Introduction
An Imperial gas oven may use a small standing pilot flame, a piezo igniter, or an automatic electric ignition system. Knowing which type your appliance uses prevents you from turning a control incorrectly or expecting the oven burner to light when you only need the pilot. This guide explains how to light pilot on Imperial oven models, how to verify ignition, and what to do when the flame will not stay on.
Because Imperial ranges and ovens have different control arrangements, the model’s manual and the label on the appliance remain the final authority. If the instructions below differ from your appliance, follow the manufacturer’s directions and contact an experienced gas technician when uncertain.

How an Imperial Oven Works Pilot Works
A pilot flame is a small, continuously burning flame. Its purpose is to provide an immediate ignition source for the oven burner. When you turn an oven control to a heating position, the gas valve opens and the larger oven burner should ignite from the pilot flame.
The pilot itself consumes less gas than the oven burner and may remain lit after cooking. Some Imperial ovens have a separate pilot control or a pilot adjustment screw. Others are lit by a push button, piezo igniter, or repeated spark produced by a thermostat-controlled igniter.
The pilot flame and oven burner are different. Lighting the pilot does not mean the oven burner is on.
When the pilot is operating correctly, you should normally see a small flame near the oven burner. If the flame is absent, unstable, unusually large, or repeatedly extinguished, turn the oven control to the off position before investigating further.
Identify Your Ignition System
Before attempting ignition, identify the controls inside the oven. Look for a thermostat or selector knob, an oven control dial, a red or black push button, a small pilot adjustment screw, a piezo igniter, or a label explaining the ignition sequence.
Common configurations include:
- Standing pilot: The flame should remain lit continuously and is sometimes positioned beneath the oven floor.
- Push-button ignition: You press a surface or gas valve control to release gas and create a spark or ignition area.
- Piezo ignition: Repeated pressing produces a series of sparks near a pilot or burner.
- Automatic spark ignition: Turning the oven control to a heating position activates the thermostat, which attempts to light the oven burner several times.
Do not repeatedly press a button or rotate a gas control beyond its marked range. Excessive attempts can fill the oven with unburned gas. If your Imperial oven uses a sequence not described here, consult the model’s documentation before proceeding.
Prepare the Oven Safely
Begin by reading the ignition label on the oven and identifying the correct control. The control must be in the off position. If the oven is still hot, allow it to cool long enough to avoid burns.
Open the oven door and lower broiler compartment door if the model has one. Some manuals require the lower door to remain open while lighting. Remove racks only if necessary, and do not move or spill flammable materials around the appliance.
Before operating the controls, make sure you do not smell natural gas. Do not operate switches, touch electrical connections, or create a spark if gas odor is present. Leave the area, avoid open flames, and contact the gas utility or a qualified professional from a safe location.
Keep towels, packaging, plastic, and grease away from the pilot and burner. The area around the burner should be dry and clear. If the pilot is beneath a removable oven floor, open the compartment exactly as directed by the manual rather than lifting or shifting parts that could damage the appliance.
Step-by-Step Lighting Guide
The following sequence is intended for an Imperial oven with an accessible pilot and a control or igniter specifically designed for manual lighting. If the appliance label gives different directions, use the label’s sequence.
- Confirm that the oven is off. Turn the oven control to off. If the control has an off mark, make sure the indicator aligns with it. Do not turn it to a baking or broiling position during this preparation.
- Open the necessary doors. Open the oven door and, when required by the appliance instructions, the lower compartment containing the pilot. This gives you access to the flame and provides ventilation.
- Locate the pilot and ignition source. Look for the pilot opening and the ignition button, piezo release, or approved flame-ignition point. Never direct a flame at an arbitrary part of the oven.
- Prepare the pilot for gas. If the Imperial oven has a surface or oven gas valve that must be pressed and turned to a lighting position, push it in and turn it only to the marked lighting setting. Hold it there briefly, as specified on the control. Do not force it or move it beyond the marked position.
- Create the ignition. Press the ignition button or operate the piezo igniter as directed. If the manufacturer specifically allows ignition with a long-handled lighter or a small flame, use it only at the designated pilot opening. Keep your hand and flame away from the larger burner and metal surfaces.
