With the right steps and a few quick safety checks, getting a gas grill going is a smooth process that only takes a couple of minutes.

Whether you're firing up for burgers, skewers, or something more adventurous, we'll help make sure your grill is lit properly and ready to cook.
What this article covers:
Tools & Supplies for Starting a Gas Grill
You don't need much to get started, but a few essentials make things smoother:
- A propane tank with fuel or a connected natural gas line
-
Grill brush (for clearing off the grates)
- Long-handled lighter or matches (in case the igniter fails)
- Safety gloves
- A spray bottle with soapy water (for leak checks)
Safety Checks Before You Start
Many people choose gas grills when deciding between a gas grill vs charcoal grill for their ease of use. However, although starting a gas grill is quicker than learning how to start a charcoal grill, there are still a few safety checks you should do before you begin:
Step 1: Open the Lid
Always start with the lid up. Never try to light your grill with the lid closed. Gas can build up inside and cause a dangerous flare-up when ignited. It's a simple check, but one of the most important.
Step 2: Check That All Burner Knobs Are Off
Before turning on the gas, make sure every control knob on the grill is in the "Off" position. This prevents gas from flowing to the burners before you're ready to ignite.
Step 3: Open the Gas Supply
If you're using a propane grill, slowly open the valve on the propane tank by turning it counterclockwise. If it's a natural gas grill, make sure your gas line is securely connected and the valve is open. Turning the valve slowly helps avoid pressure surges that can interfere with ignition.
Step 4: Check for Gas Leaks
Spray your soapy water solution around the hose, connections, and regulator. If you see bubbles form, that's a sign of a leak. Shut off the gas and inspect or replace the hose before proceeding. Never light a grill if you suspect a gas leak.
How to Start a Gas Grill
Step 1: Ensure the Lid is Fully Open
Before you go any further, make sure the grill lid is still open. You may have already done this during the safety checks, but it's worth double-checking.
A closed lid can trap gas, and that creates a real risk of flare-ups when the burner ignites. This makes a huge difference in safety. Leave the lid open until the burners are lit and the grill is ready to preheat.
Step 2: Open the Gas Valve
Now go to your fuel source. If you're using propane, turn the knob on top of the tank counterclockwise to open the valve. Turn it slowly so the gas flows evenly.
If you're using a natural gas line, make sure the shutoff valve is fully open. You might hear a soft hiss as the gas starts moving. That's normal. Some people also hover a hand near the burners, without touching anything, to feel for a faint flow of air that confirms gas is coming through.
Step 3: Light the First Burner
Pick the burner closest to the ignition system. This is usually marked on your grill, or it's the far-left knob if they're lined up. Turn that burner to “High.”
Now press the igniter button. Some models light instantly while others may take a few clicks. You should hear a clicking sound and then the whoosh of ignition.
Look through the grates or a built-in view window to confirm the flame is lit. If it doesn't light after a few tries, shut off the burner knob, close the gas valve, and wait at least a full minute before trying again.
Step 4: Light Manually if Needed
If your igniter won't work, don't worry. You can light the grill manually using a long match or a grill-safe lighter. Learning how to light a grill with a lighter is easy. Just make sure that you're wearing heat-resistant BBQ gloves.
With the lid open, place the flame near the burner's edge where the gas ports are located.
Then slowly turn the burner knob to “High.” It should ignite quickly. If it doesn't catch in a second or two, turn everything off, wait a full minute to let the gas clear, and try again.
Step 5: Light Additional Burners
Once the first burner is going, lighting the others is simple. Turn each additional burner knob to “High” one at a time. Most gas grills have a crossover system that transfers the flame from one burner to the next.
You should hear or see each one ignite as you go. If a burner doesn't light immediately, give it a moment and try again. Sometimes the flame just takes a second to reach the next burner.
Step 6: Preheat the Grill
Close the lid and let your grill heat up. Preheating takes around 10 to 15 minutes, depending on your grill model and outdoor conditions. Aim for a surface temperature between 350 and 500 degrees Fahrenheit, depending on what you're cooking. This helps sear food properly and also burns off leftover food bits or grease from your last cookout.
If your grill has a lid thermometer, use it to monitor the temperature. No thermometer? No problem. Hold your hand about 5 inches above the grate. If you can only keep it there for 2 to 3 seconds, it's ready.
Step 7: Adjust Heat Zones as Needed
Now that your grill is hot, fine-tune the burners to match what you're cooking. Leave one side on high for searing steaks or getting crispy edges. Turn the other side to medium or low for delicate items like veggies or fish.
This gives you more control and helps you cook multiple items at once without burning anything. Setting up heat zones is also how you pull off indirect grilling, which is perfect for slow-cooked ribs or larger cuts of meat.
Conclusion
With the right supplies, a few key safety checks, and a clear step-by-step process, you can get your gas grill fired up quickly and safely. From opening the lid and checking for leaks to lighting the burners and setting up heat zones, every step plays a part in getting your grill ready to cook. Whether you're grilling for the first time or just need a refresher, you're now set up for success.
