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.
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 ex-
ample 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 avail-
able 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.

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.
