The Domina N 80 DGT is defined as a “room sealed” combination boiler, all air required for combustion is taken from outside the room in which it is installed. It is a new high performance gas fi red heat generator for central heating and domestic hot water production.
A special feature of this boiler is its built-in electronic flame ignition and control unit making burner operation completely automatic and safe. The main components are as follows: • Copper heat exchanger consisting of three finned tubes specifically shaped for high efficiency. • There are three copper coils inserted in the three heating circuit tubes. These represent the domestic hot water heat exchanger.
Their shape and high exchange surface area enable the full output of the boiler to be absorbed. • Ceramic fibre insulated combustion chamber • 12 stainless steel bladed burners specifically designed for this boiler. • Fan for discharge of combustion products and intake of combustion air. • Differential air pressure switch. For safety reasons, this ensures the burner ignites only when the fan is functioning correctly. • Hermetically sealed compartment made from corrosion-resistant steel enclosing the above components. • Combination gas safety valve with modulator, complete with pressure stabiliser. • Flowmeter giving the domestic hot water circuit precedence over the central heating circuit. • Pressure relief valve for the central heating circuit set to open at 3 bar. • Built-in Expansion vessel. • Variable speed pump. • Central heating flow temperature adjustment thermostat. • Domestic hot water flow temperature adjustment thermostat. • Central heating limit thermostat. • Overheat safety thermostat. • Electronic control unit for automatic flame ignition and control. • Central heating low water pressure cut off switch. • Domestic hot water flow temperature sensor.
