Bypass flow is extremely important in the proper
operation of this connection. The flow-limiting device
may activate if the cylinder valve is opened quickly�
When all appliances are off, the bypass flow allows
the pressure downstream from the flow-limiting device
to equalize. When pressure is equalized, the flow-
limiting device will supply normal flow to the system.
Equalization occurs in approximately 5 seconds and,
in most cases, goes completely unnoticed� If, however,
an appliance is left on or there is a leak or open flow
in the system, the bypass pressure will not be able to
equalize and allow the flow-limiting device to reopen.
Symptoms of this condition would be appliances that
light but have lower than normal flame or starve out
from lack of gas, a substantial reduction in the flame
when another appliance is operating, or pilots that are
difficult to light. If this should happen, the following
steps should eliminate the condition:
1� Close LPG cylinder valve�
2�
Extinguish all flames and smoking materials.
3� Be sure all gas appliances, including their pilot
lights, are off�
4� Open LPG cylinder valve slowly� Do not snap open�
5� Wait at least 15 seconds before lighting appliances�
6�
If operational difficulties continue, there may be
a leak in the system� Immediately close the LPG
cylinder valve and have the system inspected by a
qualified RV service technician.
When reconnecting a full cylinder to an auto
changeover regulator, it is not necessary to shut off the
appliances or close the valve of the cylinder already in
service�
WARNING
Leaking LPG may ignite, causing a fire or
explosion, which could result in serious bodily
injury, property damage, and/or death.
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 gas 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 three weeks of
service from each tank�
Automatic Gas Regulator
Your Airstream is equipped with a two-stage automatic
change-over gas regulator that offers the convenience
of automatic changeover from empty to full gas
cylinders� Both tanks are connected to this regulator�
Make sure there is propane in both tanks before you
start� Rotate the white knob on the top-front side of the
regulator toward the cylinder you want to use first. This
will be the service cylinder and the other will be the
reserve cylinder� Slowly open both cylinders valves�
Open both cylinder valves completely, then close about
1/4 turn� This will allow you to easily check to see if
valves are open or closed� The indicator on top of the
regulator will turn bright green� The indicator will stay
bright green as long as there is fuel coming from the
service cylinder� When the service cylinder empties,
the regulator will draw fuel automatically from the
reserve cylinder, providing an uninterrupted fuel flow
to the system� When it switches over, the indicator will
change from green to red� This red color indicates the
service cylinder is empty and needs to be filled.
WARNING
LPG regulators must always be installed with the
diaphragm vent facing downward. Regulators
that are not located in compartments have been
equipped with a protective cover. Make sure the
regulator vent faces downward and the cover is
kept in place to minimize vent blockage, which
could result in excessive gas pressure, causing fire
or explosion.
