* Blower fan (7) draws in room air through both the burner tube (2) and an opening in the lid.(3)
* Air entering the lid is directed through a passage in the floating baffle.(4)
* The air is drawn across the surface (5) of the heated liquid, sweeping away the vapors as they break surface.
* The moisture saturated air passes through the draft diverter (6) and then mixes with the burner exhaust.
* The reduced mixture, environmentally safe, is drawn through the blower (7) and is released up the stack.(8)
* Free oils and oils whose emulsions have been thermally broken float to the surface. They are then evacuated via an overflow trough (9) into an external waste receptacle.
* Precipitated solids settle to the bottom and are easily removed at a convenient clean-out port.(10)
