Kathryn, That head can be 7-6 off the wall. The limiting factor is the maximum allowable square footage per head. So if a head is 9-0 off one wall and 7-6 off the opposite wall the total allowable distance between heads in the perpendicular direction would be A=SxL or L=A/S or L=225/16-6 or L=13-6. Since the maximum that this head can be off a wall in this direction is 7-6 that limits the opposite direction to 6-0. Since these are maximums any configuration that doesn't exceed these limitations is acceptable.
