PLANNING

Identify the type and height of your garage door. Survey your garage area to see if
any of the conditions below apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this page and the accompanying
illustrations as you proceed with the installation of your opener. Depending on
your requirements, there are several installation steps which may call for
materials or hardware not included in the carton.
Installation Step 1 – Look at the wall or ceiling above the garage door.
l
The header bracket must be securely fastened to structural supports.
Installation Step 5 – Do you have a finished ceiling in your garage? If
l
so, a support bracket and additional fastening hardware may be
required.
Installation Step 12 – Depending upon garage construction, extension
l
brackets or wood blocks may be needed to install sensors.
Installation Step 12 – Alternate floor mounting of the safety reversing
l
sensor will require hardware not provided.
Do you have an access door in addition to the garage door? If not, an
l
emergency key release is required.

Look at the garage door where it meets the floor. Any gap between the
floor and the bottom of the door must not exceed 1/4" (6 mm).
Otherwise, the safety reversal system may not work properly. See
Adjustment Step 2. Floor or door should be repaired.
Do you have a steel, aluminum, fiberglass or glass panel door? If so,
horizontal and vertical reinforcement is required (Installation Step 8).
The opener should be installed above the center of the door. If there is a
torsion spring or center bearing plate in the way of the header bracket, it
may be installed within 4 feet (1.22 m) to the left or right of the door
center. See Installation Steps 1 and 8.
If your door is more than 7 feet (2.13 m) high, see rail extension kits
listed on Accessories page.
FINISHED CEILING
Support bracket &
fastening hardware
is required.
