LITEROCK INSTALLATION METHOD
(CONTINUED)
FLUSH HEARTH WITH LITEROCK RISER
If the design calls for a flush hearth, special consideration must be taken before lowering and setting the LiteRock on the joist
system. When calculating flush hearth height, be sure to account for both the 3” LiteRock riser, the 3 3/4” base plate, and the 2 1/2”
thick firebrick floor (a total of 9 1/4”).
Whether using a flush hearth or a raised hearth, a noncombustible hearth extension must cover the combustible floor at least 20”
out in front of the finished firebox opening and 8” beyond the finished sides of the opening.
IMPORTANT:
When installing the LiteRock Riser as
a flush hearth application, the noncombustible hearth
extension must be supported by noncombustible materials
(Figure 16.6). All materials that abut the fireplace or riser
material must be noncombustible.
The FireRock base plate is mandatory for the LiteRock
Installation Method. Failure to use a base plate with this
installation method may result in a fire or explosion,
causing property damage, personal injury, or loss of life.
