B. Finishing Material
• Combustible Material
Material which is made of or surfaced with wood,
compressed paper, plant
¿ bers, plastics, or any material
capable of igniting and burning, whether À ame proofed or
not, plastered or not plastered.
• Non-Combustible Material
Material which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, concrete,
slate, glass or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750° C, shall be considered
non-combustible materials.
• Non-Combustible Sealant Material
Sealants which will not ignite and burn: Rutland, Inc.
Fireplace Mortar #63, Rutland 76R, Nuflex 304, GE
RTV106 or GE RTV116 (or equivalent).
After completing the framing and applying the facing material
(drywall) over the framing, a bead of non-combustible seal-
ant must be used to close off any gaps at the top and sides
between the
¿ replace and facing to prevent cold air leaks.
Large gaps can be bridged with ¿ berglass rope gasket.
Only non-combustible materials may be used to cover the
metal
¿ replace front.