- Observe the flame immediately. When gas reaches the pilot, a small flame should appear. Some systems create a brief flash before settling into a steady flame. Continue holding the control only for the period given in the manual, usually a few seconds.
- Release the control slowly. Carefully release the pushed control or stop operating the igniter. A stable flame indicates that the pilot or thermocouple is holding the gas open. If the flame shuts off when you release the control, continue troubleshooting rather than repeatedly cycling the valve.
- Close the access doors. Once the flame remains stable, return the oven control to off and close any lower compartment door required for normal operation. Keep the oven door open until the required temperature has been reached.
Some ovens use the oven thermostat to ignite the burner rather than requiring a separate manual pilot. In that design, you should not try to ignite the standing pilot independently unless the appliance includes a specific pilot control.
Using Automatic or Piezo Ignition
On a model with automatic ignition, the oven control is also the ignition control. Turn it from off to the desired heating position, such as bake. A thermostat will open the burner gas valve and repeatedly attempt ignition. The oven may click, tick, or hum while it tries to ignite the burner.
Do not stand directly in front of the door when operating a spark igniter. After a successful ignition, the burner should produce a steady flame with a blue base and faint yellow tips. If several ignition attempts occur without lighting, turn the control back to off, allow the oven to cool, and inspect the pilot area only when it is safe to do so.
A piezo system may require you to press and release the igniter button repeatedly while gas flows to the pilot. On some controls, the button must remain depressed for the full time printed on the knob. Use several firm releases rather than holding or twisting the control beyond its intended travel.
Automatic ignition does not eliminate the need for a sound pilot flame. If the standing pilot is too small or cannot stay lit, the thermostat may click repeatedly but fail to ignite the oven burner. In that case, the underlying pilot problem must be corrected first.
Verify a Successful Pilot Flame
A correctly lit pilot should be small, steady, and stable. View it through the designated opening without opening panels or removing parts not intended for user access. A healthy flame is usually blue, although slight yellowing at the tip can occur with properly adjusted combustion air.
Check the following points:
- The flame remains on rather than cycling on and off.
- It is directed at the correct ignition area beside the oven burner.
- It is neither extremely large nor completely separated from the burner.
- It stays lit after the ignition control is released.
- You do not notice a persistent odor of unburned gas.
If the pilot is yellow, wobbly, or blowing away from the burner, stop using the oven until the issue has been corrected. A flame that lifts into a tall plume can indicate an air-mixing or burner problem. Do not attempt to adjust internal burner parts unless your appliance instructions specifically authorize it and you have the required technical knowledge.
For electric spark systems, also verify that the oven burner—not only the pilot—ignites when you select a temperature. The standing pilot may remain lit while the larger burner fails, leaving the appliance operating without the intended heat source.
Using the Oven After Lighting
After confirming stable ignition, turn the thermostat to the required temperature. If the oven has a temperature dial, set it in the normal manner rather than leaving it at the lighting position. Wait through the normal preheating cycle before placing food inside.
Keep the oven door closed during cooking unless the manufacturer recommends otherwise. Avoid repeatedly opening the door while the system is trying to ignite because changing air movement can prevent ignition or cool the thermocouple.
If you notice a strong gas odor, an unstable burner flame, repeated clicking without ignition, or a burner that continues running after the control is off, turn the oven control to off and stop using the appliance. Ventilate the room without operating electrical switches, then arrange professional assistance.
Pilot Flame and Ignition Comparison
Observing the oven’s behavior helps distinguish a normal ignition sequence from a fault.
| What You Notice | Likely Meaning | Recommended Action |
|---|---|---|
| Small steady blue pilot | The standing pilot is likely operating correctly. | Check that the oven burner also ignites when heat is selected. |
| Repeated clicking without flame | The thermostat is attempting ignition, but the pilot may be absent or gas is not reaching the burner. | Stop the cycle and follow the troubleshooting checks. |
| Brief flash followed by steady flame | Normal spark or manual ignition may have occurred. | Release the control and confirm the flame remains stable. |
| Flame shuts off when control is released | The thermocouple, flame sensor, or valve may not be holding gas. | Turn the control off and request qualified service. |
| Pilot is tall or yellow | Combustion air, burner condition, or flame alignment may be incorrect. | Stop using the oven and arrange service. |
| Pilot stays lit, but oven burner does not | Ignition gas, the burner, or the oven thermostat may be faulty. | Do not continue cooking; arrange diagnosis. |
| Persistent gas odor | There may be an incomplete connection or a combustion problem. | Stop use, ventilate safely, and contact the gas utility or a technician. |
Troubleshooting a Pilot That Will Not Light
Begin troubleshooting only after the oven control is off and the appliance is cool enough to inspect safely. Work through one step at a time rather than repeatedly cycling the ignition system.
