a good location to fire it. (not indoors, unless you have a dedicated studio and a very good vent) the location will need a Nema 50 -50amp plug to plug the kiln into... you will need a electrician to set up the plug if you dont have one alreadf--- the Nema 50 is not a 3 wire plug like a dryer, its a 4 wire plug like a stove/range.
