Two, the finish combustible or non-combustible material could be ended
below the fireplace (refer to Figure 53). Remove the floor panel as shown
in Figure 52 by removing the screws on the right side of the panel and
sliding the left side away from the tab. Discard the screws and floor panel.
It is critical that there is at least a 1/8 in. gap between the bottom of
