Air damper adjustment

The air damper is adjusted in the factory.
This adjustment is purely indicative. However, each installation
has its own operating conditions: nozzle flow rate, positive or
negative pressure in the combustion chamber, air excess re-
quirement, etc. All these conditions can require different adjust-
ments of the air damper.
Only for code 20091750
The adjustment of the air is carried out using two
independent dampers (Fig. 12).
