This is bestdone by making a pattern to work with on themantel. Carefully cut page 41/42 from manualand tape paper template vertically onto man-tel wall at preferred location. Pierce the paperat the centers of the 2 holes with a nail or sharppencil, leaving a mark on the wall. Do thesame at centers of the four circles near the cor-ners of the rectangle.8. Remove paper template from mantel wall.9. Drill 1/8" pilot holes at each mark for top andbottom screw holes. Drill 3/8" holes at eachmark for centers of four circles near cornersof rectangle.10. Using a straight edge and pencil, connect theouter edges of the 4 holes for the rectangle(see Figure 10, page 11). This will give youcutting lines for the rectangle you will cut inthe mantel wall.11. Using a keyhole saw, hack saw blade, drill, file,or other suitable tool, carefully cut out the rect-angular opening.Note: The corners of the rect-angle may be round.IMPORTANT: Do not ex-ceed the size of the rectangle on template.12. Carefully pass switch/plate assembly throughrectangular opening from inside mantel (seeFigure 13, page 11).13. Position switch/plate assembly vertically overopening with decal lettering upright. Makesure wires freely pass through wall withoutbinding. Align holes in wall plate with 1/8"pilot holes in mantel wall.14. Drive mounting screws, removed in step 2 ofRelocating Wall Switch on page 10, through wallplate holes and into pilot holes in mantel wall.15. Tighten screws until wall plate is firmly at-tached to mantel.
