Keep air filter screen clean and working properly, es-
pecially in dusty or dry areas.
AUTOMOTIVE AIR CONDITIONER (Optional)
For specific instructions, refer to the information pro-
vided by the air conditioner manufacturer.
CAUTION
THE AUTOMATIC AIR CONDITIONER PLACES AN
ADDITIONAL LOAD ON THE VEHICLE COOLING
SYSTEM. IF ENGINE RUNS ABNORMALLY HOT,
SHUT OFF AIR CONDITIONER UNTIL ENGINE
COOLS DOWN.
LIQUID PETROLEUM GAS SYSTEM
Liquid Petroleum (LP) gas is the energy source for your
range, oven and furnace. It is also an alternate power
source for your LP Gas/E lectric refrigerator.
CAUTION
DO NOT USE NATURAL GAS IN SYSTEM.
LP gas is a colorless gas, but is stored under pressure as a
liquid. The tanks are located in one of the compart-
ments accessible on the outside of the vehicle. It is com-
mercially available under such names as Butane, Pro-
pane, or other brand names. Though odorless in a natur-
al state, LP gas is always odorized to smell like garlic for
easy detection in the event of a leak. The gas and the
liquid tank in which it is stored are safe and convenient,
provided sensible precautions are followed.
CAUTION
LP GAS IS FLAMMABLE AND POTENTIALLY EX-
PLOSIVE. USE PROPER HANDLING, LIGHTING
AND VENTILATING PROCEDURES. AS A GAS, LP
GAS IS HEAVIER THAN AIR AND WILL DISSIPATE
IF VENTILATION IS PROVIDED TO PERMIT A
DOWNWARD FLOW.
USING LP GAS SYSTEM AT LOW TEMPERATURES
Your gas sytem wi II function well at low temperatures,
provided the components are kept at a temperature
above the boiling point of the gas.
NOTE:
Butane boils or turns to a gas at about 32 deg-
rees F and propane boils at about -40 degrees
F.
The following are suggestions to keep gas appliances
working smoothly:
1.
Choose a type of LP gas which has a boiling
point lower than any temperature you expect
to encounter. Ask your LP gas supplier or
your motor home dealer for information on
products available in your area.
2.
If outside temperatures get below the boiling
point of the LP gas in your system, keep ex-
posed area (such as the tank, regulator and
lines) at a higher temperature with a protec-
tive
cover.
3.
Keep the system free from water vapor
(which may turn to ice in lines and regula-
tors). Commercial additives such as dry me-
thyl alcohol, added to the LP gas tank, can
help
avoid
water condensation in the regula-
13
tor and the lines. Ask your LP gas supplier or
your motor home dealer.
If, despite precaution, the gas flow to your appliance
should fail at low temperatures, the stoppage may be
due to ice in the LP gas regulator as a result of condens-
ed moisture. Try melting the ice by warming the regu-
lator, using a small light bulb on an extension cord -
NOT AN OPEN FLAME. Once flow is restored, make
certain that regulator cap is properly installed to prevent
water from entering the regulator which will cause it to
freeze again. If the problem persists, ask your LP gas
supplier to service the tank or regulator, removing the
moisture or adding an ice-inhibitor as required.
OPERATION OF LP GAS SYSTEM
If your motor home has the LP gas stored in removable
tanks, your appliances wi II operate from either tank
through a T-fitting and a regulator (refer to Figure 11).
The first is normally used until empty, then the tank
valve is closed and the second tank opened. Pilot lights
on all appliances need to be relighted after a tank is
switched in this way.
Your system may use LP gas stored in a chassis-mounted
tank (refer to Figure 11). The chassis-mounted tank has
four controls; the gas pressure regulator, vapor with-
drawal service valve, the fill valve and the guage. To pro-
vide LP gas to appliances, first open the vapor with-
drawal service valve all the way (counter-clockwise) then
close it two-thirds of a turn. When all LP gas systems are
not in use, close the valve all the way.
CAUTION
DO NOT USE PLIERS NOR A WRENCH TO TIGH-
TEN VALVES. IF A VALVE IS NOT LEAK-TIGHT
WHEN CLOSED BY HAND, SEE YOUR LP GAS
SERVICE
REPRESENTATIVE. EXTINGUISH ALL
PILOTS AND OPEN FLAMES. STOP THE ENGINE
AND STOP THE AUXILIARY POWER GENERATOR,
IF INSTALLED, BEFORE FILLING LP GAS TANKS
OR
FUELING YOUR VEHICLE TANKS. PILOTS
AND OPEN FLAMES SHOULD BE EXTINGUISHED
WHEN THE VEHICLE IS UNDER WAY AND, BY RE-
GULATION, MUST BE EXTINGUISHED IN CI:.lTAIN
AREAS SUCH
AS
TUNNELS OR
RESTRICTED
AREAS. CHECK AHEAD TO AREAS WHERE YOU
PLAN TO TRAVEL TO DETERMINE ANY SPECIAL
REGULATIONS WHICH MAY APPLY.
FILLING THE REMOVABLE LP GAS TANKS
Removable LP gas tanks should always be removed from
