LP GAS SYSTEM
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 rela-
tionship to a decrease in temperature. Propane
will convert to a usable gas at temperatures down
to -44
°
F. For this reason, propane is a popular
heating fuel in cold climates. However, even pro-
pane vaporizes at a slower rate as it becomes
colder.
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
an 84-pound 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 Tem-
perature Relationship chart typifies the LP gas
loss with a decrease in temperature. The percent-
age figures are the increase or decrease of vapor
that would be available at 0
°
F. These figures ap-
ply to any size LP gas tanks.

not vaporize
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.
