LP-Gas exists in both the liquid and vapor state within the LP-Gas tank. A
“ FULL ” tank is approximately 80% liquid. The pressure inside the tank varies
with the temperature of the liquid. All tanks are required to be equipped with a
pressure relief device. The purpose of the relief valve is to release gas or liquid
caused by being over pressurized. The gauge at the tank, when full, will only
read 3/4 full. The monitor panel is adjusted to indicate “
FULL” at this point.
When storing portable LP-Gas tanks that are not connected to an LP-Gas
system, install an approved plug in the tank outlet holes to prevent leaks. Do
not transport or store LP-Gas tanks, gasoline or other flammable liquids inside
the motorhome.
WARNING: Do not store or transport empty LP-Gas tanks,
portable tanks, gasoline or other flammable liquids inside
the motorhome. Keep open flame and spark producing mate-
rials away from the LP-Gas area. Shut off all appliances and
LP-Gas tank valve (located on side of LP-Gas tank under-
neath the motorhome) when the motorhome is in storage. If
this warning is ignored a fire or explosion could result.
CAUTION: Pressure inside LP-Gas tanks can reach over
200 psi when exposed to direct sunlight. A high pressure
safety relief valve will purge excess high pressure if necessary.
LP-Gas will stop vaporizing as the LP-Gas tank tempera-
ture approaches -40º F. Appliances that consume large
amounts of LP-Gas, such as the water heater or furnace,
will need to be operated in sequence in extremely cold envi-
ronments.
Tank Operation:
• Manually open the primary shut-off valve located on the LP-Gas tank.
• Turn off the primary valve on the LP-Gas tank when the motorhome is in
between trips.
• Hand tighten the primary valve. Do not use a wrench or pliers to close the valve.
• The primary valve is designed to be closed by hand, over tightening may perma-
nently damage the valve seat.
