6. If a vinyl cylinder cover is provided, slip it over the cylinder and leave the zipper
open (if so equipped).
7. Attach the 1/4" inverted flare x 24" Type 1 pigtail hose to the regulator inlet and the
right hand swivel nut to the cylinder valve.
8. If applicable, close the cylinder cover zipper (if so equipped) up to the hose.
9. Secure the cylinder to the A-frame bracket using the bolts, nuts and washers provided.
Double Cylinder Mounted On A-Frame (if so equipped)
When a second cylinder is installed, a tee check valve is used to replace the 90° elbow at
the top of the regulator and another 1/4" inverted flare x 24" Type 1 pigtail is added. The
regulator stays in the original position.
Double cylinder
1. Place the second cylinder on the A-frame bracket so the cylinder valve is pointed to
the roadside of the folding camping trailer.
2. Secure the second cylinder to the A-frame using the bolts, nuts and washers provided.
3. If a vinyl cylinder cover is used, slip it over the new single cylinder, or a double
cylinder cover may be used in lieu of single covers.
4. Attach the second 24" hose to the tee check valve on the regulator and the right
handed swivel nut to the cylinder valve.
Main Supply Hose – Low Pressure
Attach the main supply hose from the regulator to the brass manifold fitting in the frame of
the trailer. The swivel brass nut on the main hose will be your final attachment.

Several things to remember each time the propane container is removed:
1. Check that ALL fittings are tight.
2. Check that ALL connections are tested with a propane leak detector (or soapy water)
solution.
3. Open the main valve slowly to avoid a fast rush of propane to the excess flow valve
causing propane freeze up. If you experience a propane “freeze-up,” close the main
valve and wait at least fifteen (15) minutes before trying again. Refer to the regulator
manufacturer’s operator manual.
4. Listen carefully - a “hissing” sound longer than one second may indicate a propane
leak. If you feel there may be a leak present, close the valve and contact your dealer
or qualified propane technician for repair assistance.
Replace all protective covers and caps on the propane system after filling. Make sure the
valve is closed and the compartment door is securely latched.
