How to light a gas grill: Step-by-step guide

Step 1: Safety first

Before you begin, it is essential to ensure that you're not using your grill in an enclosed area. This is a crucial safety measure that helps prevent accidents. Also, make sure that the weather conditions are not too windy. If they are, you may need to move your grill to a more sheltered area.

Next, check that the fittings on the gas cylinders are secure and that there are no signs of leaks. Turn off all burners and slowly turn the valves to release the gas. Wait for about 60 seconds for the gas to travel along the line.

Step 2: Open the grill lid

When lighting a gas grill, it is essential to open the lid first. This step is crucial because if you turn on the ignition before opening the lid, the gas could build up in the grill chamber and cause an explosion. Therefore, always leave the lid open before lighting the grill. Also, avoid lighting the grill in an enclosed space, as this poses a fire hazard.

Step 3: Turn on the gas

Next, turn on the gas in the propane tank. If you're using a natural gas grill, the gas should be constantly pumped into the grill.

Step 4: Turn on the burner

To start your gas grill, begin by turning on the gas. Then, turn on one of the gas burners by using the knob on the grill. After that, turn on the burner that is closest to you. If your grill is a premium model, you can start the ignition by either twisting a knob or pressing a button. The spark from the ignition will create a flame when it touches the gas. You can light your grill with a match if there is no ignition, but use a long-handled match to avoid burning your fingers.

Step 5: Ignite the grill

It's time to light up the grill. If your grill has an auto-light or ignition button, press it. In case there is no ignition button, turn the knobs until you hear a cracking noise and wait for the flame to catch.

Step 6: Check for ignition

After you hear the ignition and see the flame, wait for about 20 seconds. Then, hold your hand about 6 inches over the grill and leave it there until you feel the heat. This will ensure that the burner is lit and stays lit.

Step 7: If the grill doesn't ignite

If your grill fails to ignite, open the lid and air out the cook chamber. Wait a minute, and then try starting it again. If your grill has holes in the bottom, try lighting a match near the burner from that position. If not, you can use a long match from the top. And, if none of those are available, you can throw a game near the burners. However, please be careful while doing so. If you are struggling with the ignition, and it doesn't light within ten seconds, turn off the gas for thirty seconds before attempting to light it again. This pause will prevent excess gas from being released, which could result in a huge flame.

Step 8: Preheat the grill

After lighting your grill, close the lid and let it preheat for 10 to 15 minutes. Wait until the temperature reaches 500°F before proceeding to the next step. Once the first burner is lit, turn on the other burners and wait five minutes before cooking. This will let your grill warm up properly and burn off residual grease.

Step 9: Clean the grates

Clean the grates with a long-handled grill brush to ensure even cooking and to prevent food from sticking to the grill.

Step 10: Adjust the burners

Adjust the burners to reach the grill temperature recommended by your recipe. Your grill is now ready for cooking!
