Safety Precautions
When relighting a gas water heater, safety is the top priority. It's essential to take specific steps to avoid dangers like gas leaks or burns. Follow these guidelines to protect yourself and your home.
Turn Off the Gas Supply
Before doing anything, locate the main gas valve near the water heater and turn it to the "off" position. This stops gas flow to the heater, reducing the risk of leaks or accidents. Use a crescent wrench if needed for tight fittings. It's important to wait a few minutes to ensure any residual gas dissipates. Blocking drafts by sealing windows or doors is another important step.
Allow the Heater to Cool
The gas water heater can be extremely hot. After turning off the gas, give the heater time to cool down. Touch the outer surface lightly to test its temperature. If it feels too warm, wait until it cools more. This prevents burns and protects your safety. Keep kids and pets away from the area to avoid accidental contact.
Check for Gas Leaks
Using your nose, check for a rotten egg smell, which indicates a gas leak. Another option is to use a soap-water solution to brush on connections; bubbles suggest a leak. If you find any leaks, do not attempt to light the pilot or use electrical equipment. This is the time to call professionals to handle repairs safely.
Understanding Your Gas Water Heater
Gas water heaters are essential for providing hot water in homes. Familiarizing yourself with their components and ignition systems can help you maintain and troubleshoot issues when needed.
Components and Functions
A gas water heater consists of several key parts. The tank stores the water and is insulated to retain heat. The gas control valve regulates gas flow to the burner. The thermocouple acts as a safety device, ensuring that gas flow stops when the pilot light is off.
The burner is located beneath the tank and heats the water. An exhaust flue directs combustion gases out of the home. Understanding these components can help you operate and maintain your heater effectively.
Pilot Light vs. Electronic Ignition
Gas water heaters use two main ignition systems: pilot lights and electronic ignitions. A pilot light is a small flame that burns continuously. When the water in the tank requires heating, the burner uses this flame to ignite the gas. Problems can arise if the pilot light goes out, requiring relighting.
An electronic ignition system does not have a continuously burning flame. Instead, it ignites the gas heater only when needed, using a small electric spark. This system can be more efficient as it uses less gas over time.

Preparation for Relighting
Starting with the correct setup is crucial before you relight your gas water heater. Make sure to find the instruction label on your unit and gather all the necessary tools for the job. This will help ensure safety and efficiency throughout the process.
Locate the Instructions Label
Find the instructions label on your water heater. This label is often located on the side of the unit or near the gas control valve. It provides essential details specific to your heater model. These instructions can include information about how to turn off the gas, which is vital for safe relighting.
Having this information helps you follow the correct steps and avoid any model-specific problems. If you can't locate the label, check the manufacturer's website for a digital manual.
Gather Necessary Tools
Assemble the tools you will need for relighting. Typical tools include a lighter or long match if your model requires manual lighting, a flashlight for better visibility, and possibly a screwdriver to remove an access panel. Ensure you have any additional items mentioned in your heater’s instruction label.
Knowing what tools are needed ahead of time saves you from delays and makes the process smoother.
Relighting Procedures
Relighting a gas water heater varies depending on the type of ignition system. Whether dealing with standing pilot models or electronic ignition models, understanding the correct steps is crucial for safety and efficiency.
For Standing Pilot Models
To relight a standing pilot model, start by locating the gas control valve. Turn it to the "off" position and wait about 10 minutes for any residual gas to dissipate. This step is important because gas is highly flammable.
Afterward, turn the control to the "pilot" setting. Press and hold down the pilot button, then use a lighter to ignite the pilot flame. If you can't reach the pilot, use a long-reach lighter. Keep holding the button for about 30-60 seconds to ensure the pilot light stays lit.
Release the button gently. If the flame remains steady, turn the control to the "on" position. Adjust the thermostat to your desired setting. If the pilot doesn’t stay lit, the thermocouple might need replacement.
For Electronic Ignition Models
For electronic ignition models, begin by turning off the gas control valve. Wait 10 minutes for safety, allowing any built-up gas to clear. These models typically have a reset button or switch that you press to restart the ignition process.
Locate this button and press it firmly. You may hear a clicking sound as the ignition process begins. Watch to ensure the burner ignites properly and continues burning.
If the ignition fails, verify that the gas supply is uninterrupted. If issues persist, consult experts.
Post-Relighting Checks
Once you have relit the pilot light on your gas water heater, it is crucial to ensure everything is functioning as it should be. This involves checking the pilot flame for stability and observing for any irregularities that might indicate a problem.
Verifying the Flame
Start by observing the pilot flame. A strong, steady blue flame is your goal, as it indicates proper combustion. If the flame is yellow or flickers, there might be an issue with fuel or air supply.
Check that the flame fully envelops the thermocouple tip. This ensures it will heat well and keep the gas valve open. If the flame is too low or weak, the gas valve may close, extinguishing the flame. Consider adjusting the flame or consulting a professional to correct issues.
Safety Note: Keep your head and hands clear of the burner area when checking. This helps prevent any accidents or burns if the flame is erratic. If you're unsure of what to do, contact us. We have HVAC and plumbing experts who can safely handle such issues.
Monitoring for Irregularities
After relighting, monitor the heater for unusual sounds or smells. Listen for popping or hissing sounds and watch for any gas smell, which may indicate a leak. These can be signs of combustion issues or other malfunctions.
Check the temperature settings and ensure they match your desired levels. Look at the pipes for any water leaks, which can point to pressure problems. Maintain regular checks to catch these issues early and prevent damage.
Be sure your home’s CO detectors are functioning. This provides an extra layer of safety by alerting you to potential leaks.
Troubleshooting Common Issues
Relighting a gas water heater can run into a few obstacles. Understanding these challenges can help you address them quickly and safely, ensuring your water heater functions properly.
Pilot Won't Light
If the pilot won't light, start by checking the gas supply. Ensure the gas valve is in the "on" position. Sometimes, air can get trapped in the gas line. In this case, turn the gas valve off, wait a few minutes, then try relighting the pilot. If it still doesn't light, look for any residual gas by letting the unit sit for about five minutes. This waiting period allows any leftover gas to disperse safely.
Another common issue is a dirty pilot opening. Dirt or debris can block the flow of gas, preventing the pilot from igniting. Clean the pilot light opening with a needle to remove any obstructions. If these steps don't solve the problem, it's best to consult professionals.
Pilot Won't Stay Lit
If the pilot light keeps going out, it might be due to a faulty thermocouple. This safety device detects the presence of the pilot light and shuts off the gas if it doesn't sense a flame. Check if it's securely connected and properly aligned with the flame. Sometimes, the thermocouple may simply need cleaning with light sandpaper to remove any buildup.
Drafts can also extinguish the pilot light. Check if there are any air drafts near your water heater and eliminate them if possible. If the problem persists, replacing the thermocouple may be necessary.
Burner Issues
If the burner isn't working properly, first inspect the color of the pilot flame. A healthy pilot flame is blue with a slight yellow tip. If it's predominantly yellow or flickering, adjust the pilot tube or clean it to stabilize the flame. Next, ensure the burner is free of dust and debris by cleaning it carefully with a brush and vacuum.
Additionally, the gas pressure might be too low. You can contact your utility company to verify gas supply issues. If these elements do not resolve your burner issues, consider scheduling an inspection with professionals.
