3.6
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. 20).
3.7
Electrode setting
Check the position of the factory set electrodes complying with
the Fig. 21.
Before removing or assembling the nozzle, loosen the screw
1)(Fig. 21) and move the electrodes ahead.
