In your newsletter that I saw through Agudas Yisroel Bais Binyamin, you point out that it is only permitted to lower or shut fire on a stove on yom tov if you cant move food elsewhere. I had spoken to a well known posek in Brooklyn, whose son grew up in Reb Moshe’s ztzal house and he advised me that on a gas pilot stove where all you are doing is closing off the delivery of gas to the burner, thus the fire ceases to exist, you are allowed to close it for any reason-this according to Reb Moshe. Did I misunderstand him or is there a “tzad” heter to this. Thank you in advance for your reply.
Answer:
I think that you misunderstood. Rav Moshe is lenient and permits lowering the flame for purposes of continuing to cook, but not extinguishing the flame altogether when the pot can simply be removed from the fire.
Please see Iggros Moshe, Vol. 4, no. 103.
