LP-GAS DETECTOR

About the LP-Gas Detector:
It is important to be aware of the difference between a gas leak versus gas
escaping from an unlit, open burner. Pure propane vapors from a leaking pipe or gas
fitting are heavier than air and will build up their heaviest concentration at the leak
and float down until they mix with air. Gas from open burners is intentionally mixed
with air to induce burning and will dissipate into the air. When mixed with air, the gas
becomes only marginally heavier than air and will expand outward. If a gas burner is
left on, the area around the burner, range, and adjoining counter space will be
combustible and can cause injury and damage if ignited. This condition will exist
for an extended time period and eventually the gas will reach the detector's location
and be detected.
NOTE: The LP detector only indicates the presence of propane gas at its
sensor. Combustible levels of propane gas may be present in other areas.
This detector is intended for the detection of propane gas ONLY.
It has not been tested to detect any other gas. However, other volatile gases
(nuisance gases), most of them flammable in various concentrations, may cause the
detector to alarm. Some products that may cause the detector to alarm are alcohol,
liquor, kerosene, gasoline, deodorants, colognes, propellants used in spray cans and
cleaning solvents. In some cases vapors from the glues and adhesives used in the
manufacturing of the motorhome may also cause the detector to alarm for several
months after the date of manufacture. If it is determined that the detector has false
alarmed because of the above mentioned nuisance gases, reset the detector and air out
the vehicle with fresh outside air.

The LP-Gas detector is required safety equipment in
RVs. American National Standards Institute (ANSI)
A119.2 - Fire & Life Safety 3-4.8 LP Gas Detectors states
"An LP Gas detector must be installed in any RV that
contains an LP Gas appliance and an electrical system.
The LP Gas detector must be listed as suitable for use in
recreational vehicles under the requirement of UL 1484
Residential Gas Detectors, and be installed according to
the terms of its listing."
It detects both LP-Gas and methane gas. Liquefied
Petroleum (LP) Gas is heavier than air; methane gas is
lighter than air. LP-Gas will settle to the lowest point,
020043
generally the floor of the motorhome. Methane gas will
rise. The gas 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,
reset the detector to stop the alert sound.
