That might have been me. I set up my heat box to draw air in through
side vents. Particularly with fresh air ram blocked. Here's some pics
I threw up. Might shed some light

Somewhere I have a video showing air flow when tested on bench. When
fresh air ram was blocked even by 1/2, a lot of air was sucked in
through the side vent holes.

In theory it recirculates cabin air with fresh air duct closed or
partly closed. I never did get around to making a proper control flap
for fresh air ram, but did mount one that fit. It just sealed poorly
and I got bored with the project.
