The enclosure walls can be framed with any suitable materials (2"x 4"or 2" x 6" studs, plywood, gypsum board, etc.). Because
of the high heat output potential of the CF780, combustible materials must NOT be used on the entire front of the unit. Use
only steel studs, non-combustible board,and non-combustible materials.
Fireplace Facing
The CF780 MUST be covered with at least ½” cement board panels such as James Hardie HardieBacker® or USG Durock®
cement boards. Either product will allow you to finish the facing of the fireplace with any non-combustible material you like.
Warning:
Do not use gypsum boards on the face of the fireplace.
Covering the Fireplace Facing
Facing materials must be NON-COMBUSTIBLE such as metal, brick, slate or ceramic tile. Gypsum board is NOT an accept-
able facing material. The only combustible material accepted on the facing of the fireplace is for a mantel (shelf and posts).
Optional Furring strips can be added to the front of the appliance if using thinner material to complete the install. This will
allow the front of the finished material to be flush with the front of the lintel to make it aesthetically pleasing.
Note: All non-combustible facing material should butt up cleanly to the flanges around the firebox opening.
Rough edges may be visible from an angle. To maintain a clean finished edge - facing material edges may be finished with a
metal J-style trim or metal corner bead (both materials available at your local building or hardware store).
The cement boards can be painted, textured or tiled just as you would over gypsum boards. The lintels pro-
vided with the fireplace are appropriate for thin facing materials. A wider steel lintel may be required for heavy
rock, stone, or brick. If so, contact your local sheet metal or masonry contractor for a custom steel lintel.
If you need to attach anything to the front of the fireplace make sure to close the guillotine door and firescreen before at-
tempting to do so. Refer to Diagram 18 to know where you are allowed to screw. Use screws that penetrate by no more than
¾” the front surface of the cement boards.
Any deeper penetration of the screw tip or placing the screws anywhere else will either prevent the proper operation of the
firescreen and/or the guillotine door, or eventually cause difficulty dismantling the guillotine system.
CAUTION: IF ABSOLUTELY NECESSARY, YOU CAN SCREW
INTO THE CEMENT FACING ELSEWHERE AS LONG AS THE
SCREW TIP DOES NOT COMPLETELY PENETRATE THE 1/2’’
CEMENT BOARD PANELS.
