To avoid possible injury and to insure proper installation, it's highly recommended that you
read and fully understand the complete instructions on removing an Existing Door & Prepar-
ing the Opening. These are available for download at www.Wayne-Dalton.com or at your
local Wayne Dalton Sales Center.
IMPORTANT: IF YOU JUST REMOVED YOUR EXISTING DOOR OR YOU ARE INSTALLING A
NEW DOOR, COMPLETE ALL STEPS IN PREPARING THE OPENING.
To ensure secure mounting of track brackets, side and spring anchor brackets, or steel
angles to new or retro-fit construction, it is recommended to follow the procedures outlined in
DASMA technical data sheets #156, #161 and #164 at www.dasma.com.
The inside perimeter of your garage door opening should be framed with wood jamb
and header material. The jambs and header must be securely fastened to sound framing
members. It is recommended that 2” x 6” lumber be used. The jambs must be plumb and
the header level. The jambs should extend a minimum of 12” (305 mm) above the top of
the opening for Torsion counterbalance systems. For low headroom applications, the jambs
should extend to the ceiling height. Minimum side clearance required, from the opening to
the wall, is 3-1/2” (89 mm).
IMPORTANT: CLOSELY INSPECT JAMBS, HEADER AND MOUNTING SURFACE. ANY WOOD
FOUND NOT TO BE SOUND, MUST BE REPLACED.
For Torsion counterbalance systems, a suitable mounting surface (2” x 6”) must be firmly
attached to the wall, above the header at the center of the opening.
NOTE: Drill a 3/16” pilot hole in the mounting surface to avoid splitting the lumber. Do not
attach the mounting surface with nails.
WEATHERSTRIPS (MAY NOT BE INCLUDED):
Depending on the size of your door, you may have to cut or trim the weatherstrips (if neces-
sary) to properly fit into the header and jambs.
NOTE: If nailing product at 40°F or below, pre-drilling is required.
NOTE: Do not permanently attach weatherstrips to the header and jambs at this time.
For the header, align the weatherstrip 1/8” to 1/4” inside the header edge, and temporarily
secure it to the header with equally spaced nails. Starting at either side of the jamb, fit the
weatherstrip up tight against the temporarily attached weatherstrip in the header and 1/8”

Pre-Installation

to 1/4” inside the jamb edge. Temporarily secure the weatherstrip with equally spaced nails.
Repeat for other side. This will keep the bottom section from falling out of the opening during
installation. Equally space nails approximately 12” to 18” apart.
HEADROOM REQUIREMENT: Headroom is defined as the space needed above the top of
the door for tracks, springs, etc. to allow the door to open properly. If the door is to be motor
operated, 2-1/2” (64 mm) of additional headroom is required.
NOTE: 6” low headroom conversion kit is available for 12” radius only. Contact your local
Wayne Dalton dealer.
BACKROOM REQUIREMENT: Backroom is defined as the distance needed from the opening
back into the garage to allow the door to open fully.
*NOTE: For door heights from 10’1” to 14’0”, refer to your operator manufacture installation
instructions for appropriate depth into room.

Door Section Identification
When installing your door, you must use sections of the appropriate height in the right stack-
ing location. Determine, what sections you need to use in what order depends on the design
of your door.
Sections are stamped for identification, #1, #2, #3, and #4 (#4 only on four section high
doors). The stamp, located on each side of the sections identifies the stacking sequence. The
sequence is always determined by #1 being the bottom section to #3 or #4 being the highest
top section. If the stamp on the section is illegible, refer to the section side view illustration.
The section side view illustration shows the section profile of all sections, and can also be
used to identify each section.
The BOTTOM SECTION can be identified by #1.
The INTERMEDIATE I SECTION can be identified by #2.
The INTERMEDIATE II SECTION can be identified by #3, for a 4 section high door only.
The TOP SECTION can be identified either by a #3, for a 3 section high door or by a #4, for
a 4 section high door.

DOOR INSTALLATION
INSTRUCTIONS
Before installing your door, be certain that you have read and followed all of the instruc-
tions covered in the pre-installation section of this manual. Failure to do so may result in an
improperly installed door.
NOTE: Reference TDS 160 for general garage door terminology at www.dasma.com.
IMPORTANT: WOOD DOORS MUST BE COMPLETELY FINISHED (3 TOTAL COATS, INCLUDING
PRIMER COAT) PRIOR TO INSTALLATION, TO ENSURE THAT THE INTERIOR AND EXTERIOR
SURFACES, AS WELL AS ALL EDGES OF THE DOORS ARE PROPERLY PROTECTED AGAINST
MOISTURE OR OTHER CONTAMINANTS. WOOD DOORS, IN A NON-FINISHED CONDITION,
MUST BE TRANSPORTED AND STORED SO THE WOOD SURFACES ARE NOT EXPOSED
TO MOISTURE OR OTHER CONTAMINANTS. IMPROPER TRANSPORTATION, STORAGE OR
DELAYS IN FINISHING, THAT ALLOWS EXPOSURE OF THE WOOD DOOR SURFACES TO MOIS-
TURE OR OTHER CONTAMINANTS WILL RESULT IN THE WARRANTY BEING VOIDED.
