Unless you have a space heater that says "no venting required" the only furnace/ hot water heater that does not need venting is electric. ALL others need to be vented to prevent the occupants of the home from getting carbon monoxide poisioning. if the copper tubing is green near the fittings it could be from too much flux when it was assembled or a water leak that was addressed and the water caused the tube to oxidize.
