LIQUID PROPANE GAS SYSTEM

HOW LP GAS WORKS
There are two types of LP (liquid petroleum) Gas:
propane and butane. Both are compressed into a liquid
state for easier transportation and storage. Common
names used for LP Gas are tank gas, bottle gas, or
simply LP.
In the tank, LP Gas is in liquid form and under very high
pressure. As it is released, it changes to a vapor or gas
and expands to a much greater volume.
Exercise caution when temperatures fall below -40 °F
(-40 °C). Propane will not convert from a liquid to a gas
in extremely cold temperatures, and LP Gas appliances
will not function proper
SELECTING FUEL TYPES
Propane burns at a lower temperature and will convert
from liquid to gas at temperatures as low as -40 °F
(-40 °C). Butane is not recommended due to its high
vaporization temperature 32 °F (0 °C). Using butane
in cold temperatures may block the system and cause
components to malfunction.
LP gas dealers typically provide only the type of gas
commonly used and suited for the climate in their area.
If you travel from a warmer to a colder region, verify that
you have the appropriate type of LP Gas for the climate.
LP GAS TANK SYSTEM
The LP Gas storage tank is mounted underneath the
motorhome and is attached to the vehicle floor. It is
accessible only from outside the vehicle. Before turning
on the LP Gas control valve
1
located in the exterior
utility center, make sure all controls for the various LP
Gas appliances are in the “OFF” position to prevent
any LP Gas from leaking into the motorhome. The LP
Gas supply valve is operated by the LP Gas switch in
the exterior utility center. The valve is held open using
12 volt DC power. If the battery is dead or the battery
disconnect is in the “OFF” position, the LP Gas supply
valve will automatically close.

NOTE:
The LP Gas storage tank is also equipped
with a manually operated shut-off valve. Refer to the
“Motorhome Maintenance” section of this manual for
details.
REFILLING THE LP GAS TANK
1. Shut off the LP Gas control valve
1
in the exterior
utility center before filling the tank or traveling.
Always refill an empty LP Gas tank as soon as
possible.
2. Connect the LP Gas supply to the fill connector
2
.
3. Do NOT overfill your LP Gas tank. Stop filling when
liquid appears at the overflow valve
3
(often called
a 10% valve) which limits the liquid level to 80% of
container capacity, allowing 20% for expansion.
4. Check the LP Gas level after refilling by opening the
overflow valve and bleeding gas in a well-ventilated
area until the white liquid stops emerging from
the overflow valve. Overfilling may cause damage
to the regulator and cause malfunction of LP Gas
appliances.
ᘐ
NOTICE
The LP Gas tank has an automatic 80% stop-fill
device to prevent overfilling of the tank. To
prevent against overfilling, have the tank filled
only by an authorized filling station.
The tank is permanently mounted to the motorhome,
therefore, the motorhome must be taken to a fueling
station for refilling. When liquid LP Gas appears at the
overflow valve
3
, the tank is full.
