Plan Wall Finish - Valor 1500IN Installation & Owner's Manual

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.
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.
