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 60/70/80/125 is a heat generator arranged to operate alone or in cas-
cade (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 60/70/80/125 are installed in cascade
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 60/70/80/125 is a complete and independent heat gener-
ator, equipped with its own safety devices. In case of overtemperature, 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 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-

3.3 Plumbing connections

Important

The heating capacity of the unit must be previously established by calculating the building's heat
requirement according to the current regulations. The system must be provided with all the com-
ponents for correct and regular operation. In particular, provide for all the protection and safety de-
vices required by the current regulations for the complete modular generator. They must be
installed on the hot water circuit delivery piping, immediately after the last module, within a distance
of not more than 0.5 m. and 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
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 dis-
charge 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, flush all the pipes of the system thoroughly to remove any residuals or impuri-
ties that could affect proper operation of the unit.
B
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 manu-
facturer declines any liability for damage caused to the generator by failure to install or
inadequate installation of this filter.
Carry out the relevant connections according to the diagram in sec. 5.1 and the symbols on the unit.
High-efficiency circulating pump (optional)
The factory setting is suitable for all installations; however a different operation strategy
can be set with the speed selector (see fig. 15), depending on the characteristics of the
system.

- Setting Dp-v Proportional head (fig. 16)
The circulating pump head will be automatically reduced with the decrease in flow rate
required by the system. This setting is optimum for systems with radiators (2 pipes or sin-
gle pipe) and/or thermostatic valves.
The strong points are the reduction in power consumption with the decrease in system
demand and reduction of noise in radiators and/or thermostatic valves. The operating
range is from min. (2) to max. (8).
- Setting Dp-v Constant head (fig. 17)
The circulating pump head will remain constant with the decrease in flow rate required
by the system. This setting is optimum for all floor systems or old systems with large
pipes.
In addition to reduced power consumption, in floor systems all the circuits will be bal-
anced for the same head loss. The operating range is from min. (1) to max. (8).
- Setting Fixed max. speed (fig. 18)
The circulating pump does not modulate its power, and will always run at max. speed.
The operating principle is that of conventional circulating pumps (with a reduction in pow-
er consumption compared to them).
