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 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 cylinder 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 automatically draw fuel 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 down. Regulators that are
not located in compartments have been equipped
with a protective cover. Make sure the regulator
vent faces down and the cover is kept in place
to minimize vent blockage, which could result in
excessive gas pressure, causing fire or explosion.
LPG Tanks
The following procedure outlines the proper method of
removing and installing LPG bottles:
1� Turn the knob on your automatic regulator until
the arrow points to the tank opposite the one to be
removed� Shut off the gas valve on the tank to be
removed�
2� Disconnect the rubber gas line at the tank to be
removed. (The green plastic fitting is a right-hand
thread and no tools should be used�)
3� Turn the large clamping T-handle counterclockwise
until the hold-down bracket is loosened enough
to be able to remove the tank� If your trailer is
equipped with a gas tank cover, the T-handle must
be removed, and then the cover removed before
removing the bottle
WARNING
Do not remove the center hold-down rod.
LPG Tank Installation:
1� Place the tanks in position on the A-frame and
tank cross-member so that it rests on the upper
collar of both tanks with the collar rims engaged
in the grooves on the underside of the bracket� If
your trailer is equipped with a tank cover, it should
be positioned over the tanks 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
tanks are held firmly in place.
3� Test fittings with liquid soap free of ammonia or
chlorine, or products deigned for testing, such as
Snoop® liquid leak detector�
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 appliance, etc�
NOTE
Use only the LPG tanks furnished with your trailer.
If replacement is required, it must be a bottle of the
same size and design.
WARNING
Your LPG tanks must be filled as directed by the
tank manufacturer. Instructions are located on a
decal near the fill valve. The decal must not be
defaced.
WARNING
The LPG tanks are securely mounted on the front
A-frame of your trailer. If these tanks 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.
