The pilot light in a gas fireplace, often simply called the pilot, plays a crucial role in ensuring your fireplace ignites efficiently and safely. Our own model features a classic standing flame pilot rather than the more modern intermittent ignition systems commonly found in newer units. Although this article provides comprehensive insights into all types of gas fireplace pilot lights, including older and newer designs, the core principles remain consistent across models.
Is There a Pilot Light on a Gas Fireplace?
Typically, gas fireplaces are equipped with a pilot light, which acts as an essential component in the ignition process. The pilot’s main purpose is to help ignite the main burner flames quickly and reliably. For decades, the use of pilot lights has been a standard feature in gas fireplaces, appreciated for their simplicity and effectiveness.
What Exactly Is a Gas Fireplace Pilot Light?
A gas fireplace pilot light is a small, continuously burning flame that forms part of the ignition system. It serves as a starter flame that ignites the larger, visible flames when you turn on your fireplace. This tiny flame, often overlooked, is vital for safe and efficient operation. The pilot is typically paired with a spark ignitor or thermocouple, which provides the necessary spark or heat to keep the pilot flame burning. For example, in our fireplace, the pilot, thermocouple, and spark ignitor work together to ensure reliable ignition.
Do All Gas Fireplaces Have a Pilot Light?
Yes, virtually all gas fireplaces incorporate some form of pilot light or ignition system. The specific type—whether a traditional standing pilot or an electronic intermittent system—depends on the age and design of the unit. Older models generally feature a continuous flame, while newer models favor energy-efficient electronic ignitions that turn off when the fireplace is not in use.
Locating the Pilot Light on Your Gas Fireplace
The pilot light is usually positioned adjacent to the main burner, often beneath the faux media such as logs or coals. When inspecting your unit, look inside the firebox from above or check behind the control panel. In many models, the pilot is visible near the burner tray, which is typically located at the top of the burner assembly. For safety and ease of access, some fireplaces have an open panel at the base, revealing the pilot and ignition components. Always refer to your owner’s manual for precise location details, as designs vary widely.
Types of Gas Fireplace Pilot Lights
There are primarily two types of pilot lighting systems used in gas fireplaces:
- Traditional Standing Pilot
- Electronic Intermittent Pilot Ignition (IPI)
Standing Pilot Lights
These are the classic pilot lights that burn constantly, providing an immediate ignition source for the main burner. Their constant flame remains lit regardless of whether the fireplace is actively being used. While reliable, they tend to consume small amounts of gas continuously, which can add up over time. Most older gas fireplace models utilize this system, appreciated for its simplicity and minimal maintenance.
Intermittent Pilot Ignition
The IPI system employs modern electronic technology to ignite the main burner only when needed. The pilot light turns off automatically once the flames are extinguished, leading to greater energy efficiency. These systems require electrical power and often include a backup battery. They are common in newer models and significantly reduce gas consumption and operational costs over the long term.
Main Components of a Gas Fireplace Pilot Light
The ignition system varies by model but generally includes:
- Pilot: The small flame used to ignite the main burner.
- Thermocouple: A safety device that detects the pilot flame and shuts off gas if the flame goes out.
- Thermopile: Similar to a thermocouple but produces more power, used in some systems requiring higher current.
- Spark Ignitor: Produces a spark to ignite the pilot flame, often controlled electronically.
Our system, for example, combines a pilot, thermocouple, and spark ignitor, but does not include a thermopile. Always check your specific model’s components and manual for accurate details.
The Pilot Position on a Gas Fireplace
The pilot position is a setting on the control dial or switch that allows you to manually ignite or maintain the pilot flame. Usually, the control includes options such as ‘Off’, ‘Pilot’, and ‘On’. To light the pilot, turn the dial or press the button to the ‘Pilot’ setting, then use a spark or match to ignite the flame. Once lit, you can set the control to ‘On’ to keep the pilot active during operation. Always follow the manufacturer’s instructions for safe and proper lighting procedures.
Does the Pilot Light Stay Lit Constantly?
In traditional models, yes—the pilot light remains lit continuously, providing immediate ignition for the main burner. Modern systems with electronic ignition, however, turn the pilot off when the fireplace is not in use, saving energy and reducing gas consumption.
Is It Safe to Leave the Pilot Light On?
Leaving the pilot light on is generally safe and common in colder climates or during winter months when frequent use is expected. However, some manufacturers recommend turning it off during warmer months or if the fireplace will not be used for extended periods, to conserve gas and prevent unnecessary emissions. Always consult your owner’s manual for specific safety recommendations.
Can You Turn Off the Pilot Light When Not in Use?
Yes, especially with newer electronic ignition fireplaces, the pilot can be turned off to save energy. For traditional models, it can be turned off manually by switching the control to the ‘Off’ position and shutting off the gas supply, usually via a dedicated valve. Remember, relighting the pilot requires following safety procedures as outlined in your manual.
Steps to Turn On or Off the Pilot Light
To activate the pilot, set your control to the ‘Pilot’ position, then ignite the flame using a match or built-in ignitor. Once the pilot is steady, turn the control to ‘On’. To turn off, reverse the process: switch the control to ‘Off’ and close the gas supply if necessary. Always ensure proper ventilation and follow safety guidelines during this process.
Should the Pilot Be Left On During Summer?
Typically, it’s advisable to turn off the pilot in the warmer months when the fireplace isn’t in use, to reduce unnecessary gas consumption and prevent the room from becoming overly warm. However, in colder regions or for convenience, some choose to leave it on. Always follow manufacturer recommendations and safety practices.
What Happens if the Pilot Goes Out?
If the pilot light extinguishes, the thermocouple or thermopile detects the absence of heat and automatically shuts off the gas supply for safety reasons. Re-igniting the pilot usually involves following specific procedures—either manually relighting it or using an automatic ignition system, depending on your fireplace’s setup.
If the Pilot Is Off, Does the Gas Need to Be Turned Off?
Yes. Turning off the pilot typically involves shutting the gas supply using a dedicated valve to prevent any leaks or hazards. The safety mechanism of thermocouples or thermopiles prevents gas from escaping when the pilot is extinguished, but turning off the gas supply adds an extra layer of safety.
Gas Usage and Cost of Running the Pilot
The pilot light consumes a small amount of gas—much less than the main burner. In terms of expenses, maintaining a standing pilot can cost up to approximately $10 per month, depending on local gas rates and the efficiency of your fireplace. Electronic systems with intermittent ignitions eliminate this ongoing cost when not in use.
