The blue flame will be rendered light, as the heat will be hot enough for HIE to
record it.  I would try to not light the surrounding area, as it will almost
certainly wash out the image.  Do some testing, as the IR emitted by the flame
"might" light the surrounding area itself (I don't know your setup).
