Use replacement lava rocks to renew and replace the original rocks that came with your gas or propane fireplace or log set. These glowing lava rocks decorate the firebox of both propane and natural gas fueled units. Distribute the lava rocks liberally over the sand or vermiculite in the firebox (log sets) or follow your manual’s instructions to restore the newness and realism of your fireplace. Mostly black in color with some reddish brown mixed in.
Please ensure to follow specific instructions in your manual when using lava rocks. Although home owners are capable of replacing these, we do recommend that a fireplace technician be hired when handling this product.
