ROD ADJUSTMENT PROCEDURE
1690 Series rods are preset at the factory. However, in some cases the rods may require adjustment.
The general rod adjustment procedure is to adjust the top rod first and then the bottom rod.
1690 TOP ROD ADJUSTMENT
1. With the 1690 device installed and rods in the door, remove the active cover.
2. Dog the device. If it dogs and undogs freely go to Step 3. If it does not, the top rod is too long.
To determine how much to shorten the rod:
A. Undog the device.
B. Hold the top rod all the way up and push the lift arm to the bottom of its travel with the push bar completely out.
C. Measure the distance between the bottom of the traveler projection and the top of the lift arm roller (
See Detail "F").
D. Subtract the distance from 1/2".
E. Using the difference from
Step D, find the number of turns to shorten the top rod from the "Rod Adjustment Table" shown below.
F. Remove the top rod and shorten it by the required number of turns. Reinstall the top rod.
3. Dog the device and push the traveler against the lift arm while maintaining pressure on the traveler. Attempt to pivot the top latch bolt
(
See Detail "G"). If the top latch bolt pivots freely, go to Step 4. If the top latch bolt drags or lifts the top rod, the top rod is too short.
To determine how much to lengthen the top rod:
A. Push the traveler all the way down then slowly lifting it away from the lift arm until the top latch bolt moves freely.
B. Measure the distance between the bottom of the traveler projection and the top of the lift arm roller (
See Detail "F").
C. Using the measured distance, find the number of turns to lengthen the top rod from the "
Rod Adjustment Table".
D. Remove the top rod and lengthen it by the required number of turns. Reinstall the top rod.
1690 BOTTOM ROD ADJUSTMENT
4. Undog the device and push down firmly on the lift arm and end of the bottom rod (be sure the push bar is all the way out).
Find the location of the bottom rod to the bottom of the door. Make sure you measure from the bottom of the door, NOT from the latch housing.
If the bottom rod is flush with the door or sticks out from the door no more than 1/32", go to
Step 7.
5. If the bottom rod sticks out more than 1/32", the bottom rod is too long.
To determine how much to shorten the bottom rod:
A. Measure the distance that the bottom rod sticks out of the door and look up the number of turns required to shorten the bottom rod in the
"
Rod Adjustment Table".
B. Remove the bottom rod, shorten it by the required number of turns, reinstall bottom rod.
6. If the bottom rod is recessed into the door by more than 1/16", the bottom rod is too short.
To determine how much to lengthen the bottom rod:
A. Measure the distance that the bottom rod is recessed into the door and look up the number of turns required to lengthen the bottom rod in
the "
Rod Adjustment Table".
B. Remove the bottom rod, lengthen it by the required number of turns, reinstall bottom rod.
OPERATIONAL CHECK
7. Dog the device. The top latch bolt should pivot freely and the bottom latch bolt should be flush with the bottom of the door.
8. Undog the device and trip the top latch bolt. The top latch bolt should stay latched and the bottom bolt should extend at least 7/16" to 1/2" from the
bottom of the door.
