7. Clean the exposed pipe nipple and apply new
thread sealant before threading the new pilot onto
the nipple. Make sure the pipe wrench is utilized
to secure the pipe nipple. Install the pilot such
that the pipe nipple threads into Port D. Continue
tightening until snug, tightening further until the
pilot adjusting screw points in the same direction
as the outlet of the main valve body.
8. Re-attach the 11/16 in. compression fitting
assembly on the stainless tube connecting the
pilot and 3-way ball valve. Finger tighten the
compression fitting assembly, then use appropriate
wrench to turn the nut 1/4 turns (assuming the
ferrule is already clamped to the tube).
9. Slowly reverse step 3, taking note of the preceding
cautions. 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.
10. 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.
Refer to step 4 to properly purge the reserve pilot.
After purging the reserve pilot, finger tighten the
compression fitting, then use appropriate wrench
to turn the nuts to 1/4 turn. Install the wire seals.
To Install an Additional Pilot
This section only applies to
Type 63EGLP assemblies received with
one pilot. if your assembly has two
pilots, skip to section To Change Out
a Pilot. installing the additional pilot
requires the following tools and Fisher™
Key numbers:
• Wrench Sizes (recommend open-
ended or adjustable): 9/16 in.,
11/16 in. and 7/8 in.
• Pipe Wrench: recommend maximum
length: 12 in.
• Required Fisher Key numbers
(QTy): 36 (x1), 43 (x1), 44 (x1),
Matching Type 6358EBLP Pilot (x1)
• Fisher Key numbers (QTy): 49 (x2)
note
1. The Type 6358EBLP pilot ships preassembled
with a 1/4 in.-by-Compression elbow (key 43,
Figure 9) in Port C oriented in the same direction
as the spring case. If your pilot does not have this
elbow installed, please contact your local Fisher
LP-Gas Distributor to obtain the correct part.
2. Confirm that the handle assembly is pointing
AWAY from the ACTIVE pilot. The handle
assembly has a sliding lock mechanism that is
wire sealed at the factory before shipment. If
the wire seal has been damaged or is missing,
proceed with caution.
CauTiOn
Product may be trapped between the
3-way valve seal and the pipe plugs. use
caution when proceeding to step 3.
3. Secure the first 3-way valve with an appropriate
7/8 in. wrench. Using an appropriate 9/16 in.
wrench, slowly remove the 1/4 NPT pipe plug.
If any pressure is trapped between the 3-way
valve and the plug, it should quickly dissipate. If
pressure continues to bleed, reinstall the plug and
contact your authorized Fisher LP-Gas Distributor
as the 3-way valve may need replacing.
4. Repeat step 3 on the remaining 3-way valve.
CauTiOn
Only apply thread sealant to Male nPT
threads. Sealant applied to female pipe
connections or to compression fittings
could inhibit the seal and result in a leak
or product contamination.
5. Clean the FNPT threads on the 3-way valves.
Apply thread sealant to one end of the
6 in. Male NPT pipe nipple (key 36) and install
the pipe nipple into the lower 3-way valve
Female NPT connection. Tighten it in place with an
appropriately size pipe wrench.
6. Apply thread sealant to the Male NPT end of one
of the 1/4 in.-by-Compression elbows (key 43).
Using an appropriate 5/8 in. wrench, install the
compression fitting in the Female NPT outlet of the
upper 3-way valve until snug, tightening until the
compression fitting is facing in the same direction
as the main valve outlet.
