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. The header bracket must
be securely fastened to structural supports.
• Installation Step 4 - Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 4 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Installation Step 6 - Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
Do you have an access door in addition to the
garage door? If not, Model 53702 Emergency Key
Release is required. See Accessories page.
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 3. Floor or door should be
repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horiFontal and vertical
reinforcement is required (Installation Step 12).
• 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 12.
• If your door is more than 7 feet (2.13 m) high, see
rail extension kits listed on Accessories page.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door with
glass panels, etc.). See page 23 for details.
