Electrode Setting; Burner Start-Up Cycle - Riello Burners 40 G20 Manuel D'entretien

It is important to take account of the fact that the air
output of the fan differs according to whether the
burner has its metal cover fitted or not.
Therefore we recommended to proceed as follows:
– adjust the air damper as indicated in the schedule (4);
– mount the cover, simply by means of the upper
screw;
– check smoke number;
– should it become necessary to modify the air out-
put, remove the cover by loosening the screw,
adjust the air damper, remount the cover and finally
recheck the smoke number.
NOTE: When the burner works at a firing rate
higher than 17 kg/h remove the panel
fitted inside the metal cover. (See figure).
