MOUNTING THE BURNER It is necessary that the insulating gasket (9, fig. 1) is placed between the boiler door and the burner flange. BURNER FIXING This insulating gasket has six holes, which, if necessary, can be modified as shown on the drawing on the right. D5242 Verify that the installed burner is lightly leaned...
OIL LINES 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 settings indicated in the schedule are valid for most cases. The setting of the fan output according to the installation should normally be done only through the air damper. Should one subsequently want to retouch also the setting of the combustion head, with the burner running, operate on the rod (1) with a 6 mm spanner (2) as follows: ), in order to increase the vol- Turn to the right: (sign...
