Combustion air intake for SBI inserts?

[Easy Livin’ 3000]

Anyone know where the combustion air intake is for the 2.4 firebox class Drolet/Century/Osburn inserts?

I'd been under the mistaken impression that the intake was on the sides, where the knockouts were for the OAKs.

Usually you leave the OAK knockout open, for inside air.

I thought the same originally. Take your fan off and you'll see it underneath the firebox. This is where the OAK inlets dump into.

I've looked when I had the fan off and couldn't decipher it, as it's mostly thin slots cut into the steel. I'll have to take another look next time I have the fan off.

What I'm trying to figure out is whether there's a way to block some of the area off to reduce the airflow when we have an overly strong draft.

There's an intake scoop attached to the bottom of the firebox, at least on mine. The fan blows the air below that and then up and over.
