How to adjust gas grill burners? -

Don't let your new gas grill end up in the trash. With the increasing investment, a gas grill represents it, it is increasingly important to keep your grill running longer. That's why it's better and cheaper for you to know how to adjust gas grill burners.

1. Anatomy of a gas oven

1.1 The Tank

Years ago, your propane tank was nothing more than a tank. State-of-the-art propane tanks, authorized by the government for safety, contain an overfill prevention device (OPD). This makes it so a propane tank cannot be overfilled (see The New Propane Tank for more information). The OPD on your propane tank may be damaged causing the tank to not function correctly. This is rare, but it does happen.

The Tank

1.2 Fuel Hose and Regulator

The output of a propane tank or your natural gas flow is much larger than your grill needs so the regulator controls how much fuel can flow into your oven. The regulator attaches to the reservoir (or natural gas stream) using a flexible hose with an O-ring to create a hermetic seal. The regulator is preset by the manufacturer and should not be adjusted by you. If you look at your regulator, you'll notice a small vent in the center. Common problems here are clogged vents, which can cause irregular fuel flow and can lead to trouble. 

Fuel Hose and Regulator

Usually, you can clean it by tapping or blowing into the vent. Other problems are fuel leaks caused by a worn or damaged hose or O-ring. To determine if there is a leak, mix dish soap and water in equal parts and cover everything from the tank to the control valve. The tank needs to be connected and on but the control valve is off.

1.3 Control Valve

The controls do that, controlling the flow of fuel to the burner. Each burner on your grill will have a control valve. The valve consists of several components that are specifically designed on several elements. You cannot repair a bad control valve and if necessary, you should replace the entire unit.

Before you do, however, remove the control valve from your grill and test it. Like other parts of your grill, insects love to climb here and make their home. At the center of this is the hole. The holes control the flow of fuel and can become clogged. If so, use thin wire for cleaning. Make sure you put it all together the way you find it. Without the hole, you cannot control the amount of gas flowing into the burner and there is a risk of explosion.

1.4 Venturi Tubes

Venturi tubes connect the control valve to the burner(s) and mix fuel with air to provide a flame. To mix the air into the fuel, there is an open gap in the fuel line here that can easily clog. Insects, especially spiders, love this space and give it half a chance to move as quickly as possible. The best solution for this is to wrap the venturi tubes with an aluminum screen that will not block the airflow but will keep the critters out. These days many ovens come with protective venturi tubes. A common problem here is a misalignment of the venturi tubes with the burner. Usually the venturi tubes are simply placed in the fuel line and can be knocked out of place. The vents usually have adjustable shutters.

2.1. Burners

Burners come in many shapes, sizes, and materials specifically for your particular oven. What the burner is made of will tell you pretty much how long it will last. Burner from low-grade aluminized steel to high-grade brass and stainless steel castings. Low burners will usually last about 3 years under normal conditions. Because the burner is located inside the oven, it tends to get burnt by grease and can corrode quickly. Check and clean the burner regularly to avoid problems. If the burner is damaged or corroded too much, you will need to replace it. Have the same size and shape of the burner but consider buying a better quality metal if possible.

2.2 Barrier: In between the burner and the cooking groove is something

I call it a barrier; Some people call it radiant. It is called radiant because it is said to absorb and release heat evenly to the cooking surface. However, I don't find it very good here. The way I see it is that the barrier protects the burners from water droplets and creates a place for grease to collect and burn. Either way, what I'm talking about is 

lava rock, ceramic briquettes, or sheet metal. They need to be replaced periodically as they become broken down in fat and burned foods and can create an unpleasant taste in foods as they age. Lava rocks, because they are porous tend to need replacing more often. Sheet metal can often be cleaned and used for a longer period of time. Check your fence. If it's broken, heavily coated, or simply doesn't prove period barrier, consider replacing it.

2.3 Low flame: The grill just doesn't want to heat up

This can be caused by many things. Take it from the fuel source to the flame, let's start with the burner.

Newer propane tanks contain a self-regulating feature that will automatically slow the flow of fuel if it thinks it's too high. This can be solved by turning off the tank valve completely and disconnecting it. Open the control valves (on the grill control panel) and then close them.

Low flame: The grill just doesn't want to heat up

Reconnect the fuel tank and slowly turn on the valve. Now light the grill to see if that fixes it.

If not, check the control valve and vent hose for obstruction and alignment. Ensure that the fuel flow is continuous.

Check the burner for clogged air holes. You can usually see this problem by observing how the grill burns. If there are spots with no flame then you may have a clogged burner.

2.4 Uneven heating: One side or area of ​​the oven is much cooler than the rest.

This problem is similar to the low flame problem. Check if there is any solution. If you have multiple burners determine if one will burn hotter than the other.

  • Yellow or Orange Flame: The flame should be blue with yellow tips.

  • Try cleaning the burner or letting it burn for 15 minutes.

  • The Venturi tube may not be properly aligned.

  • Venturi shutters may need adjustment. Do this by first locating the venturi tube adjustment screw.

This screw releases the shutters. Light the oven and turn to low. Loosen the screw and open the shutter until the flame is mostly blue. Turn off the gas and tighten the adjusting screw. Let the grill cool.

2.5 Grill produces a lot of smoke

There is usually a large amount of grease in your grill. Give it a good clean and preheat for 15 minutes to burn off any residue.

Flames from under the grill, behind the control panel

This is because the venturi tube is misaligned or blocked. After the grill is cooled, check to make sure all parts are assembled. Be sure to check hoses and fuel lines to make sure they aren't cracked, melted, or burned through.
