2022 Interstate 24X
LPG System
Your touring coach is equipped with a permanently-
mounted tank for LPG with a remote fill and remote
gas supply shut off switch� LPG burns with a clean blue
flame. LPG is used where subfreezing temperatures
are common, since it boils at -44°F� Keep in mind at
these temperatures the BTU is lower than at 30°F�
How long a full tank of gas will last is dependent on
usage� On the average, with normal cooking and other
appliance use, you can probably count a few weeks
of usage from the tank, if you are not running your
generator�
If you have allowed the tank to run out, air may
have gotten into the lines� In this event the air must
be allowed to bleed from the lines before lighting
appliances� Follow the appliance manufacturer’s
instructions and light the appliance closest to the LPG
supply tank� Then move to the next closest, etc�
LPG Tank Remote Fill
The LPG tank is filled by accessing the remote
fill hookup located in the compartment behind the
passenger side rear wheels. Be sure the fill is free of
dirt� It may help to remind your LPG supplier to only
use a clean fill hose to fill your tank. Turn off the remote
switch when the LPG system is not in use, as it draws
12-volt current from the batteries�
WARNING
Only certified LPG suppliers should fill the LPG
tank. Turn remote gas supply switch off before
filling or refilling LPG tank.
WARNING
Always shut off the LPG gas when refueling the
touring coach.
Remote Gas Supply Switch
A remote switch for shutting off the gas to all
appliances is located in the rear passenger’s side
compartment� The switch activates an electric solenoid
which opens and closes, shutting the gas off at the
tank. This switch should be turned off during the filling
of the LPG tank or when LP is not needed to fuel
appliances�
Gas lines should be checked periodically for leaks with
ammonia-free soapy water�
WARNING
Be careful when working around electricity, as it
can carry dangerous amperage and cause sparks
or combustion.
NOTE
The electric gas shut-off solenoid closes
automatically when 12-volt power is disconnected.
It will reopen when power is restored.
WARNING
All LP gas appliances must be turned off
during refueling of touring coach fuel tank and
permanently-mounted LPG tank.
WARNING
Do not use open flame to search for problems. If
gas can be smelled, appliance 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.
