If that grate-covered hole is in a "common area" and up against a wall, you can bet that it was once a floor furnace. The combustion boxes on older gas floor furnaces would crack over time (decades) and become a carbon monoxide (CO) danger to inhabitants due to flue gas escaping into the home instead of going up and out the vent pipe.

You have a perfect opportunity to add a really ...

Before I added my ridge vent when we had consecutive days of 100F the attic could get up to 120-125 easy - and my roof is heavily shaded. I would come down completely soaked - like swimming pool soaked - when doing 15 minutes of electrical work. I just added a ridge vent to my attic a few months ago. Measured attic temperature after a couple of days in ...
