Check combustion values with ignition load using flue gas analysis.
When curve points have been set, exit from the curve setting menu level, and set the
burner to operate at minimum load from manual operation menu level.

4.16 Activating FGR
Burners equipped with FGR can also be used without FGR. Whenever
you activate and deactivate FGR, you will need to recheck fuel–air ratio
curves.
FGR can be activated from:
Params. & Display
→
Flue gas recirc.
→
FGR mode
→
TC autodeact
→
It is recommended to commission the plant first without flue gas recirculation (FGR).
Thus the fuel-air ratio control system is set as if the plant operated without the FGR
function.
When all other settings have been made, create FGR curve points at ratio curve. The
FGR function will become active after you have stored the curve point settings.
During the time the curve menu is in use, the state of the FGR function does not
change. This means that the AUX3 for FGR is still at the
FGR closed
position until
parameter setting is completed.
The parameters for FGR mode have been set at the factory. The commissioning
personnel will adjust the settings at start-up if needed.
