boiler room exhaust vent
I am not 100% sure about what is going on but, if you are smelling fumes are they fumes from combustion, this would indicate that you already have an issue with negative pressure in the room.
How big is your boiler room?
Is there a blockage in the flue pipe of stack?
How well is the boiler insulated? and can you improve the R value of the boiler casing.
When its all said and done there is usually more said than done
