LIFTING THE ENTIRE TRIM PACKAGE
10. The 3-way ball valves are factory-equipped with
positive stops to prevent over-rotation. In the event
these stops have been removed, do not over-rotate
the handle assembly as this may cause improper
valve operation. Slowly rotate the handle assembly
(key 48) of the 3-way valves until the handle
assembly points away from the newly installed pilot.
The handle assembly should be oriented such that
the sliding handle locks are capable of sliding into
place. Once the handle assembly points away from
the newly installed pilot, the new pilot should be
active and pressurized. Perform a leak check on all
connections and fittings.
a. At this time you may choose to continue using the
new pilot as the main control pilot or rotate the
handle assembly to utilize the alternate pilot as the
main control pilot.
11. The reserve pilot should be purged of pressure to
prolong service life and minimize the risk of vapor
reliquefying in the pilot and the piping. Gently
loosen the 11/16 in. compression fitting securing
the stainless steel line to the inactive pilot to bleed
off trapped pressure. After purging the inactive
pilot, finger tighten the compression fitting, then use
appropriate wrench to turn the nuts to 1/4 turn. Install
the wire seals.

The Main Valve Assembly can only be
repaired or modified where local codes or
restrictions allow. Check with your LP-Gas
distributor or local Authority Having
Jurisdiction for information on restrictions
that may apply.
Replacing Trim Sealing Parts
Perform this procedure if inspecting, cleaning or replacing
individual parts in the trim package, by using Repair
Kit Part No. R63EGLPX012. Key numbers for the
Type 63EGLP/63EGLP-16 Main Valve are referenced in
Figure 11.
All disassembly, trim sealing parts change
and reassembly steps in this section
may be performed with the relief valve
still connected to the upstream piping, if
upstream pressure is removed. The pilot
and its pipe nipple must be removed with
the Type 63EGLP/63EGLP-16 Main Valve.
Access to the spring (key 9) or flange
O-ring (key 21) in step 1 can be gained
without removing the body flange (key 2).
