Stack height?

[mike z]

I've heard it recommended 2x the evaporator length as a rule of thumb to est. stack ht. Instead of a fan, could I go higher with the stack or is there a limit to the benefit this would have?

You will continue to gain as it gets taller with "diminishing returns".

Go higher, just be sure to put marker lights on it if you get above the tree line, so aircraft see it.

:lol: ... now there's a photo I'd like to see. I picture an unsupported stack that high as looking like something one would see in a Dr. Seuss book.

That's just what I was hoping to hear. Thanks.
