Chevra, after some research (and learning), allow me to pose the following question : the gemoro says (shabbos 123) that you can be “kofin kaarah al haner shelo teochez es hakoreh”- you can cover the candle with a cover so that the ceiling does not catch fire’ (there is your answer ICOT)as it is considered gram kibui (on shabbos nonetheless) The rambam paskens accordingly.
so , my question is simple: how is that gram kibbui? We got to say that it is because the fire is starved of oxygen and goes out by itself. how is that DIFFERENT than starving a stove from gas?Please elghten us because the more i eelve into this sugya the more i become convinced that shutting of fuel supply is only a gram and this applies to gas to the stove too.
