Airstream CLASSIC TRAILER - Manual (Page 63)

AUTOMATIC GAS REGULATOR
All models are 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 black lever 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 : LP gas regulators must
always be installed with the diaphragm vent facing
downward. Regulators that are not in compartments
have been equipped with a protective cover. Make
sure that regulator vent faces downward and that
cover is kept in place to minimize vent blockage,
which could result in excessive gas pressure
causing fire or explosion.
CAUTION : The LPG bottles are securely
mounted on the front “A” frame of your trailer.
If these bottles must be removed for service or
replacement it is important that they be reinstalled
correctly in order to prevent any possibility of their
falling off or becoming dislodged during travel.
LPG BOTTLES
The following step-by-step procedure gives you the
proper method of removing and installing these bottles:
1. Turn the knob on your automatic regulator so the
arrow points to the tank opposite the one to be
removed. Shut off the gas valve on the bottle to
be removed.
2. Disconnect the rubber gas line at the bottle to
be removed. (This fitting has a left hand thread
and turns in the opposite direction to most
threaded fittings.)
3. Turn the large clamping “T”’ handle
counterclockwise until the hold down bracket is
loose enough to remove the bottle. If your trailer is
equipped with a gas bottle cover the “T”’ handle
must be removed, and then remove the cover
before removing the bottle.
WARNING : DO NOT REMOVE THE
CENTER HOLD DOWN ROD.
To Install
1. Place the bottle in position on the “A” frame and
bottle cross member so that it rests on the upper
collar of both bottles with the collar rims engaged in
the grooves on the underside of the bracket. If your
trailer is equipped with a gas bottle cover it should
be positioned over the bottles next. Make sure the
hold down rod projects up through the hole in the
shroud center bracket.
2. Replace the “T” handle and tighten down until the
bottles are held firmly in place.
3. Turn on gas shut off valves and test all fittings
with a soap suds or detergent solution and watch
for bubbles.
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.
Twice a year, or after a long storage period, we suggest
you take your unit in for a checkup and cleaning of the
gas operated appliances.
