Etymology
The origin is uncertain, though a connection with words for flowing has been proposed. A flue originally meant a small furnace chimney connected to the main chimney.
In context
fumes go into the primary heat exchanger and then work it all the way in the bottom to the secondary heat exchanger where this motor is basically pulling out flue gases
