Installation (continued)
Door Seal Adjustment
If instaling a double door, resume the procedure at this point after the doors been assembled
according to the instructions in 270A837.
If necessary, the sweep seal can be adjusted to ensure proper fit and to prevent sound leaks.
1. Open the door and loosen the four screws holding the sweep seal to the inner face of the door.
2. Move the sweep seal all of the way up in the slots and close the door slowly.
3. Slide the sweep seal down to contact the sill coverplate and tighten the screws.
If the sweep seal will not move, tap the screws with a mallet.
4. Check the gap between the sweep seal and the sill coverplate by sliding a sheet
of paper between the seal and coverplate. The paper should meet slight resistance all
along the seal. If it slides in without resistance, loosen the screw in that area,
move the seal down and retighten the screw. If there is too much resistance,
loosen the screw in that area, raise the seal slightly and re-tighten the screw.
5. As a further check, shine a flashlight or other bright light along the sweep seal
on one side of the door and look for light shining through on the other side.
No light should be visible through the sweep seal area. Adjust as necessary.
6. Use a piece of paper to verify that the foam compression seal on the leaf is in
continuous contact with the face of the door frame. If necessary, limited corrections
can be made by racking the door leaf.
(Operate the door several times to make sure these corrections are maintained).
Larger gaps can be corrected by loosening
the five cap screws holding the
leaf to the frame and slightly adjusting the
3/4" (19 mm) dimension between the
hinge barrels and the frame face
at the top or bottom of the leaf.
(Be careful to maintain the 1/8" (3 mm)
leaf elevation dimension).
