Generally, on Yom Tov one is allowed to light a gas burner (using a pre-existing flame), but is not allowed to turn off the gas burner. This is because one may light a fire on Yom Tov, but not extinguish it (see here or here for details).
Somebody told me that on Yom Tov, in order to turn off the gas on a stovetop, one is able to put a full pot of water on the stovetop. When it boils, it will overflow and extinguish the flame. One may then turn off the gas, since doing so does not extinguish the flame.
This doesn't sound right to me. This footnote seems to imply the opposite:
Extinguishing a fire is forbidden. Even indirectly; for example, by placing a burning candle where the wind might blow it out.
However, that footnote is unsourced, so I'm not sure where to look it up.
Has anyone seen a source of whether this practice of boiling water to extinguish a flame is forbidden or permitted? Can someone provide a source where putting the candle in a position where the wind can blow it out is forbidden.?
