Finish Wall
Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12” (305
mm)above the firebox grille opening. Do not install a mantel face plate less than 6” (159 mm) from top of grille opening. (Fig. 20) If a combustible material is used below a flat mantel shelf, consult your local build- ing codes for minimum clearance from top of fireplace opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or deco- rative facing material meets fireplace surround must be completely sealed with a noncombustible material. (Figs. 21 and 25)
NOTE: No side wall protection is required for fireplaces installed at 45° to two (2) side walls (corner installation).

Mantels
The height that a combustible mantel is fitted above the fireplace is dependent on the depth of the mantel. This also applies to the distance between the mantel leg (if fitted) and the fireplace.
For the correct mounting heights and widths, refer to Figures 22 and 23. When using paint or lacquer to finish the mantel, such paint or lacquer must be heat resistant to prevent discoloration.

Side Wall Protection
Adjacent combustible side walls that are within mini- mum dimensions shown in Figure 25 of the fireplace opening must be protected with CFM Corporation Wall Shield Model SP40 or a specifically built wall shield described in Figure 20.
The special wall shield design described in Figure 20 is an alternate method of adding protection to side walls and can be used in place of the SP40 with the same wall clearances specified for the SP40. Rt must =1.85 minimum.
