Failure to maintain stated minimum clearances may result in a fire or explosion, causing property damage, personal injury, or
loss of life.
Do not pack required air spaces with insulation or other materials. Using insulation or other materials in required air spaces
may result in a fire or explosion, causing property damage, personal injury, or loss of life.
NOTE
: “Combustibles” are defined as “normal construction materials” and are considered to be: wood framing materials, particle
board, mill board, plywood sub-flooring, plywood paneling, wood flooring, and drywall.
The fireplace must sit on a concrete pad or slab that is designed to bear the total weight of the fireplace and chimney. This pad
or slab should provide for the noncombustible hearth extension substrate needed to support the code required noncombustible
hearth extension finish materials.
This product is designed to be either freestanding or, in the event additional dimension is required, built out with concrete
masonry units (CMUs) or metal framing material. There is no airspace or clearance distance to CMUs or metal framing material
required.
All fireplaces should have a noncombustible hearth that extends 20” beyond the front of the firebox and 8” to either side.
Approved noncombustible materials include brick, tile, or stone that is properly supported, with no combustible material against
the underside.
