How To Make A Gas Grill Hotter – Hotter And Better Than Ever

A flame is necessary to generate heat for cooking on a gas grill. Do you find yourself struggling to get your gas grill hot enough to achieve that perfect sear or char? If you’re wondering why your barbecue isn’t getting hot enough, there are a few easy tricks you can try before you look into replacing parts or getting a brand new grill. 

Low temperatures and uneven heating are usually easily solved in just a few simple steps. But before you start troubleshooting, understand how your gas grill works so you can more easily determine what parts might be causing the issue.

DEMONSTRATE HOW YOUR GRILL WORKS

Process of Gas Grill

1. Gas grills use propane or natural gas as fuel to heat up burners beneath the cooking grates
2. Regulator controls gas pressure and manifold splits it between different burners
3. Control valve adjusts temperature by make adjustments to flow rate
4. Gas mixed with oxygen in venturi tubes and ignited in burners to create visible flames
5. Heat plate above burners aid in heat distribution and catch food drippings

In summary, the gas ignites to create visible flames on the burners, which then transmit heat to the cooking grates.

Issues on Gas grill

If you spot any issues like low temperatures and uneven heating or if turning the control knobs doesn’t increase the size of the flame. 

It is very important that your gas grill has the right BTU. You may have an issue with the regulator or burners, or there may be a blockage in one of the tubes. There are numerous factors that frequently result in low or no flames:

• A near-empty propane tank
• A damaged port or component, such as a faulty regulator or corroded burners
• The flow-limiting device has been activated.
• Poor connections

Some major problems :

Worn-Out Grates
Old, rusted grates can absorb heat, reducing the temperature of the cooking surface.

Poor Airflow
Airflow is crucial for maintaining a strong flame. Blockages in the grill’s venting system can affect the quality of the flame and reduce heat.

Cold Outdoor Temperatures
Grilling in cold weather can affect the efficiency of the gas grill. The grill will have to work harder to maintain the desired temperature, often failing to get as hot as it should.

If your barbecue isn’t getting hot enough or is heating unevenly, the first thing you should always do before troubleshooting is turn off the tank valve and disconnect the propane tank from the grill.

If your grill is on, make sure it’s completely cooled before disconnecting the tank. If the gas was on, give it 5 minutes so the gas can dissipate before you troubleshoot.

HOW TO FIX LOW FLAMES AND LOW TEMPERATURES

Low Flame

If you’re experiencing low flames and low temperatures , start by resetting your grill’s gas regulator. 

We can even help you figure out how to fix this problem with your Weber gas grill not heating up enough. 

All gas grills have a propane regulator that controls the flow of gas from the propane tank to the grill, and this regulator is one of the most common reasons why a barbecue is not getting hot enough.

Low Temperature

The flow-limiting device prevents the grill from being overfilled with gas. It’s easy to accidentally activate this safety device even if you don’t have a gas leak and your grill is in something called “bypass mode”. 

When this happens, your grill will only ever reach temperatures between 250 and 300, even with all the burners turned to the highest setting.

How Bypass Mode is Triggered

• Rapid On/Off: Quickly opening and closing the gas valve can trigger the safety feature.
• Leak Detection: If the regulator detects what it interprets as a gas leak (which could be as simple as not properly turning off the burners before opening the gas supply), it may go into bypass mode.
• High Flow: Similar to leak detection, a sudden high flow of gas can activate the safety feature.

How to Reset from Bypass Mode

1. Turn Off Everything: Make sure all the grill knobs and the propane tank valve are in the off position.
2. Disconnect and Reconnect: Disconnect the gas line from the propane tank, wait for a few minutes, and then reconnect it.
3. Slow Valve Opening: Very slowly open the propane tank valve. A quick turn may trigger the safety feature again.
4. Ignite Burners: Turn on the grill burners one at a time, starting with the one closest to the gas supply.

Adjust Air Shutter 

It is important to note that not all gas grills have air shutters that can be adjusted. If you use your gas grill frequently, you may need to adjust the air shutter more often. This is because debris and grease can build up on the burners and affect the air-to-gas ratio.

Here are the steps to adjust the air shutter on a gas grill:

1. Light your gas grill burner.
2. Disconnect the front control panel to reveal the burner or venturi tube valves and manifold
3. Loosen the screw on the air adjustment
4. Slide or turn the air adjustment to adjust the mixture of gas and air in the burner
5. Test fire the burner to see if you get blue flames with yellow tips
6. If the setting is good, remove the burner and tighten the screw to hold the air adjustment in place
7. Adjust remaining burners to the same setting

HOW TO CHECK A GAS BBQ FOR GAS LEAKS

Checking for gas leaks is a simple and quick process that should be performed each time you connect your regulator or hose to your barbecue or after long periods of storage. Follow these steps to test for a gas leak:

1. The first step is to ensure your gas supply is turned off and all control knobs are in the off position.
2. Secondly, inspect all hoses on the grill, looking closely for signs of deterioration such as cracking, abrasions, holes, or tears.
3. Ensure all the hoses are tightly connected and that there are no sharp bends or kinks in the gas line.
4. Check the gas cylinder for rust, dents, bulges, corrosion, punctures, or other signs of damage.
5. Mix a 50/50 solution of water and dish soap and apply it to the gas hose and connection points with a spray bottle or a clean brush.
6. Open the gas supply, but do not turn on the control knobs or light the grill. Do not smoke while testing for gas leaks.
7. Inspect the hose and connection points. If you see growing bubbles forming at any point, this indicates a gas leak.

Checking for a gas leak is also a great opportunity to ensure all the connections are tight and secure. Loose connections can also result in low temperatures and pose a fire risk.

How to Check for Obstacles

If you have high heat but it’s uneven or you’re seeing a yellow or orange flame, the venturi tubes may not be properly aligned with the burner, or the burner may be obstructed by food debris or insects. 

Start by checking that the burner tube is properly seated on the gas valve. If the burner alignment looks okay

Then remove the burners and use a bottle brush or special venturi brush to clean out the venturi tube of each burner—spiders and insects like to set up shop in these tubes and are a common source of blockages. Remember to clean and maintain gas grill regularly so that burner tube is working properly. 

The third thing to check is if any of the burner port holes are clogged. 

WHY IS MY BBQ STILL NOT GETTING HOT ENOUGH?

If you’ve reset the regulator, checked for leaks, tightened the connections, and cleared away obstructions and your grill still isn’t getting hot enough, you may need to replace some grill parts.

If you’re setting up a new grill, knowing how to break it in can make it last longer.

• If the flames are consistently low, you may need a new propane regulator.
• If the flames are hot but uneven, you may need to replace the burner.
• If all troubleshooting fails and your grill is still not heating, visit a professional grill expert or contact the manufacturer’s customer service. 
• If you have expanded the gas line or modified your grill, make sure the gas line diameter matches the length and number of burners.

CONCLUSION

Did you know that, on average, Americans replace their gas grill after just three years? A big factor in how long your gas grill will last is the level of care and maintenance you give it. Achieving a hotter gas grill is easy with the right steps. Don’t let your grilling activities suffer because of the low heat. Pay attention to preheat, clean, and check all the details before you turn that knob. You can easily make your gas grill hotter!
