I own a 1964
Globetrotter and just purchased a "new" Suburban SF-30 furnace to replace the original furnace. I realize the cabinet space gives me plenty of room to work with and since this is the only Airstream I've owned that pre-dates 1972 I thought the current vent on the outside was the traditional two holed rectangle vent. It is not it is the large square vent. When I install the new furnace will I have to replace the old square vent, replace the aluminum over the gaping hole and then install a new smaller vent with two holes that line up with the exhaust of the new Suburban furnace? I have yet to receive the new furnace but am digging into the process far before replacing the old furnace to get a heads up from my number one resource at Air Forums. Has anyone on the forum done this on a 64 or older that can link me to some pictures if I have to replace the aluminum on the outside or pictures of the same vintage? Thanks so much for your time.
