Your coach would have a regular ducted furnace that is typically hidden in one of the cabinets. The key will be locating the cabinet, and then locating the pilot access hole on the furnace. With my 1978 Minuet, the wall thermostat for the furnace is set so that the blower motor starts to blow . . . then the pilot is lit following the instructions on the furnace access panel. One caution I would give is to have a qualified service technician inspect the furnace as furnaces of this vintage often have rust-out problems in the heat exchanger which are essentially irrepairable.
If you have a device that is similar in appearance to the unit in the 1964
Bambi II in this discussion, it is more likely a Catalytic Heater. During the 1970s, catalytic heaters were available as options on Airstreams. I am not certain whether these were factory installed or dealer installed, but they were comparatively common. They were popular with those who boondocked as they required no electricity to operate. Some were vented, but most were non-vented so it was necessary to crack open a roof vent and at least one coach window when the catalytic heater was in operation.
If you are looking for manuals for your coach, you can find the basic owners' manual and factory service manuals through the Airstream Factory Store. The owners' manuals can be found at this link
, and the service manuals can be found at this link
. There is also a vendor on E-Bay who offers some of the owners' manuals and services manuals on CD-ROMs.
Good luck with your coach!
