Step-by-step guide on how to light the pilot light on your gas water heater

Step 1. Locate the Control Panel. At the bottom front of the unit, find a small door that can be removed. Lift and move it aside.

Step 2. Review the Instructions. On the back of the door, you should find the lighting instructions. Keep these handy as a reference.

Step 3. Set the Controller. Check the current setting on the controller, which should indicate the temperature setting. The system will be set on a specific number (like '4') if it's out.



Step 4. Prepare to Ignite. Turn the dial to the 'ignition' position, indicated by a little spark symbol.

Step 5. Ignite the Pilot Light. Press and hold down the main control button at the top. While holding down the button, use your other hand to press the piezo igniter. This action will create a spark to light the pilot. Continue to hold the main button and look underneath the control panel to check for a small blue flame indicating the pilot is lit. Keep the main button pressed for about 30 seconds to ensure the pilot light stays lit after releasing the button.



Step 6. Adjust the Temperature. After confirming the pilot light stays on, slowly turn the dial anti-clockwise to increase the temperature setting to your desired level.


Step 7. Once the main burner ignites, replace the cover securely. Turn on a hot water faucet in your home to check if the system is now properly heating the water.

If the pilot light does not stay lit, the burner does not ignite, or you experience other issues, contact your local gas technician. For emergency services in Adelaide, you can contact Best Plumbing Maintenance Adelaide at (08) 8261 0165 or text/call 0411 783 681.
