INSTALLATION THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS. 3.1 BOILER FIXING Put on the flange (1) the screw and two nuts, (see fig. 3). Widen, if necessary, the insulating gasket holes (4), (see fig. 4). Fix the flange (1) to the boiler door (3) using screws (5) and (if necessary) the nuts (2) interposing the insulating gasket (4), (see fig.
3.3 HYDRAULIC SYSTEMS Fig. 7 WARNING: The pump is designed to allow working with two pipes. In order to obtain one pipe working it is necessary to unscrew the pin (2), remove the by-pass screw (3) and then screw again the pin (2), (see fig.
3.4 ELECTRICAL WIRING NOTES: WARNING – Wires of min. 1 mm section. DO NOT EXCHANGE NEUTRAL WITH PHASE (Unless requested otherwise by local standards and legislation). 50Hz 230V – The electrical wiring carried out by the installer must be in compliance with the rules in force in PE L the Country.
WORKING 4.1 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. To suit the required appliance output, choose the proper nozzle and adjust the pump pressure, the setting of the combustion head, and the air damper opening in accordance with the following schedule.
4.3 COMBUSTION HEAD SETTING, (see fig. 12, page 6) It depends on the output of the burner and is carried out by rotating clockwise or counterclockwise the setting screw (6) until the set-point marked on the regulating rod (7) is level with the outside plane of the nozzle-holder assembly (1).
HIGH-FLAME SETTING, (see fig. 14, page 7) AIR-DAMPER ADJUSTMENT Loosen the nut (3), turn the screw (1), until the indicator (2) is in the required position. Then, lock the nut (3). PUMP-ADJUSTMENT This is set at 15 bar at the factory. The pressure gauge must be mounted in place of plug (4, fig.
FAULTS / SOLUTIONS Here below you can find some causes and the possible solutions for some problems that could cause a fail- ure to start or a bad working of the burner. A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box (3, fig.
