Fan boundary conditions are usually applied to interior faces...where there are cells on both sides, I m not sure whether it is applicable to a face at boundary?

To get an interior face you have to split one volume in to two using a face with connected option turned on, Now you can mesh the model and define the common face of the two volumes as interior boundary. you can change this to fan in Fluent
