If there are no vents in the viv, you'll need to wait, I'm afraid, especially as the temps and stat will have to be adjusted once the vents are in place. And you don't want to install him and then have to disrupt him all over again when you do the vents.
I know it's awful to have to wait, but it's for the best, honest.
Im guessing you'll be using vents around 2.5". Mark up a hole in pencil that your vent will sit in, drill smaller holes within that circle and bobs your uncle. I'd start with the centre hole, will be used as a pilot for the hole cutter anyway.
Not just a pretty face me!

I made a guide that I could hold into the corner so all my vents are in EXACTLY the same position, I decided to use 2 smaller vents rather than one bigger one, I just though tit would look better.
I took this the other day and it shows my vent layout. They are 350mm vents.
