On our Thetford (can't remember the model) the doughnut seal had to be correctly lined up.  There was an llustration on the pack.

As an aside, we always left a bit of water in the bowl to act as a barrier to any pongs.

Thetford casette toilets are designed to be left dry with no water in the bowl! They seep water if you leave them wet.
