It's actually fire created by particles. It's just found under the dynamic menu set. If you switch to dynamic menu set, it's under the effects menu. There's smoke, fire, lightning, shatter, etc. If you select an object and then click on fire, it creates an emitter. There are plenty of particle attributes you can play with but no matter how much I fooled with them, I just couldn't get a realistic looking fire.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
