CHECKING THE LP GAS SYSTEM FOR LEAKS
Road vibration can loosen LP Gas fittings. It is important to check the LP system for leaks at
least every 5,000 miles, and whenever the tank is filled. It is also a good idea to have the
entire LP Gas system checked annually by a qualified LP Gas service representative.
Use the following steps when checking the system for leaks:
1. Open all the windows and vents.
2. Open the gas tank service valve.
3. Use non-ammoniate, non-chlorinated soap solution, or an approved leak detection
solution on all line connections (ammoniate soap solutions can cause cracking on
copper or brass lines and fittings).
4. If a leak is detected, tighten the connection with two open end wrenches until
bubbling stops. DO NOT over tighten, or use excessive force. If the leak continues,
contact the recreation vehicle dealer, or a qualified LP Gas service representative to
have an 11" Water Column Test performed.
WARNING: Never check for leaks with an open flame. The scent of LP Gas (a
garlic-like odor) is actually ethyl mercaptan, an additive that allows you to
detect the presence of a leak, since LP Gas is naturally odorless. Do not rely
upon being able to detect the smell of the gas, as the odor may fade.
ABOUT THE LP GAS DETECTOR
Liquid Propane Gas (LP Gas) is heavier than air and will settle to the lowest point which is
generally the floor of the coach. The detector is also sensitive to other fumes such as hair
spray of which most contain butane as the propellant. Butane, like propane, is heavier than
air and will settle to the floor level where it will be detected. When this occurs, press the reset
button to stop the alert sound for 60 seconds.
Other combustibles which will be detected include alcohol, liquor, deodorants, colognes,
perfumes, wine, adhesives, lacquer, kerosene, gasoline, glues, most of all cleaning agents
and the propellant's of aerosol cans. Most are lighter than air in their vapor state and will only
be detected when the coach is closed up. Glues and adhesives may exhaust hydrocarbon
vapors for months after they are applied. They are easily activated by high temperatures.
The LP Gas Detector is powered by the motorhome coach batteries and/or the inverter. It
draws less current than drawn by one instrument panel lamp. The detector will operate
properly until the battery is drained down to 10 volts. (A low battery condition is 10.4 volts.) If
the power source (battery and/or inverter) is disconnected, or if the power is otherwise
interrupted, the detector will not operate.
The LP Gas Detector has a self check circuit which runs at all times when the detector is
powered. In the event that the circuitry fails, a failure alarm will sound. It is a continuous
series of short beep tones between long intervals and is distinctively different from the alert
sound.
