Vintage Air Installed - center vent blowing left?

[WannaBe68]

Just got my 69 Burb back from having a complete Vintage Air system installed. The guy did a great job and was very diligent in documenting the install. Driving it home and around some today I noticed the center vent, which I was hoping would blow towards the middle back is actually blowing directly at the middle of me in the driver's seat. Literally missing the right side of me and at my midsection. It's not even remotely blowing in the middle. Installer said the center vent blows to the driver side because of the way the tube is routed into the box behind the vent.
Anyone have a solution / fix or idea on how to get this center vent to blow in the middle?
Thanks!
