Fresh air vent

I am either too lazy or too stupid to find a recent thread on fresh air vents for boiler rooms. I want to convert the fresh air vent from a sidewalk hatch with a bunch of holes drilled in it (yes, it seems to be legal after many years of inspections), to an internal air shaft running up to the roof (4 stories). Said air shaft is not air tight as it has panels on each floor for accessing the water riser that also runs in the shaft. The air shaft is topped with a well vented skylight enclosure. Do you think it’s legal if the fire proof damper is installed at the boiler room?
