3.3 Function
3.3.1 Air supply
Air damper
The air damper regulates the air quantity required for combustion. The combustion
manager drives the air damper via actuator. At burner shutdown the air damper
closes automatically. At burner shutdown the air dampers close automatically.
Fan wheel
The fan wheel supplies the air from the air intake housing to the combustion head.
Diffuser
The air gap between flame tube and diffuser is adjusted by positioning the diffuser.
This adjusts the mixing pressure and the air quantity required for combustion.
Air pressure switch (optional)
Depending on the burner application, optional equipment may be required for op-
timum operation [ch. 12.3].
The air pressure switch monitors the fan pressure. If the fan pressure is insufficient,
the combustion manager initiates a lockout.
