That and just turn the pilot flame off and the gas to the heater. Then when your done just let things air out a bit before relighting the pilot, and wear a mask, seen to many guys just walk into a booth and start spraying with no protection, ventalation is good but no substitute for a mask, and I don't mean a cheap dust mask, get one with replaceable filters and it will last a long time think their about 15-20 bucks 3-M makes a decent one, good investmant for the lungs.
