I like it. Simple, to the point, good colors, leaves you a lot of leeway to use it in a variety of ways and you didn't go with anything tacky like a lit fuse for the underline - bonus points for that<g>

The only thing I can say, and this is terribly nitpicky, is just from a balance standpoint you might turn the yellow into more of an upsweep with the thickest part under 'fire' rather than the middle unless you were going for a rising/setting sun image rather than an accent?

At any rate, it is a lovely logo :)
