Place a large pipe wrench in position on the door axle as shown and slightly
loosen both axle saddle castings. Pull down on the wrench for more spring
tension and let up on the wrench for less spring tension.
As saddle castings are
loosened, hold wrench securely.
Springs are very strong and can
cause serious injury if not controlled properly.
Tighten both axle saddle castings per Step #6 while holding the pipe wrench
firmly to maintain desired adjustment. Let off the pipe wrench tension only
after the nuts on both axle saddle castings are tightened back to 40 foot-pounds.
When removing pipe wrench from axle, slowly reduce applied
tension until wrench is free from axle. This will help avoid
serious injury in event that saddle castings have not been
tightened sufficiently.
Test the door as in Step #9 above. Repeat the above procedure if further adjustments are required. Once all
adjustments have been made and the door is operating properly, recheck all fasteners and bolted connections to
ensure that they are in place and properly tightened. Tighten all set screws in the components installed in step #4.
STEP 11 INSTALLATION OF TOP DRAFT STOP
Close the door and secure it in the down
position. Use a pencil to mark the door panel
corrugation that is parallel with the bottom of
the header/lintel from the outside of the
opening. If this corrugation protrudes below the
header, mark the one just above. Open the door
until the marked corrugation is accessible.
Stretch the top draft stop across the door and
attach it to the curtain on the marked
corrugation with the #8 x ½” self-drilling
screws provided, locating the screws every 12"
on center. Trim the Top Draft Stop to clear the
guides if required. When the door is closed, the
draft-stop should seal on the header.
Top Draft Stop may not seal on header if not installed on a corrugation as
shown.
