Available with “V” inverter execution TECHNICAL AND FUNCTIONAL CHARACTERISTICS • Low NOx and CO emissions gas burner compliant with European standard EN676 “Classe III”. • Two-stage progressive/modulating operation. • Ability to operate with output modulation by means of automatic RWF40 regulator mounted on the control panel (to be ordered separately with the modulation kit). • Gas adjustment by pneumatic air/gas ratio operation valve. • Partial combustion gas recirculation blastpipe with low NOx emissions (class III). • High ventilation efficiency, low electrical input, low noise. • Hinge opening on both sides for easy access to the combustion head when The burner consists of: • “V” execution: the fan electrical motor is controlled electronically by the motor speed controller. • Combustion air input with sound insulation and designed for optimal air damper opening linearity. • Light die-cast aluminium alloy electrical panel. • Printed circuit electrical connections. • Control panel with display diagram for working mode with indication lights, start/ stop switch, automatic/manual mode Electrical supply selector, minimum/maximum selector and burner unblocking button; possibility to install RWF 40 electronic modulator. • Electronic control box compliant with standard EN298, with running faults detection. • Ionizer electrode flame detection. • Gas train with safety valve and pneumatic air/gas ratio valve, minimum pressure switch, pressure regulator and gas filter. • Intelligent connectors for burner/train (error proof). The working field of the burner, as expressed in the “Thermal output kW” column, depends on the characteristics of the gas train it works with (see burner/train match diagram). Modulating mode Part.no 98000053 Kit RWF 40 - Modulation kit (see page 230). Accessories available on request 97980053 Soundproof burner cover (see page 247) Boiler coupling kit – 4 and 7 pin plug burner is installed. • Air capacity adjustment with linear opening controlled by electric servo motor. • Air damper closing when burner does not work. • Fan speed adjustment in relation to changes in burner demand provided by means of inverter, to obtain a significant reduction in noise levels and electricity consumption (version V only). • Electrical panel that connects by 4 and 7 pole plugs/sockets (standard accessories). • Electrical panel with protection rating of IP 55. • Sliding boiler coupling flange to adapt to head protrusion of the various types of boilers. • Gas train inlet can be mounted either upward or downward. CONSTRUCTION CHARACTERISTICS Two-stage progressive/modulating gas burners with low pollutant emissions Conform to: Gas Directive 90/396/CEE E.M.C. Directive 89/336/CEE L.V. Directive 73/23/CEE Reference standard: EN676 4) Equipped with air closure device. 11) The train must be always completed with the VPS kit to comply with the EN676 regulations. **) Maximum gas inlet pressure at pressure regulator in CE version, at gas train for EXP version. Net calorific value of natural gas: Hi = 35,80 MJ/m3 = 8550 kcal/m3, at reference conditions of 0°C, 1013 mbar.
