Where is the pilot button on A.O. Smith water heater?

The location of the pilot button or pilot light ignition button on an A.O. Smith water heater can vary depending on the specific model and type of water heater you have. A.O. Smith produces both gas and electric water heaters, and the pilot button is typically found on gas-powered models. Here's a general guide on where to locate the pilot button on a gas A.O. Smith water heater:

Before you begin, please note that working with gas appliances can be dangerous if not done correctly. If you are not comfortable with these procedures or if you are unsure about any aspect of your water heater's operation, it is recommended to consult the user manual or seek professional assistance.

1. Identify the Water Heater Type: Determine whether you have a gas-powered A.O. Smith water heater. Gas water heaters are equipped with a pilot light, which requires a pilot button for ignition.
2. Access the Control Panel or Access Door: Most gas water heaters, including A.O. Smith models, have a control panel or an access door on the front of the unit. The pilot button is usually located behind this panel or door.
3. Remove the Access Door: If your water heater has a hinged access door, use a screwdriver or the appropriate tool to remove any screws securing the door in place. Once the screws are removed, swing the door open to access the interior components.
4. Locate the Gas Control Valve: Inside the access panel, you will find the gas control valve. This valve is responsible for regulating the gas supply to the water heater, including the pilot light.
5. Identify the Pilot Light Area: Near the gas control valve, you should see the area designated for the pilot light. This area typically includes a small tube or pipe that leads to the pilot burner, along with a knob or button for igniting the pilot light.
6. Locate the Pilot Button or Ignition Knob: Depending on the model, the pilot button may be a physical button that you press and hold while igniting the pilot, or it may be a knob that you turn to the "Pilot" position to initiate the ignition process.
7. Light the Pilot Light:
* If you have a physical pilot button, press and hold it down while using a long lighter or a fireplace match to ignite the pilot burner. Continue holding down the button for about 30 seconds to allow the pilot flame to stabilize.
* If you have a knob, turn it to the "Pilot" position and depress it as you use a long lighter or match to ignite the pilot burner. Continue holding the knob down for approximately 30 seconds.
8. Release the Pilot Button or Knob: After the pilot flame remains lit for about 30 seconds, release the pilot button or knob slowly. The pilot light should continue to burn.
9. Set the Gas Control Valve: Turn the gas control valve knob to the "On" position to allow the main burner to operate. Adjust the temperature setting as needed.
10. Replace the Access Door: If you removed an access door, close it securely and reattach any screws you removed to secure the door in place.
11. Monitor the Water Heater: Keep an eye on the water heater to ensure it operates correctly. The pilot light should remain lit, and the main burner should ignite when hot water is needed.

It's important to consult your specific A.O. Smith water heater's user manual or documentation for precise instructions and safety guidelines. Additionally, always follow safety precautions when working with gas appliances, including checking for gas leaks using a gas leak detection solution or soapy water after any maintenance or repair work. If you encounter any issues or are uncertain about any step in the process, consider seeking professional assistance to ensure the safe operation of your gas water heater.
