DEWINTERIZING & SPRINGTIME TUNE UP (3 of 3)

LP SYSTEM

Propane gas is highly volatile and awfully explosive. Do not use matches or a flame to test for leaks. Use only approved propane gas leak testing solutions for leak detection.

  • The propane gas system furnishes the fuel for cooking, heating, and hot water.
  • Propane gas can also be used as an alternate energy source for refrigeration.
  • Propane is a clean, efficient, safe form of energy when proper handling and safety precautions are observed.
  • The Propane Gas system is designed to accept either Propane or Butane. However, since Butane vaporizes at about 32°F, it can only be used in areas where you can be sure of higher temperatures. Propane vaporizes at approximately -40°F. There are blends of Propane and Butane available, which will vary in the temperature at which it vaporizes. When filling the tank, select a Propane Gas that has a boiling point about 40° lower than temperatures you expect to travel in. Consult with your dealer, or local Propane Gas supplier about what you should be using.
  • 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.
  • MAKE SURE THAT THE TANK IS NOT FILLED BEYOND THE 80% LIQUID LEVEL. Even though the tank is equipped with an automatic 80% shut-off which prevents over-filling 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. If the tank has been over-filled, make sure the propane supplier bleeds out the excess. Over-filling the propane gas container does not allow for the necessary 20% vapor expansion space and may result in an uncontrolled gas flow which can cause a fire or explosion.
  • Before entering the propane bulk plant or service station, make sure all pilot lights are extinguished. Shut off gas to all appliances by first turning off each appliance, and then close the propane gas main shut-off valve.
  • Extinguish open flames and smoking materials.
  • Never remove the propane gas tank from the motorhome. Always drive the motorhome to the gas supplier to fill.
  • Have the supplier connect the fill nozzle to the tank fill connection.
  • Always remember to close the supply valve and open the 20% liquid level valve.
  • Never use a wrench to close the service or the 20% liquid level valve. If when closing by hand, leaking occurs, have the valve repaired or replaced.
  • Drive at least one mile from the propane gas supplier before relighting pilot this will allow any minimal leakage to dissipate.

If you smell propane gas:

  • Extinguish any open flames, pilot lights and all smoking materials.
  • DO NOT touch any electrical switches.
  • Shut off the gas supply at the tank valve(s) or gas supply connection.
  • Open all doors and other ventilating openings. DO NOT USE THE RANGE HOOD.
  • Leave the area until the odor clears.
  • Have the system checked by a trained professional before using again.

When performing any work or maintenance in the motorhome, ensure that you do not puncture a gas line with a nail, screw, or drill bit.

Warning labels and decals are used throughout the motorhome in locations where the potential for a dangerous situation is present. They have been installed not only because of the requirement to do so, but also as a constant reminder to occupants of the motorhome to exercise proper caution when using or being around propane gas appliances and equipment. Make sure that you and your family understand and follow all of them. Never remove these warning labels and decals. If one should be lost, it should be replaced as soon as possible.
