Hearth and Home Technologies EM-415 Finishing Material, Mantel, Glass Doors, Combustible Material

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.

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 or 76R, Nuflex 302, GE RTV106, 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 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 metal fireplace front.

¨ WARNING

Fire Risk

•Maintain clearances.

•Use only non-combustible material below standoffs, material such as cement board is acceptable.

•Framing or finishing material used on the front of, or in front of, the appliance closer than the minimums listed, must be constructed entirely of noncombustible materials (i.e., steel studs, concrete board, etc.).

WARNING

Fire Risk

Do NOT obstruct air inlet or outlet grilles.

Do NOT modify grilles.

•Modifying or covering grilles could cause temperature rise and fire hazard.

Finishing materials must not interfere with:

•Air flow through grilles or louvers

•Operation of louvers or doors

•Access for service

C. Mantel

A combustible mantel may be positioned no lower than 12 in. (305 mm) above the top of the fireplace opening. The combustible mantel may have a maximum depth of 12 in. (305 mm). Combustible trim pieces that project no more than 1-1/2 in.(38 mm) from the face of the fireplace can be placed no closer than 6 in. (152 mm) from the top of the fireplace opening. See Figure 8.4. Combustible trim must not cover the metal surfaces of the fireplace. This mantel clearance is in accordance with Section 7-3.3.3 of ANSI/ NFPA211.

D. Sidewalls/Surrounds

Adjacent combustible side walls must be located a minimum of 12 in. (305 mm) from the fireplace opening. If you are us- ing a decorative surround constructed of combustible ma- terial, it must be located within the shaded area defined in Figure 8.5. Short stub walls are also acceptable if they are contained within the shaded area.

WARNING

Fire Risk

Finish all edges and fronts to clearances and specifications.

•Metal fireplace front may be covered with non- combustible material only.

•Do NOT overlap combustible materials onto fireplace front.

•Install combustible materials up to specified clearances on top front and side edges.

•Seal joints between the finished wall and fireplace top and sides using only a 300° F minimum sealant.

E. Glass Doors

This fireplace has been tested and listed for use with doors as specified in Section 12.B. Fireplace Components. Please refer to the manual packed with each set of doors for instal- lation instructions.
