This hearth extension may be either minimum 6-inch thick stone or brick as shown by Figure 10, an H2066 Hearth Extension Kit or a locally constructed hearth equivalent to the H2066. The insulation used in the H2066 hearth extension has a thermal conductivity (K Factor) of .43. If you do construct a hearth extension equivalent to the H2066, be sure the insulation you use has enough compressive strength to support the weight of the covering materials and persons standing on it, and insulating qualities equal too or better than the ." covering provided by the H2066. 12"..

GAS OPENING JUNCTION BOX OPENING HEARTH EXTENSION FLOOR PROTECTION With either type hearth extension minor shifting of the supporting floor or expansion and contraction may eventually cause a crack to develop between the hearth extension and the face of the fireplace. To help prevent the crack from developing, the hearth extension materials must be firmly fastened in place. Wall ties should be screwed to the face of the fireplace and imbedded in the mortar joints of brick, stone, or other noncombustible materials. The metal safety strip packed with the fireplace must be placed beneath the fireplace and extended under the hearth extension or into a mortar joint of the hearth extension as shown by Figures 10, 11, and 12. In the event a crack does eventually develop, the metal safety strip will serve as a barrier to prevent sparks or embers from falling from the fireplace onto combustible flooring materials. The hearth extension must not block the side air vents, or air inlet louvers on the lower front of the fireplace. These openings must be unobstructed to assure an adequate flow of cooling air around the firebox. If the fireplace is equipped with a blower, or may be equipped with one at a later date, the hearth extension must not prevent the removal of the lower louver panel for servicing the blower. Plan adequately by determining the finished height of the hearth extension to be used and elevate the fireplace on a platform, if necessary, to prevent obstructing the air openings or lower louvered panel. FIGURE 11 The ability of insulating material to retard the transfer of heat may be expressed as either Thermal Conductance (C), Thermal Conductivity (K), or Thermal Resistance (R). The mathematical relationship of these values and the formulas for converting one value to another is as follows: C = K divided by the material thickness (Example C = .43 divided by 1/2 (.50) C = .86) K = C multiplies by the material thickness (Example K = .86 multiplied by 1/2 (.50) K = .43) R = The material thickness divided by K (Example R = 1/2 (.50) divided by .43 R = 1.16) FIGURE 12 FIREPLACE HEARTH FLOOR 12" 20" METAL SAFETY STRIP WARNING: THE HEARTH EXTENSION AND..
