Material Specications
Non-Combustible
Material which will not ignite and burn. Such materials
are those consisting entirely of steel, iron, brick, tile,
concrete, slate, glass or plasters, or any combination
thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750°C shall be considered
non-combustible materials.
Combustible
Materials made of or surfaced with wood, compressed
paper, plant fibers, plastics, or other material that
can ignite and burn, whether flame proofed or not,
or plastered or unplastered shall be considered
combustible materials.
Non-Combustible Cement Board
The LT1 Linear fireplace requires a 1/2” (13mm) thick
non-combustible cement board to be used as a wall
surface immediately surrounding the unit’s opening—
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.

LT1 2500K
Non-Combustible Finishing Over Non-
Combustible Board
Additional material such as tile, etc., may be
applied over top of the non-combustible board
or you may choose to leave it finished clean
with no tile, etc.
Be aware that a trim is always required. Finish
should not cover the trims.
2575 Trim
Only the 2575 style trim will accept tile, etc.
tucked behind it (up to 5/8” thick for the 2575).
2530 Trim
2530 trim must be installed BEFORE non-
combustible board. Non-combustible board
and finishes are applied to the perimeter of the
trim frame. Non-combustible board and finish
CANNOT be tucked under this trim.
Clean Installation Kit (2530) does not adjust
forward. Non-combustible board finishes
up to perimeter of the trim. Must be
installed before finish.
Narrow trim (2575) can adjust up to 5/8”
forward of surface of non-combustible
board

Wall Finish — Avoid Cracking

Cracks

Avoiding Cracking Wall Finishes
If a clean finish with no tile, etc. is desired, joints in the
non-combustible board and the transition to gypsum
board will require special attention if future cracking
is to be controlled. Be aware that temperatures on the
non-combustible wall surface above the appliance can
exceed 200°F (93°C).
Below are some tips on how to best avoid any cracking:
• Allow materials to dry thoroughly before finishing the
wall. Non-combustible board has the ability to absorb
up to 30 percent of its weight in water and may shrink
as much as 1/8” over a 48” length when drying from
a saturated condition. Running the fireplace for an
extended period before final finishing will help drive
out moisture.
• Always pre-drill screw holes through non-combustible
board and use screws with self-milling head.
• Always use mesh tape over joints.
• Always stagger joints in wall board.
• Behind joints, double up studs or use studs “on the
flat” to add extra support to the joint. Adhesive on
the backside of wall board behind any joints can help
control differential movement.
• Use multiple, thinner coats of joint compound and al-
low to dry thoroughly between coats.
• Ensure framing materials are dry.
• After finishing the wall, introduce heat gradually to
slowly dry any excess moisture rather than drying too
fast.
• Avoid notching non-combustible board or tiles around
corners of window opening and instead provide a joint
that intersects the corner.
• Avoid using lage one-piece slab of material with a
cut-out in the middle as a surround for the fireplace.
Expansion above the opening will cause cracking at
inside corners. Provide a joint that intersects the inside
corner to avoid cracking.
WARNING
HeatShift System MUST be installed on
this appliance.
