Fresh air intake requirements for a gas water heater?
If the water heater is in the durnace room and the furnace room is
closed off from the rest of the basement ; the fresh air inlet may
still be required, depending on the size of the furnace room. You can
probably reduce it in size. I don't have my code books with me, but
SQLit may have all you need. Have him email it to you.
