Eric,

There are 2 separate screened vents. They are too small and they are not within 12 of the floor or ceiling, but that is not my primary question. My primary question was; can the two combustion air vents both go to the same foundation crawlspace area? My Code Check seems to indicate no, but the IRC does not.
