Be sure to securely re-install DOT cylinder(s) 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 mo-
torhomes. The capacity of ASME tanks is expressed in gallons. ASME tanks are filled while
the tank is attached to the motorhome 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.
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 con-
tainer, it changes to vapor which is then used for the opera-
tion of the appliances. Propane will not run through the
appliances in the liquid state.
Propane expands 1½ percent for every ten degrees of in-
crease 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 un-
less 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 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 prop-
erly.
This propane label should be kept permanently affixed to
your RV.
Servicing or Filling
Have the recreation vehicle checked for leaks at the connections
on the propane system soon after the purchase and the initial fill-
ing of each propane cylinder.
When you have a new cylinder filled for the first 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 qualified propane
service technician should be near the RV while the propane tank
is being filled. The new propane container must be carefully
