Fire Risk

•Hearth extensions must be installed exactly as specified.

High temperatures or hot embers may ignite concealed combustibles.

•Thermal conductivity per inch thickness = k

•k = (BTU)(inch) / (foot2)(hour)(°F)

•Required thickness = Rk

•Thermal resistance per inch thickness = r

•r = (foot2)(hour)(°F) / (BTU)(inch)

•Required thickness = R / rB.
