Be advised that the propane furnace fan will operate very well using the connection you described, however, it will not warm the camper unless you have propane turned on as well so that the furnace will actually ignite and produce warmth to be distributed throughout the camper by the aforementioned furnace fan that will operate quite well with the connection you described. Have a nice day!

Oh, and welcome to the forums.
