PLUMBING
LPG SYSTEM
Your motorhome is equipped with a permanently
mounted tank for LPG (Liquid Petroleum Gas) with a
remote fill. 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 tempera-
tures are normally above freezing the year round, and
Propane is used where subfreezing temperatures are
common, since Butane freezes at 32° F. as compared
to -40° F. for Propane. ALL OF THE ORIFICES IN THE
LPG APPLIANCES ARE OF THE UNIVERSAL TYPE
THAT 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 cook extensively, 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 two to
four weeks of usage from the tank.
If you have allowed the tank 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 can
light the pilots. Hold a match to the pilot of the appli-
ance closest to the tanks until it lights and stays lit.
Then move to the next closest, etc.
LP TANK REMOTE FILL
The LP tank in filled by accessing the remote fill hook
up located inside the LP Fill Door on the roadside of
the vehicle. Be sure the fill is free of dirt. It may help to
remind your LP supplier to only use a clean fill hose to
fill your tank.
WARNING : Only certified LP suppliers
should fill the LP Tank. Turn remote gas supply
switch off before filling or refilling LP tank.
REMOTE GAS SUPPLY SWITCH
A remote switch for shutting off the gas to all appli-
ances is located inside this compartment. The switch
activates an electric solenoid that opens and closes,
shutting the gas off at the tank. The switch rotates ¼
turn. This switch should be turned off during the fill-
ing of the LP tank. NOTE: The electric gas shut-off
solenoid closes automatically when 12-volt power is
disconnected. It will reopen when power is restored
WARNING : All pilot lights and appliances
must be turned off during refueling of motorhome
fuel tank and permanently mounted LPG tank.
Gas lines should be checked periodically for leaks
with ammonia free soapy water.
Do not use open flame. If gas can be smelled, ap-
pliance pilots fail to stay on, or any other abnormal
situation occurs, use the remote supply switch to
shut off the tank valve immediately and call on a
qualified LPG service center or Airstream Service
Center.
CAUTION : Moisture in the LPG tank will cause a
malfunction of the regulator in controlling proper pres-
sure. This may result in the flame lifting off the burner,
or the flame may go out frequently. Many refueling sta-
tions will add approximately ¼ to ½ gallon of alcohol
to lower the moisture temperature. Moisture will then
pass through the regulator without the formation of ice
crystals.
