from ground may vary depending on local codes or location.
Make sure that no wall studs, pipes or wires run through
the opening area.
2. From inside, mark and drill a guide hole at the center of
the opening area.
3. From the outside, use the guide hoel as a starting point to
lay out the installation.
A. Use a T-square to measure 11
13/16
” (30.0 cm) to the
left of the guide hole, then 14
11/16
” (37.3 cm)
tolocate the top-left corner of the layout.
B. Starting from the top-left corner, mark a 22” (55.9
cm) by 29
1/2
” (74.9 cm) rectangle on wall located
from guide hole.
4. Cut a rectangular hole in the siding only. Do not cut the
sheathing. Nail down all siding ends.
5. Mark an 11” (27.9 cm) diameter circle centered on the
guide hole and mark the center of the 1
1/4
” diameter
electrical wiring hole.
6. Cut the 11” (27.9 cm) hole in the sheathing and drill the
1
