Monessen Hearth SWB400I instruction manual Floor Protection

FLOOR PROTECTION

If this fireplace is installed on a combustible floor, the floor area 16 inches in front of, and 8 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, a H1652 Hearth Extension Kit or a locally constructed hearth equivalent to the H1652.

The insulation used in the H1652 hearth extension has a thermal conductivity (K Factor) of .43. If you do construct a hearth extension equivalent to the H1652, 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 to or better than the ˚" covering provided by the H1652.
