Filler-Section Replacement Procedures
Step 1: Disassembly
1. Remove all traces of LP gas from the cylinder using the procedures
specified in National Fire Protection Association Pamphlet #58
and National Propane Gas Association Installation and Service Guide
Book #4403.
2. Clean the valve with clean compressed air so dirt does not enter
the valve interior.
3. Remove the valve cap. Remove the O-ring inside the ACME connector.
Destroy the O-ring so it cannot be reused.
4. Using Tool #TL623B (
7
⁄8" hex), remove the retainer from the valve by
turning it counter-clockwise with a
7
⁄8" wrench. NOTE: The retainer is
completely inside the body.
5. Remove the seal retainer.
Step 2: Inspection
1. Inspect the threads on the retainer and in the body. If any are damaged
or worn, replace the retainer or replace the complete valve if damage is
evident in the body.
Step 3: Re-Assembly
1. Place the seal into the white seal retainer.
2. Place the seal retainer assembly into the top of the valve body
so that the black seal is facing down and the white seal retainer
is facing up. Note: The seal retainer assembly must rest flat on top
of the poppet assembly.
3. Hand-tighten the threaded brass retainer into the top of the valve body
until it stops.
4. Use a torque wrench with a
7
⁄8" socket and Tool #TL623B, tighten to 20
(±5) foot-pounds.
5. Install a new G216B O-ring into the groove in the valve body.
Step 4: Testing
1. Pressurize the system with LP gas at 50 to 150 psig (30 to 90° F).
Using a commercial leak-test solution, check for leaks. As a precaution,
check the valve-to-tank connection as well.
2. Keep your body away from the valve inlet. Carefully place two or three
drops of commercial leak-test solution around the poppet seal and
inspect for leaks. When complete, use a clean cloth or paper towel to
remove the excess liquid. Do not use a soap-and-water solution for
this test. It could corrode the internal parts.
3. If any leaks are found, evacuate the tank according to NFPA
Pamphlet #58 and NPGA Installation and Service Guide Book #4003.
Remove and destroy the entire valve so it cannot be reused. Install a
new valve.
4. If no leaks are found, the valve may now be placed in ervice.
Make sure the valve cap is in place and tightened.
