Steps On How To Place Lava Rocks In Gas Grill
1. Create A Single Layer Of Lava Rocks
It is important to think about how you are going to set the lava rocks into place.
One method people take is to start tossing the lava rocks in without reason. This ends up creating an even setup, which is not going to help prep the gas grill as it needs to be.
The best solution is to focus on creating a single layer of lava rocks.
To do this, you are going to place the lava rocks on the grate over the burner. This is going to ensure you have a seamless finish that is in line with what the gas grill requires.

2. Keep The Edges Pressed Against Each Other
You are also going to want to pay attention to how the lava rocks are set up next to each other.
This is far more important than you realize.
The goal is to keep the edges pressed against each other.
If you do this, you are going to ensure there are no gaps between the lava rocks. When there are gaps, the taste profile is going to be off and inconsistent.
Always look into this to make sure you are taking the right approach and not ruining the taste profile.
3. Turn On The Heat
You will want to turn on the heat as soon as the edges are pressed against each other and you are certain the lava rocks are in good shape.
This is essential.
You will want to turn on the heat and wait for the preheating process to finish.
The goal during this process is to see whether or not the lava rocks are in the order they need to be. This includes ensuring they are not stacked on top of each other.
If they are stacked on top of each other, you will want to turn off the heat and rearrange them as soon as possible.

4. Close The Lid And Wait 15 Minutes
It’s important to close the lid and wait at least 15 minutes.
The reason for doing this is to make sure you are not creating a situation where it continues to cool down.
This will make it difficult to use the gas grill as you want to use it.
Closing the lid is a good step and all it is going to take is 15 minutes for the heating process to finish. At this point, you can then begin to work on using the gas grill with the lava rocks.
Final Thoughts
These are the main steps on how to place lava rocks in a gas grill.
To place lava rocks in a gas grill, it’s best to start by creating a single layer with the edges pressed against each other. Make sure to do this on the grate over the burner for maximum results and do not stack the lava rocks on top of each other. Once done, turn on the heat, close the lid, and wait at least 15 minutes.
This is all you are going to have to do to get the results you are after.
Lava rocks are a good solution but you have to create a robust layer that is in line with what your gas grill needs. Until then, you are not going to see good results.
