HOW TO OPERATE:
Your gas leak detector is operating at all times when it is
connected to its power source. This detector will only operate
when supplied with the stated operating voltage.This detector
is a safety device. It must not be connected in such away as
to allow it to be switched off by the use of a wall switch or similar
device,or to become disconnected from its power supply due
to the use of a GFCI protected circuit. When the coach is
equipped with an optional master cutoff switch for storage
only, the detector will be turned off when this switch is turned
OFF. This is acceptable as the coach is not to be used with
the optional master cutoff switch in the off position. When the
coach is powered or turned ON by the master cutoff switch,
the detector's green operating LED will light. After 60 sec-
onds, the detector will begin monitoring the environment for
combustible vapors. The propane you use to cook, refrigerate,
and heat with is combustible. Should a leak occur, when the
gas reaches the detector in sufficient concentration, your
detector will produce a pulsating alarm sound and the RED
alarm LED will light. This alarm will continue to sound until the
gas has dissipated or until the mute button is pressed. When
the alarm sounds, open all doors and major windows to
air out the area, and turn the gas off at the tank. Do not
re-enter the affected area until the alarm stops sound-
ing. If the alarm sounds a second time after the gas is
turned back on, leave the gas off and have a qualified Gas
Dealer or RV Service Center make the necessary
repairs. The mute button only stops the alarm from sounding
for 60 seconds. The alarm will recur if gas is still present.
ABOUT YOUR 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. This 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
manufacture of new RVs may also cause the detector to alarm
for several months after the vehicle's date of manufacture. If
you determine 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. Take these precau-
tions to be sure one of these nuisances has not masked an
actual gas alarm condition.
When installed in an RV, the detector is powered by your RV
battery and/or your converter. This detector draws less current
than one instrument panel lamp. Your detector will operate to
detect gas until your battery is drained down to 8.5 volts. Your
detector must be supplied with a voltage higher than 8.5 volts,
for it to operate properly. When your battery voltage is reduced
below 8.5 volts, your detector's orange fault LED will light. If the
power source (battery and/or converter) is disconnected, or
if the power is otherwise interrupted, the detector will not
operate.
Your gas leak detector has a self-check circuit which runs at
all times while the detector is powered. In the event that the
circuitry fails, a failure alarm will sound and the operating
indicator will cease to light.
