Yes, you can use pea gravel, but only for natural gas fire pits. It’s important to note that while pea gravel can be used, it’s generally not recommended. If you do choose to use it, make sure to follow the same safety precautions and regulations as you would for using lava rock in a fire pit.
Pea gravel should never be used in propane fire pits, as it may trap gas, leading to potential safety hazards. Always ensure the gravel is dry before use, as wet materials can cause popping or explosions when exposed to heat.
For the safest and best results, consider using materials specifically designed for fire pits, such as lava rock or fire glass.
