concentric vent question

I want to use a 2" pvc concentric vent [this is allowed by noritz for their unit]. every image I see of the vent shows the angled intake pointing upward. is it within code to have the angled intake pointing downward? I don't see the problem, but could use some input. thanks.

Many Codes require compliance with Manufacturers' Instructions. Might be good to scan and post that portion of the Instructions.
