Replacement Procedures
Step 1: Bonnet Removal
A. IF GAS SERVICE HAS NOT BEEN DISCONNECTED:
1. Turn handwheel counterclockwise to fully open and backseat
the lower stem.
2. Hold the lower portion of the dual bonnet in place with a
3
⁄4" end
wrench. Without turning the handwheel, use a second 1
1
⁄16" end
wrench to remove the upper stem assembly by turning the bonnet cap
counterclockwise (see Fig. 1). Destroy the old assembly so it cannot
be reused.
B. IF GAS SERVICE HAS BEEN DISCONNECTED:
1. The valve is in the closed position.
2. Turn handwheel counterclockwise to fully open and backseat
the lower stem.
3. See A-2 above.
Step 2: Re-Assembly:
1. Place the new handwheel, bonnet, and stem assembly in the lower portion
of Ihe dual bonnet. Make the new assembly finger-tight by engaging the
bonnet cap two or three threads.
2. Rotate the handwheel counterclockwise while pushing down on the
handwheel until you feel the upper stem engage the lower stem.
3. Tighten the bonnet cap clockwise with 50 to 70 inch-pounds of torque.
Step 3: Testing
1. Turn the handwheel approximately a half turn towards the closed position.
DO NOT FULLY CLOSE THE HANDWHEEL AS THIS WILL SHUT OFF THE
GAS AND INTERRUPT THE SERVICE. Note if there is any binding or
grinding. Replace the assembly.
2. Check the bonnets and stem connections for leaks, using a mild
ammonia-free soap-and-water solution or an approved commercial-leak
solution. If no leak occurs, turn the handwheel counterclockwise to fully
open and backseat the lower stem.
