7.Create three openings in the mantel wall according to Template 2, page 35. This is best done by making a pattern to work with on the mantel. Carefully cut page 35/36 from manual and tape paper tem- plate vertically onto mantel wall at pre- ferred location. Pierce the paper at the centers of the 2 holes with a nail or sharp pencil, leaving a mark on the wall. Do the same at centers of the four circles near the corners of the rectangle.

8.Remove paper template from mantel wall.

9.Drill 1/8" pilot holes at each mark for top and bottom screw holes. Drill 3/8" holes at each mark for centers of four circles near corners of rectangle.

10.Using a straight edge and pencil, con- nect the outer edges of the 4 holes for the rectangle (see Figure 10, page 9). This will give you cutting lines for the rectangle you will cut in the mantel wall.

11.Using a keyhole saw, hack saw blade, drill, file, or other suitable tool, carefully cut out the rectangular opening. Note: The corners of the rectangle may be round. IMPORTANT: Do not exceed the size of the rectangle on template.

12.Carefully pass switch/plate assembly through rectangular opening from in- side mantel (see Figure 13).

13.Position switch/plate assembly vertically over opening with decal lettering upright. Make sure wires freely pass through wall without binding.Align holes in wall plate with 1/8" pilot holes in mantel wall.

14.Drive mounting screws, removed in step 2 of Relocating Wall Switch on page 9, through wall plate holes and into pilot holes in mantel wall.

15.Tighten screws until wall plate is firmly attached to mantel. Do not overtighten.
