Am I correct in thinking that since the pilot flame is always on a gas stove, if one “turns on” the burner knob, it is simply an extension of the fire and not a new one, and hence one would be allowed to operate it/cook on tom tov?
Can you please clarify what you mean by “lighter to start the flame” in your response? The stove has an electric starter, but I plan on unplugging it and turn the gas on using a pre-existing fire.
You can shut it as long as you don’t raise the flame first.
Many stoves go from low to high to off. In that case, best thing to do is blow out the flame and then turn the knob off.
