4. TECHNICAL AND CONSTRUCTIONAL
SPECIFICATIONS, DIMENSIONS
4.1 Description of the appliance
The construction of the series boilers
guarantees high output and efficiency at low flue
gas temperatures, thus ensuring reduced pollu-
ting emissions.
The appliances are made according to the EN
303 standard, part 1.
The main technical elements of the design are:
- the careful design of the shapes, to ensure an
optimum ratio between the combustion volu-
mes and the heat exchange surfaces
- the choice of materials used, for the long life of
the boiler.
The boilers feature pressurised combustion,
with three flue passes, a horizontal-cylinder con-
figuration and flame reversal in the furnace,
completely cooled; the flame produced by the
burner is reversed peripherally towards the
front, where the flue gas enters the tube bundle,
featuring turbulators to create a swirling path
that increases the heat exchange by convection.
On leaving the tube bundle, the flue gas enters
the rear chamber and is transferred to the chim-
ney. The boilers are fitted with a door featuring
hinges that can be reversed for opening to the
right or the left, and is adjustable in both height
and depth. The body plating is insulated with a
thick layer of glass wool, and covered with a
further layer of tearproof material. The external
finish consists of painted steel panels. The hoi-
sting hooks are fitted on the top of the plating.
The boilers feature two 1/2” fittings for bulb
sheaths (able to house three bulbs each).
The pre-wired control panel is located above the
boiler, and allows automatic operation.
4.2 Operating principle
The boilers are fitted with a closed
cylindrical furnace, in which the flame produced
by the burner is reversed peripherally towards the
front, from where the burned gas enters the fire
tubes. At the outlet, the gas is collected in the
smokebox and is then sent to the chimney. The
combustion chamber is always pressurised
during the operation of the burner.
For the pressure values, see the tables on page
16, under the column Flue gas side pressure drop.
The flue and the flue stack fitting must be made
in compliance with the standards and the legisla-
tion in force, using rigid pipes that are resistant to
high temperatures, condensate and mechanical
stress, and are airtight. (Fig. 1)

4.4 Identification
The boiler can be identified from the:
-
Document envelope
This is applied to the door, and contains:
TECHNICAL MANUAL
WARRANTY CERTIFICATE
LABELS WITH BARCODE
RATING LABEL
CONSTRUCTION CERTIFICATE
(certifying that the water pressure tests have
been passed)
- Rating label
This describes the technical specifications
and the performance of the appliance (Fig. 4).
It is included in the document envelope and
MUST BE APPLIED by the installer, when
installation is complete, to the top front part of
one of the side panels of the casing, in a visi-
ble position.
If the label is lost, contact the Ferroli
Technical Service for a duplicate.
Tampering with or the removal or absence of
rating labels or other means enabling the unit to
be identified causes problems during installation
and maintenance.

N
boiler.
This manual has been prepared to provide you
with information, warnings and suggestions on
the installation, correct use and maintenance of
the boiler. Please therefore read it thoroughly
and keep it with care for future reference.
In your interest, we suggest that you carefully
observe the contents of this manual, so as to
be able to get the most from this high quality
product. The Manufacturer declines all liability and the
warranty will be void in the event where the

2. GENERAL WARNINGS
- This instruction manual is an integral part of
the product, and provides important instruc-
tions for installation, operation and maintenance.
- This appliance must only be used for the pur-
poses it has been specifically designed for.
- This appliance is used to heat water to
below-boiling temperatures at atmospheric
pressure, and must be connected to a cen-
tral heating and/or domestic hot water
distribution system, according to its cha-
racteristics, performance and heat output.
- Before installation, check that the boiler has
not been damaged due to handling and
transport.
- The boiler must be installed in compliance
with the standards in force, by suitably quali-
fied personnel.
- Before performing any cleaning or maintenan-
ce operations, disconnect the appliance from
the mains power supply.
-
Lamborghini
S.p.A.
is not liable for any damage to
per
sons people and/or things due to errors in
installation, control, maintenance and
improper use.
- The boiler and the corresponding system must
be commissioned by authorised personnel.
- Commissioning is performed in order to check
the correct operation of all the control devices.
- Qualified personnel must be contacted if the
appliance is not used for an extended period.
Standards
The installer must observe the local standards
in force as regards: the choice of the site of
installation of the boiler, the compliance with the
required ventilation conditions; the tightness of
the connection to the chimney; the connections
of the fuel lines, electrical systems and any
other relevant safety standards.
Warranty conditions
The warranty is only valid if the standards and
the suggestions for use described in this manual
are observed. Failure to observe such stan-
dards and suggestions will void the warranty.
The warranty excludes all damage due to cor-
rosion from the acidic condensate of the pro-
ducts of combustion or the formation of depo-
sits caused by the use of hard or aggressive
water, as such are solely due to the operation
of the system.
