1DESCRIPTION
1.01 Introduction
The Domina102is definedas a“room sealed” combination boiler, all air requiredfor combustion is takenfrom
outside the room in which it is installed. It is anewhigh performance gas firedheat generator for central heating and
domestic hot waterproduction. Aspecial feature of this boileris its built-in electronic flame ignition and control unit
making burneroperation completely automatic and safe.The main components are as follows:
•Copperheat exchangerconsisting of three finnedtubesspecifically shapedfor high efficiency.
•There are three coppercoils insertedin the three heating circuit tubes. These represent the domestic hot waterheat
exchanger. Their shape and high exchange surface areaenable the full output of the boilerto be absorbed.
•Ceramic fibre insulatedcombustion chamber
•16 stainless steelbladedburners specifically designedfor this boiler.
•Fan for discharge of combustion products and intake of combustion air.
•Differential air pressure switch.For safety reasons, this ensuresthe burnerignitesonly whenthe fan
is functioning correctly.
•Hermetically sealedcompartment made from corrosion-resistant steelenclosing the above components.
•Combination gas safety valve with modulator, complete with pressure stabiliser.
•Flowmetergiving the domestic hot watercircuit precedence overthe central heating circuit.
•Pressure reliefvalve for the central heating circuit setto openat 3bar.
•Built-in Expansion vessel.
•Variable speedpump.
•Central heating flow temperature adjustment thermostat.
•Domestic hot waterflow temperature adjustment thermostat.
•Central heating limit thermostat.
•Overheat safety thermostat.
•Electronic control unit for automatic flame ignition and control.
•Central heating low waterpressure cut off switch.
•Domestic hot waterflow temperature sensor.
•Central heating flow temperature sensor.
•Safety bracket

N.B. - The gas pressures at the burner and gas flows during the central heating phase given in the table refer
to nominal boiler output.To reduce this output (where necessary), gas pressure must be reduced untilthe
required output levelis reached (see figures 4and 5).
During domestic hotwater production,gas pressures to the burner must correspondtothe maximum
outputgiven in table forthe type ofgas.
Gas pressure must beadjustedduring maximum draw-off ofdomestic hotwater.
•Maximum working temperature forcentral heating flow:85°C
•Maximum temperature ofdomestic hotwater:55°C, adjustable between 40°C and55°C.
•Minimum domestic coldwater pressure requiredfor95% heat input:
- Flowrestrictorfitted(standard)- 1,2 bar;
- Flowrestrictorremoved- 0,5 bar
