Air damper adjustment
The air damper is factory set according to the values indicated in the
burner settings table for the relevant burner (tables 13 and 14). The
adjustments are for guidance only.
Each installation, has its own unpredictable working conditions: actual
nozzle output; positive or negative pressure in the combustion chamber,
the need for excess air, etc.
All these various conditions may require a different air-damper setting.
The damper is used to precisely adjust the input air flow rate.
▶ Adjust the air damper [2], the setting is displayed in the window [1].
