the fireplace surround (top/sides) must be sealed with
noncombustible material to prevent cold air leakage into
the room. Only noncombustible material may be applied

install a combustible mantel shelf less than 12"
(305 mm) from top of grille opening for circulating
models. Do not install a mantel face plate less than
3" (76 mm) from top of grille opening for circulating
models. (Fig. 20) If a combustible material is used be-
low a flat mantel shelf, consult your local building codes
for minimum clearance from top of fireplace opening to
