Fig. 6.1 “If you smell propane” label
When propane container is low, occasionally
there may be a concentration of an onion or
garlic-like odor, which can be mistaken for a
propane gas leak.
After the propane container has been
refueled, the odor will usually disappear. If
not, turn off the valve(s) and have the
propane system inspected by an independent
Jayco dealer or qualified propane service
representative.
PROPANE GAS CONTAINER
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
RV trailers. 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
or 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, user friendly, 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 OPD and ACME type 1
service valve are identified by the triangular
service valve knob.
DOT cylinders are typically marked with “top”
or an arrow to indicate the correct orientation
of the cylinder(s). Do not mount, store or
transport any cylinder other than the in proper
position indicated. Be sure to securely re-
install DOT cylinder(s) to the RV after they
have been removed for filling or replacement.
Always close the service valve and install a
dust cap or plug when transporting or storing
disconnected containers whether full or
empty.
ASME tanks are permanently mounted to the
RV and are commonly used on RV motor
homes. The capacity of ASME tanks is
expressed in gallons. ASME tanks are filled
while the tank is tank is attached to the motor
home by a qualified propane facility. ASME
tanks are equipped with an automatic stop fill
valve designed to reduce the potential of
overfilling. ASME propane tanks are also
equipped with a P.O.L. service valve that is
for connection of the supply hose with a left
hand threaded brass P.O.L. fitting from the
tank service valve to the two-stage regulator.
Not for use on gas grills and other low
pressure devices.
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.
