Propane Tank Filling
sufficient training to safely fill propane. If you overfill the tank, propane will vent uncontrollably out of the relief valve.
Left to right: relief valve with blue cover, gauge, fill
valve with yellow cap, propane bleeder valve (arrow)
and tank shutoff valve
To fill the tank, first turn off all propane appliances, then turn off
the tank shutoff valve.
We recommend that you find a qualified LPG technician to fill the
tank. The following is an outline of the process to help you
understand and not intended to be complete, nor to substitute
for formal training or instruction.
Attach the fill hose to the fill valve, open the bleeder valve
slightly, and fill the tank to 80% capacity. The stop-fill valve
should automatically stop the filling process. You may also see
liquid propane spit out of the bleeder valve as the tank reaches
the 80% fill level. Stop filling immediately and close the bleeder
valve.
Under no circumstances should anyone fill the tank to more than
80% capacity; doing so can cause liquid propane to flow into the
regulators. If this happens the regulators will have to be
replaced. The relief valve with the blue plastic cover will
automatically vent propane if the tank is overfilled or overheats.
This is not a user-serviceable item; never attempt to remove the
cover, test, or otherwise interfere with the operation of this
valve. Sometimes an overfilled tank will not start venting until the temperature rises. If this valve should open, it is best to
remove all sources of ignition and expeditiously leave the area until propane odor is no longer detectable. Venting unburned
propane is a slightly more advantageous situation than a tank explosion, which is what this valve is designed to prevent.
We recommend that you use only propane from certified LPG retailers.
