How to Light a Ao Smith Water Heater: Step-by-Step Guide

To light an AO Smith Water Heater, locate the pilot light assembly and turn the gas control valve to the “Pilot” position, then use a long fireplace match or a BBQ lighter to ignite the pilot light. When it comes to lighting an AO Smith Water Heater, a few simple steps are all that’s needed to ensure a reliable and efficient heating process.

By following these instructions, you can safely and easily light your water heater. So, let’s get started!

Safety Precautions

When dealing with gas-powered appliances, it is crucial to prioritize safety measures. Failing to adhere to proper safety precautions can lead to hazardous situations. Before attempting to light your Ao Smith water heater, it is important to understand and implement the following safety measures.

Understanding Gas Leaks

Gas leaks are a serious safety concern when dealing with a gas-powered water heater. It is crucial to be vigilant and able to identify the signs of a potential gas leak. Any suspicion of a gas leak should be addressed immediately to prevent any risks of fire or health hazards.

Ventilation Requirements

Proper ventilation is essential for a gas-powered water heater to operate safely and efficiently. Inadequate ventilation can lead to the build-up of dangerous gases, such as carbon monoxide. Ensure that the area surrounding the water heater is well-ventilated to prevent the accumulation of harmful gases.

Gathering Necessary Tools

Before lighting your AO Smith water heater, make sure you have the necessary tools at your disposal.

Quality Flashlight

Ensure you have a durable flashlight with fresh batteries as the pilot light area can be dark.

Long-handled Lighter

Use a long-handled lighter to safely reach the pilot light without risking burns.

Locating The Pilot Light

When it comes to lighting an AO Smith water heater, finding the pilot light is the first step. The pilot light is the small flame that ignites the burner, allowing the water heater to heat up the water. Without a properly functioning pilot light, the water heater cannot produce hot water.

Identifying The Control Knob

To locate the pilot light, you need to first identify the control knob. The control knob is typically located near the bottom of the water heater, either on the front or side. It is a small cylindrical knob that allows you to adjust the temperature of the water heater. Look for the knob with temperature markings or icons indicating “Pilot” or “Off”.

Accessing The Burner Chamber

Once you have located the control knob, accessing the burner chamber is the next step. The burner chamber is the area where the pilot light and main burner are located. To access it, you may need to remove a metal cover or panel. Refer to the water heater’s manual or instructions on how to properly access the burner chamber.

If you are unsure about the location or accessibility of the burner chamber, it is always recommended to consult a professional or the manufacturer’s customer service for assistance and guidance.

Preparing For Lighting

To properly light an Ao Smith water heater, ensure the gas valve is set to “pilot. ” Hold the control knob down while using a long lighter to ignite the pilot flame. Once lit, release the knob and adjust the temperature setting accordingly.

Turning Off The Gas

First, locate the gas supply valve and turn it off by rotating it clockwise.

Make sure the handle is perpendicular to the pipe to ensure the gas supply is completely shut off.

Waiting For Gas To Dissipate

After turning off the gas, wait for at least 5-10 minutes for any residual gas to dissipate.

This helps to reduce the risk of a fire or explosion when lighting the water heater.

Lighting The Pilot Light

When it comes to lighting a pilot light, it’s important to follow the right steps to ensure proper functioning and safety of your AO Smith water heater. In this section, we will guide you through the process of lighting the pilot light with clear instructions and visual aids.

Turning The Control Knob To Pilot

The first step in lighting the pilot light is to locate the control knob on your AO Smith water heater. The control knob is usually located near the bottom of the heater, close to the gas supply line. It’s important to ensure that the gas supply valve is fully open before proceeding.

Once you’ve located the control knob, you need to turn it to the “pilot” position. This position is typically marked with the word “pilot” or a small flame symbol. To turn the knob, simply grip it firmly and rotate it counter-clockwise until it aligns with the pilot position.

Using The Long-handled Lighter

Now that the control knob is in the pilot position, it’s time to light the pilot light itself. This is where a long-handled lighter comes in handy. A long-handled lighter allows you to reach the pilot light without having to get too close to the open flame.

Hold the lighter in one hand, ensuring that your fingers are well clear of the flame. With your other hand, reach into the pilot light area and position the lighter near the pilot burner. It’s important to keep steady pressure on the control knob while lighting the pilot light.

Once you are in position, press the control knob down and simultaneously press the ignition button on the lighter. This will create a spark that ignites the pilot light. Keep the control knob depressed for about 60 seconds to allow the thermocouple to heat up and establish a stable flame.

After 60 seconds, release the control knob and observe the pilot light. It should be a steady, blue flame. If the flame is weak or goes out, you may need to repeat the process, ensuring that you are holding the control knob down long enough for the thermocouple to heat up.

Now that you’ve successfully lit the pilot light, you can proceed to turn the control knob from the pilot position to the “on” position. This will allow the main burner to ignite and provide hot water to your home as needed.

Verifying Successful Ignition

Verifying successful ignition is crucial to ensure that your AO Smith water heater is operating efficiently and safely. After lighting the pilot light, it’s important to confirm that the ignition process was successful. This involves observing the pilot light and checking for proper burner operation.

Observing The Pilot Light

After igniting the pilot light, take a moment to visually inspect it. The pilot light should be a steady, blue flame. If the flame appears yellow or flickering, it may indicate an issue with the gas supply or combustion. A steady, blue flame indicates that the pilot light has been successfully ignited and is functioning properly.

Checking For Proper Burner Operation

Once the pilot light is confirmed to be burning steadily, the next step is to ensure that the burner is operating as it should. This can be done by observing the main burner when the water heater is actively heating water. The burner flame should also be a steady, blue flame. If it appears yellow or inconsistent, there may be an issue with the burner assembly or gas supply that requires attention.

Final Checks And Restarting The Heater

Before we conclude, let’s go over some final checks and the process for restarting your AO Smith water heater.

Setting The Temperature

To ensure efficient and safe operation, setting the temperature of your AO Smith water heater is crucial. Locate the temperature control dial on the unit and adjust it to your desired setting. For most households, a temperature between 120°F and 140°F is recommended for optimal energy efficiency and comfort.

Checking For Consistent Heat

After setting the temperature, turn on a hot water faucet to verify a consistent flow of heated water. Allow the water to run for a few minutes to ensure that the heater is functioning properly and delivering a steady stream of hot water.

If you notice any issues with the temperature or flow, refer to the troubleshooting section in your AO Smith water heater manual for guidance on resolving common problems.

Restarting The Heater

1. Once the temperature and heat consistency checks are completed, locate the power source for your water heater and switch it back on.
2. Wait for the water heater to reignite. You might hear a clicking sound as the igniter sparks to reignite the burner. This process may take a minute or two, so be patient.
3. Confirm that the water heater has restarted successfully by testing the hot water flow from a faucet. If hot water is flowing consistently, the heater has been successfully restarted.

Following these steps for setting the temperature, checking for consistent heat, and restarting your AO Smith water heater will ensure that your system is running efficiently and providing a reliable supply of hot water for your home.
