cut off the gas pipe valve, or the circuit breaker in the main panel for an electric heater
Electric heater is always turned off at circuit breaker, but heater receives no heat and tank can freeze. To prevent freezing while on vacation, turn off electricity, open cover(s) on front of water heater, use a screwdriver and turn down thermostat(s). Thermostats will be marked with temperature so when you return from vacation, rotate temperature back to original setting, or save money by setting temperature lower. Be sure to put insulation and covers back on each time so thermostats read correct temperature.
Gas heater: Depends on why you want to turn off water heater.
Going on vacation, simply rotate large dial on front of gas control valve until "vacation" is at top. This will keep temperature at 50 degrees F and prevent freezing. Then when you return from vacation, rotate dial back to original position. Take photo of dial so you remember original position since markings on valve are not specific. The advantage of rotating dial is that pilot light stays lit.
If you want to turn gas completely off, then the pilot light will go out, and the tank receives no heat. To turn off gas, go to gas control valve where large temperature-setting dial is located. There is a 1/2" - 3/4" gas line that connects to side of gas control valve. The gas line can be flexible pipe or rigid black pipe. Follow the gas line a short distance and you will find a brass shut-off valve. The brass valve has a rectangular piece on top where a crescent wrench fits. Rotate the rectangular piece 1/4 turn. Once the rectangular piece is perpendicular to the direction of the gas line, then the valve is off.
