You need to find out the model number and follow the manufacturer's recommendations.

Not the ansewer your looking for, but there has to be room to service the unit, there needs to be 5/8 fire rock on the walls, and enough free air flow getting to the furnace for combustion. A louvered door would do it.
I like to use a 36" door so if the unit ever needed to be replaced you do not have to tear down a wall to get it out.

from what i remember it depends on what side of the furnace the wall is on.. on the air intake its 12". any side that has parts that need to be serviced. i.e burner. filter leave more space so the technician can get at it easily

Everybody's answers are incorrect, follow Manufacturer's instructions.

The clearances may be inside the unit or on the service door inside face (otherwise follow post #2 and #6). Your local Building Department may have specific requirements for the combustion air supply, ducting, etc.; pp. 2, and 3, not just a louvered door: http://www.mybuildingpermit.com/Insp...0checklist.pdf
