F0 Head required for proper combustion.

Low Firing Rate Baffle required (Beckett Part No. 3708). In the United States, the R. W. Beckett “AFG” Burner may be

equipped with Beckett’s “Inlet Air Shut-Off”, Beckett Part No. AF/A 5861, to increase efficiency. It reduces the amount of air passing through the oil burner, combustion
chamber, breeching, etc. up the chimney between burner cycles.

NOTE: THE USE OF THIS CONTROL CAN OCCASIONALLY CAUSE POST COMBUSTION NOZZLE DRIP.
