INSTALLATION PLANNING
WALL FINISH
Non-combustible cement board
. The CL2118 appliance requires a 1/2” (13 mm) thick non-combustible
cement board to be used as a wall surface immediately surrounding the unit on each side (see
Fig.13
below)
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.
Non-combustible finishing over cement board
. Additional non-combustible material such as tile, etc., may
be applied over top of the cement board or you may choose to leave it finished clean with no tile—see next
page. Be aware that a trim is always required and the trims will accept tile, etc. behind them up to 1” thick,
depending on appliance side flange position. Additional non-combustible finishes, if desired, may be butted up
to the trims. Finish should not cover the trims as they need to remain removable.
