To actually start a fire, choose a random location and random time.
Then set a timer.
Certain types of explosions are more like fires then actual exposions.
Some are also invisible, but you see the afteraffect fires.

Just test out explosions to find the right one.

Sometime I am planning to make a fire script, a little more complicated then this, that will make huge fires but I don't have time atm.
