The SLR can be finished using either the Tonic or Martini decorative fronts. See Figures 13.17 and 13.18. Depending on the decorative front, the final fireplace installation can be accomplished by either the “overlap” or “inside-fit” method. Reference Section 13.C regarding installation details associated with the Inside and Overlap Fit methods.

If the final fireplace installation uses the Overlap Method, wall sheathing material ½” thick is specified and can be installed tight to the side finishing flanges. If the final fireplace installation uses the Inside-Fit Method, additional clearance of 4” must be maintained between combustible ½” thick wall sheathing material and the side finishing flanges. Reference Section 13.C regarding installation details associated with the Inside and Overlap Fit methods.

When finishing the wall around the fireplace, it is critical that wall sheathing be fastened properly. Wall sheathing fasteners, such as screws or nails, are not permitted in some locations. See Figure 13.4. It is acceptable to pre-drill holes and use self-tapped screws in the factory- installed non-combustible board which may be used to lathe (a backer for tile, marble, etc.) Screws being installed through the factory-installed non-combustible board should be self-tapping type with a minimum length of 5” and maximum length of 7”. It is also acceptable to penetrate the top flange with self-tapping screws. See Figure 13.4. Do not drill or install screws into the side columns as the existing stand-offs will support the wall sheathing. Do not drill or install screws which may penetrate the lower cover panel as this will restrict required access to the glass, battery-back-up, and remote receiver. See Figure 13.4.

The appliance is designed to accept ½” wall sheathing materials such as drywall, plywood, wood composites, or non-combustible materials. The type of material used depends whether the installation is an Inside or Overlap Fit method. Reference Section 13.C regarding installation details associated with the Inside an Overlap Fit methods. The left/right sides and bottom of the fireplace opening include finishing flanges that will interlock with ½” wall sheathing. See Figure 13.4. The ½” thick wall sheathing can be installed tight to the left, right, and bottom finishing flanges such that the rough edges of the sheathing are tucked behind the flanges. See Figure 13.5. It is necessary to cut a ½” slot in the sheathing where it is tucked tightly behind the lower finishing flange. See Figure 13.7.

Verify that the lover cover panel is installed correctly, and that the fireplace opening height is 16 in. See Figure 13.6.

NOTE: It is acceptable to use a high temperature sili- cone sealant to adhere drywall to lower cover panel.
