screws, at the top right and left corners of the fire-

Align the short brackets so the edge of the bracket
is exactly aligned with the side edge of the fireplace

the location of the holes using a pencil mark through
the bracket holes. Drill 1/8” holes at each of the four
(4) locations. Mount brackets using four (4) sheet
