are several burners or extraction units that can work together in the same room, the ventilation open-
ings 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.
If the unit is enclosed in a cabinet or mounted alongside, a space must be provided for removing the casing
A
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 obstacles.

2.3 Plumbing connections

The heating capacity of the unit must be previously established by calculating the building's heat requirement according
to current regulations. The system must be provided with all the components for correct and regular operation. It is ad-
visable to install on-off valves between the boiler and heating system allowing the boiler to be isolated from the system
if necessary.
B
The 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 prop-
er operation of the unit.
Carry out the relevant connections according to the diagram in cap. 4 "Technical data and characteristics" and the sym-
bols given on the unit.
Water system characteristics
In 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.
B
If 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
The boiler is equipped with an antifreeze system that turns on the boiler in heating mode when the system delivery water
temperature falls under 6°C. The device will not come on if the electricity and/or gas supply to the unit are cut off. If it
becomes necessary, it is permissible to use antifreeze fluid, additives and inhibitors only if the manufacturer of these
fluids or additives guarantees they are suitable for this use and cause no damage to the heat exchanger or other com-
ponents and/or materials of the boiler unit and system. It is prohibited to use generic antifreeze fluid, additives or inhib-
itors that are not expressly suited for use in heating systems and compatible with the materials of the boiler unit and
system.
