Non-Combustible Materials Specifications
Non-combustible materials are those 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 Specifications
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 H5
fi
replace requires a 1/2” (13 mm) thick non-
combustible cement board or equivalent, to be used
as a wall surface immediately above the unit—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 although it is
preferable not to change materials to help avoid
cracking.
Finishing Around Trims
Additional non-combustible material such as tile, etc.,
may be applied over top of the wall surface or you
may choose to leave it
fi
nished clean with no tile.
Be aware that a trim is always required and that the
wall
fi
nish thickness must be taken into account for all
installations other than the 1130FFK—Fixed Framing
Kit and the 1130CIK—Clean Install Kit.
All the other trims, 1135, 1140v2 and 1184 will
accept wall
fi
nish tucked under their edge up to
approximately 2” thick.
