Air damper adjustment

The air damper is factory set according to the values indicated in
Tab. F.The adjustments are for guidance only. Each installation
however, has its own unpredictable working conditions: actual
nozzle output; positive or negative pressure in the combustion-
chamber, the need of excess air, etc.
All these conditions may require a different air-damper setting.
The damper 1)(Fig. 8) is used to precisely adjust the input air flow
rate.
 To modify the calibration, adjust the screw 2) as shown in
Fig. 8.
