Section 7: Fuel & Propane System
86
DOT propane cylinders must be transported and stored in an
upright position so the pressure relief device will function properly.
Laying a DOT propane cylinder on its side may potentially create a very
dangerous situation.
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.
Before entering a propane or fuel service station make sure all pilot
lights are extinguished. Shut off gas to all appliances by closing the
propane gas main shut off valve. Always shut OFF any engine before
refueling. Do not smoke and do not operate other ignition sources while
refueling.
If you suspect your propane container has been overfilled, contact
your dealer or a qualified propane technician for assistance
immediately. Do not attempt to service a propane container overfill
yourself.

Continued periodic checks of the propane system at 5,000 miles of travel (or at least once
a year), by a qualified propane service representative as part of your normal maintenance is
recommended. Hand tighten the LP gas system valves only, do not use a wrench or pliers as
over tightening may damage the valve seals and cause them to leak.

Propane “container” is a general all-inclusive term used to describe a vessel that is used for
storage and delivery of propane gas.
The most common of these are:
DOT (Department of Transportation) cylinders are transportable and are commonly used on
recreation vehicles. The capacity of DOT propane cylinders is expressed in pounds. DOT
propane cylinders are required to be removed from the RV for filling and must be filled by
weight by a qualified propane facility. DOT Propane cylinders are equipped with an OPD
(over fill protection device) designed to reduce the potential of overfilling. DOT propane
cylinders are also equipped with an ACME service valve that is for connection of the TYPE
1 ACME pigtail hose assembly to the RV two-stage regulator.
The TYPE 1 ACME pigtail hose assembly is a wrenchless, right hand threaded connector
that features a thermally sensitive sleeve and excess flow device. Max output is 200,000
BTU/hr. It is used to connect propane cylinders to regulators, hoses and other fittings. It is
not for use on gas grills and other low pressure devices. DOT cylinders equipped with an
NOTE: All propane lines have been checked with air pressure at
the time of manufacture. Dealers are required to recheck and adjust
pressure before retail delivery.
