following . The framing headers may rest directly on top of the firebox.
The fireplace may be installed directly on a combustible floor or a raised platform of an appro-
priate height. Do not place fireplace on carpeting, vinyl, tile or other soft floor coverings. It may,
however, be placed on flat wood, plywood, particle board or other hard surfaces. Be sure fire-
place rests on a solid continuous floor or platform with appropriate framing for support and so
that no cold air can enter from under the firebox.
Anchor fireplace to the side framing members using nailing flanges.
