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 differential 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, etc.
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
Minimal 1130 clean style trim.
All the other trims, 1135, 1140, 1147 and 1149
will accept wall
fi
nish tucked under their edge up
to approximately 2” thick.
