NOTE: If freeze-up does occur, shut off the LP Gas at the tank. A frozen regulator may
permit LP Gas to flow at high pressure, resulting in leaks at appliances or in the lines.
If freeze-up does occur, NEVER attempt to thaw with an open flame. A small light bulb
can sometimes be useful to provide heat and aid the thawing process. Once thawed,
be sure to take the proper steps to prevent a reoccurrence. Have the system checked
by your LP supplier if freeze-up continues.
Remember that as outside temperatures drop, the BTU value of the LP Gas is lessened,
since the colder liquid LP in the tanks requires the heat from the surrounding air to vaporize.
This lowering of BTU value can significantly affect the performance of the system. You can
help insure proper performance by keeping your LP tanks as full as possible in cold weather,
and reviewing the BTU/hr plates on LP appliances for proper LP management.
The hoses, pipes, tubes, and fittings used in the LP system are designed to withstand
pressures far exceeding those of the LP system. However, because environment and time
can both contribute to the deterioration of these components, they must be inspected for wear
at regular intervals. Be sure to inspect the hose before each season and when having the
tank refilled. Look for signs of deterioration such as cracks or loss of flexibility. When
replacing the hose or other LP components, make sure to always replace them with
components of the same type and rating (check with your dealer).
Fittings are used to connect the various system components to each other. The P.O.L. fitting
at the end of the LP supply hose is made of brass so that pipe sealants are not necessary to
prevent leaking. It also has a left-handed thread, which means that it is turned clockwise to
remove, and counter-clockwise to tighten. The P.O.L. fitting has been designed to help restrict
the flow of LP Gas in the event of a regulator failure, or hose malfunction.
The LP Gas Leak Detector is powered at all times when the coach battery disconnect switch
is in the ON position. When power is supplied to the detector the green indicator light will
illuminate. After 60 seconds, the detector will begin monitoring the air in the motorhome for
combustible vapors. The propane you use to cook, refrigerate, and heat is combustible.
Should a leak occur, the detector will produce a pulsating alert sound when the gas reaches
the detector. This alert will continue to sound until the gas has dissipated or until the reset
button is pressed. When the alert sounds, open all doors and major windows to air out the
motorhome and turn the gas off at the tank. Do not reenter the motorhome until the alert
stops sounding. If the alert sounds a second time after the gas is turned back on, leave the
gas off and have a qualified LP Gas Dealer or RV Service Center make the necessary
repairs. The reset button only stops the alert from sounding for 60 seconds. This device is
intended for detection of LP Gas ONLY.
