Plan Wall Finish
Non-combustible cement board
The L1 Linear see-thru fi replace 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 diagram 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.
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 only
the 1555 and 1550 style trims will accept
tile, etc. tucked behind them (up to 5/8"
thick for the 1555 and up to 1 inch thick
for the 1550). Additional non-combustible
fi nishes, if desired, may be butted up to the
concrete trim 1570RCS. Finish should not
cover the trims.
