Plan Wall Finish
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 Fixed
Framing Kit 1130.
All the other trims, 1135, 1140, 1147 and 1149
will accept wall fi nish tucked under their edge up
to approximately 2" thick.
