Understanding Pilot Lights
When it comes to gas heaters, understanding pilot lights is essential. A pilot light is a small flame that is constantly burning on a gas appliance, such as a heater. It serves as an ignition source for the main burner, allowing the appliance to produce heat.
Pilot lights are typically found in older gas heaters, while newer models may use electronic ignition systems.
What is a Pilot Light?
A pilot light is a small gas flame that is always burning. It is usually located near the burner assembly and is responsible for igniting the main burner when heat is needed. The pilot light is a crucial component of a gas heater, as it ensures that the appliance can produce heat efficiently.
Without a functioning pilot light, the heater will not be able to provide warmth.
Why Pilot Lights Go Out
There are several reasons why pilot lights may go out. One common reason is a draft in the area where the heater is installed. If there is a sudden gust of wind or a drafty environment, it can extinguish the pilot light.
Another reason could be a faulty thermocouple, which is a safety device that detects whether the pilot light is lit. If the thermocouple is malfunctioning, it may shut off the gas supply to the pilot light, causing it to go out.
It’s also possible for the pilot light to go out due to a lack of gas supply or a clogged pilot tube. In some cases, the pilot light may simply need to be relit. However, if the pilot light continues to go out repeatedly, it is best to consult a professional technician to diagnose and fix the underlying issue.
When to Relight Your Pilot
If you notice that your gas heater is not producing heat, it is possible that the pilot light has gone out. In this case, you will need to relight the pilot light. However, before attempting to relight the pilot light, it is important to turn off the gas supply to the heater and wait for any lingering gas to dissipate.
This is a safety precaution to prevent any potential accidents.
Once you have ensured that the gas supply is turned off, you can follow the manufacturer’s instructions for relighting the pilot light. This typically involves holding down a button or turning a knob to allow gas to flow to the pilot light, while using a long lighter or match to ignite the flame.
After successfully relighting the pilot light, you can turn the gas supply back on and test the heater to ensure it is functioning properly.
Remember, if you are unsure about how to relight the pilot light or if the pilot light continues to go out frequently, it is best to seek professional assistance. A qualified technician will be able to diagnose and resolve any issues with your gas heater, ensuring it operates safely and efficiently.
Safety Precautions
Turn Off the Gas
Before attempting to light a pilot light on a gas heater, it is crucial to turn off the gas supply. This can typically be done by locating the gas shut-off valve near the heater and turning it to the “off” position.

Check for Leaks
Prior to lighting the pilot light, it is important to check for any gas leaks. One way to do this is by using a mixture of soap and water. Apply the soapy solution to the gas connections and observe for any bubbles. If bubbles form, it indicates a gas leak.
In such cases, it is best to refrain from attempting to light the pilot light and instead contact a professional to resolve the issue. Gas leaks can be dangerous and should be addressed immediately.
Have Proper Equipment Ready
When preparing to light a pilot light on a gas heater, it is essential to have the proper equipment ready. This includes a long-reach lighter or a matchstick, as well as a flashlight for better visibility if the pilot light is located in a dimly lit area.
It is also wise to have a fire extinguisher nearby as a precautionary measure. Having the necessary equipment on hand ensures a smoother and safer process.
Remember, safety should always be the top priority when dealing with gas heaters. If you are unsure about any step or encounter any difficulties, it is best to consult a professional to avoid any potential hazards.
Relighting the Pilot Step-by-Step
Remove Any Debris
Before attempting to relight the pilot light on your gas heater, it is important to ensure that there is no debris blocking the pilot tube. Use a small brush or a can of compressed air to gently remove any dirt, dust, or other debris that may have accumulated.
This will help to ensure a clean and unobstructed pathway for the gas to flow.
Light the Match/Lighter
Once the pilot tube is clear, it’s time to prepare to light the pilot light. Grab a long match or a fireplace lighter and hold it near the pilot assembly. Keep your face away from the opening to avoid any accidental contact with the gas.
Depress the Pilot Valve
Next, locate the pilot valve on your gas heater. It is usually a small red or black button located near the pilot tube. Depress the pilot valve and hold it down while you proceed to the next step.
Hold Valve Down 60 Seconds
While holding down the pilot valve, carefully light the match or ignite the lighter. Gently bring the flame close to the pilot tube opening. Once the flame is near the opening, you should see the pilot light ignite.
Continue to hold down the pilot valve for about 60 seconds to allow the thermocouple to heat up and keep the gas flowing.
Turn Gas Back On and Test
After the recommended 60 seconds, release the pilot valve and turn the gas supply back on. You can do this by turning the gas control knob to the “on” position. If the pilot light remains lit, you have successfully relit the pilot light on your gas heater.
However, if the pilot light goes out after releasing the pilot valve, it may indicate a problem with the thermocouple or another issue that requires professional assistance.
Always remember to prioritize safety when dealing with gas appliances. If you are unsure or uncomfortable with relighting the pilot light on your gas heater, it is best to contact a licensed professional to handle the task.
