LP GAS SYSTEM
WARNING: LP-Gas is highly volatile and extremely
explosive. Do not use matches or a flame to test for
leaks. Use only approved LP-Gas leak testing solution for leak detection. Unapproved
solutions can damage copper tubing and brass fittings. Never attempt to adjust LP-Gas
regulators. Only qualified personnel should perform any maintenance or repair to the
LP-Gas system.
GENERAL INFORMATION
The liquid petroleum (LP) gas system in your recreational vehicle furnishes the fuel for cooking, heating, and
hot water. LP
gas can also be used as an alternate energy source for refrigeration. LP gas is a clean, efficient,
safe form of energy when proper handling and safety precautions are observed. It enables you to enjoy a
comfortable lifestyle where other forms of energy are not easily utilized.
The gas is stored under extreme pressure in the tank, with space in the tank to allow for expansion into vapor.
This vapor is reduced in pressure by passing through a regulator. This reduction in pressure is a two step
process which assures consistent pressure for use, regardless of outside temperatures, weather, or altitude.
Your LP system is designed to accept either propane or butane. However, since butane vaporizes at about 32
degree F, it can only be used in areas where you can be sure of higher temperatures. Propane vaporizes at
approximately –40 degree F. There are different blends of propane and butane available, which will vary in the
temperature at which it vaporizes. When filling your tank, select an LP gas that has a boiling point of about 40
degrees lower than temperatures you expect to travel in. Talk to your dealer or your local LP gas supplier
about what you should be using.
NOTE: Even though the tank is equipped with an automatic 80% shut-off which prevents overfilling beyond
80% tank capacity, it is a good idea to have the supplier monitor the 20% liquid gauge, and stop the filling
process if liquid does appear.
