1 ENERGY TOP Condensing boiler solutions 1

2 ENERGY TOP > ENERGY TOP RANGE A wide array of flexible solutions both for centralised residential application and big commercial plants The increasing need for families to be able to manage their central heating system freely and independently led to the expansion of independent systems, gaining ground over the traditional centralised approach to heating. Independent systems have been and continue to be preferred by users, mainly due to: - independent management - costs exactly corresponding to own consumption; - less possibility of controversies between residents. Nonetheless, centralised systems, albeit less appreciated by users, have been recently reappraised thanks to some undeniable qualities : less overall capacity installed; less environmental impact due to the use of just one flue or stack, and separate installation of the generator in a boiler room. The development of centralised systems with independent billing, using so-called submeter, combine all the advantages of independent and centralised systems mentioned above. For this reason, the new series of ENERGY TOP modular heat generators together with submeter DADO (not described in this catalogue) represent a modern and complete solution to the latest needs, which require a balance between centralised production of heat and independent and individual management of consumption. Both in the residential and the commercial field, wide output modulation range of Energy Top, additionally enhanced in modular installation, together with its low hydraulic pressure drop, allows design and carrying out of flexible systems with extremely compact dimensions, fully in line with the latest heating technology design criteria.

3 ENERGY TOP > THE HEART HEATING UNIT The HEART of ENERGY TOP is an innovative heating unit that ensures the product excellent characteristics in terms of efficiency and flexible modulation. The new total premixed air-gas combustion unit with variable speed fan, pneumatic gas valve and cylindrical metal fibre burner allows a range of modulation that, depending on the model, can extend from 11 to 100% of rated output, with efficiency exceeding 107%. Heat exchange takes place in the spiral corrugated pipe exchanger, which features low pressure drop. Despite the high heat exchange surface, it is particularly sturdy and compact. The quality of the materials used ensures the exchanger a high level of resistance to corrosion and thermal dilations, supporting a max ΔT of 40 C. The very low polluting emissions - NOx and CO - as well as minimising the environmental impact of these heat generators (class 5 according to EN 297/A5), also let the heat exchanger remaining clean over time, reducing to the minimum maintenance intervention. Ignition is electronic, with flame control by ionisation. The heating units have been designed with two different heat input ratings: 75 and 116 kw, and based on the total output, the various models of ENERGY TOP can house one or two units of 75 or 116 kw each, always inside a unique cabinet structure. The models with two heating units are also managed by the same electronic controller. 100% 50% 30% 22% 11% ENERGY TOP 80 > MODULATION RANGE ENERGY TOP 125 ENERGY TOP 160 ENERGY TOP 250 PREMIX BURNER Premixed air-gas, metal fibre burner, with variable speed fan.

The MASTER/SLAVE function allows operation of a series of cascaded boilers, without requiring an additional control unit. With just a simple connection (two wires) between the control boards of the boilers in the cascade, the entire system acts as a single virtual boiler. The safety circuit reduces boiler lockout and system shutdown, automatically attempting to ignite the module three times in the event of temporary shutdown (natural gas versions). If the shutdown occurs repeatedly, the system goes into permanent lockout mode, for safety reasons. Control board features a series of input and output signals, both analogue and digital (on/off), in order to control or adjust the operation of the single boiler or the entire cascade system also via a remote connection. Below are some examples: FAULT SIGNAL Active in case of boiler s fault message BURNER ON SIGNAL Active when at least one heating unit is on RESET SIGNAL Used to reset temporary faults Combined management of the signals allows the operating status of the heat generator to be checked and set via a remote connection C/%P 10 Volt 0-10 VOLT INPUT SIGNAL Allows the boiler (or cascade of boilers) to be controlled via a remote connection, in system outlet temperature or output percentage mode.

6 ENERGY TOP W RANGE TECHNICAL DRAWINGS The ENERGY TOP W series boilers are wall-hung heat generators for inside or outside installation, central heating only, featuring a premix burner, condensing operation with very high efficiency and very low polluting emissions. They consequently ensure high energy savings and are environmentally-friendly (4 star energy rating according to Directive 92/42 EEC, Class 5 emissions according to EN 297/A5). Wall-hung structure with removable jacket split in 3 sections, for easy access to the inner components. Possible installation as standard outdoor in partially protected places, with temperatures untill to -5 C, without using the additional frost protection kit. The cascaded connection of multiple generators can be carried out using dedicated cascade flues and hydraulic collective manifold. The appliances are factory configured for operation on natural gas and can be converted to LPG using the appropriate conversion kit available upon demand. > THE RANGE ENERGY TOP W 80 Wall hung model with single heating unit and thermal input from 17 to 75 kw ENERGY TOP W 125 Wall hung model with double heating unit and total thermal input from 25 to 116 kw KEY 1 CH flow 1 1/2 F 3 Gas inlet1 M 5 Ch return 1 1/2 F ENERGY TOP W A mm

The frames enable very easy installation of flues and water manifold and steady support.

11 ENERGY TOP W SETTING AND CONTROL The ENERGY TOP W series boilers boast an evolved electronics that can manage as standard up to two direct heating zones or an eventual storage cylinder with one direct zone, without requiring additional electronic controllers. PS: Diagrams are for mere example only and need to be verified according to the specific installation. > MIXED CIRCUIT WITH PRIORITY TO THE STORAGE TANK Legionella disinfection signal Recirculation timer Each boiler or cascade of boilers can be connected to an outdoor temperature probe for flow temperature compensation operation. MASTER-SLAVE interconnection between the boilers permits multiple cascade configurations without requiring additional control boards. > MIXED CIRCUIT WITH PRIORITY OR SIMULTANEOUS OPERATION OF THE STORAGE TANK Legionella disinfection signal Recirculation timer The Legionella protection function, after a programmable time interval, ensures the temperature inside the storage cylinder remains at 65 C for 15 minutes. When Legionella protection is active, the boiler s electronics sends an output signal (voltage-free contact) that can be used to control a recirculating pump. This ensures the entire water content in the circuit is protected. In the case of combined systems (without diverting valve) domestic hot water storage cylinder can be heated simultaneously with the central heating or as a priority function depending on the characteristics of the system. 11

In this case too, the operation of the domestic hot water circuit can be managed with priority or together with the central heating circuits. 12
