Material Speci
fi
cations
Non-Combustible
Material which will not ignite and burn. Such materials
are those consisting entirely of steel, iron, brick, tile,
concrete, slate, glass or plasters, or any combination
thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750°C shall be considered
non-combustible materials.
Combustible
Materials made of or surfaced with wood, compressed
paper, plant
fi
bers, plastics, or other material that
can ignite and burn, whether
fl
ame proofed or not,
or plastered or unplastered shall be considered
combustible materials.
Non-Combustible Cement Board
The LT2 Linear
fi
replace requires a 1/2” (13
mm) thick
non-combustible cement board to be used as a wall
surface immediately surrounding the unit’s opening—
see diagram for minimum coverage.
Extending the cement board well beyond the minimum
shown will help avoid cracking due to di
ff
erential
expansion of materials.
Pre-drill cement board with oversized holes and do
not over-tighten screws to avoid cracking due to heat
expansion.
Standard gypsum wall board may be used beyond the
perimeter of the cement board.
