7100FP EPA Woodburning Fireplace

C.Position the Hearth Extension

Position and secure the hearth extension over the protective metal strips that have been placed partially under the fireplace front. These strips should be protruding approximately 2 in. (51 mm) from under the fireplace front and 2 in. (51 mm) on both sides of the fireplace opening. See Figure 19.1 on page

19.Seal the crack between the hearth extension and fireplace with a bead of non-combustible sealant. See Figure 41.1. Apply a non-combustible finishing material of your choice to the hearth extension.

NOTE: SEE PAGES 10-12 & 38 “CLEARANCES TO COM-

BUSTIBLES, HEARTH EXTENSIONS / FLOOR PROTEC- TION” FOR CLEARANCES REQUIRED FOR DIFFERENT HEARTH EXTENSION INSTALLATIONS. THE CLEAR- ANCES MUST BE STRICTLY ADHERED TO.

WARNING

Fire Risk

•Hearth extensions are to be installed only as illustrated to prevent high temperatures from occurring on concealed combustible materials.

•Hearth sealing strips prevent burning or hot particles from inadvertently falling directly on combustible surfaces in the event the building should settle and disturb the original construction.

D. Finishing Material

Do not install combustible materials over the metal fireplace face of the fireplace! This poses a safety hazard and may start a fire. You may only use non- combustible material over the metal face of the fireplace.

NOTE: The decorative fascia must be removable for future serviceability of the Automatic Combustion Control.

•Combustible Material

Materials made of or surfaced with wood, compressed paper, plant fibers, plastics, or other materials that can ignite and burn, whether flame proofed or not, or whether plastered or un-plastered shall be considered combus-

tible materials.

•Non-Combustible Material

Materials which will not ignite and burn. Such materi- als 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, Stan- dard Test Method for Behavior of Materials, in a Vertical Tube Furnace at 750°C, shall be considered non-com-

bustible materials.

•Non-Combustible Sealant Material

Sealants which will not ignite and burn: Super Calstick

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.

•Cardboard OR Metal Template

A cardboard template of the front is printed on the outside of the shipping box. It measures 1/8 in. (3 mm) bigger all the way around than the actual front. Cut out the template along the outside of the line for use in your installation.

A metal template is also available for more durable continued use remaining accurate over time. (See Section 12.E).

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.).
