Heat & Glo LifeStyle Montana-42 Combustible Material, Non-CombustibleMaterial, Fire Risk

B. Finishing Material

•Combustible Material

Material which is made of or surfaced with wood, compressed paper, plant fibers, plastics, or any material capable of igniting and burning, whether flame 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.

•Non-Combustible Sealant Material

Sealants which will not ignite and burn: Rutland, Inc. Fireplace Mortar #63 (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 fireplace and facing to prevent cold air leaks. Large gaps can be bridged with fiberglass rope gasket.

Only non-combustible materials may be used to cover the black metal fireplace front.
