I just bought a new 50 gallon RHeem Water heater. After taking it out of the box I found a long piece of zig zag cut steel where flu gases come out of the tank. It's loose and just sits there.
What the heck is it.
 
It is a flu baffle.

A Flue Baffle is a helical piece of metal that works to slow down and aid the path of exhaust (flue) gases from the burner assembly, causing the gases to swirl on their upward path as they leave the unit.

Excellent replay and it makes sense. I looked all over the internet and could not find this piece and what it was used for.
Thanks again.
