LP Gas System
~.
WARNING
7. Turn off LP gas main valve before filling LP gas
container or entering an LP gas bulk plant or motor
fuel service station. Turn off all pilot lights and appli-
ances individually before refueling of motor fuel tanks
and/or LP gas containers. When not individually
turned off, automatic ignition appliances may continue
to spark when LP gas is turned off at the container.
S. Do not fill LP gas containers to more than SO%
capacity. Overfilling can result in uncontrolled gas flow
which can cause fire and explosion. A properly filled
container holds about SO% of its volume as liquid.
9. 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 LP gas pressure causing fire or
explosion.
10. Do not use a wrench or pliers to close the tank
shut-off valve. This valve is designed to be closed by
hand. If a tool is required, the valve probably needs
repair or replacement.
SYSTEM COMPONENTS
Hoses
The hoses used in your LP gas system meet
stringent requirements, and are rated to with-
stand many times the pressures encountered in
the system. Check the hoses for weather check-
ing or other signs of deterioration every time
you have the LP gas tank filled or serviced.
When you replace hoses, be sure that replace-
ments are properly rated and approved for RV
use.
LP Gas Regulator
The two-stage regulator produces II inches of
water column to serve your appliances. Be sure
the regulator vent stays clean and free from
obstructions.
The regulator is mounted so that the vent is fac-
ing downward and is protected by a cover. Be
sure the cover is on at all times. If the vent
becomes clogged, it can be cleaned with a tooth-
brush. If corrosion is evident, contact a qualified
LP gas service technician for assistance.

WARNING
Do not attempt to adjust the regulator. It has been pre-
set by the regulator manufacturer. If any adjustment is
required, it must be made by a qualified LP gas serv-
ice technician using special equipment.
USING LP GAS SYStEM AT
LOW TEMPERATURES
Your LP gas system will function at low temper-
atures, provided the system components are kept
at a temperature above the vapor point of the LP
gas. Ask your LP gas supplier or your motor
home dealer for information on product blends
available in your area and the areas in which
you will be traveling.
The following chart shows the reduction in
available BTU's/hour under various fill levels as

The chart clearly shows how the availability of
the gas is reduced at lower temperatures. With
this in mind, keep your LP gas tank as full as
possible during cold weather. Check the BTU/hr
rating plates on your LP gas appliances. This
information will help you manage your LP gas
usage.
FILLING LP GAS TANKS
To fill the chassis-mounted storage tank, drive
the vehicle to an LP gas supplier or a service
station which sells LP gas. Do not attempt to fill
the LP gas tank yourself.
