I'm sorry the spam guard caused you complications. I will format your question and my response in the original question.
You are right, I should have written "According to the Shulchan Aruch and Sefardi practice it does not help for a Jew to only light the fire; he must place the food in the place where i will be cooked". However I would point out that this applies only when the fire is lighted before the food is put in place, such as when one preheats an oven to roast meat. However, if one places a pot on the stove and afterwards ignites the fire, certainly the important act in this case is igniting the fire and that is what must be done by a Jew.
