Process 3 – Door Jamb and Door Header Assembly
Step 1 - Installation of Door Jambs on Frontal Panel. Reference Figure 7 a) To install the door jambs to the panels first the male channel of the insulated panel must have strip insulation installed. b) Install the door jamb until the male channel is completely inside the door jamb. c) Fasten the door jamb to the panel using the provided stitch screws starting on one end and working towards the other. Do this process for both sides of the door jamb. Step 2 - Installation of Door Header a) Before lifting the door h e ader into place, make a mark on the door jamb for the location of the bottom of the door jamb. This measurement can be retrieved from the drawing packet provided. > A small piece of angle can be temporarily tack welded into place at this location to aid in the installation of the door header by creating a ledge for it to rest. b) When door he ader has been lift ed into place make sure that the front of the door header is flush to the outside of the door jamb. Reference Figure 7. c) Tack the door header in place (DO NOT weld solid) d) Check door framing for square and plumb. Reference Figure 8. e) Once square and plumb weld the door header in solid making sure the opening stays square and plumb.
NOTE: Adjustments made with the door header to create a square opening may not actually be enough. It may be necessary to use spacers under the door jambs in order to square the opening. This is only necessary if the cement floor is not level across the width of the opening.
Step 3 - Installation of T-7 to Door Header (Ovens WITHOUT Internal Structure) a) Once door header has been mounted attach the T-7 trim to top inside of the door header. Reference Figure 9 and Figure 10.
