NOTE: The information is not a
complete guide for the use of LP-
Gas tanks or appliances. In cold
climates keep fuel levels above
50% in order to keep vaporization
of LP-Gas at the highest level.

Basic Facts About LP-Gas:
• LP-Gas detectors are a federal requirement
on all LP-Gas equipped recreation 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.
• Tanks or valves contain pressure relief
valves. The relief valve opens at 125% above
tank rating.
• LP-Gas stops vaporizing at -44º F.
• Standard LP-Gas operating pressure is 11"
of Water Column or approximately 6 ¼
ounces per square inch.
• An inch of Water Column is a measurement
of applied pressure to one side of a U-Tube
½ filled with water at sea level. The amount
of pressure required to raise the water level
11", represents 11” of Water Column.
