Operating Instructions

1. Turning On: Ensure the gas supply is open and batteries are installed. The unit should display the current water temperature or a standby indicator.
2. Adjusting Water Temperature: Use the "WATER" control knob to set the desired hot water temperature. Turning the knob clockwise typically increases the temperature.
3. Adjusting Gas Flow: Use the "GAS" control knob to regulate the gas flow, which affects the heating intensity. Adjust this in conjunction with the water temperature for optimal performance and efficiency.
4. Hot Water Delivery: Open a hot water tap. The water heater will automatically ignite and begin heating water as it flows through the unit. The display will show the current output temperature.
5. Turning Off: To turn off the unit, close the gas supply valve. For extended periods of non-use, it is recommended to also drain the water heater to prevent freezing.
