Ensure that you have a clear workspace and that you are familiar with the installation process. If you are not confident in your ability to perform the installation, it is recommended to hire a professional plumber.
Step 1: Plan the Installation
Start by planning the installation location. Ensure that the area is well-ventilated and that the Navien tankless water heater is placed on a flat, stable surface. The unit should be easily accessible for maintenance and repairs.
Step 2: Connect the Gas Line
If your Navien tankless water heater is gas-powered, you will need to connect the gas line. First, turn off the gas supply to the home. Then, use the appropriate gas line connectors to connect the gas line to the gas valve on the tankless water heater. Make sure to use Teflon tape to secure the connections and check for leaks.
Step 3: Connect the Water Supply Lines
Next, connect the water supply lines to the tankless water heater. Turn off the water supply to the home and use the water connectors to attach the water lines to the appropriate ports on the unit. Again, use Teflon tape to secure the connections and check for leaks.
Step 4: Install the Drain Pan and Overflow Tube
Mount the drain pan under the tankless water heater and connect the overflow tube to the drain. This will help prevent any potential water damage from leaks.
Step 5: Ventilation
Ensure that the tankless water heater is properly vented. Navien tankless water heaters require a direct vent system, which can be either concentric or twin pipe. Follow the manufacturer’s instructions for installing the venting system.
Step 6: Power and Gas Connections
Connect the power supply to the tankless water heater according to the manufacturer’s instructions. If your unit is gas-powered, make sure the gas valve is open and the gas pressure is within the specified range.
Step 7: Testing and Final Adjustments
Once all connections are made, turn on the water and gas supplies and test the tankless water heater. Adjust the temperature settings and ensure that the unit is functioning correctly.
Conclusion
Installing a Navien tankless water heater can be a rewarding project for those with the necessary skills and tools. By following these steps, you can enjoy the benefits of a more energy-efficient and space-saving water heating solution in your home. Remember to consult a professional plumber if you are unsure about any aspect of the installation process.
