Due to their quick light-up abilities, speedy step-up to the ideal temperature, and ease of cleaning, gas grills are the most popular choice among Americans—half of whom grill at least once yearly. Lighting a charcoal grill requires charcoal, more time and other tools like a chimney. Conversely, when lighting a gas grill, you just need to flip a switch…and keep the safety pointers ahead in mind.

How to Light a Gas Grill
Your grill's instruction manual should walk you through how to light a gas grill. But here's a general guide for lighting one, no matter what model you own.
-
Open the Lid
The first and most vital step when mastering how to light a gas grill safely is an easy one: open the lid. An explosion or severe flare-up can occur if too much gas builds up in the chamber just before igniting the grill.
-
Check the Gas Tank
Each propane cylinder should fuel between 12 to 18 hours of grill time, depending on the temperature level, the altitude, and the items you're cooking. It's wise to stock two propane tanks in case one runs out mid-grill.
-
Flip the Switches
Open the shutoff valve at the top of the propane cylinder, then turn on the gas grill burner knob to allow the gas to start flowing.
-
Hit the Ignition
Click the igniter button and keep pressing it until you hear and see it ignite. If the gas grill won't light at this point, turn off the gas and check the AA battery behind the igniter; it may need replacing.
-
Take a Beat
Wait for 20 seconds after you hear and see the ignition start. Carefully hold your hand about 6 inches above the grill to test the heat. The grill should be starting to feel warm. Light any burners you'll be using for direct or indirect grilling.
-
Preheat the Grill
Once your grill has been lit, close the lid to allow it to preheat for 10 to 15 minutes. When the grill temperature reaches 500° F, use a long-handled grill brush (one of our ten most essential grill tools) to clean the grates. Adjust the burners to hit the grill temp suggested in your recipe.
Troubleshooting
Keep the lid open if the gas grill won't light because it fails to ignite. Wait one minute to let any residual gas dissipate, then try these steps again.
Primary igniters sometimes fail, so if the ignition is not working, check your grill instructions to see if you can light it manually. Most models come with instructions for how to light a gas grill with a lighter, either through the cooking grates or via a match holder. Once you've found the best location for lighting a gas grill manually, turn the knob for the related burner to high/light. Carefully position the flame near the burner. Once it has been lit, gently remove the match or lighter from the area and ensure the flame on the flame starter has been extinguished.
Safety Tips to Keep in Mind When Lighting a Gas Grill
Propane gas is sold in small, pressurized tanks at most supermarkets, home improvement stores, hardware stores, gas stations, and convenience stores. Since it's colorless, it's challenging to tell when something goes awry. But you should be able to smell it—propane emits an aroma similar to rotten eggs or a skunk's spray. The tank will likely also make a hissing sound due to the pressure of the gas leaving the tank. Keep your ears and nose alert for these signs; if humans inhale a large amount of fumes from a leaky gas tank, they may be at increased risk for unconsciousness, asphyxiation, or cardiac failure.
Explosions and fires are rare but possible if a gas leak meets a spark or heat source. Store the propane tank and gas grill according to manufacturer instructions, and follow these gas grill best practices from the Hearth, Patio, and Barbecue Association.
