A permanently mounted A.S.M.E. (American Society of
Mechanical Engineers) approved propane container (tank)
is mounted under the floor of your motorhome. A fill port
with a main LP gas shut-off switch is located on the LP access
panel, positioned along the lower left side of the vehicle.
Propane expands 1½ percent for every ten degrees Fahrenheit
of increase in temperature. When filling, it is imperative to
leave sufficient space inside the container to allow for natural
expansion of gas during warmer weather.
Monitoring Propane Levels
The amount of propane contained in the propane tank can
be monitored by pressing the appropriate monitor buttons
on the motorhome's main multiplex system panel. Refer to
Electrical System Section.
Filling and Servicing the Propane Tank
Given that the propane tank is not removable, the motorhome
will need to be driven to a qualified propane facility for filling
and servicing. Only an authorized propane service techni-
cian(s) should be near the motorhome while the propane
tank is being filled. Drivers and passengers should wait at a
safe distance away from the motorhome until LP filling and
servicing is complete.
NEVER OVERFILL THE PROPANE TANK!
Never allow your propane tank to be filled above the maxi-
mum safe level as indicated by the fixed liquid level gauge (if
equipped). Overfilling the propane container above the liquid
capacity indicated on the gauge could allow liquid propane
to enter the system that is designed for vapor only, creating a
hazardous condition.
NOTES:
• The capacity or size of a propane tank is expressed in
pounds (lbs.) and correlates to the weight of the pro-
pane it is capable of containing when filled to 80%
capacity, not the total volume capacity of the tank.
• For example: If your motorhome has a 40 pound
capacity LP Tank, filling it to 80% = 32 pounds of
LP. LP weighs 4.2 lbs/gallon, so the 80% capacity
of a 40 pound LP tank is 7.6 gallons (32÷4.2).
New propane containers are filled with an inert
gas, which must be carefully purged before filling
with propane. The propane tank must NEVER BE
OVERFILLED with propane (more than 80% by volume).
If you suspect your propane container has been
overfilled, immediately contact your selling dealer
or a qualified propane technician for assistance. Do
not attempt to service or correct a propane container
overfill yourself.
WARNING WARNING
Hand tighten propane gas system valves only; do not
use a wrench or pliers as over tightening may damage
the valve seals and cause them to leak.
NOTICE NOTICE
Never use another LP tank other that the one furnished
with the motorhome. If the LP tank must be replaced,
check with your dealer for correct LP tank specifications
and replacement procedures.
CAUTION CAUTION
Do not fill propane container(s) to more than 80
percent of capacity. A properly filled container contains
approximately 80 percent of its volume as liquid
propane.
Overfilling the propane container(s) can result in
uncontrolled propane flow, which could lead to a fire or
explosion and result in death or serious injury.
If you suspect your propane container has been
overfilled, immediately contact your selling dealer
or a qualified propane technician for assistance. Do
not attempt to service or correct a propane container
overfill yourself.
WARNING WARNING
Propane tanks are to be installed, fueled, and
maintained in accordance to country, federal, state,
and local codes, rules, regulations, laws, or guidelines.
