2 Post lift location question....

A few months ago I bought a used Atlas 10k lb, asymmetric, 2 post lift. I'm now at the point in the shop where I need to get it installed. My shop is configured as in the picture below so my question is simply, how far from my door should I set the posts? My initial thought was around 12ft.

EDIT: Door in front of that location is a standard overhead door, 10 ft wide and 12 ft tall. The walls (eaves) are 14ft
