That antique is costing you a lot of money. A 90%+ efficiency home furnace will bring in combustion air and the exhaust is so cool it goes out through a schedule 40 PVC pipe. No chimney required and only about 7% of your fuel is wasted. Some old furnaces are 60% efficient which means 40% of the fuel you pay for is wasted.
Sorry, I didn't explain myself very well. My home furnace is only about 8 year old and when I said "chimney" I should have said the exhaust goes out of the house through a PVC pipe. No fresh air intake though.
