PROPANE FUEL SYSTEM________________________________
The fuel system in your recreational vehicle has numerous compo-
nents such as, piping, copper tubing, brass connectors, hoses,
regulators and appliances. Each of these components will be ex-
plained in its appropriate area.
Propane is the only fuel permitted to be used in a recreational vehi-
cle 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 pro-
pane vapor.
Butane cannot be used since its boiling point is 30°F. This fuel will
not flow in freezing temperatures.
Natural gas and methane CANNOT be used in any KZRV recrea-
tional vehicle or it’s appliances.
Propane fuel is stored in liquid form under high pressure in special
containers. Boiling point is 44°F, 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. Liq-
uid will damage o-rings in valves and also leave sticky, oily residue
causing poor or no operation in the regulator.
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
acme cylinder valve, is to be closed at all
times unless hooked up to a propane system
or when filling the container.
At any point a container is disconnected, BE SURE to install the
“dust cap” over the acme valve. This cover is required by the RV
Industry Gas Association, the container manufacturer, and is for
your safety.
