ENERGY TOP W 70 - W 80 - W 125

If the Remote Timer Control (optional) is connected to the boiler, the above ad-
justments are managed according to that given in table 1.

Table. 1

Plumbing system pressure adjustment

The filling pressure with the system cold must be approx. 1.0 bar. If the system pressure
falls to values below minimum, the boiler card will activate fault F37 (fig. 14).

fig. 14 - Low system pressure fault

Once the system pressure is restored, the boiler will activate the 120-second
air venting cycle indicated on the display by FH.

3. INSTALLATION
3.1 General Instructions

THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLI-
ANCE WITH ALL THE INSTRUCTIONS 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 - W 80 - W 125

is a heat generator arranged to operate alone or in

cascade (bank).
To install up to 4 generators

in bank

, appropriate accessories consisting of support

frames, water, gas and fume manifolds are available on request (consult the price-list or
contact the sales network )

FERROLI

The boiler's electronics can in any case manage a cascade

of up to 6 modules

. To cre-

ate systems in cascade with 5 or 6 modules it is necessary to have suitably sized water
/ gas manifolds complete with all the safety devices required by the current regulations
, as well as single fume exhausts or fume manifolds in low pressure (not supplied) in-
stalled by a qualified technician .
When two or more generators ENERGY TOP W 70 - W 80 - W 125 are installed in cas-
cade with the original kits FERROLI, respecting the instructions given in this manual,
they can be considered as a single equivalent heat generator with a total capacity equal
to the sum of powers of all the units connected cascade .
All the requirements of the current standards and regulations applicable to this "equiva-
lent" generator with total heating capacity must be met. In particular, the place of instal-
lation, 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 - W 80 - W 125 is a complete and independent heat
generator, equipped with its own safety devices. In case of overtemperature, lack of wa-
ter 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 single units and
connection in cascade.

3.2 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 conditions 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.

If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
vided for removing the casing and for normal maintenance operations

3.3 Plumbing connections

The heating capacity of the unit must be previously established by calculating the build-
ing's heat requirement according to the current regulations. The system must be provid-
ed with all the components for correct and regular operation. In particular, provide for all
the protection and safety devices required by the current regulations for the complete
modular generator. They must be installed on the hot water circuit delivery piping, imme-
diately after the last module, within a distance of not more than 0.5 metres, with no shut-
off devices in between. The unit is not supplied with an expansion tank, therefore its
connection must be carried out by the Installer.

The safety valve outlet must be connected to a funnel or collection pipe to pre-
vent 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 manu-
facturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.

Before installation, carefully clean all the system pipes to remove any residuals or impu-
rities that could affect proper operation of the unit.

Also, a filter must be installed on the system return piping to prevent impurities
or sludge from the system clogging 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 fail-
ure to install or inadequate installation of this filter.

Carry out the relevant connections according to the diagram in sec. 5.1 and the symbols
given on the unit.

System water charcteristics

In the presence of water harder than 25° Fr (1°F = 10ppm CaCO

), the use of suitably

treated water is advisable in order to avoid possible scaling in the boiler. The treatment
must not in any case reduce the hardness to values below 15°F (Decree 236/88 for uses
of water intended for human consumption). Water treatment is indispensable in the case
of very large systems or with frequent replenishing of water in the system. If partial or
total emptying of the system becomes necessary in these cases, it is advisable to refill it
with treated water.

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 components and/or materials of the boiler unit and sys-
tem. It is prohibited to use generic antifreeze fluid, additives or inhibitors that are not ex-
pressly suited for use in heating systems and compatible with the materials of the boiler
unit and system.

Optional kits

The following kits are available on request:

code 042021X0  - 3-SPEED Circulating Pump Kit
code 042047X0  - 3-SPEED HIGH HEAD Circulating Pump Kit
code 042043X0  - MODULATING Circulating Pump Kit

The Kits contain (see fig. 15):

CIRCULATING PUMP

(The diagrams of the circulating pumps are given in

sec. 5.5)

3-way COCK - Male 1"1/2 with non-return valve and safety valve

It enables shutoff (for maintenance operations) in conformity with

ISPESL re-

quirements

and can be used as a local shutoff in the connection of several

units in bank. The third way must be connected to an atmospheric discharge
manifold. Thus, with the valve in the "open" position, the boiler exchanger is
connected to the delivery manifold; and in the "closed" position, through the
third way, the exchanger communicates with the atmospheric discharge mani-
fold. This valve therefore also acts as a boiler discharge.

Heating temperature adjustment

Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.

DHW temperature adjustment
(with optional hot water tank
installed)

Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.

Summer/Winter Switchover

Summer mode has priority over a possible Remote Timer Control heating
demand.

Eco/Comfort selection

(with

optional hot water tank installed)

On disabling DHW from the Remote Timer Control menu, the boiler selects the
Economy mode. In this condition, the button detail 7 - fig. 1on the boiler panel is
disabled.
On enabling DHW from the Remote Timer Control menu, the boiler selects the
Comfort mode. In this condition it is possible select one of the two modes with
the button detail 7 -fig. 1.

Sliding Temperature

Both the Remote Timer Control and the boiler card manage Sliding Temperature
adjustment: of the two, the Sliding Temperature of the boiler card has priority.
