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 motor
homes. The capacity of ASME tanks is expressed in gallons. ASME tanks are filled while
the 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.
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 impera-
tive 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
properly.
This propane label should be kept permanently affixed to
your RV.
Servicing or Filling
Have the recreation vehicle checked for leaks at the con-
nections on the propane system soon after the purchase and
the initial filling 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
purged for best performance and must
NEVER BE OVER-
FILLED . This “shut off for re-fueling” label should be kept
permanently affixed to your RV.
NOTE:
Tanks are to be installed, fueled and maintained in
accordance to State and Local codes, rules, regulations or laws.
