[passive] burn out / is put out / is blown out

I found some part of the sentence below from my book weird.

We turn off (or put off, switch off, click off) lights, but a candle burns out or is put out or is blown out. A candle can also burn down.

Q) Why "burn out" is not in passive voice as "is put out" and "is blown out"?
Is the passive voice here nothing to do with "be + past participle + by something/someone"?

Because a candle, unlike a light, can turn itself out by burning out. (A light can do this, too, but it is a one-time operation after which you need to replace the bulb.)
