Kinetic Blast + Detonation

[Brotter24]

I wanted to get some clarification on a form infusion from the Psychic Anthology. Detonation, it states "Flames explode outward from your body, dealing your blast damage to all creatures and objects within a 20 foot radius." I have a fellow player saying that that will injure the kineticist that casts/manifests the blast as well as those within 20 feet of the kineticist. I am of the thought that a kineticist cannot be harmed by their own kinetic blast. Am I wrong, or is my fellow player mis-interpreting the infusion?

I am unfamiliar with Detonation, but if the wording is 'outward from body', that means the blast starts on the kineticist's outer surfaces and goes outward.

=> No damage to the kineticist. A cruel GM would say that it damages your clothes/armor, but that makes the the whole thing rather pointless.

Pretty sure they'r confusing the spell "detonation" with that ability.
The spell does harm the user.
but this ability is not the spell-even if rather similar.
