Cement Board

LT1 2500K

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.

Min. 48” (1219 mm)

Min. 47-3/8” (1203 mm)

Flush with bottom of unit;

add extra cement board

if overlapping framing.

Minimum coverage area of non-combustible board.

Any wall nish applied to shaded area must be non-combustible.

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

Provide joints

either here or

here

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.
