Year 2000 Compliance Declaration
We will guarantee that this products is altogether suitable for the data change in the Year 2000 (boiler
has no dependence from date change) and that no disruptions will occur which is caused by this
product.
• Read the warnings given in this manual thorough-
ly. They provide important information for safe
installation, use and maintenance
• Keep the manual carefully for future consultation.
• The instruction manual is an integral and essential
part of the product and must be kept by the user.
• If the appliance is sold or transferred to another
owner or if the owner moves, leaving the appli-
ance behind, always ensure that the manual is
kept with the appliance for consultation by the
new owner and /or installer.
• Incorrect installation or poor maintenance ab-
solves the manufacturer from all liability for dam-
age to people or things.
• Installation and maintenance must be carried out
i conformity with current legislation, according to
the manufacturer’s instructions and by qualified
personnel.
• Before cleaning or maintenance, disconnect the
appliance from the mains via the switch on the
appliance or a suitable isolating device.

deactivate the appliance. Do not attempt to re-
pair or carry out any other operation on the
appliance directly. Contact qualified personnel
only.
• Repairs or the replacement of components must
be carried out exclusively by qualified personnel
using original spare parts only. Failure to respect
the above my compromise the safety of the appli-
ance.
• To guarantee efficient operation, the appliance
must be serviced once a year by an authorised
service centre.
• The appliance may not be used for purposes
other than those for which it was explicitly de-
signed. Any other use is considered improper and
therefore dangerous.
• Incorrect installation and use or failure to follow
the instructions provided by the manufacturer
absolve the manufacturer from all liability for
damage.
• After unpacking, check that the contents are
whole and undamaged.
• Keep packing out of reach of children as it is
potentially hazardous.
• To clean external parts, use a damp cloth mois-
tened with soapy water if necessary. Avoid using
abrasive cleaning products and solvents.

1.1 Introduction
Dear Customer,
Thank you for having chosen the Arena 30 C, the latest generation FERROLI wall-hung boiler, featuring
advanced design and cutting-edge technology.
The Arena 30 C is a pre-mix condensing thermal generator for heating and the production of domestic hot
water, with very high thermal efficiency and very low emissions, fired by natural gas or LPG.
The boiler body is made up of a prismatic mono-block heat exchanger, with a hexagonal base made from
aluminium alloy, inserted in a cylindrical steel jacket, with water cavity, and insulated externally with high-
density foam. The special design of the heat exchanger allows effective condensation of the water vapour
contained in the flue gases, making the Arena highly efficient. The heat exchanger has been designed to
maintain its characteristics of high thermal exchange over time.
Inside the aluminium mono-block heat exchanger, in a cooled combustion chamber, lies the pre-mix burner
assembly,witharadialshapeand metallic surfaces, featuring electronic ignition withionisationflamecontrol,
which allows extremely low emission values, and at the same time guarantees high reliability and constant
operation over time.
The combustion circuit and the air intake are sealed from the installation environment.
The boiler is fitted with a variable speed fan and built-in modulating gas valve, connected directly to the
outside.
The boiler control and regulation system is microprocessor-based, with advanced self-diagnostics. The user
interface, made up of a keypad and display, is user-friendly, and shows the operating status of the appliance
at all times. The operating parameters and the data logs are saved internally and can be called up using the
Personal Computer interface to simplify Service operations.
The heat output is regulated continuously across the entire operating range, with temperature-scrolling
climate control, which automatically adapts the operating mode to the characteristics of the internal and
external environments, of the building and its location.
Aspecialinternaldeviceallowsultra-fastproductionofdomestichotwater:hotwaterisavailableattheboiler
outlet as soon as the hot water tap is opened.
Completing the fitted devices are a variable-speed heating pump and a fixed-speed domestic hot water
pump, a high-capacity expansion vessel, flowmeter, safety valve, drain cock, water pressure switch, flue gas
sensor, temperature sensors and safety thermostat.
