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 5 - Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• Installation Step 10 - Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 10 -Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.
Do you have an access door in addition to the
garage door? If not, Model 1702 Outside Quick
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, horizontal and vertical reinforce-
ment is required (Installation Step 11)
• 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 (122 m) to the left or
right of the door center See Installation Steps 1
and 11
• If your door is more than 7 feet (2,13 m) high, see
rail extension kits listed on Accessories page
