This hole is about 1.5" in diameter, with a second much smaller hole at about 5 o'clock.
Both intake air (will sucknin plastic wrap held loosely near it)
A similar hole below has a black cap on it. Should there be a black cap on the one on the top?
Not seeing anything specific in my owner's manual. It's a Rheem.
