New Toilet install

I'm needing to install the Dometic 310.
I can only find info on a replace.
I need to know what the recommended distance to place the floor flange from the wall is.
Because of time and when the toilet will actually come in I don't have the toilet but need to place the flange this weekend.
Any suggestions would help. I have looked at the manual and dimensions and estimate at least 17in from the wall.
Thoughts?