No Gas Reaches the Pilot
If pressing the valve or selecting a heating position does not produce a flame, the supply may not be reaching the pilot. A closed supply valve, an incorrect control position, or an empty supply line can be responsible. Confirm that the appropriate gas supply is open and that the oven control is held in the specified lighting position. Do not remove the burner or gas valve to investigate.
The Igniter Does Not Spark
If pressing a piezo button produces no spark, moisture, debris, or a worn igniter may be interfering. A loose or failed spark electrode can also stop ignition. Clean only the accessible area as directed in the manual. If the electrode is loose, coated, cracked, or no longer produces a consistent spark, have it replaced by a technician.
The Pilot Lights but Does Not Stay Lit
If the flame appears only while the control is held, the safety thermocouple or flame-sensing system may be defective. It may also be affected by a dirty pilot or an unstable air current. Clean debris only from locations approved for user access. Do not bridge, bypass, or remove the safety sensor.
The Pilot Flame Is Absent but the Igniter Clicks
A clicking thermostat usually indicates that the control is requesting ignition. The burner may fail to light when the pilot is out or positioned incorrectly. Turn the control off and inspect only the visible burner area. If nothing is visibly obstructing the pilot, the problem may involve the igniter, gas valve, moisture, or a clogged burner opening.
The Oven Clicks Repeatedly
Repeated clicking without ignition can allow gas to accumulate inside the oven. Stop the cycle and leave the appliance off. Check whether the door was open during ignition, whether the control was moved too quickly from off to heat, and whether the oven contains grease buildup or packaging that needs removal. Persistent clicking after these checks requires service.
The Pilot Keeps Going Out
Strong kitchen air currents, a cool room, or an improperly adjusted pilot can make a small flame unstable. Avoid operating the oven near an open window, fan, fireplace, or other strong draft. Do not enlarge the flame by turning an internal adjustment screw unless the model manual gives a specific procedure. A pilot that repeatedly goes out usually needs inspection rather than repeated relighting.
Common Mistakes to Avoid
One common mistake is operating the oven before understanding its ignition sequence. Another is assuming that the pilot and burner are the same. A lit pilot does not guarantee that the oven burner is receiving gas.
- Do not use a paper match or ordinary handheld lighter where the manual requires a long igniter or electric spark.
- Do not light a pilot from beneath a cutaway, damaged panel, or unauthorized opening.
- Do not force a stiff thermostat or gas valve; resistance may indicate a mechanical fault.
- Do not leave the control in a lighting position after the flame is stable.
- Do not ignore repeated clicking, a drifting flame, or a gas odor.
- Do not disassemble the thermostat, gas valve, thermocouple, or burner.
Avoid allowing grease or spilled food to accumulate around the pilot. Debris can block the flame, obstruct airflow, interfere with a thermocouple, and create a fire or carbon-monoxide risk.
Tips and Best Practices
- Keep the appliance guide available. Imperial control layouts can change between models, even when the overall appearance is similar.
- Read the ignition label. Labels provide the correct hold time, ignition position, and release sequence.
- Use the designated ignition point. This directs the spark or flame toward the pilot rather than allowing gas to collect.
- Maintain ventilation. Use the range hood or adequate ventilation as recommended for gas cooking.
- Keep the pilot area clean. Remove grease and crumbs only from user-accessible portions and only when the oven is off and cool.
- Watch the flame. Report a flame that changes color, grows unusually large, or repeatedly extinguishes.
- Do not leave ignition attempts unattended. Stay nearby until stable flame and burner operation are confirmed.
- Use professional service for persistent faults. Gas valves, thermocouples, electrodes, and burners should be adjusted or replaced by qualified personnel.
