LiteRock Modular Fireplace ApplicationThe LiteRock Installation Application

LiteRock is a lightweight fireplace system that may be installed directly on a combustible surface, typically without additional structural support. The components of the LiteRock system include a FireRock fireplace, lightweight metal chimney, and a metal riser kit to elevate the firebox off of the combustible surface.

It is important to understand that “LiteRock” is an installation method, not a completely different kind of firebox. The firebox itself is exactly the same as one used in a standard installation method. The LiteRock System is simply an installation method that allows the system to be installed onto a combustible floor.

LiteRock Elements

Manufactured and provided by FireRock, the LiteRock riser is available in 3 sizes: 30”, 36”, and 42”. This allows the LiteRock installation method to be an option for any Conventional, Rumford, or See-Thru fireboxes up to 42” inches in size. The Literock system is not approved for any sizes larger than 42”.

The LiteRock fireplace system is different from the standard installation because it does not require the 4”-6” concrete slab footing.* While the structural components, mix design, and style of the firebox itself are identical to our standard product offering, a LiteRock is 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.
