SECTION 8
PROPANE SYSTEM
The pigtail hose must be installed to avoid
tension or pulling stress at either end of the
hose. Keep the pigtail hose away from
sharp edges of the cylinder collar, rigid
corners, walls, doors or other compartment
structures including the cover.

Double propane cylinder assembly
(if so equipped)
The containers must be positioned in the tray
with the valves pointing away from the trailer.
The wing nut is placed on the threaded rod to
hold the cross bar down and orient the
containers. The regulator bracket is held in
position by the threaded rod and centers the
regulator between the two cylinders that are
secured at the base on the tray.
Fig. 8.5 Double cylinder assembly
1. Connect the 3/8” low-pressure hose to the
outlet of the two-stage regulator.
2. Place the cylinders on the bracket
provided on the A-frame and secure them
so the outlet of the cylinder valves point
away from the front of the trailer.
3. Using the threaded center rod, position
the regulator bracket. This centers the
regulator between the two cylinders as
they are secured to the base tray.
4. Attach the1/4” inverted flare x 11” Type-1
pigtail hose to the regulator inlet and the
right hand 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:
Fig. 8.7 Main supply hose
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 OEM operator’s 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.
Propane container overfill
Never overfill your propane container above
the liquid capacity indicated on the container.
If a container is overfilled, liquid gas may flow
through the gas regulator, causing it to freeze
and/or introduce dangerous excessive gas
pressure into the lines. In addition, an
overfilled container placed in hot sunlight may
expel excessive gas through the relief valve
