Yes, I have the 56 Inch ones. I never use them on step 5 as it will you just blow away. One is installed in the Center of the Living Room (6mx4m) of our Guesthouse, switching on Aircon and Fan cools down the Room in no time.
When having a Gas Stove it is not a good idea to install a Ceiling Fan close by, I have had the same idea at time of planning my Kitchen but moved the Fan 2 meters away as he will blow out the Gas Flames very easy.
