FIREPLACE FRAMING
If unit is to be “built in”, fireplace framing can be built before or after the appliance is set in place. BE SURE THAT ALL
PACKING MATERIAL HAS BEEN REMOVED FROM THE UNDERSIDE OF THE UNIT PRIOR TO SETTING
THE FIREBOX IN PLACE. Construct fireplace framing following Figures 21 through 24. See Figure 2 on page 8 for
fireplace dimensions. 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 appropriate 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 fireplace 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.
