SAFETY
Since LP gas is more
dense than air, the
LP gas will naturally
settle to the lowest
point in an enclosed
space. In the motor-
home, this would be
the fl oor.
Because of this, the
CO/LP gas detector
(Figure 2-6) is neces-
sarily mounted close
to the fl oor. To acti-
vate the CO/LP-gas
sensor on this detector for the fi rst time, remove the sensor activation strip, if such was not performed
during the pre-delivery inspection.
If the alarm persists in re-arming and giving further alarms, ventilate the motorhome by opening doors
and windows and then check for possible LP gas leaks. If the leak cannot be readily found, then close
the main valve to the LP tank and turn “o ff ” all gas appliances and then take the motorhome to a quali-
fi ed service technician a ft er the ventilation process is concluded and the doors and windows again shut.
Th is single compact system provides a powerful combined alarm that detects both Carbon Monoxide
(CO) and explosive gases Propane (LPG) and Methane (Natural Gas). Th is detector uses the latest
microprocessor technology combined with two electronic self-cleaning sensors that operate inde-
pendently of each other. Th e combined unit can detect both CO and explosive gases simultaneously.
Carbon monoxide (CO) is a colorless, odorless, tasteless gas which, when breathed, bonds to the he-
moglobin in the red blood cells and, thus, drastically reduces or blocks the transfer of oxygen from the
lungs to the rest of the body.
In su ffi cient concentrations, CO kills by asphyxiation. In lesser amounts, CO makes the victim groggy,
lethargic, and unable to think clearly or quickly.
CO is one of the products of combustion for many materials including petroleum-based products (e.g.,
gasoline, diesel fuel, propane, butane; among others). Since many of the appliances and the engines
associated with the motorhome produce CO in their normal operations, it is necessary to assure that
CO levels do not rise to dangerous levels within the motor home. In su ffi ciently high concentrations,
CO can kill in minutes.
Th e most susceptible people to CO poisoning are unborn babies, small children, pregnant women,
