|
| 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 | |
|
| bearing brackets, or steel angles to new or | |
|
| 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 14” (356 mm) above the | |
|
| top of the opening for Torsion spring applications. For low headroom | |
|
| applications, the jambs should extend to the ceiling height. Minimum | |
|
| side clearance required, from the opening to the wall, is | |
|
| mm). | |
|
| IMPORTANT: Closely inspect existing jambs, header and | |
|
| mounting surface. Any wood found not to be sound, must be | |
|
| replaced. | |
|
| For Torsion spring applications, a suitable mounting surface must | |
|
| be firmly attached to the wall, above the header at the center | |
|
| of the opening. The mounting surface must be 2” x 6” lumber | |
|
| minimum (Select southern yellow pine lumber. Do not use lumber | |
|
| marked as | |
|
| securely attached to the wall with four (4) 3/8” anchors for masonry | |
|
| constructions or four (4) 5/16” x 4” lag screws for wood construction. | |
|
| NOTE: Drill a 3/16” pilot hole in the mounting surface to avoid splitting | |
|
| the lumber. Do not attach the mounting surface with nails. | |
|
| Weather Seal (May Not Be Included): | |
|
| Cut the weather seal if necessary to fit the header and jambs. | |
|
| Align the header seal with the inside edge of the header and | |
|
| temporarily secure it to the header with equally spaced nails. Next, | |
|
| fit the jamb seals up tight against the header seal and flush with the | |
|
| inside edge of the jamb. Temporarily secure the jamb seals with equally | |
|
| space nails approximately 12” to 18” apart. This will keep the bottom | |
|
| section from falling out of the opening during installation. | |
|
| NOTE: Do not permanently attach weather seal to the jamb at this time. | |
|
| 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, | |
|
| 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. |
