If the boiler is gas fired (as opposed to electric) it still requires combustion air and has a chimney. Negative pressure in your home (from too many or too large of bath fans, dryers, kitchen fans etc) will suck air that is trying to be vented from your boiler into your home. That air, once burned 2X creates carbon monoxide, deadly.

I understand. The boiler is on the other side of the house and I will not be able to tee into its vent. If there are house vents or more added to the general area where the tank fans are sucking out, this should solve the pressure issue?
