Fireplace Framing - Martin VENT-FREE FIREPLACE SYSTEMS 33ISDG Installation And Operating Instructions Manual

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
11 through 14. See Figure 6 on page 11 for fireplace
dimensions. The framing headers may not 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.
