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 9 through 12. Refer to Figure 2 on page 9 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 optional nailing flange kit. See installation instructions included 
with the kit.
