WARNING! Risk of Fire. A raised hearth extension built flush with the fireplace opening (Figure 11.3) or less than 4 in. (102 mm) below the fireplace opening requires the fireplace be installed on a non-combustible surface.

The hearth framing must be constructed of non-combus- tible materials (Figure 11.2) and placed on 1/2 in. Micore, or equivalent material (Figure 11.4). When creating the platform, allow for the thickness of the non-combustible finishing materials (Figure 11.5).
