Propane Fuel System
The fuel system in your recreational vehicle has numerous components
such as: piping, copper tubing, brass connectors, hoses, regulators, and
appliances. Each of these components will be explained in its appropriate
area.
Propane is the only fuel permitted to be used in a recreational vehicle and
its appliances. This product is refined from crude oil through natural
gasses. An agent has been added for detection should a leak occur or a
valve accidentally be left open. It is important for a recreational vehicle
owner to recognize and identify the smell of propane vapor for his or her
safety.
Other fuels are available but CANNOT be used in a RV because;
1. No orifices are available for appliances for either butane or
natural gas fuels.
2. Butane CANNOT be used below freezing temperature because
boiling point is 30 degrees.
Propane fuel is stored in liquid form under high pressure in special
containers. Boiling point is (minus) -44 degrees, the temperature when
vapor ceases to flow. Fuel will change to vapor when released from the
container. Appliances are not designed to operate with liquid. Liquid will
damage O-rings in valves and also leave sticky, oily residue causing poor
or no operation in the regulator.
For every 10 degree increase in temperature, the pressure of propane in
a container rises 1.5%. Example, if you fill your container in the north and
its 0 degrees outside, then you go south and its 80 degrees outside, you
now have a container filled at 92%, a potential problem with 10% valve
spewing out propane vapor.
Propane Container
The propane cylinder is a D.O.T. approved
container to hold liquid under high pressure,
normally a 20 or 30 pound capacity.
The open/closing valve, referred to as an OPD
cylinder valve, is to be closed at all times, unless
hooked up to a propane system or when filling the
container.
Valve assembly actually has three valves in one
body.
1. Main pass thru portion to fill container and draw propane from,
is controlled by upper three sided knob.
2. 10% valve, a small screw on the side of main body allows any
