How far away does the exhaust and intake on a 90 plus furnace have to be from the vent pipe on a power-vent water heater?

Hi John,
Part of the answer is in water heater power vent post – min 36" above the forced air inlet if closer than 120" horizontally to the inlet – this for US installations, clearance to a non-mechanical air supply inlet to the building or the combustion air inlet to any other appliance shall be 4 feet below or to side of opening; 12" above opening.
