Tools and Materials
Gather the necessary tools and materials before starting:

Step 1: Determine the Location and Mounting
Choose a location for the tankless water heater that allows for easy access to water and gas lines. Ensure there is sufficient space around the unit for ventilation and maintenance. Most tankless water heaters are mounted on a wall, so you’ll need to install a mounting bracket according to the manufacturer’s instructions.
Step 2: Connect the Water Lines
Run the water inlet and outlet lines to the corresponding connections on the tankless water heater. Use pipe sealant on all threaded connections. Ensure the water flow direction is correct by checking the arrows on the unit.
Step 3: Connect the Gas Supply
Connect the gas supply line to the gas inlet on the tankless water heater. Use a wrench to tighten the connection securely. Apply pipe sealant to all threaded connections.
Step 4: Install the Venting System (if required)
Some tankless water heaters require a venting system to remove harmful gases. Refer to the manufacturer’s instructions for specific venting requirements. Install the venting system according to the provided guidelines.
Step 5: Electrical Wiring
Connect the electrical wiring to the tankless water heater. Most units require a dedicated 120-volt or 240-volt electrical outlet. Ensure the wiring is properly sized and secured.
Step 6: Power Up and Test
Turn on the gas and water supply. Power up the tankless water heater and allow it to run for a few minutes. Check for any leaks or unusual noises. If everything appears to be in order, open a hot water faucet to test the water flow and temperature.
Step 7: Final Adjustments
If the water temperature is not to your liking, adjust the temperature setting on the tankless water heater. You may also need to adjust the gas flow rate if the flame appears too weak or too strong.
Tips for Success
