proper limit by appearance of liquid replacing vapor. At all other times, the
overfill valve should be tightly closed by hand only.
The main valve on the LP gas container should be tightened by hand only, using
caution not to over-tighten. The valve is designed to satisfactorily close with only
a reasonable amount of tightening. Continual over-tightening will eventually
damage the valve and will require its replacement.
A safety check valve is built into the tank to prevent sudden release of large
quantities of gas. The gas valve should be turned on slowly to avoid activating
the safety valve. If gas flow to the trailer is less than normal, it may be
necessary to turn off the gas bottle valve. Turn off all gas appliances in the
trailer. Then wait for a minute and turn on gas bottle valve slowly.
When LP gas containers are filled to the proper level, sufficient space remains
for safe expansion of the vaporized liquid. If your tank becomes overfilled and is
not allowed to "bleed off" before installation with the RV system, it may release
pressure from the relief valve. This can be detected by the strong odor around
tanks. Keep open flames away from this area. It is best to remove the bottle,
take it to a safe area, and "bleed off" the excess pressure by opening the valve
and closing it when discharge has been sufficient.
Handle your LP tanks with care. Vertical tanks must be filled and used in an
upright position. Horizontal tanks must be used only in a horizontal position.
Always fill a horizontal LP gas tank in the vertical position, using the least
amount of pressure possible. Sometimes while filling, the Overfill Prevention
Device (OPD) valve will close. If this occurs, gently tap the cylinder on the
ground to knock the float arm back down. Lowering the fill pressure will help
prevent the OPD valve from closing prematurely.
If you travel alternately on wet roads and in freezing weather, be sure your LP
gas regulator is protected from road spray. If water enters the vent in the
regulator, it may freeze the pressure controlling diaphragm in the open position
so that the container pressure is applied to the appliances - a hazardous
condition. Follow the instructions given by the regulator manufacturer.
CAUTION:
Never smoke while filling LP tanks. Keep the RV away
from immediate filling area when possible or extinguish all gas pilot
lights. When an LP tank gets low, sometimes there is a
concentration of garlic-like odor which may be mistaken for a gas
leak. After changeover to a full tank, the odor usually will soon
disappear.
