V5197A FIRING RATE GAS VALVE
Installing the V5197 in the IVT
Refer to the Integrated Valve Train Installation instructions
(form 66-1099) for complete instructions on mounting a
V5197A in a Honeywell Integrated Valve Train System.
Allow sufficient clearance for assembling the motor and
linkage (if applicable), and for general servicing.
IMPORTANT
Install the valve so the arrow on the valve body
points in the gas flow direction. Make sure the O-ring
seals (provided) are properly positioned and seated
at the inlet and outlet flange connections.
1. Install the V5197 Valve so the arrow on the valve body
points in the gas flow direction.
NOTE: Normally, the V5197 will be located
downstream of the safety shutoff valve(s) in
the Integrated Valve Train.Refer to form
66-1099 or the following steps.
2. Using the grease packet provided (or equivalent,
general purpose, lithium grease), grease the O-rings
provided with the valve. Make sure the grease is applied
evenly around the O-ring. See Fig. 13.
Mounting the ML7999 Mounting Bracket
The ML7999 Actuator and mounting bracket can be installed
in one of four positions, depending on accessibility of the
valve and actuator. See Fig. 15.

3. Connect the V5197 Valve to the safety shutoff valve
(SSOV) using three bolts, nuts and lockwashers as
shown in Fig. 13.
NOTE: Tightening torque for nuts/bolts:
• Small body flanges: 13 ft-lb (18 N-m).
• Large body flanges: 25 ft-lb (34 N-m).
4. Connect the pipe adapter to the other end of the V5197
Valve using three bolts, nuts and lockwashers.
5. Assemble the downstream gas piping:
a. Use new, properly reamed, pipe, free from chips.
b. Apply moderate amounts of good quality pipe dope,
resistant to the action of liquid propane (LP) gas,
on the pipe threads. See Fig. 14.
c. Do not thread pipe too far into pipe adapter.
The pipe should end flush with the O-ring sealing
surface of the pipe adapters. Valve distortion or
malfunctions can result from excess pipe in the
valves.
6. Mount the ML7999 Actuator on the V5197 Valve and
secure the actuator to the mounting bracket.
7. Wire the ML7999 Actuator according to instructions
in form no. 65-0239.
8. Restore power to the system.
