I suggest that you check the Ducting very good. Our '82 has a Suburban Furnace under the Couch like you are describing. The outside is for the burner section and yes it does vent and that is where I found a wasp nest in the squirrel cage.
The air that is heated is brought in from the inside just behind the driver's seat and after getting heated goes through the ducting on each side of our couch. The ducting is held together using duct tape and after the years that wasn't in all that good of condition. Ours was leaking through some of the joints so I re-wrapped all of the ducting while reconditioning ALL of or furnaces.
Without getting a good look I am only speculating. Keep in mind that if one has a problem the others MAY as well.
