LP GAS SYSTEM

SELECTING LP
FUEL TYPES
We recommend using straight propane in your
LP tank. LP gas is available in two types - pro-
pane or butane, and may be available as a butane-
propane mixture.
NOTE: Many RV appliance manufacturers rec-
ommend avoiding butane or butane/pro-
pane blends. Butane burns about 30
percent hotter than propane and can
overheat some appliances, particularly
refrigerators, and cause permanent
damage. Other appliances designed to
operate on propane can become sooted
and lose efficiency by using butane fuel.
Propane is commonly available in most loca-
tions. LP gas used as a motor vehicle fuel (for
tractors, generators, forklifts, etc.) must be pure
propane, so even in areas where butane mixtures
may be sold, you can assure that you are getting
pure propane by filling at an LP refilling station
that sells motor fuel LP. Check local phone
directory yellow pages for these LP gas refilling
stations.
Butane is typically sold only in warmer cli-
mates and is not normally sold in northern states.

LP GAS OUTPUT
Each gallon of liquid LP gas contains approx-
imately 92,000 BTU’s of heat energy; or about
36.2 cubic feet of dry gas for cooking, heating,
water heating and refrigeration.
To find out how long a gallon of LP gas will
last, you should determine the total BTU
input
on all your LP gas appliances in use. Let’s say
you have a furnace that has a 10,000 BTU
input
per hour of operation. A gallon of LP gas would
last 9.2 hours of continuous operation (92,000
BTU’s
¸
by 10,000 BTU’s = 9.2). To estimate
how long a gallon of LP gas lasts, try to deter-
mine what your total daily BTU input is, then di-
vide into 92,000 to arrive at an approximate daily
LP gas consumption.
LP TANK SYSTEM
The storage reservoir for the LP gas system is
a horizontally mounted tank which is permanent-
ly attached to the vehicle frame. The tank is ac-
cessible only from the outside of the vehicle. The
tank supply valve is located near the top center of
the tank, next to the regulator. Before opening the
supply valve, check to be sure all controls for gas
appliances are in the “Off” or “Pilot Off” posi-
tion. If this step is not performed, LP gas could
accumulate inside the motor home creating a fire
or explosion hazard.
*LP Gas tank capacity shown is the usable “full”
LP gas capacity, which is 80% of the tank manu-
facturer’s listed water capacity (w.c. shown in
parenthesis). An LP tank must have at least 20%
of tank volume free to allow for expansion and
proper vaporization of the liquid fuel. The tank is
also equipped with mandatory safety shut-off
equipment that prevents filling above this level.
