LP-GAS SYSTEMS - 7
CAYMAN 2007 131
LP-Gas is heavier than air and will settle to
the lowest point in the motorhome. The LP-Gas
detector is also sensitive to other fumes such
as hair spray, which may contain butane as the
propellant. Butane, like propane, is heavier than
air and will settle to the fl oor. Sulfated batteries
(rotten egg odor) will also sound the alarm.
When this occurs, reset the detector to stop the
alert sound.
About the LP-Gas Detector:
Be aware of the difference between a leak
versus LP-Gas escaping from an unlit, open
burner. Pure LP-Gas vapors from a leaking pipe
or fi tting are heavier than air and will build up
heaviest concentration at the leak and fl oat down
to mix with air. LP-Gas from open burners is
intentionally mixed with air to induce burning
and dissipate into the air. When mixed with air,
LP-Gas becomes only marginally heavier and
expands outward. If a burner is left on, the area
around the burner, range and adjoining counter
space is combustible and can cause injury and
damage when ignited. This condition will exist
for an extended time. Eventually, LP-Gas will
reach the detector’s location and cause the alarm
to sound.
NOTE:
The LP-Gas detector indicates the
presence of LP-Gas only at its sensor.
Combustible levels of LP-Gas may be
present in other areas. The detector is
intended for detection of LP-Gas only.
The LP-Gas detector is not designed to detect
other types of gas. However, some products may
cause the detector to alarm, such as alcohol,
liquor, kerosene, gasoline, deodorants, colognes,
propellant used in spray cans and cleaning
solvents. In some cases, vapors from glue and
adhesive 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 ventilate
the motorhome with fresh outside air. Take
precautions to ensure one of these cases has not
masked an actual LP-Gas alarm condition.
The LP-Gas detector draws less current than
one instrument panel lamp and will detect gas
until the battery is drained down to 7.0 Volts. A
voltage higher than 7.0 Volts is needed for the
detector to operate properly. If the power source
is disconnected, or if the power is otherwise
interrupted, the detector will not operate.
The LP-Gas detector has a self-check circuit
running 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.
LP-Gas Detector Operation:
Upon fi rst application of power the LED will
fl ash yellow for three minutes while the detector
is stabilizing. At the end of the start cycle the LED
will turn Green indicating full operation. If the
detector senses unsafe levels of LP-Gas it will
immediately sound an alarm. The LP-Gas detector
draws power from the chassis batteries at a rate of
less than 1/10th of one amp.
CAUTION:
The detector will not alarm during the
three minute warm up cycle.
Testing
Press the TEST switch any time during the
warm up cycle or while in normal operation.
The LED will turn red and an alarm will sound.
Release the switch. This is the only way to test
full operation of the detector.
WARNING:
Test the operation of this detector after
the motorhome has been in storage,
before each trip and at least once per
week during use.
