3. INSTALLATION
3.1 General Instructions
THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLIANCE 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.
QUADRIFOGLIO B is a heat generator arranged to operate alone or in cascade (bank).
FERROLI S.p.A. supplies (on request) all the plumbing fittings and fume manifolds for
the connection of 2 or 3 units in cascade in configurations of 70 + 70 kW to 320 + 320
+320 kW.
When the generators QUADRIFOGLIO B are installed in cascade with the accessories
provided for by FERROLI, they can be considered as a single heat generator with equivalent total capacity equal to the sum of the powers of all the units connected in cascade.
All requirements of the current rules and regulations applicable to this generator of
"equivalent" 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. The requirements given in this manual apply to the single unit as well
as connection in cascade. For further information regarding the installation of generators
in cascade, refer to the manual supplied with the cascade connection kits.
A
The boiler electronics have a function for a managing a cascade of up to 6 units.
To create cascade systems with more than three units without using the accessories provided for by FERROLI, it is necessary to arrange hydraulic/gas manifolds of appropriate size and complete with all the safety devices required by
the current regulations, as well as single fume exhausts or manifolds appropriately sized by a qualified technician.
3.2 Place of installation
The generator must be installed in an appropriate room with ventilation openings towards
the outside in conformity with the current regulations. If there are several burners or exhausters 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 materials or objects, corrosive gases, powders or volatile substances. The
room must be dry and not exposed to rain, snow or frost. For positioning, leave sufficient
room around the unit for normal maintenance operations. In particular, check that the
burner door can open freely.
3.3 Plumbing connections
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 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, immediately after the last module, within a distance not more than 0.5 metres, with no shut-off
devices in between. The unit is not supplied with an expansion tank or safety valve,
their 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 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.
B
Before installation, carefully wash all the pipes of the system to remove
any residuals or impurities that could affect proper operation of the unit.
Use chemical conditioners that are suitable for the purpose, i.e. able to remove
from the walls and bottom of the pipes and the various components of the system, sludge, metal oxides and, in low temperature systems, also biomass, with
just the circulation of the water, with system hot and/or cold. The products used
must not be corrosive and/or aggressive for metals and plastics and must not
significantly alter the natural pH of the water.
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
manufacturer 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. 5.1and the symbols
given on the unit.

If only one system return is used, connect to the main return connection C.
If two system returns are used, connect the low temperature return (e.g. floor system) to
connection C and the high temperature return to connection B (e.g. hot water storage
tank or radiators). Also, the system return probe must be moved from the pocket in
return pipe C to the pocket in return pipe B. Once the probe is repositioned, make
sure to secure it with the special clip (see fig. 32).
In case of installation in bank, the water circuit of each boiler must be fitted with a motoroperated shutoff valve (controlled by the unit, see wiring diagram fig. 87) that prevents
reverse circulation with the boiler not working.
A single safety valve must also be provided for each boiler in accordance with the requirements of “file R”.
The following optional kits are available for this purpose:
052000X0 - MOTOR-OPERATED BUTTERFLY VALVE DN50
052001X0 - MOTOR-OPERATED BUTTERFLY VALVE DN65
If the adjustment of the distribution system is independent from the electronics of
the generators, the creation of a bypass between the delivery manifold and that of
the system return is advisable in order to protect the circulating pumps.
Characteristics of the water system
The boilers QUADRIFOGLIO B are suitable for installation in heating systems with non-
significant entry of oxygen (ref. systems "case I" Standard EN14868). A separator
must be provided in systems with continuous entry of oxygen (e.g. underfloor systems
without antidiffusion pipes), or intermittent (e.g. in case of frequent replenishments).
The water inside a heating system must have the characteristics indicated by Standard
UNI 8065, and the provisions of Standard EN 14688 (protection of metallic materials
against corrosion) must be complied with.
The filling water (first filling and subsequent replenishment) must be clear, with hardness
below 15°F and treated with suitable chemical conditioners against the initiation of corrosion, that are not aggressive on metals and plastics, do not develop gases and, in lowtemperature systems, do not cause proliferation of bacterial or microbial masses. In case
of hardness above 15 °F suitable softening treatment and/or the use of suitable anti-fouling agents must be provided for.
The water contained in the system must be periodically checked (at least twice a year
during the season when the systems are used, as required by UNI8065) and have: possibly a clear appearance, a pH above 7 and below 8.5, an iron content (Fe) below 0.5
mg/l, a copper content (Cu) below 0.1 mg/l, a chloride content below 50mg/l, and must
contain chemical conditioners in a concentration sufficient to protect the system for at
least one year. Bacterial or microbial loads must not be present in systems at low temperature.
B
Conditioners, additives, inhibitors and antifreeze liquids can be used only and
exclusively if the producer guarantees their suitability for use in heating systems and that they do not cause damage to the boiler's heat exchanger or other
components and/or materials of the boiler and system. The use of generic
chemicals not specific for use in heating systems and/or incompatible with the
materials of the boiler and system is forbidden. Chemical conditioners must ensure complete deoxygenation of the water, must contain specific protection for
yellow metals (copper and its alloys), anti-fouling agents for scale at least up to
15°F, neutral pH stabilizers and, in low-temperature systems, specific biocides
for use in heating systems.
B
The unit is equipped with an antifreeze system that activates the boiler in heating mode when the system delivery water temperature drops below 6 °C. The
device is not active if the power and/or gas supply to the unit is turned off.
If necessary, for system protection use a suitable antifreeze liquid that meets
the same requirements as set out above and provided for by Standard UNI
8065.
B
Regarding domestic hot water, no type of treatment that can prevent its possible food use can be provided for.
