My Heat Exchanger & Wraparound Diagram.. Is This Right?

[LegendsCreekFarm]

I drew a quick diagram to show how I am installing my heat exchanger and wrap around pump.

I planned this according to what I could see on Central Boiler.  I have the taco wrap around sending water back to the bottom right port on the heat exchanger..    Is this considered counter flow?  (they said I needed to hook it up that way).

My plumber also said he thinks my taco wrap around needs to be facing the other way to reverse the supply and return.  I think this is wrong.  Opinions?

Both Taco and central boiler have all the arrows opposite of your drawing.
