ARENA 30 C 2. INSTALLATION 2.1 General Instructions Gas Safety (Installation & Use) Regulations: 1996 In the interest of safety, it is the law that all gas appliances are installed by a competent person in accordance with the above Regulations, Building Regulations/Building Standards Scotland, Codes of Practice, current I.E.E.
ARENA 30 C for fastening it to the wall, using screws with metal wall plugs. The fastening to the wall must provide stable and effective support of the appliance. The boiler must be fastened to a closed part of wall, which is free of apertures or holes behind the frame of the boiler that may allow the internal components of the boiler to be reached.
ARENA 30 C In addition, shut-off valves should be installed between the boiler and the heating system to allow, if necessary, the boiler to be isolated from the system. If a non-return valve is also installed in the domestic hot water circuit, a safety valve must be fitted between the boiler and this circuit.
ARENA 30 C 2.5 Connection to the gas system If necessary the local Gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an adequate supply of gas. An existing service pipe must not be used without prior consultation with the Local Gas supplier.
ARENA 30 C 2.7 Electrical connections Power supply The boiler must be connected to a single-phase, 230 Volt-50 Hz power line, with max 3A fuses fitted between boiler and the line, as well as a bipolar switch ON/OFF with contacts whose opening is at least 3 mm. The boiler must always be properly earthed.
ARENA 30 C 2.9 Positioning the external probe The external probe is best installed on a wall facing north, north-west or which borders the majority of the main living area. The probe must never be exposed to the early morning sun, and, in general and where possible, must not receive direct sunlight;...
ARENA 30 C 2.10 Flues Arena is a type-C boiler with forced draught, the air inlet and the flue gas outlet must be connected to one of the exhaust–intake systems indicated as follows. Using the tables and the methods of calculation described, first verify, before installation, that the flues do not exceed the maximum allowed length.
Page 18
ARENA 30 C To locate the centre of the hole for the passage of the pipes in the wall, refer to Fig. 14: Fig. 14 Please consider that the horizontal concentric piping must have a slope towards the boiler of at least 3 mm/ m, to allow the condensation which forms in the flues to flow back to the boiler, and avoid external dripping.
ARENA 30 C 2.12 Connection to separate pipes The separate Ø60 pipes for air intake and flue gas exhaust can be connected directly to the boiler, as shown in Fig. 16a. Separate Ø80 pipes can be connected directly, once the two 80/60 (optional) reducers have been fitted inside the boiler (Fig.

ARENA 30 C For other accessories please refer to the manual: “Flue accessories and installation of forced air appliances” Example of how to calculate the connection of two separate pipes, max flue length: 100 metres The flue and air pipes must be sloped towards the boiler by at least 3%.
Gas conversion The adjustment and transformation operations must only be performed by Qualified Personnel. FERROLI S.p.A. declines all liability for damage to persons and/or things deriving from tampering with the appliance by non-authorised persons. The appliance can operate with natural or LPG supply gas, and is factory configured for use with one of the two gases, as is clearly marked on the packaging and on the rating plate on the appliance itself.

ARENA 30 C 4. OPERATING INSTRUCTIONS 4.1 Operation and controls The Arena 30C is a pre-mix condensing thermal generator for heating and the production of domestic hot water, using natural gas or LPG (configured at the moment of installation) and managed by an advanced microprocessor control system.
ARENA 30 C 4.3 Ignition Check than any shut-off valves in the heating system and domestic hot water circuit outside of the boiler are open. Open the gas cock upstream from boiler and press the main switch. The boiler will perform an self- test cycle lasting approximately one minute, at the end of which it is ready for operation.
ARENA 30 C 4.7 Setting the heating system temperature Set, using the room thermostat or remote control, the desired temperature inside the rooms. When acting on the room thermostat, the boiler is turned on and the heating system water is brought to the central heating outlet set temperature or calculated temperature (with temperature scrolling active).
ARENA 30 C 4.11 Outside temperature compensation When the (optional) external probe is installed, the boiler regulation system functions in “Outside temperature compensation” mode. In this mode, the temperature of the heating system is regulated according to the external climatic conditions, so as to guarantee a high degree of comfort and energy saving all year round.