Install a working smoke and carbon-monoxide alarm according to local guidance. These alarms are supplemental safety tools and do not replace correct ignition, ventilation, or appliance maintenance.
Schedule service when a pilot repeatedly needs relighting, the burner is difficult to ignite, the flame is unstable, or gas valves become stiff. Early attention can prevent a small pilot issue from becoming an unsafe burner or valve problem.
Frequently Asked Questions
How do I light a pilot on an Imperial oven if I do not know the model?
First identify whether the oven uses a standing pilot, push-button ignition, piezo igniter, or thermostat-controlled spark. Examine the control markings and appliance label without removing covers. Because the correct press-and-hold sequence depends on the model, avoid forcing the control or borrowing a sequence for a different Imperial oven. Obtain the model number or provide oven dimensions and control photos to the manufacturer or a qualified appliance technician.
Why is there no pilot flame under my Imperial oven?
A missing pilot flame may result from an accidentally closed gas supply, an incorrect lighting sequence, a failed igniter, a clogged pilot opening, or a gas-valve problem. Confirm that the oven is off before inspection. If the manual-authorized ignition sequence produces no flame, stop attempting ignition and arrange service.
Why does the pilot flame turn off when I release the button?
The system may include a thermocouple or flame sensor that must remain heated to keep the gas valve open. A dirty pilot, weak flame, damaged sensor, or defective valve can interrupt the process. Repeatedly holding or pressing the button is not a safe repair. Turn the control off and have the system inspected.
Should the pilot stay on after my Imperial oven finishes cooking?
On a standing-pilot model, the pilot commonly remains lit after cooking to make the next ignition easier. On a fully automatic model, the design may differ. The appliance label or manual will indicate whether a continuous pilot is intended. If no flame is visible when the model should have one, stop using the oven.
What color should an Imperial oven pilot flame be?
A correctly adjusted pilot is usually blue or blue with faint yellow tips. A flame that is consistently yellow, orange, very tall, or blowing sideways should be inspected. Do not continue cooking with a visibly abnormal flame because incomplete combustion can create hazardous fumes.
Can I light the pilot with a match or lighter?
Only use a flame when the manufacturer explicitly permits it and the appliance has a designated ignition opening. Some models require a piezo button or automatic spark and should not be manually exposed to a flame. Use a suitable long-handled ignition tool, keep other materials away, and never apply an open flame to an arbitrary burner location.
Do I need to open the broiler compartment?
On some Imperial ranges, the standing pilot is located in a lower compartment and can only be accessed through the broiler door. On other models, the pilot is visible through the oven door or a dedicated opening. Follow the appliance instructions; do not dismantle the oven to reach the pilot.
Why does the oven click several times but never light?
The thermostat is likely attempting to ignite the oven burner. Ignition may fail when the standing pilot is absent, the pilot is too small, the burner opening is blocked, or a gas component is defective. Turn the control off after repeated unsuccessful attempts, ventilate the area, and allow sufficient time for any accumulated gas to clear before investigating under the manual’s safety directions.
What should I do if I smell gas while lighting the oven?
Do not ignite a flame, press an electrical switch, or continue operating the appliance. Turn the oven control off if it is safe to do so, ventilate the area with open doors or windows, leave the room, and contact the gas utility or a qualified emergency professional from a safe location. If the odor is strong or immediate, call emergency services.
When should I call a technician instead of relighting the pilot?
Call for service when a properly positioned pilot will not light, the flame cannot remain lit, the valve or thermostat is stiff, the oven repeatedly clicks, the burner does not ignite, or any part is damaged or loose. A gas technician can safely test gas pressure, valves, thermocouples, electrodes, and burner openings without creating an uncontrolled ignition or fire risk.
Conclusion
To light pilot on Imperial oven equipment successfully, identify the ignition system, turn the control off, open the required access door, and follow the manufacturer’s marked ignition sequence. Hold the control only for the specified time, then confirm that the pilot remains steady before operating the oven.
A blue pilot should remain stable, but the oven burner must also ignite when you select heat. Treat repeated clicking, an extinguished pilot, an abnormal flame, or a persistent gas odor as reasons to stop using the oven. Knowing how to light pilot on Imperial oven models is useful, but forcing controls or bypassing safety devices is not a substitute for professional gas-appliance service.
