Be sure to securely re-install DOT cylinder(s) after they have been removed for lling 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 mo-
torhomes. The capacity of ASME tanks is expressed in gallons. ASME tanks are lled while
the tank is attached to the motorhome by a qualied propane facility. ASME tanks are
equipped with an automatic stop ll valve designed to reduce the potential of overlling.
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. tting from the tank service valve to
the two-stage regulator. Not for use on gas grills and other low pressure devices.
Propane is a true gas compressed into a liquid form. As the fuel is released from the con-
tainer, 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 suf-
cient space inside the container to allow for natural
expansion of gas during warmer weather.
The main shut o valve must be kept closed at all times
unless you are using the propane system or lling 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 o valve by hand
tightening only. Use of tools createto 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.
This propane label should be kept permanently axed
to your RV.
Have the recreation vehicle checked for leaks at the connections
on the propane system soon after the purchase and the initial
lling of each propane cylinder.
When you have a new cylinder lled for the rst time, make
sure your propane supplier purges your new cylinder of trapped
air. Otherwise, an improper mixture of gas and air will make it
impossible to light your propane appliances. No one should be
inside the RV and only the qualied propane service technician
should be near the RV while the propane tank is being lled.
The new propane container must be carefully purged for best
performance and must . This “shut
o for re-fueling” label should be kept permanently axed to
your RV.
Tanks are to be installed, fueled and maintained in accor-
dance to State and Local codes, rules, regulations or laws.
