Lighting a gas deep fryer correctly is essential for both safety and cooking performance. Whether you are using a commercial fryer in a restaurant kitchen or a smaller model at home, understanding how to ignite it properly prevents gas buildup, uneven heating, and ignition hazards.
Follow the steps below to safely light your Gas Fryer and keep it running efficiently.

1. Safety Comes First

Before touching the controls or gas valves:

• Read the manufacturer’s manual — different fryers have unique ignition systems.

• Make sure the fryer is off and the oil tank is clean and empty during ignition.

• Ensure the area is well-ventilated with no open flames nearby.

• Check for gas leaks using a soapy water solution on all connections — if bubbles appear, do not proceed until leaks are fixed.

Never try to light a fryer if you smell gas in the room. Turn off the main supply immediately and ventilate the area.

2. Identify the Type of Ignition System

There are two main types of gas deep fryers:

Manual Pilot Ignition

Requires lighting the pilot flame with a match or lighter.
This type is common in older or commercial fryers.

Automatic or Electronic Ignition

Uses a spark igniter button to light the pilot automatically when the gas valve is turned on.
This is more common in modern fryers for safety and convenience.

3. Lighting a Manual Pilot Fryer

If your fryer has a manual pilot system, follow these steps carefully:

1. Turn Off the Gas Control Knob and wait at least 5 minutes to allow any residual gas to dissipate.

2. Locate the pilot burner — a small nozzle usually near the base of the burners or behind a front access panel.

3. Turn the knob to the “Pilot” position.

4. Press and hold the knob or pilot button to allow gas to flow to the pilot.

5. Using a long lighter or match, carefully ignite the pilot flame.

6. Continue holding the knob for about 30 seconds so the thermocouple sensor heats up.

7. Release the knob — the pilot should remain lit. If it goes out, repeat the process.

8. Once the pilot stays lit, turn the knob to “On” to activate the main burners.

A properly lit pilot produces a steady blue flame touching the thermocouple tip. A yellow flame indicates poor combustion or a blocked air shutter, which should be cleaned or adjusted.

4. Lighting an Electronic Ignition Fryer

For modern fryers equipped with automatic ignition:

1. Ensure the power switch is off and the oil vat is empty.

2. Turn the main gas supply valve on.

3. Switch the fryer to “On” or “Pilot” mode as instructed by the manufacturer.

4. Press the ignition or spark button — you should hear a clicking sound as it ignites the pilot.

5. Once the pilot flame appears, wait a few seconds before turning the control to the operating position.

6. Fill the vat with oil and set your desired temperature.

If the pilot fails to light after several attempts, shut off the gas and wait a few minutes before trying again. Continuous attempts may flood the chamber with unburned gas.

5. Troubleshooting Lighting Issues

If issues persist after cleaning and inspection, contact a qualified gas technician.

6. After the Pilot Is Lit

Once your pilot and main burners are running:

• Fill the fryer with oil to the recommended level only.

• Monitor the flame color while heating. It should stay blue and stable.

• If the fryer will not be used for several hours, turn it off completely and close the gas valve.

Routine maintenance — such as cleaning burner ports, thermocouples, and filters — helps ensure reliable ignition and longer fryer lifespan.

Final Thoughts

Learning how to light a gas deep fryer properly keeps your kitchen safe and your equipment performing at its best. Always follow manufacturer guidelines, avoid shortcuts, and never attempt ignition if you suspect a gas leak.
Once lit correctly, your fryer will heat quickly, maintain stable temperature, and deliver crisp, consistent frying results.
