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.

ENERGY TOP B is a heat generator arranged to operate alone or in cascade (bank).
When two or more generators are installed in cascade with the original kits ENERGY
TOP B, respecting the prescriptionsFERROLIof 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" total heating capacity generator 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 B is a complete and independent heat generator, equipped
with its own safety devices. In case of overtemperature, no water or no circulation in the
unit , the protection devices cause the unit to shutdown , preventing its operation.

The installation instructions given in the following paragraphs concern single units and
connection in cascade.

Given below are the possible configurations for connection in cascade.

3.2 Place of installation

The generator can be installed directly outside or in a suitable room with ventilation open­ings to the outside as prescribed by the current regulations. If there are several burners
or extraction units 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 objects or materials, corrosive gases, volatile substances or dusts.
For positioning, leave enough space around the modules for normal maintenance oper­ations. Make sure the front door opens without hindrance.

B

The air necessary for combustion enters through special openings in the bot­tom and top part of the unit. Make sure these air passages are not obstructed
in any way.

fig. 18 - Air inlet

3.3 Gas and water connections

Plumbing connections

Make the relevant connections according to the instructions given below. Make the gen­erator connection in such a way that its internal pipes are free of stress. For proper op­eration and long life of the generator, the plumbing system must be of suitable size and
complete with all the accessories that guarantee regular operation and running.

In particular, provide for all the protection and safety devices prescribed by current reg­ulations for the complete modular generator. 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 shut-off devices in between. A "Safety Device and Circuit Breaker module”
equipped with internal hydraulic circuit breaker and safety units with ISPESL certification
is available by request. Refer to the price-list or contact our sales network. The unit is not
supplied with an expansion tank; its connection must therefore be made by the Installer.

B

A filter must also be installed on the system return piping to prevent impurities
or sludge from the system clogging and damaging the heat generators.

The filter must necessarily 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.

Water system characteristics

In the presence of water harder than 25° Fr, it is advisable to use suitably treated water,
in order to avoid possible scaling in the boiler caused by hard water, or corrosion pro­duced by aggressive water. Due to its low thermal conductivity, scaling even just a few
mm thick causes significant overheating of the generator walls, with consequent serious
problems.

Water treatment is indispensable in case of very large systems (containing large
amounts of water) or with frequent introduction of replenishing water in the system. If par­tial or total emptying of the system becomes necessary in these cases, it is advisable to
refill with treated water.

Gas connection

The gas must be connected to the corresponding union with a rigid metal pipe.
The gas meter must be adequate for the simultaneous use of all units connected to it.

Carry out the generator gas connection in accordance with current regulations. The di­ameter of the gas pipe leaving the generator does not determine the diameter of the pipe
between the unit and the meter; it must be chosen according to its length and pressure
loss.

B

Make sure to install a fuel shutoff valve externally with respect to the modules,
enabling the gas to be turned off even without opening the single modules
equipped with key closing.

Connection instructions
ENERGY TOP B is equipped on the inside with 3 manifolds (gas, system delivery and

return) and a condensate drain pipe that facilitate cascade connection and also connec­tion of a single module to the system. The manifolds are sized for a connection in series
of up to 1000 kW.

The cabinet contains a set of 3 seals (2 for water manifolds, 1 for gas manifold) with re­spective bolts and nuts, to be used for connection to a subsequent module (connection
in cascade). The optional kit code 042027X0, containing 3 blind flanges and 3 drilled
flanges with respective seals and screws, is available on request for the connection to
the system.

Safety device and separator module (optional)

The Safety Device and Separator Module for series ENERGY TOP Bmodular gener­ators is an ISPESL certified module containing a hydraulic separator and safety, protec­tion and control devices required by file "R" section R3A and R3B, intended for use with
series ENERGY TOP Bmodular generators .

Every ISPESL Safety Device Module comprises a cabinet of the same size and appear­ance as the modular generators ENERGY TOP B, containing a hydraulic separator with
air valve and thermal insulation, the respective system delivery and return manifolds, a
gas manifold, and a discharge manifold for the safety valve. The safety devices required
by file "R" section R3A and R3B are fitted on the hydraulic manifolds and hydraulic sep­arator body. Provision is also made for the probe pocket of a possible fuel shutoff valve,
to be installed in the system , on the outside of the bank of modules.

The hydraulic separator contained in the module allows the hydraulic circuit of the mod-
ules ENERGY TOP B (primary circuit) to be made independent of the hydraulic circuit of
the respective heating system (secondary circuit). The separator is sized for correct op­eration up to 1000 kW, and the main advantages offered are:

• An external circulating pump for the primary circuit is not necessary. In fact, circula­tion in the primary circuit is ensured by the circulating pumps contained inside the
generators ENERGY TOP B.

• When the secondary pump is deactivated, also the circulation in the system circuit
stops; the entire flow delivered by the circulating pumps contained inside the gener­ators ENERGY TOP B is bypassed through the hydraulic separator.

