boiler room exhaust vent

vnc72

My boiler room gets very hot when the boiler turns on. There is also a slight oder of fumes. I do have a fresh air vent to the outside. My question is, can I add an exhaust fan that turns on with the boiler and works with a timer for a delayed shutoff

That would risk putting the room into a negative pressure, and drawing fumes/more fumes from the flue/chimney. How big is the vent to the outside.

The vent is 8" x 16" . I was going to add a seperate vent to eliminate that problem

Do you by any chance live in a 10 story bldg.
If you live in a single family house you might just as well cut off the fuel supply and burn dollar bills instead.

Thanks for your input but I,m looking for an intelligent answer to my question

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.
