If you are installing a gas water heater, follow the manufacturer's guidelines for connecting the gas supply line. It is crucial to ensure that all electrical and gas connections are made correctly and safely to prevent any potential hazards.

13. Fill and Test

Once the power source is connected, it is time to fill the tank with water and test the system. Open a hot water faucet in your home and allow the air to escape from the tank as it fills with water. Once water flows steadily from the faucet, close it and check the tank again for any leaks. This process ensures that the tank is properly filled and that there are no leaks in the system.

14. Adjust Temperature

With the tank filled and tested, you can now adjust the temperature setting on the water heater to your desired level. Follow the manufacturer's instructions carefully to set the temperature correctly. It is important to find a balance between energy efficiency and comfort, ensuring that the water is hot enough for your needs while not wasting energy by setting the temperature too high.

15. Do Final Checks

Before considering the installation complete, it is crucial to perform a final round of checks. Double-check all connections to ensure they are tight and secure. Verify that the tank is properly positioned and stable in its designated location. Finally, confirm that the water heater is functioning correctly by testing the hot water at various outlets in your home. Once you are satisfied that everything is in order, you can restore the power or gas supply to the water heater and enjoy your newly installed hot water system.
