Class A
8 – LP Gas System
Power Connection
The LP gas alarm is powered by the coach
batteries. If the auxiliary battery switch is shut off
or the battery cable is disconnected from the
batteries, the alarm will not work. The LP gas
alarm circuit breaker or fuse is located on the 12-
volt house electrical load center (breaker panel).
Because the LP gas alarm is connected
directly to the auxiliary battery, it is always
drawing a small amount of current. Even though
this current draw is slight, it could drain the coach
battery during storage periods when the house
battery will not be charged regularly by the
engine or shoreline. Turn the Aux. Batt switch
OFF to avoid current drain during storage
periods.
Other Combustible Fumes or
Vapors
This alarm is designed to detect the presence
of LP gas, however there are other combustible
fumes or vapors which may be detected by the
sensor. These include: alcohol, liquor,
deodorants, colognes, perfumes, wine, adhesives,
lacquer, kerosene, gasoline, glues, most all
cleaning agents and the propellants of aerosol
cans. Most are lighter than air in their vapor state
and will only be detected when the area is closed
up. Glues and adhesives may exhaust
hydrocarbon vapors for months after they are
applied. They are easily activated by high
temperatures. If you close up an RV coach on a
hot day, the chemicals used in its construction
may be detected for several months after the
coach was manufactured.
Further Information
See the manufacturer’s information entitled
“Your LP Gas Detector” in the Owner InfoCase
for further instructions on nuisance alarms and
care and testing of the LP gas detector.
SAFE USE OF THE LP GAS
SYSTEM
The LP system is designed and built with strict
adherence to federal, state and recreational
vehicle industry requirements for mobile LP gas
equipment.
For your safety, there are many safety devices
and backup systems installed, such as tank fill
overflow valves, an interior LP gas detector/
alarm, and an interior carbon monoxide (CO)
detector/alarm.
LP gas also contains an odor additive that you
can smell if LP is present in the air.
Listed below are a few precautions to observe
that will help you to use the LP gas system safely.
•
Exercise caution at all times. Be familiar with
the distinctive odor of LP gas. If a leak is
suspected, turn off the supply valve
immediately. Have the LP gas system checked
by your dealer or other qualified LP gas
service center.
•
Do not tamper with the LP gas piping system,
pressure regulator or gas appliances. Service
and maintenance of LP gas system
components should be performed only by
your dealer or a qualified LP gas service
center.
•
Never attempt to connect natural gas to the LP
gas system.
•
Have the entire LP gas system inspected for
possible leaks and missing or damaged parts
at each tank filling. Also inspect before and
after each trip, and any time trouble is
suspected.
•
Turn the LP supply valve off when not using
the LP gas system.
WARNING
Never use an open flame to test for gas
leaks. When testing for gas line leaks with
a soapy water solution, DO NOT use a
detergent containing ammonia or
chlorine. These substances may
generate a chemical reaction causing
corrosion to gas lines, resulting in
dangerous leak conditions.
