DOMINA F 24 30 E,FERELLA F 24 30 MEL,MILOS AIR COMPACT E. 1 TECHNICAL CHARACTERISTICS AND DATA,1 1 Introduction. Our appliance is a high efficiency heat generator for central heating and hot water production running. on natural gas or LPG configurable at the time of installation. The boiler shell consists of a copper laminar exchanger whose particular shape guarantees high exchange. efficiency under all operating conditions and an open flue burner equipped with electronic ignition and. ionization flame control, The boiler is totally sealed off from the installation room the air needed for combustion is drawn from. outside and the flue gases are expelled by a fan The boiler outfit moreover includes a variable speed. circulator expansion tank flow meter safety valve filler cock air pressure switch water pressure switch. temperature sensors and a safety thermostat, Thanks to the control and adjustment system unit operation is for the most part automatic The power. for heating is automatically governed by the control system according to the indoor characteristics the. characteristics of the building and of its location The power for hot water is automatically and continually. governed to ensure a fast delivery and comfort under all operating conditions. There are 5 LEDs on the control panel providing information on the unit s operating status. General Warnings, Installation and maintenance must be carried out by professionally qualified personnel.
according to current regulations and the manufacturer s instructions. Incorrect installation or poor maintenance can cause damage or physical injury The. manufacturer declines any responsibility for damage caused by errors in installation and use. or by failure to follow the manufacturer s instructions given in the instructions manual. Before carrying out any cleaning or maintenance operation disconnect the unit from the. electrical power supply using the switch and or the special cut off devices. Certification, The CE marking demonstrates that Ferroli gas units conform to the requirements contained in. the applicable European directives, In particular this unit complies with the following EU directives.

DOMINA F 24 30 E,FERELLA F 24 30 MEL,MILOS AIR COMPACT E. 2 PRODUCT FRAMEWORK AND INTERNAL,COMPONENTS,2 1 Hydraulic circuit heating. Hydraulic diagram for heating, When there is a call for heat the room thermostat or control system make the burners ignite and the. circulation pump come into operation The heat contained in the products of combustion is transferred. to the water by the system via the exchanger For more details on the operating logic refer to chap 3. 29 187 43 Key,5 Airtight chamber,16 7 Gas inlet,8 Tap water outlet. 9 Tap water inlet,10 System delivery,5 11 System return.

DOMINA F 24 30 E,FERELLA F 24 30 MEL,MILOS AIR COMPACT E. Circulator 230v 50Hz, Located on the heating circuit return it is connected directly to the exchanger. via special forks and connected to the system via a threaded brass section. It has three delivery head levels see diagram Changing the delivery head. changes the speed of the water flowing through the boiler exchanger and as. a result the temperature difference T between heating delivery and. return Clearly increasing the delivery of the circulator decreases T and vice. versa If it is not used for a long time the impeller might jam due to debris. in the water With the front screw it is possible to access the impeller which. can be freed with the aid of a screwdriver The connection to the expansion. tank and the air separator is installed on the pump casing. If the pump doesn t work, Check that the impeller is free to turn by turning the screw on the front.
with a screwdriver, Check that both the card and the pump connection are powered. If there is no power supply check the card,If there is power change the pump. 1 2 3 Pump selector position,A Losses of head 24kW version. B Losses of head 30kW version,Air separator, This is used to expel the air in the heating circuit automatically On boilers. with a twin heat exchanger it is located on the pump casing It is normally. accessible either via the fork or by simply unscrewing it from its seat. 12 Version 09 2002, Supplied By www heating spares co Tel 0161 620 6677.
DOMINA F 24 30 E,FERELLA F 24 30 MEL,MILOS AIR COMPACT E. Expansion tank, It is connected to the pump casing via a pipe with a fork connection On the 24kW version it is located. above the pump while on the 30kW version it is located behind the exchanger inside the frame The. expansion tank contains a diaphragm in contact on one side with the system water and on the other side. with the air under pressure pre loaded to 1 bar inside the tank By the expansion of the diaphragm and. ensuing compression of the air the tank compensates for the thermal expansion of the water in the. heating system,24kW 7 litre 30kW 10 litre,version version. Twin Heat Exchanger, The exchanger is a copper laminar assembly It comprises a thickly finned portion three circular pipes. containing the heating water and inside them another three pipes in the form of a spiral containing the. tap water The heating water exchanges directly with the burnt gases while the tap water does not have. this kind of exchange it receives heat indirectly from the water in the three heating pipes In this way the. surface of the coil does not reach very high temperatures so less scale gets formed In addition being very. small it makes the water speed very high over its entire section making mineral deposits of any kind. negligible The typical omega shape of the finning ensures an even distribution of the heat over all the. finning with consequent benefits in terms of exchange efficiency and the life of the exchanger A special. surface treatment protects the exchanger against oxidation and corrosion.

DOMINA F 24 30 E,FERELLA F 24 30 MEL,MILOS AIR COMPACT E. Hydraulic unit,This is a single piece of brass to which the. exchanger delivery is connected for ease of,access It accommodates a number of safety. and adjustment components,The hydraulic unit includes. safety valve,water pressure switch,heating sensor,filler cock.
tap water sensor,tap water check valve,Water pressure switch. It ensures a minimum pressure for the system It is normally open NO and. closes the contact when the pressure exceeds 0 5 bar It works on low. Safety valve, It opens if the pressure exceeds 3 bars making boiler operation safer and. protecting it against overpressure You are strongly recommended not to. use this valve to drain the system once open dirt could remain inside it. preventing it from closing completely,Check valve, This is necessary to ensure no water returns from the heating system to the. tap water circuit,Filler cock, This is located between the heating delivery and the tap water outlet It is not. fitted on the boiler for some markets such as the British and Belgian ones. 14 Version 09 2002, Supplied By www heating spares co Tel 0161 620 6677.
