SECTION 8
– LP Gas System
Class A
8 – LP Gas System
AIR IN THE LP GAS TANK
If your LP gas appliances do not stay lit or
require frequent adjustment, even though you
know the LP tank contains sufficient fuel, the
problem may be air in the LP gas tank. Air in the
tank mixes with the LP gas vapors causing them
to burn poorly. This condition could linger for
weeks if the air is not purged from the tank. Most
LP gas dealers have equipment for purging air
from LP gas tanks and will purge before refilling
the tank.
TRAVEL WITH LP GAS
It is illegal for vehicles equipped with LP
tanks to travel on certain roadways or through
certain tunnels in the U.S. To avoid
inconvenience, check state regulations
concerning flammable gas transportation.
PRESSURE REGULATOR
The pressure regulator is protected from the
elements by a plastic cover which should be left
in place at all times. Only your dealer or a
qualified LP gas service should remove the
regulator cover for adjustments.
WARNING
DO NOT FILL CONTAINER TO MORE
THAN 80 PERCENT OF CAPACITY.
Make sure the motor home is level when
filling. It is possible to accidentally overfill
the tank if the vehicle is unlevel, with the
fill valve on the uphill side. Overfilling the
LP gas tank can result in uncontrolled gas
flow, which can cause fire or explosion. A
properly filled container will contain
approximately 80 percent of its volume as
liquid LP gas.
All pilot lights must be extinguished
and supply valve closed before refilling
LP gas tanks or vehicle fuel tanks.
Do not smoke or expose an open flame
while near an LP refueling area. LP gas is
heavier-than-air and extremely
flammable.
Never use an open flame
to test for LP
gas leaks.
Replace all protective covers and caps on
LP system before filling.
Never
fill the LP tank with engine or
generator running.
WARNING
Visually inspect the pressure regulator
vent periodically for blockage by
accumulated debris or insect nests, etc.
Vent obstruction could result in excessive
pressure which could cause a fire or
explosion.
If any obstruction is apparent, have the
regulator serviced by your dealer or a
qualified LP gas service center.
