@BESW nods the way I read it is that you have to hit/be hit by the fire elemental hard enough for it to count as an attack in order to catch on fire

but there are folks who apparently read it as "anything that touches the fire elemental makes a Reflex save against ignition"

@Anaphory well that would have been appreciated in this text as well XD

@Beanluc Hi!

You can find triangle tables in free Fate material like Masters of Umdaar.

@Shalvenay If you can find a creature which actually does set everything around it on fire, you might be able to use it as a counterexample.
