Emer PRD Replacement for Gillig CNG
Fuel Systems with Type 4 Cylinders and Electric Solenoid Cylinder Valves
ENP-740 REV A
August 5, 2020
1. Introduction
Agility Fuel Solutions (Agility®) has determined that pressure relief devices (PRDs) manufactured by Emer™ may fail to operate as designed. This issue has been reported to the National Highway Traffic and Safety Administration (NHSTSA Recall No. 20E-019). Impacted parts include Emer™ p/n PRD2302T-004 (Agility® p/n 10306997) and Emer™ cylinder valve PRD, p/n PRD2102T (no equivalent Agility® p/n) used in Agility® compressed natural gas (CNG) fuel systems produced from October 6, 2016, to April 1, 2020.
PRDs are essential for safe vehicle operation and must be replaced if non-compliant. Agility® personnel have identified fuel system top level part numbers supplied for Gillig buses containing recalled Emer™ PRDs as original equipment manufacturer (OEM) equipment.
Agility® has engineered two retrofit kits for fuel systems equipped with Type 4 cylinders and manual cylinder valves to replace recalled Emer™ PRDs. The two retrofit kits replace 85-in. and 120-in. fuel system plumbing with PRDs manufactured by VTI and new PRD supply and vent tubes. Agility is also supplying Emer™ cylinder valve PRD, p/n PRD2102T (no equivalent Agility® p/n) for cylinder valve direct replacement.
Agility® created this instructional document to guide trained CNG fuel system service technicians in the removal, replacement, and reporting of affected Emer™ PRDs.

INSTRUCTION MANUAL TO REPLACE THE PRD
GENERAL INSTRUCTIONS
Read carefully the instructions before proceeding with the replacement of the Pressure
Relief Device (PRD) Temperature Activated. The maintenance described hereinafter shall
be done only by the authorized workshops/operators after Emer S.p.A. approval.
Don’t damage or tamper in any way the valve and its equipment.
Don’t use components having damaged packaging, fallen or showing sign of collision
and/or damages.
Don’t make operations different from those explicitly described in this instruction
manual.
All the equipment used for the hereinafter listed operations, shall be suitable to the
using and calibrated (where applicable).
For what not expressly described, the indication reported within the standard ISO 19078
“Gas cylinders — Inspection of the cylinder installation, and requalification of high
pressure cylinders for the on-board storage of natural gas as a fuel for automotive
vehicles” and the following have to be used.
Before conducting following activities it is mandatory that inside the
CNG tank and the downstream systems there isn’t any residual pressure. This
means that the tank, the piping, etc. should be completely vented.
Pay attention not to damage the components during the following activities.

1. Unpack the fresh PRD keeping the plastic bag, the protective plastic cap and the
main carton box.
2. Unscrew the PRD Part 2 at Fig 1.
3. Remove the previous O-ring from the seat at the valve body, blow compressed air
into the seat of the PRD and check that the fresh PRD is having the O-ring at the
proper seat.
4. Apply the sealant as specified at Table 1 on the threads of the new PRD and screw
the PRD into the threaded seat at the valve body.
5. Tighten the PRD with a dynamometric key size 24 set at a torqueing value as declared
in Table 1.
6. Pressurize the system at min 200 bar with CNG. The pressurizing of the CNG can be
done either with a back-up CNG tank or at the CNG filling station. Do not use CNG
fast filling stations for pressurizing the systems. In case of multiple tanks all the
tanks must be pressurized (all the PRDs present in the system should be replaced
before conducting the leak test at Step No 7).
7. Check the tightness of the PRD at the sealing area of the valve using either sniffer
measuring machine (preferably) or with snoop solution (in case sniffer machine is
not available). With snoop solution the PRD is leak proof in case of no bubbles. If
sniffer machine is used please contact Emer at emer-service@wfsinc.com specifying
the technical details of machine for defyning acceptance criteria.

- 【TWO MODES】: The 1/2 PSI gas regulator have both propane and natural gas mode. The factory setting of the nature pressure regulator is propane mode, if you need natural gas mode, please open the knob on the cover to convert the screw to natural gas mode, please refer to our picture for details.
- 【SPECIFICATIONS】:The therad on the Regulator is 1/2" Male Thread and the end of house is 3/8" Female Flare. When using LPG regulating valve: LP inlet pressure is 2.74Kpa(11 "w.c), outlet pressure is 2.45~2.55 kpa(10 "w.c), gas flow rate is 30L/min; When using natural gas regulating valve: LP inlet pressure is 1.74Kpa(7 "w.c). Outlet pressure is 0.95~1.05 kpa(4 "w.c), flow rate is 50L/min.
- 【FUNCTIONS】: This 102-B model rugulator converts your equipment that uses propane to one that uses natural gas. You can use it to replace the Kitchen Aid Natural Gas Conversion Kit 710-0003.Functions the same as the original part contents.
- 【CONVERSION MODEL】: This natural gas pressure regulator can converts these KitchenAid grill models to NG: 720-0709, 720-0709B, 720-0709C, 720-0733, 720-0733A, 720-0745, 720-0745A, 720-0745B, 720-0787, 720-0787D, 720-0819, 720-0819A, 720-0891B, 720-0826, 720-0891R, 720-0893.
- 【WARM TIPS】: The natural gas conversion Kit is rated to operate from -32°F to 225°F (0°C to 107°C) Do not install the regulator too close to heating equipment or use it in very cold environments. Heat and cold will change the resistance of the spring inside the regulator. The gas pressure regulator will not shut off the gas flow.
