To Install an Additional Pilot
This section only applies to
Type 63EGLP/63EGLP-16 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)
1. The Type 6358EBLP Pilot ships preassembled with
a 1/4 in.-by-Compression elbow (key 43, Figure 15)
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.

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.
Note
CAUTION
Type 63EGLP/63EGLP-16
△
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.
7. Apply thread sealant to exposed end of the
6 in. Male NPT pipe nipple. To install the new pilot,
thread pilot Port D onto the pipe nipple until snug,
tightening until the spring case and compression
fitting are oriented in the same direction as the main
valve outlet.
8. Orient the stainless steel tubing (key 44) to
connect the compression fitting on the pilot to
the compression fitting on the 3-way valve. Finger
tighten the compression fitting assembly, then use
appropriate 11/16 wrench to turn the nut 1/4 turns
(assuming the ferrule is already clamped to the tube).
△
CAUTION
A small amount of vapor release
may occur during steps 10 and 11. If the
main valve or alternate pilot continuously
vents while conducting steps 10 or 11,
return the handle to the previous position
and contact your local LP-Gas distributor.
9. Locate the wire seals securing the sliding lock
mechanisms on the 3-way valve handle and
remove them. The wire seals are factory installed to
discourage tampering from untrained professionals
and should be replaced upon completion.
