From rock preparation to making a perfect base, we’ll teach you the best way to approach this so you can enjoy it as much as possible. So, grab your lava rocks and let’s get started!
What are lava rocks:
Lava rocks are essentially the solidified remains of lava from volcanic eruptions. Known as igneous rocks, they are lightweight and porous. They form in the aftermath of an eruption, when molten lava is rapidly cooled, resulting in rocks that have a distinct look and texture. They have air pockets and are irregularly shaped. Over time, lava rocks have been prized for their durability and ability to withstand high levels of heat. As a result, they have been used in a variety of ways over the years, mainly in applications like landscaping, gardening and have become popular to use as fire pit media. Since they are fossilized in nature, they excel at transferring heat. In fact, these types of outdoor fire pit media are the best for a propane fire pit, as they optimize the heat better than any other material. Lava rocks come in a range of shades, from a deep brown to a reddish-brown, which can complement any landscape. Plus, they are available in single bags, serving sizes or bulk quantity, which is convenient for homeowners and professionals.
Choosing the Right Lava Rocks:
Choosing the right lava rocks is integral when using in a propane fire pit, ensuring optimal performance and visual appeal. Be sure to choose rocks that are specifically made for use in fire pits so that you can guarantee their fire resistivity and safety. Also, you’ll want to select the appropriate size and shape of lava rocks, so that they fit well in your fire pit and allow for proper airflow and heat distribution. Selecting the right color of lava rocks is essential, especially if you have an outdoor fire pit and want to match the color with your outdoor setting. Lava rocks are usually available in black, brown and red, which adds to the natural appeal of your fire pit. And lastly, it’s important to determine the amount of rock needed for your fire pit. Determine this based on the appropriate number of rocks you will need for the specific size of your fire pit. Too many rocks can cause interference with the gas flow and can damage the fire pit as a result. Consider using an online lava rock calculator.
Placing the Lava Rocks: step-by-step guide
1. Prepare the Fire Pit:
Before placing lava rocks in your propane fire pit, turn off and cool down the fire pit completely. Remove any ashes, debris, or other materials from the fire pit to have a clean surface to start with.
2. Layering:
Depending on the size and depth of your fire pit, you may choose to add multiple layers of lava rocks.
Using a Base Layer of Smaller Rocks:
When you place lava rocks into your propane fire pit, you might consider starting with a small layer of rocks at the bottom. This not only aids in draining if your fire pit is out in the open, but it also provides a good, small base for the larger lava rocks to sit on. In addition, lava rock is already attractive and will provide your propane fire pit with a visually appealing appearance before you add the much larger rocks.
Filling the Fire Pit with Larger Lava Rocks:
Once you have your bottom layer established, fill the fire pit with larger lava rocks. You will want to shoot for anywhere from 4-5 inches deep. However, you can adjust this depth to your fire pit size and personal preference. When placing your lava rocks, don’t obstruct the burner jets in the middle. Fill the fire pit with the rocks, taking care to avoid over-filling the pit, as this can impede the proper operation of the burner. Be sure to spread the larger rocks consistently to keep the fire pit both functional and visually appealing.
3. Adjust as Needed:
Once you have placed all the lava rocks in your propane fire pit, do a test ignite. Turn your propane supply on and light the fire pit. You want to be sure the flames are burning evenly amongst all the rocks. If, for some reason, you have rocks where the flame is not reaching, adjust the position for those rocks. Also if you have an area that the flame is getting stuck in, try moving those rocks around for better airflow and heat distribution Monitor the flame’s performance and continue to make adjustments until the flames are evenly distributed and reach all your lava rocks. Remember your safety precautions and be aware that those rocks can be scorching hot so make sure to have heat resistant gloves or tongs.
With these steps, you’ll be able to fill your propane fire pit with lava rocks to create a useful and beautiful fire element for your outdoor living area. If you are considering to add glass rocks to your fire pit, make sure to read our blog on how to place glass rocks in propane fire pit.
How to Clean Lava Rocks:
A regular cleaning routine will keep your lava rocks looking their best and functioning properly. First, remove the rocks from the fire pit. Use a stiff brush to clean loose material and debris from the rocks or, if your rocks will permit you to do so, blow out the material with compressed air. If you have stubborn soot or debris on the rocks: soak the rocks in a tub of warm water with a gentle liquid dish soap for 20-30 minutes and scrub carefully. Rinse well with clean water and completely dry your rocks before using them again in your fire pit. Regular cleaning can aid in the efficient distribution of heat and will ensure that your fire pit it showcases properly.
When to Replace Lava Rocks
Lava rocks, just like anything else that you use outdoors, can have a limited life expectancy. After you use them for a while, you should periodically inspect them for wear, cracks, crumbling, or other deterioration, which would be the most obvious signs that you need new lava rocks. If your fire pit’s performance seems to flag, with weak, uneven flames or low heat output, new lava rocks might be in order. You can occasionally clean the rocks with a pressure washer or replace the rocks completely. Over time, the rocks will get dirty and will not work efficiently. Typical usage calls for replacing lava rocks if you have not done so within two years.
