Two-Ring Door Installation
Before beginning the installation, be sure the correct door has been received.
Figure 1A
1.Remove inner door panels and outer door cover. Apply two rows of rope caulk around all four (4) door flanges: On vertical flanges, one row of caulk should be applied between the two vertical rows of bolts and the other row of caulk should be applied between the door frame and the first row of vertical bolts. On the horizontal flanges, a row of caulk should be applied on each side of the row of bolts.
NOTE: For the 2.66" corrugation, all caulk is applied to the outside of the door flanges and the door flanges are applied to the inside of the sidewall.
NOTE: For 4.00" corrugation: the top of the door frame goes to the inside of the sidewall and the bottom of the door frame goes to the outside of the sidewall. Therefore, depending upon location and overlap, caulk will be applied on either the inside or the outside of the door flanges. See Figure 1A for illustration.
With inner door panels and outer door cover removed, set door frame into opening. Insert several bolts at four (4) corners of door frame and sidewall, do not tighten until completing Step #2.
2.Reinstall inner door panels at original locations. Close latch bars to lock panels in place. Be sure that panels are fully seated over all bearing pins. Install inner panel hinge assemblies per instructions in manual
3.To make panels easier to operate, loads on pins should be uniform. To do this, loosen all bearing pin bolts with inner panels latched. Then, retighten all bearing pin bolts.
