How LP Gas Works

There are two types of LP (Liquified Petroleum) gas - propane and butane. Both are compressed into a liquid for easier
transportation and storage. Common names used are tank gas, bottle gas, or simply LP.
In the tank, LP gas is in the form of a liquid under very high pressure. As it is released, it changes to a vapor or gas
and expands to a much greater volume.
Caution should be exercised when temperatures fall below -40 °C (-40 degrees °F). You could be without propane at
these lower temperatures.

LP Gas Tank System

The LP gas storage tank is mounted underneath the Motorhome attached to the vehicle floor. It is accessible only
from outside the vehicle. The tank valve is located near the top center of the tank next to the regulator. Before opening
the supply valve, make sure all controls for the various appliances are in the "OFF" position. This is to prevent any LP
gas from leaking into the Motorhome. The supply valve is operated by the LP gas switch on the monitor panel. The
valve is held open using 12 volt DC power. If the battery is dead or the battery disconnect is switched off the valve will
automatically close. NOTE: The LP gas storage tank is also equipped with a manually operated shut-off valve.
See the maintenance section of this manual for details.
Refilling the LP Gas Tank
To fill the LP gas tank:
1. Shut off the LP gas control valve on the utility center
panel via the rocker switch (1) when filling the tank
and during travel. Always refill an empty LP gas tank
as soon as possible.
2. Connect the LP gas supply to 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 contacts the liquid level at 80% of
container capacity allowing 20% for expansion.
4. Check after each filling by opening the overflow valve
and bleed gas in well-ventilated area until white liquid
stops. Overfilling may cause damage to the regulator
and cause malfunction of LP gas appliances.
IMPORTANT
The LP gas tank has an automatic 80% stop-fill
device to prevent over filling of the tank. To ensure
against over filling, it may be advisable to 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 to be filled. When the liquid LP gas appears at
the overflow valve (3) the tank is full.
LP gas stations are found in all parts of the country.
Check the yellow pages in your telephone book if you
have trouble finding a station. Look under "Gas - Liquified
Petroleum - Bottled and Bulk" or "Propane."
