As the others have said, the roof unit is electric and does not use propane or a pilot light. However, there will also be a furnace down near floor level that does use propane and, in that vintage, almost surely has a pilot light. It may look something like this:
Atwood Everest Star 7900 II Furnace, 12,000 BTUs
In that era, there is probably no wall thermostat and the pilot light will be behind the metal grill on the front of the furnace. If you can identify the make and model of the furnace, we can help you with lighting instructions and probably even find an owner manual online.
