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 Board

The H6 fi replace requires a 1/2" (13 mm) thick non-
combustible board or equivalent, to be used as a wall
surface immediately above the unit—see diagram for
minimum coverage.
Extending the non-combustible board well beyond
the minimum shown will help avoid cracking due to
diff erential expansion of materials.
Pre-drill non-combustible 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 non-combustible 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 1430FFK—Fixed Framing
Kit and the 1430CIK—Clean Install Kit.
All the other trims, 1435 and 1440v2 will accept wall
fi nish tucked behind their edge up to approximately
2" thick.