• The flow in the primary circuit can remain constant, whereas the secondary circuit
can function with a variable or intermittent flow rate.

• There are no anomalous operating conditions in which the system pumps interact
with the circulating pumps in side the generators ENERGY TOP B, creating unwant-
ed head and flow-rate variations in the circuits.

• Sizing of the system circulating pump can be carried out according to the needs of
just the secondary circuit.

3.4 Electrical connections

Connection to the electrical grid

B

The unit's electrical safety is only guaranteed when correctly connected to an
efficient earthing system executed according to current safety standards. Have
the efficiency and suitability of the earthing system checked by professionally
qualified personnel. The manufacturer is not responsible for any damage
caused by failure to earth the system. Also make sure that the electrical system
is adequate for the maximum power absorbed by the unit, as specified on the
boiler dataplate.

The boiler is prewired and provided with a Y-cable and plug for connection to the elec­tricity line. The connections to the grid must be made with a permanent connection and
equipped with a bipolar switch whose contacts have a minimum opening of at least 3
mm, interposing fuses of max. 3A between the boiler and the line. It is important to re­spect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green
wire) in making connections to the electrical line. During installation or when changing
the power cable, the earth wire must be left 2 cm longer than the others.

B

The user must never change the unit's power cable. If the cable gets damaged,
switch off the unit and have it changed solely by professionally qualified person­nel. If changing the electric power cable, use solely “HAR H05 VV-F” 3x0.75
mm2 cable with a maximum outside diameter of 8 mm.

Room thermostat (optional)

B

CAUTION: The room thermostat must have clean contacts. CONNECTING
230 V. TO THE TERMINALS OF THE ROOM THERMOSTAT WILL IRREPA­RABLY DAMAGE THE ELECTRONIC CARD.

When connecting a remote timer control or a timer switch, do not take the pow­er supply for these devices from their cut-out contacts. Their power supply must
be taken with a direct connection from the mains or with batteries, depending
on the kind of device.

External probe (optional)

Connect the probe to the respective terminals. The maximum permissible length of the
electric cable connecting the boiler - external probe is 50 m. A common 2-wire cable can
be used. The external probe should preferably be installed on the North, North-West wall
or on the wall facing most of the main living-room. The probe must never be exposed to
the early morning sun, and in general (as far as possible) it should not be exposed to
direct sunlight; protect it if necessary. In any case, the probe must not be installed near
windows, doors, vents, flues or heat sources that could affect the reading.

• Module 4: arrow symbol at top right of the display

If this does not occur, disconnect the power and check the wiring in fig. 32.

Settings

All adjustments must be made on all the modules.

Possible faults

If the electrical connection of a module is disconnected for any reason, module 1 will ac­tivate fault F70.

If the electrical connection of a module is disconnected for any reason, the next module
will activate fault F71.

3.5 Flue connection

Important

The unit is a B23 type with combustion air drawn from the installation room and fume ex­haust by means of a fan (operation with flue under pressure) and must be connected to
one of the discharge systems indicated below. Before proceeding with installation, check
and carefully comply with the local regulations and provisions. Also comply with the pro­visions concerning the positioning of wall and/or roof terminals and the minimum distanc­es from windows, walls, ventilation openings, etc.

Manifold, ducts and flue must be suitably sized, designed and made in compliance with
the current standards. They must be made of suitable materials, i.e. resistant to heat and
corrosion, smooth on the inside and hermetic. In particular, joints must be condensate­proof. Also provide for suitable condensate drainage points, connected through a trap to
prevent the condensate produced in the flues from running into the generators.

B

The unit is equipped with one (models ENERGY TOP B 80 - 125) or two (mod­els ENERGY TOP B 160 - 250) separate Ø80 flue connections for the two burn-
er - exchanger units.

The combustion circuits of the two units are completely independent. When
joining the two fume outlets to a single flue or manifold (in case of a single mod­ule or connection in cascade) it is necessary to install a fume anti-backflow val­veon each outlet to prevent operation anomalies or the creation of hazardous
conditions. Make sure to use the optional FERROLIkits , provided with special
anti-backflow valves.

A

Before carrying out the flue connection, make sure to fill the condensate trap
with approx. 0.5 litres of water through the flue connections.

Connection with separate pipes

Separate Ø80 ducts can be connected directly to the unit Insert the seal 1KWMA84A on
the Ø80 pipes leaving the unit and make it adhere to the upper wall of the cabinet

Before installation, make sure the maximum permissible length has not been exceeded,
by means of a simple calculation:

1. Establish the layout of the system of split flues, including accessories and outlet ter­minals for each of the two burner/exchanger bodies

2. Consult the table 5 and identify the losses in meq (equivalent metres) of every com­ponent, according to the installation position

3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 4.

Before installing the flues, fill the trap with approx. 0.5 l. of water through the
flue connections.

