Plan Wall Finish

Non-combustible cement board
The L1 Linear 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 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 fi nishing 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 fi nished clean with no tile, etc.—see page
39. 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.
