Our 24 Inch fire logs are designed to mimic the look of wood logs. It also has cracks through which the flames come out to make it look as though the log is burning. Our fire log is built for fire pits that are fueled by natural gas or propane. It's one accessory that will elevate your fire pits' appeal. The metal construction of our artificial logs absorbs the heat produced by your fire pit. They then radiate this heat outwards to warm up the immediate and surrounding areas. Putting together our artificial fireplace logs is pretty straightforward with the interlocking branch on the side. Please note that each piece is sold separately, and NOT FOR INDOOR USE. These logs get too hot to use with remote start or auto start mechanisms and will damage the mechanisms. Recommended for use on fire pits with manual on/off key, or manual on/off lever only.
