I found the service manual for HEHR windows not the ones used on the Springdale. I have been looking at so many things today regarding my window issue. Sorry!
The HEHR window service manual can be found at

I did get in installation instructions from Kinro. It stated that installation clips should be in place for proper centering in the opening. 2 clips on the sill and one on each jamb.
Something is really wrong with my two windows, the top of the rough opening shouldn't be just below the edge of the flange.
Hopefully the dealer will let me watch and take pics when the windows are removed.
