80% gas furnace RUUD in a icyenene foamed attic - Need a combustion air vent solution

Inspector is telling me that the furnace needs access to fresh air. If I put a vent in the attic it will defeat the whole purpose of the upgraded insulation. Please give me your thoughts.

You should be installing a condensing furnace
