Hi,
What I have heard is..
It might be too 'windy' for any cooking. i.e. heat get dissipate away, affecting the cooking. Or might cause 'gas leak' if it get too windy during cooking. (pardon my lousy expression. )
I think this is quite a scientific reasoning.
And if you choose to close the windows during cooking, your whole house will smell.
Another thing I heard is..
Stove should be kept away from public viewing. i.e. if it is facing the windows, others that live near you or walk pass your kitchen, might be able to see it.
As for reasoning, stove is the place you cook your meal. Food = your wealth. Not to be seen by others.
Correct or not, I'm really not sure. Just sharing only.
Cheers!
