LiteRock is a lightweight fireplace installation method that may be installed directly on a combustible surface , typically without
additional structural support. The LiteRock fireplace system is different from the standard installation because it does not require the
4”-6” concrete slab footing. The structural components, mix design, and style of the firebox itself are identical to our standard product
offering paired with an 8” metal riser and a lightweight metal chimney flue. The metal flue drastically decreases the chimney weight
that is typically seen with a standard masonry flue. The 8” metal riser is installed underneath the standard baseplate and provides
the necessary airspace clearance from the combustible floor system to the firebox.
*Important: Before installing onto the combustible floor system, it is important that the contractor has verified independently that the floor system is
able to withstand the weight of the installation.
