The extension should be set flush against the front of the fireplace front and measure 20”minimum at the front (1’-8” min) and 12” minimum (1’-0” min) beyond the sides of the fireplace opening as shown in Figures 10 and 12.  \nIf a raised hearth extension is being installed, it must be constructed of non-combustible material and any material under the structure must also be non-combustible.  \nIf using a raised hearth or metal base plate, note that a combustible wood header must be no closer than 2” to the top of the dome (see Figure 13) .  \nAttention: You will note that there will be a gap between the fireplace front and the extension of the non-combustible hearth material.
