DANGER
IF YOU SMELL GAS
1.
EXTINGUISH ANY OPEN FLAME, PILOT LIGHTS AND
ALL SMOKING MATERIALS.
2.
DO NOT TOUCH ELECTRICAL SWITCHES.
3.
SHUT OFF THE GAS SUPPLY AT THE TANK VALVE(S)
OR GAS SUPPLY CONNECTIONS.
4.
OPEN DOORS AND OTHER VENTILATING OPENINGS.
5.
LEAVE THE AREA UNTIL ODOR CLEARS.
6.
HAVE THE GAS SYSTEM CHECKED AND LEAKAGE
SOURCE CORRECTED BEFORE USING AGAIN.
FAILURE TO COMPLY COULD RESULT IN
EXPLOSION RESULTING IN DEATH OR
SERIOUS INJURY.
WARNING
Never use an open flame to test for
gas leaks.
LP GAS ALARM - See page 1-2.
WARNING
Never use an open flame to test for
gas leaks. When testing for gas lines
leaks with a soapy water solution, DO
NOT use a detergent containing
ammonia or chlorine. These sub-
stances may generate a chemical
reaction causing corrosion to gas
lines, resulting in dangerous leak con-
ditions.
WINTER USE OF LP GAS
Due to vaporization characteristics of LP gas,
it is important that the winter camper knows how
to most efficiently use the LP system. The vapor-
ization rate of LP gas decreases in a direct
relationship to a decrease in temperature. Pro-
pane will convert to a usable gas at temperatures
down to -44°F. For this reason, propane is a pop-
ular heating fuel in cold climates.
LP GAS SYSTEM
The greater the amount of liquid gas in the
tank (up to 80% level) the greater the amount of
LP gas vapor generated. The following is an
example of the number of BTU's available from
a 20-gallon tank at 0° F at three levels. As you
can see, the number of BTU's decreases as the
tank is emptied. Nearly twice as many BTU's are
available from a full tank than one that is one-
fourth full.

The following LP Gas Vaporization and
Temperature Relationship chart typifies the LP
gas loss with a decrease in temperature. The
percentage figures are the increase or decrease of
vapor that would be available at 0°F. These
figures apply to any size LP gas tanks.
