I want to flush my tankless water heater (DIY).

I've never read plumbing schematics before.

Which one of these is the "V1" value they are referring to in the doc?

(And have I correctly identified all the values??)

Manual and my system

P.S. The values I circled look like threaded ports, but the diagram leads me to believe V1 is to to the left.

EDIT: Another view

EDIT2: This is how I flushed it and it worked!

My setup
