Valve Assembly Precautions (Fig. 1)
1. Use new, properly reamed, pipe, free from chips.
2. Do not thread pipe too far into pipe adapter. Valve
distortion or malfunction can result from excess pipe in
the valve.
3. Do not attach valve actuator until valve body installation
is complete.
4. Make sure O-ring sealing surfaces are clean.
5. Apply moderate amount of good quality pipe dope,
resistant to the action of liquid propane (LP) gas only
on the pipe threads.
6. Make sure the gas flow is in the direction of the arrow
on the gas valve casting.
NOTE: Gas flow in the V4297S Normally Open Vent Valve
can be in either direction.
