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 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 indicated in the schedule.
AIR DAMPER ADJUSTMENT : The mobile air damper (1) operated by the jack (2) assures the complete opening of the air intake. The regulation of the air-rate is made by adjusting the fixed air damper (3), after loosing the screws (4). When the optimal regulation is reached, screw tight the screws (4) to assure a free movement of the mobile air damper (1).
