Boiler room ventilation

my boiler room is 5x20. i havent installed the fire rated steel door yet (still finishing the basement). i have 5/8 sheetrock on the ceiling and the wall that separates it from the main room. i have oil heating and a hot water tank. the boiler vents out thru the wall to the chimney. the foundation walls in the boiler room are not sheetrocked. i framed the whole basement about 6" from the foundation walls, so the boiler room is not totally sealed. u can see from one side of the basement to the other (hopefuly you got the picture of what im talking about).

question: do i need to install fresh air vents to the outside? if so, please give me an idea of how many, where they should be positioned, etc. i do not want to put vents in the door. thank you.

YES!! Any heating system that uses fire must have a source of air. It will draw it from inside the house or, if provided, an outside source. Outside air is much more energy efficient.
