Air damper adjustment

The air damper is set in factory. This regulation is purely indica-

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.
Main air damper

the positions of the damper, proceed as follows:
 Remove the secondary air damper (B) loosing the screws
(1).
 Loosen the screw (2) and rotate the main air damper (A) to
the required position.
 Retighten the screw (2) and put back the secondary air
damper (B).
