Mounting Wall Switch to Side of Mantel
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.
5. Be certain that all wire terminals are
securely attached to terminals on
blower motor and that the screw retain-
ing the green ground wire is tight.
