JAYCO CAMPING TRAILERS
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.
NOTE: Tanks are to be installed, fueled and maintained in accordance to
State and Local codes, rules, regulations or laws.
Propane is a true gas compressed into a liquid form. As the fuel is released from
the container, it changes to vapor which is then used for the operation of the
appliances. Propane will not run through the appliances in the liquid state.
Propane expands 1½ percent for every ten degrees of increase in temperature. It
is imperative to leave sufficient space inside the container to allow for natural
expansion of gas during warmer weather.
The main shut off valve must be kept closed at all times unless you are using the
propane system or filling the propane cylinder. When the cylinder is disconnected
from the hose, install the valve cover that is attached to the container.
Close the propane cylinder main shut off valve by hand tightening only. Use of
tools creates a potential to over tighten the valve (damaging the interior seals on
the cylinder valve seat). If this type of damage occurs, the cylinder will not close
properly.