B

For outside installations make the seal 1 adhere perfectly to the top part of the
cabinet, to prevent possible infiltration of rain and atmospheric agents.

Connection with manifolds

To connect one or more modules in bank to a single flue, it is advisable to use the special
manifolds (optionals) given in the table. The choice of diameter must be made according
to the total power of the bank of units, respecting that given in the table. Use a starting
kit for each bank (containing manifold plug and trap) and a suitable number of manifolds
(one for each ENERGY TOP B 80 - 125 and two for each ENERGY TOP B 160 - 250).

90° bends and manifold extensions are also available for the flue connection.

ing power will appear alongside.

fig. 55 - TEST mode (heating power = 100%)

To deactivate Test mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.

Only for model ENERGY TOP B 160 - 250

In TEST mode, press the button (detail 7 - fig. 1) to obtain the following operation:

• Top boiler shell on; bottom boiler shell off.

• Top boiler shell off; bottom boiler shell on.

• Top boiler shell on; bottom boiler shell on.

Heating Capacity Adjustment (RANGE RATED)

A

This is a “RANGE RATED” boiler (according to EN 483) and can be adjusted
to the system's thermal requirement by setting the maximum heating capacity
for operation in heating mode, as follows:

• Put the boiler in TEST mode (see sec. 4.1).

• Press the

heating buttons

(details 3 and 4 -

fig. 1

) to increase or decrease the power (min.

= 00 - max. = 100). See the diagram “Heating Capacity Adjustment” (

fig. 56

).

• Press the reset button (detail 8 - fig. 1) within 5 seconds and the maximum heating
capacity will remain that just set. Exit TEST mode (see sec. 4.1).

4.2 Start-up

B

Checks to be made at first lighting, and after all maintenance operations that
involved disconnection from the systems or an operation on safety devices or
parts of the boiler:

Before lighting the boiler

• Open any on-off valves between the boiler and the systems.

• Check the tightness of the gas system, proceeding with caution and using a soap
and water solution to detect any leaks in connections.

• Check correct prefilling of the expansion tank (ref. sec. 5.4).

• Fill the water system and make sure all air contained in the boiler and the system
has been vented, by opening the air vent valve on the boiler and any vent valves on
the system.

• Fill the condensate trap and check correct connection of the condensate elimination
system.

• Make sure there are no water leaks in the system, DHW circuits, connections or boiler.

• Check correct connection of the electrical system and efficiency of the earthing system

• Make sure the gas pressure value for heating is that required.

• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler

Checks during operation

• Turn the unit on as described in sec. 2.3.

• Make sure the fuel circuit and water systems are tight.

• Check the efficiency of the flue and air-fume ducts while the boiler is working.

• Check the correct tightness and functionality of the condensate elimination system
and trap.

• Make sure the water is circulating properly between the boiler and the systems.

• Make sure the gas valve modulates correctly in the heating and domestic hot water
production phases.

• Check proper boiler lighting by doing several tests, turning it on and off with the room
thermostat or remote control.

• Using a combustion analyser connected to the boiler fume outlet, check that the
CO

2

content in the fumes, with the boiler operating at max. and min. output, corre-

sponds to that given in the technical data table for the corresponding type of gas.

• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on sec. 5.4.

• Check the correct programming of the parameters and carry out any necessary cus­tomization (compensation curve, power, temperatures, etc.).

4.3 Maintenance

Periodical check

To keep the unit working properly over time, it is necessary to have qualified personnel
make an annual check that includes the following tests:

• The control and safety devices (gas valve, flow meter, thermostats, etc.) must func­tion correctly.

• The fume extraction circuit must be fully efficient.

• The airtight chamber must be sealed

• The air-fume end piece and ducts must be free of obstructions and leaks

• The condensate evacuation system must be efficient with no leakage or obstructions.

• The burner and exchanger must be clean and free of scale. When cleaning, do not
use chemical products or wire brushes.

• The electrode must be free of scale and properly positioned.

• The gas and water systems must be airtight.

• The water pressure in the cold water system must be about 1 bar; otherwise, bring
it to that value.

• The circulation pump must not be blocked.

• The expansion tank must be filled.

• The gas flow and pressure must correspond to that given in the respective tables.

A

The boiler casing, panel and aesthetic parts can be cleaned with a soft damp
cloth, possibly soaked in soapy water. Do not use any abrasive detergents and
solvents.

4.4 Troubleshooting

Diagnostics

The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault, the
display will flash together with the fault symbol (detail 20 -

fig. 1

) indicating the fault code.

There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the RESET button (detail 8 - fig. 1) for 1 second or RESET on the
optional remote timer control if installed; if the boiler fails to start, it is necessary to firstly
eliminate the fault.

Other faults (marked with the letter “F”) cause temporary shutdowns that are automati­cally reset as soon as the value returns within the boiler's normal working range, except
for fault F37 which is reset by turning the unit off and then on again with button 14 of
fig. 1.
