Noritz tankless water heaters are renowned for their energy efficiency and endless hot water supply. However, igniting them can be a daunting task, especially for first-time users. This comprehensive guide will provide step-by-step instructions on how to light a Noritz tankless water heater, ensuring a safe and successful ignition process.

Safety Precautions

Before attempting to light the water heater, ensure you take the following safety precautions:

• Turn off the gas supply to the water heater.
• Open a hot water tap to release any trapped air or gas.
• Ensure the water heater is properly vented to the outside.
• Keep all flammable materials away from the water heater.

Step-by-Step Lighting Instructions

1. Gas Valve and Pilot Light Knob

Locate the gas valve and pilot light knob on the front panel of the water heater. The gas valve is typically a lever or knob that controls the flow of gas to the burner. The pilot light knob is usually a small knob with a red indicator light.

2. Open the Gas Valve

Slowly turn the gas valve clockwise to open the gas supply. You should hear a hissing sound as gas flows into the water heater.

3. Light the Pilot Light

Press and hold the pilot light knob for 20-30 seconds. While holding the knob, use a lighter or match to ignite the pilot light. The red indicator light should illuminate, indicating a successful ignition.

4. Release the Pilot Light Knob

Once the pilot light is lit, slowly release the pilot light knob. The flame should remain lit without any assistance. If the flame goes out, repeat steps 2-4.

5. Turn on the Burner

Turn the gas valve fully clockwise to open the gas flow to the burner. You should hear a clicking sound as the burner ignites.

6. Adjust the Water Temperature

Use the temperature control knob to adjust the desired water temperature. The knob is typically located on the front panel of the water heater.

7. Check for Leaks

Once the water heater is lit, check for any gas leaks around the gas valve and burner. If you detect any leaks, turn off the gas supply and contact a qualified technician immediately.
