INFORMATION ABOUT THE INSTRUCTION MANUAL INTRODUCTION The instruction manual supplied with the burner: is an integral and essential part of the product and must not be sepa- rated from it; it must therefore be kept carefully for any necessary consultation and must accompany the burner even if it is transferred to another owner or user, or to another system.
TECHNICAL DATA TYPE 482T1 482T58 Thermal power – output 95 – 240 kW – 8 – 20 kg/h Fuel Light oil, max. viscosity at 20 °C: 6 mm Single phase, 230 V ± 10% Electrical supply 50Hz Motor Run current 1.5 A Run current 2.2A 2750 rpm –...
INSTALLATION BOILER FIXING Put on the flange (1) the screw and two nuts, (see fig. 2). Widen, if necessary, the insulating gasket holes (5), (see fig. 3). Fix the flange (1) to the boiler door (4) using screws (2) and (if necessary) the nuts (3) interposing the ...
HYDRAULIC SYSTEMS Warning: before starting the burner make sure that the return pipe-line is not clogged: any obstruction would cause the pump seals to break. WARNING The pump is supplied for use with a two pipe system. For use on a one pipe system, it is necessary to remove the by-pass screw (A), (see figure).
ELECTRICAL WIRING 230V 50Hz WARNING Do not exchange the neutral with the phase. Switch with fuse 6A max. Regulating thermostat Limit thermostat with manual resetting Remote lock-out lamp (230V - 0.5A max.), if required Terminal block of control-box 530SE Valve Black Capacitor Motor...
COMBUSTION ADJUSTMENT In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjust- ment and testing must be carried out observing the instruction manual of the boiler, including verifi- cation of the CO and CO concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.

COMBUSTION HEAD SETTING : This is done when fitting the nozzle, with the blast tube removed. It depends on the output of the burner and is carried out by rotating the regulating rod, till the terminal plane of the blast tube is level with the set-point, as indi- cated in the schedule.

PUMP-PRESSURE AND AIR-FLOW The burner, in order to guarantee good smooth starts, irrespective of the type of boiler, is fitted with a hydraulic device which, independently of the control-box, reduces the fuel- and air-flow. At ignition, the pressure at the nozzle is 9 bar. After 4 - 6 seconds, it automatically increases to 12 bar. The air-flow, initially adjusted to the low setting, is, at the change-over of pressure, automatically brought to the air-flow required for the big flame.
AIR DAMPER ADJUSTMENT : The settings indicated in the schedule refer to the burner with its metal cover fitted and the combus- tion chamber with “zero” depression. These regulations are purely indicative. Each installation however, has its own unpredictable working conditions: actual nozzle output; pos- itive or negative pressure in the combustion-chamber, the need of excess air, etc.
