FLOOR PROTECTION
If this fireplace is installed on a combustible floor, the floor area 20 inches in front of, and 12 inches either side
of the fireplace opening must be protected by an insulating noncombustible hearth extension. 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.
