Kiddush/havdala during Seder and other fire questions

Maybe it’s posted somewhere… can you please explain details of havdala/kiddush motzei Shabbat?
No lighting candles so no Morei HaAish?
What happens if the yartzeit candle goes out over Shabbat? Can I light the stove?what if I forget to light the yartzeit candle?

Follow the siddur. Just skip Borei Me’orei Ha’esh

You got it

If it goes out, you can turn on the stove. (Gezera is - you should have done it before Yom Tov. And you did)

Don’t forget :wink:
If you forgot, don’t light it on Yom Tov
