What You'll Learn
Pilot lights are common in commercial gas cooking equipment
Electric ovens do not have pilot lights. Modern ovens, including electric ones, use piezo-electric ignitors. These ignitors do not require a continuously burning flame, unlike the traditional pilot light system.
In a commercial kitchen, a pilot light ensures a steady temperature and a consistent cooking experience. It also saves time and is a safer alternative to manually lighting equipment, which can be cumbersome and dangerous. However, pilot lights can be a major drawback due to their high gas consumption, with some estimates placing it at 80% of the total gas volume burned by a piece of equipment.
Due to the drawbacks of standing pilot lights, manufacturers have developed alternatives such as electronic ignition systems, which only create a spark when the appliance is turned on, and battery spark ignition, which uses a battery to generate an electric spark. These modern systems have made it possible to shut off the gas completely when not in use, conserving energy.
Despite the availability of alternative ignition systems, pilot lights are still common in commercial kitchens. This is partly due to the convenience and reliability they offer, but also because certain insurance policies will not cover fire damage if the gas is left on overnight. Therefore, some restaurants opt to shut off the gas main and pilot lights at the end of the day, relighting them in the morning.

Older gas oven models often require manual ignition
Electric ovens do not have a pilot light, as they use piezo-electric ignitors. Therefore, to ignite the oven, one simply has to turn and press the knob, and after a few seconds, once the fire is lit, release the knob and adjust the temperature.
In contrast, older gas oven models often require manual ignition, which means that users have to turn a knob to start the gas flow and ignite the oven. These gas ovens rely on pilot lights for ignition, which are small, constantly burning flames that enable the oven to become operational as soon as the stove is turned on. This system was once prevalent in most gas stoves and ranges but has since been replaced by electronic ignition systems in modern ovens.
The traditional pilot light system in gas ovens has several drawbacks. Firstly, it results in continuous gas consumption as the small flame is always burning. This can be a safety concern, as there is a risk of gas leaks if the pilot light is not functioning correctly. Therefore, gas ovens with pilot lights require regular checks and maintenance to ensure safety.
However, some people still prefer the traditional pilot light system for its simplicity and immediate ignition. The continuous flame of the pilot light also ensures a steady temperature and consistent cooking experience, which is valued by culinary enthusiasts who prefer traditional cooking methods.
While electronic ignition systems have largely replaced pilot lights in modern gas ovens, some older models and traditional gas stoves may still require manual ignition using a pilot light.

Modern gas stoves have electronic ignition systems
Electric ovens do not have pilot lights. Older gas ovens used to have pilot lights, which were small, constantly burning flames that were essential for initiating the gas flow. However, with technological advancements, modern gas stoves have transitioned away from standing pilot lights to electronic ignition systems.
The introduction of electronic ignition systems marked a pivotal development in the design and functionality of gas stoves. These modern systems eliminated the need for pilot lights in most gas stoves and ovens. Instead of a constant flame, an electronic spark ignites the gas flow only when the appliance is turned on. This innovation not only enhances safety by reducing the risk of accidental gas leaks but also improves energy efficiency as gas is no longer wasted when the appliance is not in use.
There are different types of electronic ignition systems available in modern gas stoves. One common type is the piezo-electric ignitor, which requires the user to turn and press a knob to ignite the oven. After a few seconds, the fire is lit, and the knob can be released to adjust the temperature. Some modern gas stoves also use a spark igniter, which lights a gas pilot that heats a safety device, allowing the main burner to turn on. Another type of electronic ignition system is the glow bar ignition system, where an electrically heated element, known as a glow bar, gets hot enough to ignite the gas.
While electronic ignition systems have become widespread in modern gas ranges, not all gas stoves have abandoned pilot lights. Pilot lights are still essential in some traditional gas stove models, where they are valued for their simplicity and immediate ignition. In these stoves, maintenance and safety are paramount, requiring regular checks to ensure the pilot light is functioning correctly and that there are no gas leaks.
In summary, modern gas stoves have largely transitioned from standing pilot lights to electronic ignition systems, offering improved safety, energy efficiency, and convenience. However, some traditional gas stoves still maintain pilot lights for their simplicity and reliability. When selecting a gas stove, it is important to consider the advantages and disadvantages of both systems to ensure the appliance meets your specific needs and preferences.

Pilot lights can be reignited with a long butane lighter
Pilot lights are small gas flames, usually natural gas or liquefied petroleum gas, that burn continuously to ignite a larger burner. They are commonly found in traditional gas stoves and ovens, although modern gas stoves have transitioned to electronic ignition systems.
Pilot lights occasionally go out due to several reasons, such as a faulty thermocouple, clogged pilot orifices, poor appliance location, or simply a gust of wind. When this happens, you can reignite the pilot light using a long butane lighter. Here's how you can do it:
- Ensure you have the correct tools and read the manufacturer's instructions. You will need a flashlight and a long barbecue lighter or fireplace match for manual ignition.
- Remove the access panel that covers the pilot light access point. Depending on the model, you may need to snap it off or use a screwdriver to remove it.
- Turn the gas regulator valve to the "OFF" position and wait for a few minutes to allow any excess gas to dissipate.
- Turn the gas valve to "PILOT."
- Locate the small button labeled "RESET" near the valve.
- Press and hold the "RESET" button while simultaneously applying the flame of your long butane lighter to the pilot light valve. Hold the flame steady until the pilot ignites.
- Once the pilot light is ignited, gently release the "RESET" button and turn the gas valve knob to the "ON" position.
- Replace the access panel and turn on the furnace switch.
- If necessary, increase the thermostat's temperature setting to get the furnace to kick on.
It is important to note that you may need to repeat the procedure if the burners do not ignite immediately. This is because the thermocouple might not have heated up enough. In such cases, hold the reset button for forty-five to sixty seconds after lighting the pilot.
Additionally, always exercise caution when working with gas appliances. If you are uncomfortable or unsure about any part of the process, it is best to call a professional for assistance.
