It's pretty easy, but first finish the Elite Four. When you go to Floarama town, move to the right (not into valley window works, but the route before it) and then surf, keep moving right and there! Fuego Ironworks! I'm not sure if it can be acsessed without finishing Elite Four.
Enjoy!

Sometimes they're in a swarm at Fuego Ironworks (ask dawn's sister after you beat the elite four)
in front of fuego ironworks
You go to Fuego ironworks then use the poke radar there and it should appear in the grass.
Quite simple, go to the place where there are 4 panels in a column, then go to the top one, battle the trainer, then go to the panel which leads to Mr. Fuego.
