ENERGY TOP W 70

2. Installation

2.1 General Instructions

THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLIANCE WITH ALL THE IN-
STRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE NATIONAL AND
LOCAL REGULATIONS, AND THE RULES OF PROPER WORKMANSHIP.
ENERGY TOP W 70 is a high-efficiency heat generator arranged to operate alone or in cascade (bank). When two or
more generators ENERGY TOP W 70 are installed in cascade with the original kits FERROLI, respecting the prescrip-
tions of this manual, they can be considered as a single heat generator of total power equal to the sum of the powers
of all the units connected in cascade.
All the requirements of the current standards and regulations applicable to this "equivalent" generator with total heating
capacity must be met. In particular the place of installation, safety devices and fume exhaust system must be adequate
for the total heating capacity of the bank of units.
In fact, each ENERGY TOP W 70 is a complete and independent heat generator, equipped with its own safety devices.
In case of overtemperature, a lack of water or no circulation in the unit, the protection devices cause the unit to switch
off or shut down, preventing it from working.
The installation instructions given in the following paragraphs concern both single units and connection in cascade.

2.2 Place of installation

The combustion circuit is sealed with respect to the place of installation and therefore the unit can be installed in any
room. However, the place of installation must be sufficiently ventilated to prevent the creation of any dangerous condi-
tions in case of even small gas leaks. This safety precaution is required by EEC Directive no. 90/396 for all gas-fired
units, including those with a so-called sealed chamber.
The unit can also work with air drawn from the installation room (B type). In this case, the room must be provided with
adequate ventilation, according to current regulations.
Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. The room
must be dry and not subject to freezing.
The boiler is arranged for wall installation. Wall fixing must ensure a stable and effective support for the generator.

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 proper and regular operation. In par-
ticular, provide for all the protection and safety devices required by current regulations for the complete modular gener-
ator. They must be installed on the hot water circuit delivery piping, immediately downstream of the last module, within
a distance of 0.5 m, with no shutoff devices in between. The unit is not supplied with an expansion tank; its connection
must therefore be carried out by the Installer.
B
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.
B
Carry out the relevant connections according to the diagram in sec. 4.1 and the symbols given on the unit.

If the unit is enclosed in a cabinet or mounted alongside, a space must be provided for removing the casing
and for normal maintenance operations
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.
A filter must be also installed on the system return piping to prevent impurities or sludge from the system clog-
ging and damaging the heat generators.
The filter MUST be installed when replacing generators in existing systems. The manufacturer declines any
liability for damage caused to the generator by failure to install or inadequate installation of this filter.
