7. Finish Wall
Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12 inches above the front opening. If a combustible material is used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fireplace opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or decora- tive facing material meets fireplace surround must be completely sealed with a noncombustible material. (Figs. 18, 19, 20)
Note: No side wall protection is required for fireplaces installed at 45 degrees to two (2) side walls (corner installation).
