LIQUID PETROLEUM GAS SYSTEM
Liquefied petroleum (LP) gas is available from an
approved .storage tank to operate your range, oven,
furnace, and water heater, and as an alternate energy
source Jar some refrigerators. With proper handling
precautions, LP gas is safe and provides modern con-
veniences wherever you travel. The LP gas storage
tank is mounted on the motor home chassis. It is
stored as a liquid under pressure and vaporizes under
the control of a pressure regulator.
A typical LP ga's tank installation is illustrated below.
,Although specific details of the system may differ in
your motor home, the major components and their
relationships will be similar to those shown.

LP GAS SAFETY PRECAUTIONS
Historicaliy,LP gas is a safe and reliable fuel. As
with any other volatile and flammable material, com-
mon sense dictates that LP gas be handled and used
with respect and caution. Because LP gas systems
are so reliable, they are often taken for granted.
Neglect can be a very dangerous habit. If the system
is maintained regularly, you can expect almost
troubletree operation.
WARNING: LP GAS IS FLAMMABLE AND
POTENTIALLY EXPLOSIVE. USE PROPER HAN-
DLING,
LIGHTING,
AND
VENTILATION
PROCEDURES.
1.
The distinctive odor of LP gas indicates a leak.
IF YOU SMELL GAS:
•
•
•
Extinguish all open flames, pilot lights and
all smoking materials.
Do not touch electrical switches.
Shut off the gas supply at the tank
valve!s) or gas supply connection.

3.
•
•
•
Open all doors, windows, an,d vents.
Leave the area until the odor clears.
Have the gas system checked and the
cause of the leak corrected before using
the system again.
Inspect the entire LP gas system for leaks or
damaged parts before each trip.
Always be careful when drilling holes or fasten-
ing objectstolhe motor hom~: The gas supp-
.Iy lines could be !lun.ctured.byanail or screw.
4. "Do· not restrict access' to Lp: tanks. In an
emergency, the tank service 'valve must be easi-
ly accessible. The tank compartment door must
always be unlocked.

S.
Do not carry or store· filled .or .empty LP gas
containers inside yourmotor home; LP gas con-
tainers are equipped with a safety device that
relieves excessive pressure by discharging gas
to the atmosphere. Leaks can occur at valves
and fittings. Always store LP tanks with the
valves closed.
Do not use any LP gas tank other than the one
furnished with your motor home without be-
ing sure that all connecting components are
compatible.
. .
WARNING: TURN OFF LP GAS MAIN VALVE
AND INDIVIDUALLY TURN OFF ALL GAS AP-
PLIANCES OR ELECTRICALLY DISCONNECT
AUTOMATIC IGNITION APPLIANCES BEFORE
ENTERING AN LPGAS BULK PLANT OR
MOTOR FUEL SERVICE STATION.
WARNING: DO NOT FILL LP GAS CONTAINERS
TO MORE THAN SO% CAPACITY. OVERFILL-
ING CAN RESULT IN UNCONTROLLED GAS
FLOW WHICH CAN CAUSE FIRE AND EXPLO-
SION. A PROPERLY FILLED CONTAINER
HOLDS ABOUT SO% OF ITS VOLUME AS
LlOUID.
9.
Never.checkior.leaks with an open flame. Use
ail approved leak detection solution or a non-
ammoniated, non-chlorinated soap solution on-
ly. If the leak cannot be located, take the unit
to an LP gas service: representative.
10.
LP gas regulators must always be installed 'with
the diaphragm vent facing downward. Make
sure that the regulator vent faces downward
and that the cover is kept in place to minimize
vent blockage which could result in excessive
gas pressure causing fire or explosion.
11.
Do not use a wrench or pliers to close the ser-
vice valve. This valve is designed to be closed
leak-tight by hand. If a tool is required to stop
a leak, the valve probably needs repair or
replacement.
12.
Use proper tools to tighten fittings. Don't force,
jam or crossthread fittings. Always check fit-
tings for leaks after tightening.
