Air damper adjustment

The air damper is set in factory.
This regulation is purely indicative. Each installation however,
has its own unpredictable working conditions: actual nozzle ou-
tput; positive or negative pressure in the combustion-chamber,
the need of excess air, etc.
All these conditions may require a different air damper setting
(see Tab. A).
The purpose of this damper is to perform a fine-tuning of the in-
let air. Tuning of this device is possible acting of the
screw 1)(Fig. 21).
