Also available with 8" (200mm) extension thermostat WARNING: Following installation, The valve lever MUST be operated AT LEAST ONCE A YEAR to ensure that the water-ways are clear. Certain naturally occurring mineral deposits may adhere to the valve, rendering it inoperative. When manually operating the lever, water will discharge and precautions must be taken to avoid contact with hot water and to avoid water damage. BEFORE operating lever, check to see that a discharge line is connected to this valve directing the flow of hot water from the valve to a proper place of disposal otherwise personal injury may result. If no water flows, valve is inoperative. TURN OFF THE WATER HEATER AND CALL A PLUMBER IMMEDIATELY. This device is designed for emergency safety relief and shall not be used as an operating control.
