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 or it’s ap-
pliances.
Propane fuel is stored in liquid form under high pressure in special
containers. Boiling point is (minus) — 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.
Liquid will damage o-rings in valves and also leave sticky, oily resi-
due causing poor or no operation in the regulator.
For every 10 degree increase in temperature, the pressure of pro-
pane in container rises 1.5%. Example—fill at 0 degrees in north, go
south to 80 degrees, you now have container filled at 92% ,a poten-
tial problem with 10% valve spewing out propane vapor.
Propane Container
The propane cylinder is D.O.T. approved con-
tainer to hold liquid under high pressure, nor-
mally 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
Acme Cylinder
