LP-Gas VaLVes
Operating & Monitoring
Open both LP-Gas primary shut-off valves. The tank to which the “lever” on the changeover valves point
is the service tank. As long as there is fuel in the service tank the full-empty indicator on top of the valve will
show green. When the service tank is empty the automatic regulator will switch over using fuel from the second
tank. When this happens the full-empty indicator will change from green to red. At this point the valve on the
empty tank should be shut off. Manually move the lever on the changeover valve to face the other tank. This tank
then becomes the service tank and the full-empty indicator will again show green. The empty tank may now be
disconnected for refilling. After the tank has been refilled and installed it becomes the second tank.
LP-Gas Primary Shut-off Valve Tips:
• Turn off manual primary shut-off valves on the LP-Gas tanks
when the recreational vehicle is between trips.
• Hand tighten the manual primary shut-off valves. Do not use a
wrench or pliers to close the valves. The manual primary shut-
off valve is designed to be closed by hand, over-tightening may
permanently damage the valve seat.
LP-Gas FunDamentaLs
• LP-Gas detectors are a Federal requirement on all LP-Gas equipped recreational vehicles.
• LP-Gas is a by-product produced by refining oil.
• Odor is added to LP-Gas after the refining process.
• Each liquid gallon of LP-Gas produces 91,502 BTU (British
Thermal Units).
• Temperature effects pressure of LP-Gas. Internal tank pressure
can exceed 200 psi.
