I know that the 4 - 6 inch distance is how they are shipped but I strongly feel that the distance is too large and it greatly hinders the efficiency of the burner. I would direct the OP to this thread
that discusses influence of this large distance on the burner's efficiency. For a $20 bill I had my burner modified so that the distance between the burner and kettle is around an inch. The difference is night and day in terms of burner efficiency and propane use.
