Things You Need to Know Before Cleaning Grill Burners

Gas Grills have many parts that make the grilling experience better. Let’s take a closer look at what these parts are and what they do.

The gas grill consists of a burner tube, a gas valve, a grate, and an adjustable drip tray.

The first part that needs to be taken care of is the burner tubes. These tubes allow for a direct flow of gas from the gas valve to the burners, which in turn create an even flame and heat across the whole grill.

A burner tube is used for cooking with direct heat from the burners. It is surrounded by a metal ring that allows air to pass through the tubing.

The second part gas valve regulates the input of fuel into the burners that are mounted at one end of the tube. The other end is called an end cap that controls the flow of air into and out of the tube.

The third part is the grill grates. The grates come in different shapes and sizes, and materials. They can be made out of iron, steel, aluminum, and porcelain.

These materials will protect the food from the fire and will ensure that it cooks evenly over the heat source.

The grate has an opening that lets grease drain into a drip tray below it, which is also one of most important components as it helps control flare-ups by catching grease drips.

Why You Need to Clean Your Gas Grill Burner

If you notice the performance of your grill has dropped a little bit it may be because tubes are dirty.

If your grill is not reaching the desired temperature during pre-heating time grill tubes may need to be cleaned. This performance issue is caused by scaling on burner tubes.

The scaling on burner tubes can occur because of dirt, grease, moisture, carbon, and oxidation from cooking over time.

The scaling would cause the holes on tubes to become smaller which provides the lesser flame.

The burner tubes need to be cleaned regularly to prevent them from getting clogged and to avoid potential fires.

Cleaning the burner tubes ensures even heating and prolonged use and you should actually do it at least once a year

Cleaning your grill regularly is a good idea for three reasons: you’ll prevent buildup from occurring, it helps make them last longer, and if you use the grill often it’s a good idea to clean them once a month.

A burner in your gas grill is a hollow tube made of metal that you fill with gas. The small openings along the length of the burners are called ‘portholes’ and are very important.

These areas deal with the air that travels over them, keeping everything running at peak performance.

Common Defects in the Flame Patterns Because of Clogged Burner Tubes

The defect in the flame patterns and their color is a good indicator of the health of the burner tubes.

A yellow flame means a crack in your burner tube

There is a large, yellow flame with an uneven shape which means there is a crack in the burner tube. The crack means that the fuel has been mixed up with air and has burned unevenly.

If there are any cracks, it is unsafe to use the grill and you should get it repaired or get a new burner tube from the manufacturer.

Blue-colored uneven Flame means holes on the burner tubes are clogged

If blue flames are seen, it means that some of the portholes are clogged and can cause your grill to shut off unexpectedly.

No flame

When you notice no flame coming from your burner, the first thing to check is the flow regulator. If it’s defective or clogged, replace it.

A burner tube with no flame is a warning sign that there is something wrong with the flow regulator or blockage in the orifice into the burner.

The device must be turned off and serviced as soon as possible, otherwise, a fire could result.
