In the United States, the R. W. Beckett “AF” 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.
