Foundation Requirements
Wood floor framing systems are suitable foundations
for the Vent-Free fireplace. Because the Vent-Free fireplace is
listed for “zero clearance” at the unit bottom, sides, back and
top it may sit directly upon wood sub-flooring.
The Vent-Free fireplace weighs approximately 750-
900 lbs. (excluding gas log appliance and finish trim). Since
this weight is spread over an area of seven and one-half square
feet (7.5 sq. feet) to nine and one half square feet (9.5 sq. feet)
depending on standard unit size chosen, it is necessary that any
wood floor framing where this unit is placed be designed to
carry concentrated loading of approximately 150 lbs/sq. foot.
Standard residential concrete slab is a suitable
foundation. This may be either a structural off-grade slab or a
structural slab-on-grade.
