Fire Pit Media Popping: Please be aware that fire pit media such as fire glass, lava rock, ceramic stones, and similar materials may pop or jump during use. This can occur when moisture is present either within the media or in surrounding air pockets. When heated, trapped moisture rapidly turns to steam, causing sudden pressure that may result in the media cracking, shifting, or projecting small fragments.

To Reduce Risk:

Always use dry media.
Store media in a moisture-free environment.
Light fires gradually to allow for safe heating.
Use caution and maintain a safe distance during initial ignition and operation.

Soot Build Up: Gas burners—whether fueled by Natural Gas or Propane—may naturally produce some soot or black residue over time. This is a normal byproduct of combustion. Natural Gas typically burns cleaner, while Propane, being a heavier gas, may produce more visible soot. However, excessive or rapid soot buildup may indicate issues such as improper burner installation, incorrect gas-to-air ratios, or obstructed or poorly placed fire media.

To Minimize Soot Accumulation:

Ensure professional installation.
Follow manufacturer guidelines for media placement.
Periodically inspect and clean burner components
Always operate gas burners in well-ventilated areas and monitor for signs of abnormal performance.
