How do you shut off the out-put on a gas hot water heater?

To shut off the output on a gas hot water heater, locate the gas control valve, which is typically found near the bottom of the unit. Turn the dial or lever to the "Off" position to stop the gas flow. Additionally, you can close the hot water outlet valve, usually found on the hot water pipe leading from the heater, to prevent hot water from flowing out. Always ensure safety precautions are followed when working with gas appliances.
