Section 7: Fuel & Propane System
The propane fuel system is comprised of numerous components such as the propane con-
tainer, hoses, propane gas regulator, piping and copper tubing to each appliance.
Your motorhome has been carefully tested at the factory and by your selling dealer for
leakage. Travel vibrations can loosen fittings. Have the vehicle propane system checked
at all connections soon after the purchase of your vehicle, and after the initial filling of the
propane tanks.
Continued periodic checks of the propane system at 5,000 miles of travel (or at least once a
year) by a qualified propane service representative as part of your normal maintenance is
recommended. Hand tighten the LP gas system valves only, do not use a wrench or pliers as
over tightening may damage the valve seals and cause them to leak.
The following label should be kept permanently affixed to the motorhome:
Propane Gas Container
Propane is a true gas compressed into a liquid form. As the fuel is released from the con-
tainer, it changes to vapor which is then used for the operation of the appliances. Propane
will not run through the appliances in the liquid state.
A permanently mounted A.S.M.E. approved propane container is located under the floor of
the motorhome.
NOTE: All propane lines have been checked with air pressure at the time
of manufacture. Dealers are required to recheck and adjust pressure before
retail delivery.
Propane cylinders should not be placed or stored inside the vehicle. LP-gas
cylinders are equipped with safety devices that relieve pressure by discharging
gas into the atmosphere.
