2-5
The following conditions can result in potentially dangerous CO
situations:
• Excessive spillage or reverse-venting of fuel-burning
appliances caused by outdoor conditions, such as:
1. Wind direction and/or velocity, including high gusts of
wind.
2. Heavy air in the vent pipes (cold/humid air with
extended periods between cycles).
3. Negative pressure differential resulting from use of
exhaust fans.
4. Simultaneous operation of several fuel-burning
appliances competing for limited internal air.
5. Vent-pipe connections vibrating loose from clothes
dryers, furnaces, or water heaters.
6. Obstructions in or unconventional vent-pipe designs
which can amplify the above situations.
• Extended use of un-vented fuel burning devices.
• Temperature increase that can trap exhaust gases near the
ground.
Symptoms of Carbon Monoxide Poisoning
• Mild Exposure — Slight headache, nausea, vomiting, fatigue
(flu-like symptoms).
• Medium Exposure — Throbbing headache, drowsiness,
confusion, fast heart rate.
• Extreme Exposure — Convulsions, unconsciousness, heart
and lung failure. Exposure to carbon monoxide can cause
brain damage and/or death.
WARNING
Many cases of reported carbon monoxide
poisoning indicate that while victims may be aware
that they are unwell, they become disoriented and
are unable to save themselves by either exiting the
trailer or calling for help. Also young children and
pets may be the first to be affected.
Liquid Propane Gas (LPG) Detector
This alarm has a seven year life — see “end-of-life” notification
in LPG detector manual. Read entire detector manual before
operating unit.
The LPG detector is located in the
kitchen area near the floor. LPG is a
mixture of gases produced and sold
commercially as a fuel for heating
and cooking appliances. LPG is
highly flammable and as a result can
be explosive if ignited under certain
circumstances.
LPG is heavier than air and, if confined in a closed space, will
accumulate close to the floor. The LPG detector is designed
to alert at less than 25% of the legal explosive limit. It provides
visual and audible alerts —sounding an alarm every five (5)
seconds and illuminating the red LED.
Your LPG detector is wired directly to your trailer battery and
incorporates a 1-amp, in-line fuse. It has no internal battery
backup. In normal stand-by mode, the LED indicator will be
green.
LPG Detector — Low Voltage
The operating voltage for the detector is 12 VDC. The actual
voltage supplied to the detector in a recreational vehicle may
drop below the minimum 8 VDC. The detector provides the user
with a low voltage warning before reaching that level and will
provide additional distinct, clear warnings and alarms after the
8 VDC level is reached. However, if available power supplied to
the unit is below the operating voltage of 8 VDC, the detector will
not detect gas or provide protection against dangerous levels of
LPG.
WARNING
Activation of this detector indicates the possible
presence of LPG, which can cause an explosion
and/or fire, causing serious injury or death.
Activation normally indicates a leak in the LPG
installation or an LPG appliance. Extinguish all
open flames, open your windows and door, and
evacuate the unit immediately. Do not activate any
electrical switch. Turn off the LPG at your gas tank.
Do not re-enter your unit until a qualified repair
technician has corrected the problem and certified
the system as safe.
WARNING
It is not recommended that the detector be
disconnected from the battery during periods of
storage. There is a small heater on the sensor of
the device that burns away impurities in the air
during periods of normal use. During periods when
power is interrupted, impurities can build up on the
sensor. When power is returned to the detector,
the detector alarm may activate until the impurities
are burned off. This could take a number of hours,
during which time the alarm will be constantly on.
