Figure 62: Installing Mounting Bracket.
Table 7 example, the differences are 1” (25mm) and 3” (76mm).
c)Mark the height difference on the left and right trim sides. Using the example, they would be marked 1” (25mm) from the bottom of each side, see dimension “A” in Figure 61.
d)Mark the center of the top trim, 155⁄8” (397mm) from either side. From the center line mark half the width distance on either side. Using the example of 3” (76mm), there would be marks 11⁄2” (38mm) on either side of the center line, see dimension “B/2” in Figure 61.
9.Fasten a mounting bracket to each of the four (4) mounting bracket backs using two (2) #8
10.Line the ends of the surround corners with the marks from step 8. Move the mounting brackets until the holes on the surround line up with the slots on the mounting brackets. When everything is lined up, secure the surround to the mounting brackets with eight (8) #8
