L.p.g. System - Airstream Caravanner 1977 Owner's Manual

L.P.G. System
Your Airstream is equipped with two tanks
for LPG (Liquid Petroleum Gas). LPG burns
with a clean blue flame. There are two
basic types of LPG in common usage:
Butane and Propane.
Butane is widely
used where temperatures are normally
above freezing the year round and Pro¬
pane is used where subfreezing
temperatures are common, since Butane
freezes at 32° as compared to-40° for
Propane
All of the orifices in your
Airstream LPG appliances are of the
universal type which will burn either fuel.
How long a full tank of gas will last is
dependent on usage. In cold weather when
you are using the furnace, large amounts of
hot water, and are doing extensive cooking,
you will naturally use more than you will in
warm weather when you may do limited
cooking. On the average, with normal
cooking and other appliance use, you can
probably count on three weeks service
from each 28-lb. tank.
27, 29 and 31 ft. models are equipped with
an
automatic gas regulator.
Both tanks
are connected to this regulator and are
turned on. Gas is drawn from only one tank
at a time and when the tank being used is
depleted the regulator automatically
switches to the full tank. An indicator on the
regulator points toward the tank being used
to give you a visual reminder when one
tank is empty. Note: The tank in use is not
completely empty until the red warning flag
is fully visible in the indicator window. The
empty tank can be removed for refilling
without disturbing the tank being used.
Simply close the tank valve, disconnect It,
have it refilled and reconnect.
The vent at the bottom of the regulator
must be kept free of any obstruction.
Inspect the vent opening regularly.
To remove the gas tank,
disconnect the
tubing nut with a wrench and loosen the
bar handle which holds the tanks in place.
The tubing nut has a left thread so be
sure to always turn it clockwise to
loosen and counterclockwise to tighten.
When replacing a tank, connect and
tighten the tubing nut before clamping it in
place.
If you have allowed both tanks to run out,
air may have gotten into the lines. In this
event, the air must be forced out through
the lines by gas pressure before you will be
able to light the pilots. Hold a match to the
pilot of the appliance closest to the tanks
until it lights and stays lit. Then move to the
next closest etc. For complete appliance
operating instructions, refer to pages 64-72.
L.P.G. Tanks and Regulator
Close the shutoff valves on the gas
tanks if you smell LP-gas, or if appliance
pilot light fails to stay on.
Contact an LP
gas company service man to correct the
problem.
Additional information on the LPG system is
available in the Airstream Service Manual.
