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 447T2 Thermal power – output 26 / 35.5 ÷ 66.4 kW – 2.2 / 3 ÷ 5.6 kg/h Gas oil, max. viscosity at 20 °C: 6 mm 2 /s (1.5° E) Fuel Electrical supply Single phase, 230 V ± 10% ~ 50Hz Motor Run current 0.75 A –...
FIRING RATE D8791 Light oil output - kg/h Thermal power - kW DIMENSIONS Flange Burner D4646 BOILER FIXING It is necessary that the insulating gasket is placed between the boiler door and the burner flange. This insulating gasket has six holes, which, if necessary, can be modified as shown on the Fig.
HYDRAULIC SYSTEMS before starting the burner make sure that the return pipe-line is not clogged: WARNING: any obstruction would cause the pump seals to break. SYSTEMS NOT PERMITTED IN GERMANY L meters I.D. I.D. meters 8 mm 10 mm D5493 D5809 WARNING The pump is supplied for use with a two pipe sys-...
ELECTRICAL WIRING WARNING: do not exchange the neutral with the phase. Fig. 3 230V ~ 50Hz 230V 50Hz NOTES Wires of 1 mm 2 section. The electrical wiring carried out by the installer must be in compliance with the rules in force in the Country.
COMBUSTION ADJUSTMENT In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and testing must be carried out observing the instruction manual of the boiler, including verification of the CO and 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 installa- tion 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 run- ning, operate on the rod (1) with a 6 mm spanner (2) as follows: TURN TO THE RIGHT: (SIGN +)

PUMP PRESSURE AND AIR OUTPUT (Fig. 6) The burner is provided with an hydraulic device controlled by the economizer which reduces to approx. 70% the max. output of gas oil and air. Fig. 6 D8384 STAGE ADJUSTMENT (with selector on Pos. 1) Adjustment of air shutter: Unloosen the nut (9) turn the screw (10) until the air shutter (1) reaches the position desired.
FUEL HEATING In order to obtain smooth starting and operation across its output range the burner is fitted with an electric resistance, which heats up the gas oil in the nozzle line. This resistance is energized when the thermostat calls for heat and after a delay of approximately two min- utes depending on room temperature, the motor will start.
FAILURE DETECTION ON HEATING DEVICE NORMAL OPERATION (Fig. 8) The plug fitted in the panel is placed in the position corresponding to “Resistance ON” When the remote control closes, the LED lights up and, after about two minutes, the burner starts up. BURNER DOES NOT OPERATE 1) If the LED is OFF, the heating resistance placed in the nozzle-holder is off.
WARNINGS TO AVOID BURNOUT OR BAD COMBUSTION OF THE BURNER – When the burner is stopped, the smoke pipe must be opened and effect a natural draught in the combustion chamber. If the smoke pipe is closed, the burner must be drawn back till the extrac- tion of blast tube from the furnace.
