The Right Way to Light a Gas Grill Safely

Gas grills are a favorite among Americans thanks to their fast ignition, quick heat-up time, and easy cleanup. In fact, about half of Americans fire up the grill at least once a year. Unlike charcoal grills—which require coals, time, and tools like a chimney starter—gas grills can be lit with the push of a button… as long as you follow a few important safety tips.

Read on to learn how to safely light your gas grill and be just minutes away from your next backyard feast. Plus, we’ll cover how to manually light your grill if the igniter isn’t working.

How to Light a Gas Grill

Your grill’s manual should have model-specific lighting instructions, but here’s a general step-by-step guide that works for most gas grills.

1. Open the Lid
The most important step for safety is to always open the lid before lighting your grill. If gas builds up inside a closed lid, it can cause a dangerous flare-up or even an explosion when ignited.

2. Check Your Propane Tank
A standard propane tank usually lasts 12 to 18 hours depending on your grill’s temperature settings, elevation, and what you’re cooking. It’s smart to keep a second tank on hand in case one runs out mid-BBQ.

3. Turn On the Gas and Burners
Twist the propane tank’s valve to open it fully. Then, turn the burner control knob to start the gas flow.

Press the Ignition Button
Press and hold the igniter button until you hear the click and see the flame. If your grill doesn’t light right away, shut off the gas and check the igniter battery (usually a AA battery located behind the button). Replace it if needed.

4. Test for Heat
After ignition, wait about 20 seconds. Carefully hover your hand 5 to 6 inches above the grill grate—you should feel heat rising. Once confirmed, light any additional burners you need for direct or indirect cooking.

5. Preheat the Grill
Close the lid and let the grill preheat for 10 to 15 minutes. When it reaches around 500°F, use a long-handled grill brush (a must-have BBQ tool!) to clean the grates. Then adjust the burners to the temperature your recipe calls for.

Troubleshooting: What If Your Grill Won’t Light?

If the grill doesn’t ignite, keep the lid open. Wait at least one minute to let any excess gas dissipate before trying again.

If the igniter still won’t spark, check your grill manual for instructions on manual lighting. Most gas grills can be lit with a match or long lighter using a special match-light hole or match holder.

To do this safely:

• Turn the burner knob to high.

• Carefully bring a lit match or lighter close to the burner.

• Once it ignites, pull your hand back slowly and make sure the flame is stable.
