Step 7. Once the door is away from the jamb, lift door off the closer shaft. Set door aside in a safe place. For this installation, the door was placed onto two sawhorses at a workable height.
Once door has been removed, check the arm and the floor closer. Check the bottom of the door to be certain the closer arm bolts are tight. Also consider checking if the closer is leaking. Service as necessary.
Step 8. Install the mounting blocks into the top of the stile.
Step 9. Place the top latch into the stile of the door. Mark the location for the latch bolt trigger notch. As the door closes, the latch bolt trigger contacts the jamb stop and releases the latch bolt, which extends into the strike, latching the door closed.
Step 10. Cut the 5/8" deep by 3/8" wide notch into the vertical centerline of the stile to accommodate the latch bolt trigger.
Step 11. Locate the exit device modified plate onto the inside of the door.
Step 12. Drill the four 5/16" diameter mounting holes for the center case and the trim. The device mounting holes are on the center line for the rods. The two holes closest to the swing side of the door edge secure the center case to the trim.
Step 13. Cut the yoke pin slot in the interior side of the stile. The yoke pin slides up and down to latch and unlatch the mechanism.
Step 14. Attach the yoke pin onto the arm and bracket assembly.
Step 15. Lay the latch on top of the stile and mount the top rod and arm and bracket assembly to determine the proper length for the top rod. Adjustment holes in the top rod are six inches apart with the longest standard length for an eight foot door. If necessary, cut the top rod to accommodate the door height using a hacksaw.
Step 16. Assemble the latch, top rod, and arm & bracket assembly. Install the cotter pin securing the tube to the rod.
Step 17. Install the two cotter pins securing the rod to the arm and bracket assembly.
Step 18. Slide the entire assembly into the stile of the door with the latch bolt contacting the mounting blocks.
Step 19. Position the yoke pin in the slot on the interior side of the door. With the latch bolt extended, the yoke pin should be lower on the stile without contacting the bottom edge of the slot. Retract the latch bolt and the yoke pin should rise up within the slot without contacting the top edge of the slot. If the yoke pin contacts an edge of the slot, adjust the length of the rod. Turning the rod in a clockwise direction lengthens of the rod. Turning the rod in a counterclockwise direction shortens the rod.
Step 20. Secure the latch to the mounting brackets using the six #10-24 x 1/2" Phillips head screws.
Step 21. Slide the center case over the slot, having the yoke pin slide into the opening. Install the E-Clip to attach the yoke pin to the armature. Test the operation of the exit device.
Step 22. Install the rim cylinder into the trim. Make sure the clutch lever moves up and down to control the operation of the trim.
Step 23. Install the trim and the center case onto the door using the #1/4-20 Phillips head screws. The two screws that secure the center case to the trim slide through the opening in the arm and bracket assembly. Use the provided finishing washers for the two screws that mount directly onto the stile.
Step 24. Test the operation of the exit device and trim.
The two Yale 7160 Concealed Vertical rod Exit devices and 626F trims provide a clean installation with no exposed mechanisms. By eliminating the mullion, this pair of doors has increased the traffic flow capability.
