When installing your door you must use sections of the appropriate height in the right stacking order. What sections heights you need to use in what order depends on the height of your door.

Unless your door is five sections in height, you will not receive an Intermediate II section.

The bottom section can be identified by the factory attached bottom astragal and by the bottom bracket warning labels on each end stile.

The intermediate I section may have a warning label attached to either right or left hand end stile of the section. This section is always the 3rd section from the bottom of the door.

Removing an Existing Door

Important: Counterbalance spring tension must always be released before any attempt is made to start removing an existing door.

WARNING

A powerful spring releasing its energy suddenly can cause severe or fatal injury. To avoid injury, have a trained door systems tech- nician, using proper tools and instructions, release the spring tension.

For detailed information see supplemental instructions “Removing an Existing Door/ Preparing the Opening”. These instructions are not supplied with the door, but are available at no charge from Wayne-Dalton, A Division Of Overhead Door Corporation, P.O. Box 67, Mt. Hope, OH., 44660, or at www.Wayne-Dalton.com.

Preparing the Opening

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 center 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 at- tached 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 necessary) 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” 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.

Backroom requirement: Backroom is defined as the distance needed from the opening back into the garage to allow the door to open fully.
