ARENA 30 A

1. CHARACTERISTICS AND TECHNICAL DATA

1.1 Introduction

Dear Customer,
Thank you for having chosen the Arena 30 A, the latest generation FERROLI wall-hung boiler, featuring
advanced design and cutting-edge technology.
The Arena 30 A 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, with a radial shape and metallic surfaces, featuring electronic ignition with ionisation flame control,
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 is preset for connection with external DHW storage. An internal circulator for DHW, connection
dedicated to DHW storage, DHW probe make the connection extremely simple.
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 (also with DHW storage), 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.
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.
